As illustrated in figure 1, described information processing method includes：

In step s 110, original packet interception unit 110 is intercepted is passed from the electronic equipment to the content server The original data packet sent；

In the step s 120, redundant field determination unit 120 is determined according to Compression Strategies in the original data packet Redundancy field；

In step s 130, compressed packet generation unit 130 is generated by being compressed to the redundancy field Compressed data packet；And

In step S140, compressed packet delivery unit 140 transmits the compressed data to the network proxy server Packet.

Fig. 3 illustrates information processing method according to the present invention, and Fig. 4 illustrates the network according to the invention agency service Device 200.

Described information processing method is applied to the network proxy server 200 positioned at network-side, the external network proxy services Device is connected to the content server positioned at the network-side, and the network proxy server is also by network connection to being located locally The local proxy server at end, the local proxy server are connected to the electronic equipment positioned at the local side so that described Electronic equipment can access the content server via the local proxy server and the network proxy server.Such as Fig. 4 is illustrated, and the network proxy server 200 includes：Compressed packet receiving unit 210, packed field determination unit 220th, original packet generation unit 230 and original packet delivery unit 240.

As illustrated in fig. 3, described information processing method includes：

In step S210, compressed packet receiving unit 210 is grouped from the local proxy server receiving compressed data；

In step S220, packed field determination unit 220 is determined according to Compression Strategies in the compressed data packet Packed field；

In step S230, original packet generation unit 230 generates original by being unziped it to the packed field Beginning packet；And

In step S240, original packet delivery unit 240 transmits the original data packet to the content server.

It can be seen from the above that using information processing method according to the present invention, local proxy server and network proxy server, Accessed in the electronic equipment positioned at local side via local proxy server and network proxy server in network-side When holding server, in the local proxy server of local side is similarly positioned in, the electronics can be set according to Compression Strategies The standby original data packet to be transmitted to content server is handled, and compresses the redundancy word in the original data packet Section, and there is smaller size of compressed data packet to network proxy server transmission；Also, in the network positioned at network-side In proxy server, after the compressed data packet is received, by performing at the decompression opposite with above-mentioned compression processing Manage to recover the original data packet that the electronic equipment will be transmitted to content server, and be transferred to the content service Device, to perform the relevant subsequent operation of network access by the content server.Therefore, in the present invention it is possible to in electricity The packet transmitted between sub- equipment and content server is compressed, to reduce data involved in transmitting procedure Amount, so as to improve network access speed, and reduces the occupancy of network bandwidth.

As described in the background art, based on TCP connections come perform http network access during in, there are big number According to the Overhead of amount, this will directly contribute network access speed and slow down, and delay the load time of Web content.In the following, This problem existing in theprior art is illustrated in one example.

Fig. 5 a are respectively illustrated with Fig. 5 b belongs to the first http request header that same TCP is connected according to prior art With the second http request header.For example, the first HTTP request and the second HTTP request can input website in a browser（Or Content server）Network address when, two HTTP requests of different objects on the webpage for opening the website.

Specifically, as Fig. 5 a and Fig. 5 b are illustrated, the first http request header is used for content server request of loading First file, i.e. sohuflash_1.js, and the second http request header is used for the second file of content server request of loading, That is global1212.css.

Comparison diagram 5a and Fig. 5 b, it is clear that as can be seen that by reference numeral 501a and 502a in the first http request header The Part I content identified with second identified in the second http request header by reference numeral 501b and 502b Point content is duplicate respectively.That is, carried in the two HTTP requests under belonging to same TCP connections The substantially identical http header of content.

It can be seen from the above that during a TCP connection, for example, once being accessed in the webpage to content server When, due to frequently including a large amount of objects for needing while loading when browsing in a webpage, so electronic equipment is loading Need to send substantial amounts of HTTP request to content server during the webpage.And due to including almost in these HTTP requests Identical http header, so this is resulted in this WEB access process, is transmitted between content server and electronic equipment The Overhead of a large amount of repetitions.The Overhead of this big data quantity takes substantial amounts of network transmission bandwidth, causes network to be visited Ask that speed slows down.

In addition, at present, electronic equipment is usually by wired or wireless communication network, using various communication protocols come from network Upload resource and/or upload resource to network.At present, the communication protocol of mainstream includes General Packet Radio Service（GPRS）Or Person's enhanced data rates global system for mobile communications（GSM）Evolution technology（EDGE）, wideband code division multiple access（WCDMA）And Asymmetrical digital subscriber line（ADSL）.These communication protocols use asymmetrical connection structure, under this configuration, uplink band Width will be significantly smaller than downlink bandwidth（Upstream bandwidth is typically a quarter of downlink bandwidth or so）.Then, deposit in the prior art Influence of the above problem for the uplink link between electronic equipment and content server be often far longer than for The influence of downlink transfer link, so as to delay the whole process that electronic equipment is interacted with content server on the whole.

Therefore, if inventors have contemplated that go out can be to existing in a series of HTTP requests under same TCP connections A large amount of identical Overhead be compressed optimization, then will can be substantially reduced HTTP Overhead for network bandwidth Consumption, and information processing method and information processing system are proposed according to this imagination and asked to solve technology of the prior art Topic.

Hereinafter, information processing method according to embodiments of the present invention and information processing will be described with reference to figure 6 and Fig. 7 System.It will illustrate the embodiment of the present invention in following scene, wherein the electronic equipment in information processing system is chosen for moving Mobile phone, is chosen for the content server for providing web service, by information by the content server in information processing system Processing method is applied to each into content server request of loading webpage from mobile phone in the less uplink of bandwidth During a object.

It should be noted that the present invention is not limited thereto.But it the invention applies also to other one or more Electronic equipment（For example, personal computer, tablet computer, mobile phone, multimedia player, personal digital assistant, ultrabook, Smart television etc.）With for providing various network services（Such as, audio and video chat, game on line, Dropbox storage）Content clothes Uplink and/or any interaction of downlink between business device.

Fig. 6 illustrates information processing method according to embodiments of the present invention, and Fig. 7 illustrate it is according to embodiments of the present invention Information processing system 300.

The illustrated information processing methods according to embodiments of the present invention of Fig. 6 can be applied at the illustrated information of Fig. 7 Reason system 300.As illustrated in figure 7, which includes：Electronic equipment 10, local proxy server 100, net Network proxy server 200 and content server 20.

The electronic equipment 10 is located locally end with the local proxy server 100.Also, in a preferable example, The local proxy server 100 can be integrated into the electronic equipment 10 as a function module and/or hardware unit.Example Such as, when electronic equipment 10 is mobile phone, which can be the operating system of the mobile phone（Example Such as, apple（Apple）The iOS of company, Google（Google）The Android of company（Android）And Microsoft（Microsoft）Company Form phone（WP）Deng）In a software module.

In addition, alternatively, since the electronic equipment 10 and the local proxy server 100 are located at network-side, so both Between transmission bandwidth be untethered, it is therefore contemplated that even if transfer therebetween largely repeat Overhead, It will not have any impact to the bandwidth of magnanimity.At this moment, alternatively, in another example, the electronic equipment 10 and the local Proxy server 100 can be separated equipment.For example, the local proxy server 100 can be integrated in for providing network In the gateway device of connection, so that uniformly one or more electronic equipments 10 into its coverage provide packet pressure Contracting service.

The network proxy server 200 is located at network-side with the content server 20（Or high in the clouds）.Also, in an example In, which can be integrated into the content server 20 as a function module and/or hardware unit In.Since an electronic equipment 10 can send access request to multiple content servers 20, so each content server 20 are required for being integrated with the network proxy server 200, to perform the relevant treatment of the present invention.

Further, since the network proxy server 200 is located at network-side with the content server 20, so between the two Transmission bandwidth be it is untethered, therefore, even if same it is considered that transfer the Overhead largely repeated therebetween, It will not have any impact to the bandwidth of magnanimity.At this moment, alternatively, in another example, the network proxy server 200 and one A or multiple content servers 20 can be separated server, by the same network proxy server 200 of network-side to One or more content servers 20 provide data packet de-compression service, to mitigate in each content server 20 Integrate the installation cost of the network proxy server 200.

The local side can pass through wireless network with the network-side（Alternatively, cable network）And link together.

With Fig. 2, which includes：Original packet interception unit 110, redundant field are true Order member 120, compressed packet generation unit 130 and compressed packet delivery unit 140.In addition, the local proxy server 100 Further include：Compression Strategies acquiring unit 150.

As illustrated in FIG. 6, information processing method according to embodiments of the present invention includes：

In step S310, original data packet is transmitted to content server.

Specifically, when user is wished by electronic equipment 10（For example, mobile phone）Remotely to access content server 20（Such as, there is provided the Website server of web browser service）When, the user can open in the electronic equipment 10 first Browser, and input in the Web address field of the browser network address of the Website server.

Next, the browser of the electronic equipment 10 will be asked based on TCP connections to initiate HTTP to the content server 20 Ask, that is to say, that the electronic equipment 10 by content server 20 send for open the website webpage on some objects A series of HTTP requests.Since the HTTP request is that is, it is to have included without the HTTP request of any processing in the present invention The packet of whole http request header, so hereinafter referred to as original data packet.

In step s 320, original data packet is intercepted.

In the prior art, after electronic equipment 10 transmits original data packet to content server 20, the original number Content server 20 will be transferred directly to by the uplink of network channel according to packet.However, in the present invention, it is being transmitted to Before network channel, the processing for removing redundancy is performed to the original data packet by local proxy server 100.

Specifically, in local proxy server 100, original packet interception unit 110 intercepts inside by electronic equipment 10 Hold the original data packet that server 20 transmits, and other units being sent in local proxy server 100 come pair The original data packet is compressed processing.

In step S330, Compression Strategies are obtained.

Specifically, Compression Strategies acquiring unit 150 obtains the Compression Strategies for being used for that compression to be performed to the original data packet.

In one example, the Compression Strategies can be by the administrator of Website server and the user of electronic equipment according to Experience, used agreement etc. decide through consultation and all remained unchanged during each use afterwards in advance, i.e. the Compression Strategies Without being reacquired every time when original packet interception unit 110 intercepts original data packet.Also, for example, it can be with It is stored in the memory of the electronic equipment 10 or local proxy server 100.At this moment, Compression Strategies acquiring unit 150 can Directly to read the Compression Strategies from memory.

In another example, the Compression Strategies can also be transmitted every time to content server 20 in electronic equipment 10 it is original During packet, or after new TCP connections are set up every time, consult generation by both.

The Compression Strategies that Fig. 8 illustrates according to a first embodiment of the present invention are handled through consultation, and Fig. 9 illustrates according to the present invention One embodiment is used for the unit that Compression Strategies are consulted in information processing system, and Figure 10 a are illustrated according to the present invention in fact The first packet of example is applied, Figure 10 b illustrate compression transmitting request according to embodiments of the present invention, and Figure 10 c illustrate basis The compression transmission response of the embodiment of the present invention, and Figure 10 d illustrate compressed data packet according to embodiments of the present invention.In Fig. 8 In being handled through consultation with the illustrated Compression Strategies of Fig. 9, which generates in network proxy server 200.

As illustrated in fig. 9, compressed to be realized between local proxy server 100 and network proxy server 200 Strategy is handled through consultation, which further includes：First packet interception unit 161, compression request generation unit 162nd, compression request delivery unit 163, compression response receiving unit 164 and Compression Strategies extraction unit 165.Meanwhile the network Proxy server 200 further includes：Compression request receiving unit 261, packet request extraction unit 262, Compression Strategies generation unit 263rd, compression response generation unit 264 and compression response delivery unit 265.

As illustrated in Figure 8, Compression Strategies according to a first embodiment of the present invention handle through consultation including：

In step S410, the first packet is intercepted.

Before electronic equipment 10 is transmitted through the original data packet of overcompression to content server 20, therebetween must Appropriate Compression Strategies must be established, in order to avoid occur causing information to be lost due to the compression processing of mistake.For this reason, the electronics is set Standby 10 can transmit first packet first to the content server 20.For example, first packet can be surveyed Try dedicated packet.

At this moment, in local proxy server 100, the first packet interception unit 161 is in original packet interception unit 110 Before intercepting the original data packet transmitted from electronic equipment 10 to content server 20, first packet is intercepted first, Such as first packet can be such as the illustrated http request headers of Figure 10 a.

Alternatively, which obviously can also be directly actually subjected to content server 20 using electronic equipment 10 First packet in the original data packet of transmission, or can directly produce one by local proxy server 100 Test data packets.

In the step s 420, compression transmitting request is generated by adding compression request information.

Compression request generation unit 162 is believed by adding compression request in illustrated first packets of such as Figure 10 a Cease to generate compression transmitting request, the compression request information is to be used to ask in the local proxy server and the network The information of transmission is compressed between proxy server to each packet.Such as the compression transmitting request can be such as figure The illustrated http request headers of 10b, it is clear that the compression transmitting request with the addition of on the basis of first packet to be used for Compression request information " the Compress for asking Compression Strategies to be consulted:true”.

In step S430, transmission compression transmitting request.

Compression request delivery unit 163 transmits the compression transmitting request to network proxy server 200.At this time, in net The other end of network, in network proxy server 200, compression request receiving unit 261 is in compressed packet receiving unit 210 from originally Before the packet of 100 receiving compressed data of ground proxy server, compression transmitting request is received from local proxy server 100.

In step S440, the first packet of extraction and compression transmitting request.

The extraction from compression transmitting request of packet request extraction unit 262 is transmitted from electronic equipment 10 to content server 20 The first packet and compression request information, the compression request information be used for ask the local proxy server with The information of transmission is compressed between the network proxy server to each packet.

In step S450, Compression Strategies are generated.

Compression Strategies generation unit 263 generates Compression Strategies according to first packet.

In one example, the Compression Strategies generation unit 263 include first packet one or more A information field is determined as one or more reference information fields（Such as, User Agent, Accept-Language, Referer and Accept etc.）；To each reference information field distribution packed field, the size of the packed field is less than institute The size of reference information field is stated, and the packed field is, for example, the identifier for being used to identify the reference information field（It is wrapped Include numeral, letter, symbol etc.）；And generate the pressure for the correspondence for including the reference information field and the packed field Contracting strategy.

In another example, the universality and high efficiency in order to ensure the Compression Strategies in same TCP connections, preferably Ground, the Compression Strategies generation unit 263 can be true in the one or more information fields for including first packet Be set to after one or more reference information fields, further compare from electronic equipment 10 it is receiving, belong to same TCP connections The first packet and other packets between have what reference information field be repeat, and only to repeat it is each A reference information field distribution packed field, so that it is determined that in follow-up transmit process which Overhead compression can be performed to Processing.

In another example, the Compression Strategies can also by Compression Strategies generation unit 263 by rule of thumb data setting or Person is manually set by the administrator of network proxy server 200.

The Compression Strategies specifically can be including being used to distinguish the connection identifier (CID of different TCP connections, can be compressed Overhead expenditure item and header identifier for distinguishing different Overhead etc..

In addition, the Compression Strategies generation unit 263 can also notify network proxy server 200 to store the Compression Strategies, To use later.

In step S460, generation compression transmission response.

Compression response generation unit 264 generates the compression transmission response in response to the compression transmitting request, the compression Transmission response includes the Compression Strategies.Such as compression transmission response can be such as the illustrated http request headers of Figure 10 c, Obviously, compression transmission response is with the addition of on the basis of first packet for determining which Overhead can carry out Compression and its relevant information " Compress-field of respective identifier:Accept-Charset=1,User-Agent=2, Cookie=3,Accept-Encoding=4,Accept-Language=5,referrer=6,Host=7,Proxy- The@1198 " of Connection=8, i.e., with the relevant information of Compression Strategies.

That is, in the Compression Strategies, the expenditure item for the Overhead that can be compressed includes：Accept- Charset, User-Agent, Cookie, Accept-Encoding, Accept-Language, referrer, Host and Proxy-Connection；Their corresponding header identifiers are 1 to 8；And this Compression Strategies is suitable for following HTTP request, The connection identifier (CID of TCP connections belonging to it is 1198.

In step S470, transmission compression transmission response.

Compression response delivery unit 265 transmits compression transmission response to the local proxy server 100.At this time, in net The other end of network, in local proxy server 100, compression response receiving unit 164 is received from network proxy server 200 presses Contracting transmission response, the compression transmission response include the Compression Strategies.

In step S480, Compression Strategies are extracted.

Compression Strategies extraction unit 165 extracts Compression Strategies from the compression transmission response.At this moment, which takes What business device 100 can be informed in that Compression Strategies include is used to distinguish the connection identifier (CID of different TCP connections, can be compressed Overhead expenditure item and header identifier for distinguishing different Overhead etc..

So far, the Compression Strategies between local proxy server 100 and network proxy server 200 consult into Work(, thereafter can be compressed the transferring content for the follow-up HTTP packets for belonging to same TCP connections.That is, After the negotiation of Compression Strategies is completed, the follow-up HTTP between local proxy server 100 and network proxy server 200 In the transmitting procedure of packet, packed field can be used（Compress-field）In identifier（It is for example, digital）Come Substitute corresponding field.

In addition, the Compression Strategies extraction unit 165 can also notify local proxy server 100 to store the Compression Strategies, To use later.

In step S510, the first packet interception unit 171 is intercepted from the electronic equipment to the content service first First packet of device transmission.

In step S520, Compression Strategies generation unit 172 generates the compression plan according to first packet Slightly.The Compression Strategies can specifically include being used to distinguish the connection identifier (CID of different TCP connections, the expense that can be compressed The expenditure item of information and header identifier for distinguishing different Overhead etc..

In addition to the executive agent difference for generating Compression Strategies, the step S520 in second embodiment can be with Step S450 in one embodiment is identical, and therefore omits the detailed description.

In step S530, compression request generation unit 173 in first packet by adding compression request Information generates compression transmitting request, and the compression request information is to be used to ask in the local proxy server and the net The information of transmission is compressed between network proxy server to each packet, and including the Compression Strategies.

In step S540, compression request delivery unit 174 transmits the compression to the network proxy server 200 and passes Send request.At this time, in network proxy server 200, compression request receiving unit 271 is received from local proxy server 100 Compress transmitting request.

In step S550, the extraction from the compression transmitting request of packet request extraction unit 272 is set by the electronics Standby 10 the first packets transmitted to the content server 20 and compression request information, the compression request information is to be used for Request is compressed transmission between the local proxy server and the network proxy server to each packet Information, and including the Compression Strategies.

In step S560, Compression Strategies extraction unit 273 extracts the Compression Strategies from the compression transmitting request, So that network proxy server 200 knows to the Compression Strategies performed in local proxy server 100.

In step S570, compression response generation unit 274 generates the compression transmission in response to the compression transmitting request Response.

In step S580, compression response delivery unit 275 transmits the compression transmission to local proxy server 100 and rings Should.At this time, in local proxy server 100, compression response receiving unit 175 is received from the network proxy server 200 Compression transmission response, and it follows that the Compression Strategies in local proxy server 100 and network proxy server 200 Between consult successfully.

Next, come referring back to Fig. 6 and Fig. 7 continuing on information processing method and information according to embodiments of the present invention Processing system.

In step S340, the redundancy field in original data packet is determined.

After Compression Strategies acquiring unit 150 gets Compression Strategies, redundant field determination unit 120 is according to compression plan Slightly determine the redundancy field in the original data packet.

Specifically, which is determined as waiting to compare by the information field in the original data packet Compared with information field；By the information field to be compared compared with the reference information field in the Compression Strategies；If institute It is identical with the reference information field to state information field to be compared, then the information field to be compared is determined as the original number According to the redundancy field in packet.

Determined for example, working as in the Compression Strategies, the expenditure item for the Overhead that can be compressed includes： Accept-Charset、User-Agent、Cookie、Accept-Encoding、Accept-Language、referrer、 Host and Proxy-Connection；Their corresponding header identifiers are 1 to 8；And the connection identifier (CID of TCP connections is When 1198, which can determine the identifier of the TCP connections of current HTTP request first, if worked as The identifier of the TCP connections of preceding HTTP request is 1198, illustrates current HTTP request and the HTTP request category in Compression Strategies In the Compression Strategies can be applicable in same TCP connections, i.e., current HTTP request.

Next, the information field in the original data packet is determined as waiting to compare by the redundant field determination unit 120 Compared with information field, and then by the information field to be compared compared with the reference information field in the Compression Strategies, Determine in current HTTP request whether to include expenditure item Accept-Charset, User-Agent, Cookie, Accept-Encoding, Accept-Language, referrer, Host and Proxy-Connection.Also, if bag These expenditure items are included, then these expenditure items are determined as in the original data packet by the redundant field determination unit 120 Redundancy field.

In step S350, compressed data packet is generated.

After redundant field determination unit 120 determines redundancy field, which passes through The redundancy field is compressed to generate compressed data packet.

Specifically, the compressed packet generation unit 130 according to the Compression Strategies acquired in Compression Strategies acquiring unit 150 come Determine packed field corresponding with the redundancy field；The redundancy field is replaced using the packed field； Compressed data packet is generated, the compressed data packet includes the packed field.

For example, when the redundant field determination unit 120 is determined to include expenditure item in original data packet Accept-Charset、User-Agent、Cookie、Accept-Encoding、Accept-Language、referrer、 After Host and Proxy-Connection, which believes according to the benchmark included in Compression Strategies The correspondence of field and the packed field is ceased, these expenditure items are replaced with into corresponding header identifier 1 to 8 respectively, And generate compressed data packet.For example, the compressed data packet can be such as the illustrated http request headers of Figure 10 d.

In addition, each pressure that the compressed data packet includes except being included in Compression Strategies can be seen that according to Figure 10 d Outside contracting field, it is also possible to including the information field do not replaced, such as " Accept:text/html,application/xhtml +xml,application/xml;q=0.9,*/*;Q=0.8 " and " If-Modified-Since:Thu,01 Dec 201103: 54:24GMT ", this is because these information fields are not repeated mutually among the different http request headers in same TCP connections Field.

In step S360, compressed data packet is transmitted.

After the compressed packet generation unit 130 generates compressed data packet, compressed packet delivery unit 140 passes through net Network transmits the compressed data packet to network proxy server 200.At this time, in network proxy server 200, compressed packet Receiving unit 210 is grouped by network from 100 receiving compressed data of local proxy server.

In step S370, Compression Strategies are obtained.

After the compressed packet receiving unit 210 receives compressed data packet, Compression Strategies acquiring unit 250 obtains Compression Strategies.

In step S380, the packed field in compressed data packet is determined.

After the Compression Strategies acquiring unit 250 obtains Compression Strategies, packed field determination unit 220 is according to the pressure Strategy contract to determine the packed field in the compressed data packet.

Specifically, the information field in the compressed data packet is determined as to be compared by packed field determination unit 220 Information field；By the information field to be compared compared with the packed field in the Compression Strategies；It is if described Information field to be compared is identical with the packed field, then the information field to be compared is determined as the compressed data packet In packed field.

For example, it is such as the illustrated HTTP requests of Figure 10 d that the compressed packet receiving unit 210, which receives compressed data packet, Header.Also, the Compression Strategies acquiring unit 250 is determined in the Compression Strategies, the Overhead that can be compressed Expenditure item includes：Accept-Charset、User-Agent、Cookie、Accept-Encoding、Accept- Language, referrer, Host and Proxy-Connection；Their corresponding header identifiers are 1 to 8；And TCP The connection identifier (CID of connection is 1198.

At this moment, which can determine the identifier of the TCP connections of current HTTP request first, If the identifier of the TCP connections of current HTTP request is 1198, illustrate current HTTP request and the HTTP in Compression Strategies Request belongs to can be applicable in the Compression Strategies in same TCP connections, i.e., current HTTP request.

Next, the information field in the compressed data packet is determined as waiting to compare by the packed field determination unit 220 Compared with information field, and then by the information field to be compared compared with the packed field in the Compression Strategies, Determine whether include the packed field being identified by identifier 1 to 8 in current HTTP request.Also, if including These identifiers, then the packed field determination unit 220 these identifiers are determined as to the compression in the compressed data packet Field.

In step S390, original data packet is generated.
