Description

System and method for realizing network reservation storage and reservation server

Technical field

The present invention relates to the field of computer technology, and more particularly to a system and method for implementing network subscription storage and a subscription server. Background of the invention

With the development of computer network technology, resource sharing in the network has become faster and more convenient. The most common resource sharing method currently used is point-to-point (P2P, Peer-to-Peer) technology. P2P technology is different from the shared technology using client/server mode, but has the same features and can be used as a client. / A supplement to server technology.

In the Internet using P2P technology, users can share some resources owned by all P2P software installed in the network through P2P software in their own computers, including processing resources, storage resources, network connection resources, etc. The network can be accessed directly by other computers on the network without going through intermediate entities. In the process of sharing, the computer in the network can be either a resource provider, that is, a server, or a resource acquirer, that is, a client. Therefore, from the perspective of sharing, there is a peer-to-peer relationship between computers with P2P software installed in the network, and data can be directly transferred between computers, instead of the storage resources to be shared by the server transit. Can reduce the load on servers in the network.

Since the computers of a large number of users in the network adopt P2P technology, file sharing between users is very easy, and most of the bandwidth is occupied in network traffic. According to Cache Logic's statistics, in January 2006, BT (Bit torrent), eDonkey (eDonkey) and other shared download software using P2P technology generated network traffic, which has occupied 71% of the entire Internet bandwidth. With P2P technology, users can easily access points via the Internet. Shared files distributed on computers around the world, especially popular files, can spread very rapidly on the Internet through P2P technology.

When P2P technology is adopted in the network, its network logical structure is mainly divided into centralized/semi-distributed structure and fully distributed structure. Among them, in the P2P technology Internet, a centralized/semi-distributed structure is generally adopted. In this type of structure, a management server or a super node is set as a centralized management node, which is responsible for managing shared resources in the network, such as management of shared files. And maintenance, including management file index information, file network link location information, user online status information, and the like. Referring to FIG. 1 , a process of sharing a file resource is illustrated by using a management server in the prior art. In FIG. 1, user A is a downloader of a file resource, and user B is a provider of a file resource.

Step S101: User A sends a query request to the management server.

User A uses his own computer to query the required file resources through the management server; Step S102: The management server sends the information of User B to User A;

After receiving the query request from user A, the management server queries the user's server to query the user B to have the file resources required by user A, and sends the information of user B to user A;

Step S103: Data transmission is performed between user A and user B.

After receiving the information of user B, user A establishes a P2P connection with user B, and user A receives the required file resource from user B.

In the above-mentioned network using the P2P technology, since the computers of the users in the network access and leave the network, the dynamic characteristics are reluctant. Therefore, when the user's computer leaves the network, or the user's computer exits the network for its own reasons, and cannot obtain sufficient user B's file resources in the network in sufficient time, the user A only obtains part of the file of the user B. Resources, the remaining file resources can only be obtained the next time you access the network with User B. However, whether user A and user B's computer can access the network at the same time is not Certainly, it may result in the user B's computer accessing the network, and the user A who requested the download has already logged out of the network, and the file resource cannot be shared to the user A.

It can be seen that although the file resources of the network are rich, there is a problem that the user has a download request and cannot obtain the corresponding resources. Summary of the invention

Embodiments of the present invention provide a system and method for implementing network subscription storage and a subscription server to solve the problem that the user has a download request but cannot obtain a corresponding resource.

In order to explain the present invention in detail to solve the problems in the prior art, various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Referring to Figure 2, a first embodiment of the system of the present invention will be described. In this embodiment, the system includes a management server, a subscription server, and a storage server.

In the system structure shown in Fig. 2, the connection relationship between the storage server and the user is not directly shown. Those skilled in the art will appreciate that the storage server can establish a connection with a shared user to share the data resource by using a plurality of connection methods.

The download user refers to the user who needs to download the data resource from the network. The shared user refers to the user who has the data resource corresponding to the subscription event in the network, and the shared user information refers to the address link information of the shared user, such as the IP address. , port, etc. Data resources are files of various types and the like.

In this embodiment, if user A is the download user, user A may send a subscription message to the subscription server, and the subscription server parses the received subscription message, parses the subscription event in the subscription message, and includes multiple description attributes in the subscription event. . Description attributes include file name keywords, file type, subscription event validity period, file size limit, number of matching downloaded files The upper limit, the file content hash, and so on.

After the resolved subscription event, the subscription server can first query the storage server by using the description attribute in the subscription event, and query whether the storage server has a data resource corresponding to the parsed subscription event, if the storage server is previously Other users download and store such data resources, and the storage server establishes a connection with user A, and user A obtains the required data resources.

Of course, when the user A sends the reservation message to the reservation server, the same reservation message can be sent to the management server at the same time. The management server will parse the subscription message and find the shared user in the network according to the parsed subscription event. If there is a shared user in the network, and the shared user is user B and user C, the management server will share user B and share user C. The information is sent to user A, user A establishes a connection with user B and user C, and user A obtains a data resource. If User A also establishes a connection with the storage server at this time, User A can obtain data resources from User B, User C, and Storage Server at the same time, so that the required data resources can be obtained in a minimum amount of time.

When there is no data resource to be obtained by user A in the storage server, the management server sends the user information of user B and user C to user A and the subscription server. At this time, the user A can directly establish a connection with the user B and the user C through the user information to obtain the data resource. The user A can also send a command to the subscription server, and the reservation server notifies the storage server, and the storage server passes the user B and the user C. Establish a connection and get the data resources that User A needs. After the storage server obtains and stores all the data resources required by the user A, the user A is notified by mail, short message or other forms of instant communication message to download.

Since the user user C is the provider of the data resource, it is impossible to ensure that the user is in the network in real time. If the user: 8, the user C is not in the network, the manager cannot query the user information of the user B and the user C, and thus cannot The shared server information is provided to the subscription server and user A. User A does not share the user information and also leaves the network. The management server will The subscription server sends a notification that there is no shared user information, and after receiving the notification, the subscription server stores the parsed subscription event in the subscription database. If the user B and the user C join the network, the management server sends the user information of the user B and the user C to the subscription server, and after receiving the user information of the user ^ user C, the subscription server determines the subscription database. Whether there is a subscription event corresponding to the user information. Since the subscription event of the user A already exists in the subscription database, the subscription server triggers the storage server to perform the operation, and the storage server establishes a connection according to the user information of the user 8 and the user C, and obtains User A's required data resources. After the storage server obtains and stores all the data resources required by the user A, the user A is notified by a mail, short message or other form of timely communication message to download.

In the foregoing embodiment, when the shared user does not exist in the network, the downloading user may complete the operation of obtaining the data resource by the storage server in the network; when the shared user exists in the network, the downloading user may leave the network. The operation of obtaining data resources is done by a server in the network. The user can obtain the data resource directly from the user by using the user. The user A receives the user information of the user B and the user C sent by the management server, and establishes a connection with the user B and the user C through the user information. Data resources.

In the process that user A obtains the data resource through user B and user C, the management server sends the progress information of the data resource obtained by user A to the subscription server in real time, and the subscription server stores the progress information in the subscription database. If the transmission process of the data resource between the user A and the user B and the user C is interrupted, for example, the user A leaves the network. At this point, the subscription server will discover this situation through no change in the progress information, and the subscription server will notify the storage server to continue to obtain the remaining data resources that User A has not obtained, and the storage server will pass the user information from the management server stored in the subscription server. And establishing a connection with the user B and the user C, and obtaining the remaining data resources not obtained by the user A according to the progress information in the subscription database. After the storage server obtains and stores all the data resources required by user A, A short message or other form of instant messaging message notifies User A to download.

The subscription server in the above system embodiment may be static storage or dynamic loading when running the subscription database. In comparison, the dynamically loaded access and retrieval speed is faster, but the reservation server needs more system memory. For reservation events that have already been completed, they can be stored statically, reducing memory usage. In contrast, if the subscription size is small, the subscription server can be embedded in the management server device, otherwise the network device should be set up separately. It should be noted that if it is operated as a standalone device, in order not to affect the normal network operation of the management server, the subscription server and the management server are connected in the same network segment, that is, connected to the same network switch, taking a network intrusion. Detecting the parallel architecture of the system, the subscription server bypasses the user data on the management server on the network switch port.

The storage server in the foregoing system embodiment may allocate a storage space of different capacity according to the service level of each user and set a threshold, and the size of the file downloaded by the processing user subscription cannot exceed the capacity threshold. The storage server can also index the files it stores for quick access. When the subscription events of the two users are the same, that is, the content of the reservation is duplicated, the storage server can directly copy the file in the user storage space or directly establish an object reference to the file of the repeated demand, so as to timely send the required information to the user. Data resources. The storage server can be a single or clustered storage device or a distributed storage policy. In the case of distributed storage, the system supports the simultaneous assignment of multiple storage servers to download different pieces of files from file providers, enabling fast uploads and downloads using Multi-Source File Transfer Protocol (MFTP).

The system embodiments described above detail the relationships and functions of the various servers in the system, and an embodiment implementing the subscription storage flow is described in detail below. First, the second embodiment will be described, see Figure 3,

Step S301: The download user sends a reservation message;

For ease of transfer, the download user sends the subscription event to the pre-sale in the form of a subscription message. Subscribe to the server and management server.

Step S302: The subscription server parses the subscription message.

The subscription server resolves the subscription event from the subscription message and saves it in the subscription database. In the subscription database, the user record information of all download users and the download record information of the subscribed data resources of the download user are recorded. For example, the download record information may include whether the download has been completely downloaded to the storage server, and the downloaded progress is performed. Information, etc.

Step S303: The subscription server determines whether a corresponding data resource exists in the storage server.

The reservation server determines whether there are other download users before booking the same data resource, whether the data resource is completely downloaded by the storage server and has not been taken away, and if yes, step S304 is performed, and if not, the process ends;

Step S304: The subscription server notifies the storage server, and the storage server sends the data resource to the download user.

Since the data resources stored by other download users are stored in the storage server and have not been taken, the storage server receives the notification from the subscription server, obtains the downloaded user information, and directly copies the corresponding data resources and sends them to the download user.

Step S305: The management server parses the subscription message.

The management server parses the subscription message and gets the subscription event.

Step S306: The management server determines whether there is shared user information.

The management server determines whether there is shared user information in the network that has a data resource corresponding to the subscription event. If yes, step S307 is performed, and if not, step S308 is performed.

Step S308: Notifying the downloading user;

The management server notifies that there are no shared users on the network.

Step S307: The management server determines whether the download user needs to download; After the shared user information exists in the network, if the downloading user wants to establish a connection download through the shared user, step S309 is performed, and if the downloading user does not perform the connection, step S310 is performed.

Step S309: Download the user to connect;

The download user obtains the shared user information through the management server, establishes a P2P connection with the shared user, and downloads the required data resources.

Step S310: The storage server performs downloading.

If the download user does not establish a connection with the shared user, the download user may leave the network. At this time, the management server notifies the subscription server, and attaches the shared user information in the notification. After the subscription server receives the shared user information, the storage server is triggered. Use the shared user information to establish a P2P connection with the shared user, and obtain the data resources needed to download the user.

After the downloading user obtains all the data resources, the step S311 is performed after the step S304, the step S309, and the step S310.

Step S311: updating the subscription database;

The subscription database is updated, the subscription events in the subscription database are deleted, and the relevant records are recorded.

After the storage server obtains and stores all the data resources required by the downloading user, the downloading user is notified by a mail, short message or other form of timely communication message, and the downloading user obtains the data resource from the storage server after receiving the notification.

In the first embodiment, after the downloading user submits the subscription event to the subscription server, the downloading event can be directly downloaded by the storage server, and the storage server is all downloaded, and then the downloading user is notified. Step S304 and step S309 can be performed simultaneously, which speeds up the downloading speed of the downloading user and saves time for the downloading user to obtain all the data resources. In step S309, when downloading the user for downloading, if the downloading user leaves the network after not obtaining all the data resources, the downloading user only obtains a partial segment of the data resource, and in this case, the solution is solved by the second embodiment. Scheme, see Figure 4,

Step S401: The download user sends a reservation message;

Step S402: The subscription server parses the subscription message.

Step S403: The subscription server sends the subscription event to the management server.

The subscription event is sent to the management server because the subscription server determines that the data resource required by the user is not downloaded in the storage server;

Step S404: The management server determines that the shared user information exists.

Step S405: The management server determines that the download user downloads by itself;

Step S406: Download the user to connect, and obtain the data resource;

The download user establishes a connection with the shared user and obtains a data resource;

Step S407: The management server determines whether the download user goes offline.

In the process of downloading the user to obtain the data resource, the management server continuously determines whether the download user is still in the network, if yes, continues to determine; if not, proceeds to step S408; step S408: the management server notifies the subscription server;

Since the downloading user may disconnect the network for various reasons, the management server will notify the subscribing server that the downloading user is offline, that is, the downloading user has disconnected from the network, and notifies the corresponding shared user information and progress information of the subscribing server. Wait;

Step S409: The subscription server triggers the storage server download;

Since all P2P systems support file download tracking and record progress information, the subscription server triggers the storage server reference progress information, establishes a connection with the shared user by using the shared user information, and obtains the remaining fragments of the data resource that are not obtained after the download user goes offline from the shared user. .

Step S410: Update the subscription database.

After the storage server obtains and stores the remaining fragments of the data resource after the download user goes offline, the download user is notified by mail, short message or other forms of timely communication message, and the download user obtains the remaining fragments of the data resource from the storage server after receiving the notification. . The above two embodiments are all sharing users in the network, downloading users leaving the network or downloading users after disconnecting the network during the download process, how the network downloads and saves data resources for the downloading users. Since both the shared user and the downloading user are reluctant in the network, there may be a case where the downloading user goes online to submit the subscription event, and the shared user is not in the network, as in steps S306 and S308 in the first embodiment, but after The shared user goes online. At this time, if the download user has left the network or is still in the network, the solution for such a situation is explained by the third embodiment, as shown in FIG. 5 .

Step S501: The management server determines whether a shared user joins in the network.

The management server continuously determines whether there is a shared user joining in the network. When it is determined that a shared user joins the network, the management server sends the shared user information to the subscription server;

Step S502: The subscription server retrieves the subscription database.

After receiving the shared user information, the subscription server retrieves the subscription database according to the data resources owned by the shared user. Since the subscription server has previously stored the subscription event in the subscription database, and the subscription event and the data resource have a mutual correspondence, Retrieves the corresponding subscription event in the subscription database through the data resource.

Step S503: determining whether there is a reservation event;

Retrieves whether a subscription event exists in the subscription database through a data resource. If yes, step S504 is performed, and if not, it ends.

Step S504: determining whether the download user is online;

There is a corresponding subscription event in the subscription database, indicating that the download user needs to obtain the corresponding data resource from the shared user. At this time, it is first determined whether the download user is in the network, that is, whether it is online. The subscription server sends the download user information to the management server, and the management server determines whether the download user is online. If online, step S505 is performed, and if not, step S507 is performed. Step S505: The management server determines whether the download user establishes a connection; if yes, step S506 is performed, and if no, step S507 is performed.

Step S506: The download user establishes a connection;

When the download user needs to download it himself, the download user can obtain the shared user information through the subscription server or the management server, and establish a P2P connection with the shared user to obtain the required data resources.

Step S507: The storage server performs downloading.

If the download user is not online or the download user cannot establish a connection with the shared user for other reasons, the management server notifies the subscription server, and the storage server is triggered by the subscription server, and the storage server establishes a connection with the shared user through the shared user information in the subscription server. Download all the data resources your users need.

Step S508: Update the subscription database;

After the download is complete, the subscription database is updated, the subscription events in the subscription database are deleted, and the relevant records are recorded.

In the third embodiment, the downloading user selects to download by itself, that is, step S506 is performed. In the process of downloading the user to obtain the data resource from the shared user, if the downloading user disconnects from the network, the step in the second embodiment may be adopted in this case. S407 to step S410 are solved; of course, there may be a case that after the connection between the download user and the shared user is established, since the shared user leaves the network, the download user only leaves part of the data resource and then leaves the network, and then the shared user joins again. Network, for this case, the solution is explained by the fourth embodiment. See Figure 6,

Step S601: The management server notifies the subscription server; Since the shared user leaves the network, the download user and the shared user disconnect, the management server will notify the subscription server that the shared user is offline, that is, the shared user has disconnected from the network, and notifies the reservation server of the progress information before disconnection;

Step S602: The subscription server records the received information.

The subscription server logs the received information to the subscription database and saves it with the corresponding subscription event;

Step S603: The management server determines whether there is a shared user joining in the network. The management server continuously determines whether there is a shared user joining in the network. When a shared user joins the network, the management server sends the shared user information to the subscription server. The newly added shared user may be the same shared user before the last disconnection, or may be a different shared user, as long as the shared user has the data resources required to download the user.

Step S604: The subscription server retrieves the subscription database;

After receiving the shared user information, the subscription server retrieves the subscription database according to the data resources owned by the shared user. Since the subscription server has previously stored the subscription event in the subscription database, there is a correspondence between the subscription event and the data resource. Ability to retrieve the corresponding subscription event in the subscription database through the data resource.

Step S605: determining whether there is a reservation event;

Retrieves whether a subscription event exists in the subscription database through a data resource. If yes, indicating that the download user needs to obtain the corresponding data resource from the shared user, step S606 is performed, and if not, the process ends.

Step S606: determining whether the download user is online;

At this point, first determine whether the download user is on the network, that is, whether it is online. The reservation server sends the download user information to the management server, and the management server determines whether the download user is online. If it is online, step S607 is performed, and if it is not online, step S609 is performed.

Step S607: The management server determines whether the download user establishes a connection. If yes, step S608 is performed, and if no, step S609 is performed.

Step S608: The download user establishes a connection;

When the download user needs to download it himself, the download user can obtain the shared user information through the subscription server or the management server, and establish a P2P connection with the shared user to obtain the remaining fragments of the data resource that were not obtained after the last disconnection.

Step S609: The storage server performs downloading.

If the download user is not online or the download user cannot establish a connection with the shared user for other reasons, the management server notifies the subscription server that the subscription server will look in the subscription database and find the progress information of the downloaded user recorded in the corresponding subscription event. The subscription server triggers the storage server, and the storage server establishes a connection with the shared user by sharing the user information in the subscription server, and obtains the remaining segments of the data user that the last downloaded user did not obtain the data resource after disconnecting from the shared user according to the progress information.

Step S610: Updating the subscription database;

After the storage server obtains and stores the remaining fragments of the data resource after the download user goes offline, the download user is notified by mail, short message or other forms of timely communication message, and the download user obtains the remaining fragments of the data resource from the storage server after receiving the notification. .

Since the shared user joins the network during the working process, the number of times the subscription server receives the shared user message may be very frequent. To reduce the burden on the subscription server, multiple subscription servers may be established to implement load balancing. Multiple subscription servers may be used. Cluster or distributed structure; The threshold of the number of shared user information can also be received according to the time period or the threshold for receiving the shared user information.

In the various embodiments described above, the subscription server has a critical role in implementing the network subscription storage function. Regarding the composition of the reservation server, it is carried out by the sixth embodiment of the present invention. Description, see Figure 7,
