As shown in fig. 1, fig. 1 is a flow chart illustrating a method for accessing a network, which may be used in a first router accessing the network using spare bandwidth provided by a second router, according to an exemplary embodiment, the method comprising the steps of:

in step 101, when accessing a wide area network, a second router having a free bandwidth in a specific range to which a first router belongs is determined.

The router in the present disclosure, as an intelligent routing device, may not only have a traditional routing function, but also further include an independent operating system and a disk; the terminal can access the router through the wireless local area network and access the network through the router. The terminal in the present disclosure may be any intelligent terminal having an internet access function, and may be specifically a mobile phone, a tablet Computer, a PC (Personal Computer), a PDA (Personal Digital Assistant), or the like, for example.

In the present disclosure, a plurality of routers may be simultaneously provided within a specific range to which a first router belongs, and when the first router accesses a wide area network (hereinafter, simply referred to as a network), a second router having an idle bandwidth may be determined from the plurality of routers, and when determining the second router, the following manner may be adopted:

first, the first router determines that the second router has spare bandwidth based on a message broadcast by the second router. The second router may broadcast an idle bandwidth notification message in the specific range according to a set time period when the second router has an idle bandwidth, where the idle bandwidth notification message carries idle bandwidth information, the idle bandwidth notification message may be a beacon (beacon) frame, and the idle bandwidth information may be carried by a reserved field in the beacon frame; the first router may listen to various messages broadcast by the second router in real time, and after receiving the idle bandwidth notification message, if idle bandwidth information is obtained from the idle bandwidth notification message, it may be determined that the second router is currently capable of providing idle bandwidth and the amount of bandwidth capable of providing idle bandwidth.

In a second way, the first router actively determines that the second router has idle bandwidth. The first router may actively broadcast an idle bandwidth request message when accessing the network, where the idle bandwidth request message may be a beacon frame broadcast by the first router according to a preset time period; if the second router receives the idle bandwidth request message and the current second router has idle bandwidth, an idle bandwidth response message aiming at the idle bandwidth request message is sent to the first router, the idle bandwidth response message carries idle bandwidth information of the second router, and after the first router obtains the idle bandwidth information from the idle bandwidth response message, the first router can determine that the second router can currently provide the idle bandwidth and the bandwidth amount of the idle bandwidth.

It should be noted that, for convenience of description in the embodiments of the present disclosure, all at least one router capable of providing the spare bandwidth to the first router is referred to as a second router, and the second router is not limited to only one router providing the spare bandwidth to the first router.

In step 102, a relay connection is established with the second router.

In the embodiment of the disclosure, after determining a second router with an idle bandwidth, a first router regularly interacts with the second router based on a WIFI (wireless fidelity) network, the beacon frame may carry information for establishing a relay connection, and after establishing the relay connection according to the interacted beacon frame, the first router may use the idle bandwidth of the second router. The method for establishing the relay connection between the first router and the second router in the embodiment of the present disclosure may include: a Bridge (Bridge) mode, a WDS (wireless distribution System) mode, and the like, and the detailed establishment process may refer to the existing relay connection establishment process, which is not described herein again.

In step 103, access is made to the wide area network by sharing the spare bandwidth of the second router based on the established relay connection.

In the related art, when a first router accesses a network, different access tasks create different numbers of connections, and for the same task, all the created connections are carried through a bandwidth supported by the first router, so that if the bandwidth is wide, the access speed is high; conversely, if the bandwidth is narrower, the corresponding access speed is also slower. In the embodiment of the disclosure, after the first router establishes the relay connection with the second router, the first router may use the idle bandwidth of the second router to access the network simultaneously in addition to using its own available bandwidth. At this time, the first router may calculate a bandwidth ratio between an idle bandwidth of the second router and an available bandwidth of the first router, allocate the number of task connections to the idle bandwidth and the available bandwidth according to the bandwidth ratio, and access the network through the number of task connections allocated to the idle bandwidth and the available bandwidth.

For example, the idle bandwidth provided by the second router to the first router is 5M, the available bandwidth of the first router is 10M, and a certain download task of the first router creates 9 connections, then 3 connections are allocated to the idle bandwidth and 6 connections are allocated to the available bandwidth according to the bandwidth ratio of the idle bandwidth to the available bandwidth of 1:2, and compared with 9 connections which are all carried by the available bandwidth of the first router, after the idle bandwidth of the second router is used, the bandwidth of each connection is increased, and when the download task is executed, the download speed of the first router can be increased.

In addition, during the process of using the idle bandwidth provided by the second router, the first router itself needs to use the idle bandwidth according to the change of the access task when accessing the network. For example, a downloading task that needs to occupy more bandwidth is initially created on the first router, and at this time, 10M idle bandwidth provided by the second router is used; when the first router completes the downloading task and only creates a browsing task for accessing the web page, the idle bandwidth required to be used by the first router is correspondingly reduced, and the idle bandwidth is assumed to be reduced from 10M to 3M. Therefore, in this embodiment of the present disclosure, the first router may send a shared bandwidth notification message to the second router when the usage amount of the idle bandwidth changes, where the shared bandwidth notification message may carry the changed idle bandwidth 3M, and after receiving the shared bandwidth notification message, the second router may update the available idle bandwidth according to the change condition of the idle bandwidth on the first router, for example, after knowing that the idle bandwidth used by the first router changes from 10M to 3M, the second router may provide 7M idle bandwidth for other routers to use, so that the idle bandwidth may be flexibly allocated according to the use conditions of the idle bandwidth of different routers, and the idle bandwidth is reasonably utilized.

By applying the embodiment, the first router can determine the second router with the idle bandwidth in real time in the process of accessing the network, and establish relay connection with the second router, so that the idle bandwidth of the second router is shared to access the network.

Fig. 2 is a flow chart illustrating another method of accessing a network that may be used in a second router providing spare bandwidth to a first router of the access network, according to an example embodiment, comprising the steps of:

in step 201, a relay connection is established with a first router when there is free bandwidth on a second router within a certain range to which the first router belongs.

In the embodiment of the present disclosure, when the first router accesses the network, the router having the free bandwidth in the communicable range thereof may be determined, and after the second router notifies the first router of the free bandwidth thereof, the relay connection may be established with the first router.

The second router may notify the first router of its own idle bandwidth information in the following two ways:

in the first mode, the second router actively informs the first router of the idle bandwidth information of the second router through a broadcast message. The second router can broadcast an idle bandwidth notification message according to a set time period when the second router has idle bandwidth, wherein the idle bandwidth notification message carries idle bandwidth information, the idle bandwidth notification message can be a beacon frame, and the idle bandwidth information can be carried by a reserved field in the beacon frame; the first router may listen to various messages broadcast by the second router in real time, and after receiving the idle bandwidth notification message, may determine that the second router is currently capable of providing the idle bandwidth and the amount of bandwidth of the idle bandwidth that can be provided after obtaining the idle bandwidth information from the idle bandwidth notification message.

Second, the second router may send the idle bandwidth information to the first router upon receiving the request message of the first router. The first router may actively broadcast an idle bandwidth request message when accessing the network, where the idle bandwidth request message may be a beacon frame broadcast by the first router according to a preset time period; if the second router has idle bandwidth when receiving the idle bandwidth request message, sending an idle bandwidth response message for the idle bandwidth request message to the first router, where the idle bandwidth response message carries idle bandwidth information of the second router, and after obtaining the idle bandwidth information from the idle bandwidth response message, the first router may determine that the second router can currently provide the idle bandwidth and the amount of bandwidth of the idle bandwidth that can be provided.

In the embodiment of the disclosure, when determining that the second router has the idle bandwidth that can be shared by the first router, the second router may periodically interact with the first router based on the WIFI network, beacon may carry information for establishing relay connection, and after establishing the relay connection according to the interacted beacon frame, the second router may provide the idle bandwidth of the second router to the first router.

It should be noted that, for convenience of description in the embodiments of the present disclosure, at least one router using the spare bandwidth of the second router is referred to as a first router, and the first router does not limit only one router to use the spare bandwidth provided by the second router.

In step 202, the free bandwidth is provided to the first router over the relay connection such that the first router accesses the wide area network by sharing the free bandwidth.

In the embodiment of the present disclosure, when there are multiple first routers, the second router may provide the idle bandwidth to the first routers according to a preset sharing policy. Wherein the sharing policy may include at least one of the following policies:

in the first strategy, the free bandwidth is equally allocated to each first router. For example, if the second router has 10M idle bandwidth and there are four first routers establishing relay connections with the second router, the second router allocates 2.5M idle bandwidth to each first router.

And the second strategy is to allocate idle bandwidth to each first router according to the bandwidth demand proportion. For example, the second router has 9M idle bandwidth, the two first routers establish relay connection with the second router respectively, and the two first routers notify the second router that 5M idle bandwidth and 10M idle bandwidth are needed respectively, then the idle bandwidth ratio is 1:2, and the second router may allocate 3M idle bandwidth and 6M idle bandwidth to the two first routers respectively.

In the third strategy, the idle bandwidth is distributed according to the order of the intimacy relation value with each first router from high to low. For example, the second router has 5M idle bandwidth, the two first routers respectively establish relay connection with the second router, and the affinities of the two first routers and the second router are "intimacy" and "normal", respectively, then the second router may first provide the 5M idle bandwidth to the first router whose intimacy is "intimacy", and then provide the 5M idle bandwidth to the first router whose intimacy is "normal" when the first router no longer needs the idle bandwidth.

In the embodiment of the present disclosure, while providing the idle bandwidth to the first router, the second router itself may also change the idle bandwidth that can be provided according to the change of the access task when accessing the network. For example, only browsing tasks for accessing a web page are initially created on the second router, and more idle bandwidth can be provided to the first router at this time; and when the second router subsequently creates a downloading task which needs to occupy more bandwidth, the idle bandwidth which can be provided for the first router is correspondingly reduced. Therefore, in the embodiment of the present disclosure, the second router may detect whether the idle bandwidth that can be provided by the second router changes according to a set time period, and when the idle bandwidth changes, send an idle bandwidth change instruction to the first router, where the idle bandwidth change instruction may also be a beacon frame, where the idle bandwidth change instruction carries changed idle bandwidth information that the second router can share with the first router, so that the first router may adjust the number of task connections that can be allocated to the idle bandwidth according to the changed idle bandwidth information, thereby reasonably utilizing the idle bandwidth.

In the embodiment of the present disclosure, although the second router has a function of providing the idle bandwidth to the first router, the holder of the second router may not want to share its own idle bandwidth to other routers in some cases, and therefore the second router may set an option whether to enable the bandwidth sharing function, for example, an enable option may be added to a functional interface of the second router, if the enable option is in a selected state, the second router may provide the idle bandwidth to other routers, and if the enable option is in an unselected state, the second router may not provide the idle bandwidth to any routers.

In addition, when the relay connection is disconnected, the embodiments of the present disclosure may also adopt different manners as follows: when the idle bandwidth provided by the second router to the first router is reduced or the idle bandwidth cannot be provided to the first router, a relay connection disconnection request can be sent to the first router, and the first router can disconnect the relay connection with the second router after the current network access task is completed; or, the first router may send a relay connection disconnection request to the second router when idle bandwidth is not needed, and the second router may disconnect the relay connection with the first router after receiving the relay connection disconnection request. The embodiment of the present disclosure does not limit what manner of disconnecting the relay connection is adopted.

By applying the embodiment, in the process of accessing the network by the first router, the second router with the idle bandwidth can establish relay connection with the first router, so that the first router can share the idle bandwidth of the second router to access the network, and because the first router can share the idle bandwidth of the second router in real time, the first router is not limited by the upper limit of the bandwidth, and the network access speed of the first router can be improved while the idle bandwidth of the second router is fully and flexibly utilized.

In conjunction with the embodiments shown in fig. 1 and fig. 2, referring to fig. 3A, a schematic diagram of an application scenario for accessing a network is shown for the present disclosure according to an exemplary embodiment:

FIG. 3A illustrates a server, which may be a video server provided by a video service provider; family A and family B are neighbors, set up router A in family A, after terminal mobile phone 1 and PC (Personal Computer) 1 in family A pass through WIFI access router A, can visit the server in the network, and in the same way, set up router B in family B, after terminal mobile phone 2 and PC2 in family B pass through WIFI access router B, can visit the server in the network.

The router a and the router B may both enable an idle bandwidth sharing function, and when accessing a network, by establishing a relay connection between the router a and the router B, any router can use an idle bandwidth of an opposite router, and a specific implementation process may refer to the description in fig. 1 and fig. 2. As shown in fig. 3B, a schematic diagram of a function setting interface of an exemplary router in an embodiment of the present disclosure is provided, where the interface includes an enabling option of an idle bandwidth sharing function, and after the enabling option is clicked, the router a or the router B may provide its own idle bandwidth to the other.

Assuming that a PC1 in home a wants to download a certain video file from a video server, the available bandwidth of router a in home a is 10M, router a learns that the idle bandwidth that router B can currently provide is 5M by interacting with router B with beacon frame, and router a may establish relay connection with router B. For a video file to be downloaded by PC1, router a sends a download request to the video server, which creates a download task X for the download request, assuming that the download task X includes 9 connections. At this time, the relay connection is already established between the router a and the router B, the router a calculates that the ratio between the available bandwidth 10M of the router a itself and the idle bandwidth 5M provided by the router B is 2:1, and then the first router allocates 6 of the 9 connections to the available bandwidth of the router a itself, and allocates the other 3 connections to the idle bandwidth.
