Specific embodiment

The invention is further described in the following with reference to the drawings and exemplary embodiments, which are illustrated in the accompanying drawings, in which the same or similar reference numerals are used to refer to the same or similar elements or elements having the same or similar functions. . The embodiments described below with reference to the drawings are intended to be illustrative of the invention and are not to be construed as limiting. Further, if a detailed description of a known technique is not necessary to show the features of the present invention, it will be omitted.

FIG. 1 is a schematic flowchart of a method for implementing bandwidth sharing between routers according to an embodiment of the present invention. As shown in FIG. 1, the method includes:

Step S110, setting a first communication module and a second communication module in the router.

Step S120: The first communication module is connected to the WAN interface of the router, and the first communication module is connected to the second communication module. The second communication module is used to connect with at least one other router connected to the WAN, and the WAN interface is used. Connected to the WAN.

Step S130, when the first communication module receives the data request from the terminal device accessing the router, it is determined whether other routers need to cooperate to process the data request.

For example, when a terminal device that accesses the router such as a mobile phone, a computer, or a tablet computer transmits a data request for downloading a song or browsing a web page, the above determination is performed.

Step S140, if the determination is yes, the data request is sent to the one or more other routers connected to the second communication module through the second communication module.

Step S150, receiving, by the second communication module, data corresponding to the data request returned by one or more other routers.

It can be seen that, in the method shown in FIG. 1, an interconnected first communication module and a second communication module are disposed in the router, wherein the first communication module is connected to the WAN interface of the router, and the second communication module is For connecting to at least one other router connected to the wide area network, the WAN interface is connected to the wide area network, so that when the first communication module receives the data request from the terminal device accessing the router, it is determined whether other routers need to cooperate to process the data. Requesting, if the determination is yes, sending the data request to the one or more other routers connected to the second communication module through the second communication module, and further receiving the data returned by one or more other routers through the second communication module Request the corresponding data. The technical solution can use the router to obtain data corresponding to the data request, such as downloaded pictures and videos, in the case that other routers need to cooperate to process the data request, effectively utilizing the idle bandwidth on other routers, and is more efficient. The data request sent by the terminal device is processed.

In an embodiment of the present invention, the method shown in FIG. 1 further includes: transmitting, by the first communication module, the data request to the wide area network interface; and receiving, by the first communication module, data corresponding to the data request returned by the wide area network interface.

In this embodiment, the router can still send the data request to the WAN interface through the first communication module and receive the data corresponding to the data request returned from the WAN interface, that is, the router still retains the access network and performs The function of route distribution.

In an embodiment of the present invention, in the above method, the data corresponding to the data request returned by the one or more other routers is different from the data corresponding to the data request returned by the WAN interface.

Since the router can obtain corresponding data according to the data request from its own WAN interface, it can also obtain corresponding data according to one or more other routers. If the data obtained by the two methods overlap, the resource is wasted. Contrary to the original intention of the design of the present invention. For example, the user sends the data request of the picture A through the terminal device. If the data of all the pictures A is obtained in the above two ways, or the data of the partial picture A is obtained, but overlaps, the data is not compared and integrated. Trouble, also wasted bandwidth. Therefore, the data corresponding to the data request returned by one or more other routers should be different from the data corresponding to the data request returned by the WAN interface.

In an embodiment of the present invention, the method further includes: transmitting, by the first communication module, data corresponding to the data request to the terminal device that initiates the data request.

After obtaining the data corresponding to the data request, it is also required to be sent to the terminal device that initiates the data request. Since the data request sent by the terminal device is received through the first communication module, that is, the router passes the first communication module and The terminal device establishes a connection relationship. Therefore, in the embodiment, the data corresponding to the data request is sent to the terminal device that initiates the data request by the first communication module.

In an embodiment of the present invention, in the method shown in FIG. 1, determining whether other routers are required to co-process the data request further includes: a data request amount according to the data request and a data transmission on the WAN interface. The bandwidth is transmitted to determine whether other routers need to cooperate to process the data request.

Since data communication with other one or more routers also takes time and considers the data transmission rate problem of data communication with other one or more routers, in this embodiment, the data request amount according to the data request and the WAN interface The data transmission bandwidth is used to determine whether other routers are required to co-process the data request. For example, the data request sent by the terminal device corresponds to the page information of a certain webpage, and the data request amount does not exceed 10 MB, and the data transmission bandwidth of the router's WAN interface is 100 MB, that is, the data volume of 12.5 MB can be downloaded per second. Then, the data corresponding to the data request can be obtained by using the data transmission bandwidth on the WAN interface in less than one second, and no other routers are required to co-process the data request. If the data request is a 30G online game client installer, the router in the above example needs other routers to co-process the data request. That is, if it is determined that no other routers are required to co-process the data request, the data request is only sent to the WAN interface.

In an embodiment of the present invention, the method shown in FIG. 1 further includes: when the second communication module receives a data request from another router, determining whether the router has set a sharing bandwidth limit parameter; if yes, sharing the bandwidth limit Within the bandwidth defined by the parameter, the data corresponding to the data request is obtained through the WAN interface and returned to other routers; otherwise, within the data transmission bandwidth of the WAN interface, the data corresponding to the data request is obtained through the WAN interface and returned to Other routers.

Similarly, this router can also share bandwidth for other routers. However, in order to ensure the normal use of the router, a shared bandwidth limit parameter may be set, and bandwidth sharing is performed for other routers within the bandwidth defined by the limit parameter, that is, data corresponding to the data request is obtained through the WAN interface and returned to other routers. For example, if a user is playing an online game, he or she needs high bandwidth. Although the data transmission bandwidth on the WAN interface on the router connected to the terminal device is 100 MB, but can only be shared to other users by 20 MB, the sharing bandwidth limit parameter setting can be set. Is 20. When the user plays a stand-alone game, without using the network, the sharing bandwidth limit parameter can be set to 0 (or the sharing bandwidth limit parameter is not set), so that all 100 MB bandwidth can be shared to other routers. Preferably, multiple sharing bandwidth policies can be set for the user to edit and select, for example, setting the sharing bandwidth limitation parameter in some time periods, setting the sharing bandwidth limitation parameter in other time periods, and receiving some data sent by the terminal device. Automatically open a sharing bandwidth policy after request, and so on.

In an embodiment of the present invention, in the method shown in FIG. 1, the sending of the data request to the one or more other routers connected to the second communication module by using the second communication module further includes: the second communication module receives the When the data request of the first communication module is requested, one or more routers are selected from at least one other connected router connected to the wide area network, and the data request is sent to the selected one or more routers.

When the second communication module can connect to multiple routers, because these routers also have access to the wide area network, and the data transmission bandwidth on the WAN interface is different, the data transmission bandwidth can be based on the data request amount and other routers. And the like, selecting one or more routers from at least one other connected router connected to the WAN, and sending the data request to the selected one or more routers. For example, the second communication module is connected to multiple routers, wherein the data transmission bandwidth on the router A is 100 MB, the data transmission bandwidth on the router B is 1 MB, and the router C is not connected to the wide area network, then the data request can be preferentially sent to the router. A.

In an embodiment of the present invention, the method further includes: setting a transmission bandwidth value for each data request when the second communication module receives the plurality of data requests from the connected plurality of routers; for each data request Within the range of the corresponding transmission bandwidth value set, the data corresponding to the data request is obtained from the WAN interface through the first communication module and returned to the corresponding router.

Since the router can also share bandwidth to multiple other routers at the same time, it is necessary to formulate a processing strategy for data requests sent by multiple routers, otherwise the sharing efficiency will be seriously affected. Preferably, the data bandwidth request amount of each data request may be used to set a transmission bandwidth value for each data request, so that the data is obtained from the WAN interface through the first communication module within a range of the corresponding transmission bandwidth value that is set. Request the corresponding data and return it to the appropriate router. For example, the second communication module receives the data request of the router A, the router B, and the router C respectively, wherein the bandwidth available for sharing by the router is 100 MB, and the data request amount of the data requested by the router A is 500 MB, and the router B sends the data request. The data request volume of the corresponding data request is 300 MB, and the data request amount of the data requesting by the router A is 200 MB, and the transmission bandwidth values of 50 MB, 30 MB, and 20 MB can be set for the routers A, B, and C, respectively.
