Detailed Description
Fig. 1 is a flowchart of a resource sharing method according to a first embodiment of the present invention. As shown in fig. 1, the method provided by this embodiment includes:
It should be noted that, before step 12, the method further includes:
and step 11, the first router and the at least one second router establishing the resource sharing mode establish a resource sharing list. The resource sharing list comprises software names, abstract information, URLs and router identifications of software stored in the first router and the at least one second router.
Specifically, assuming that the first router is a router a and the second router is a router B, the resource sharing list may be established by the following method, assuming that the resource list of the router a is as shown in table 1 below:
TABLE 1
| Software name | Summary information | URL | Identification of router where software is located |
| Software A | Detail A | URL1 | Router A |
| Software B | Detail B | URL2 | Router A |
The resource list of router B is shown in table 2 below:
TABLE 2
Therefore, the resource sharing list established by the first router and the second router is shown in the following table 3:
TABLE 3
It should be noted that the establishment of the resource sharing list may be implemented by the above method, or may be implemented by other methods, which is not limited in this embodiment.
Step 13, determining whether the URL of the software exists in a resource sharing list according to the software downloading request;
and step 14, if the URL of the software exists in the resource sharing list and the installation package of the software is not on the first router, the first router determines a second router where the software is located according to the URL of the software in the resource sharing list, and sends the software downloading request to the second router.
Specifically, if the URL of the software exists in the resource sharing list and the installation package of the software is on the first router, the first router sends the installation package of the software to the terminal.
If the URL of the software does not exist in the resource sharing list, the first router downloads the installation package of the software from the Internet;
the first router acquires abstract information of the software according to the installation package of the software;
the first router determines whether abstract information of the software exists in a resource sharing list;
and if the abstract information of the software does not exist in the resource sharing list, the first router adds the software name, the abstract information, the URL and the first router identification of the software to the resource sharing list.
Specifically, the original resource sharing list is shown in table 3, and it is assumed that the first router is router a, the software is software D, the abstract information is Detail D, and the URL is URL6, because the software is downloaded by the first router, that is, router a, the router where the software is located is identified as router a, and therefore, these pieces of information are added to the original resource sharing list, so as to form a new resource sharing list as shown in table 4 below:
TABLE 4
And if the summary information of the software exists in the resource sharing list, the first router adds the URL of the software into a URL table entry corresponding to the summary information of the software in the resource sharing list.
Specifically, the original resource sharing list is shown in table 3, assuming that the first router is router a, assuming that the digest information of the software is the same as the digest information of software C, it indicates that the software is software C, assuming that the new URL of software C is URL7, and then adding the new URL of software C to the original resource sharing list, thereby forming a new resource sharing list, which is shown in table 5 below:
TABLE 5
Further, the first router sends the resource sharing list to at least one second router establishing a resource sharing mode with the first router in real time in a broadcasting mode.
Specifically, the first router not only sends the original resource sharing list to at least one second router which establishes the resource sharing mode in a broadcast manner, but also sends the updated resource sharing list to the routers in a broadcast manner, that is, once the first router updates the resource sharing list, the updated resource sharing list is sent to the routers in a broadcast manner.
In the resource sharing method provided by this embodiment, the first router and the at least one second router establish the resource sharing list, and after receiving the software downloading request of the terminal, the first router does not download from the internet immediately, but checks whether the software requested to be downloaded by the terminal exists in the first router and the second router in the resource sharing list, thereby avoiding repeated downloading of the software and effectively utilizing the existing resources.
Fig. 2 is a flowchart of a first embodiment of a method for establishing a resource sharing mode according to the present invention. As shown in fig. 2, the method provided by this embodiment includes:
step 20: sending a request for establishing resource sharing to at least one second router;
step 21: receiving a response of agreeing to establish the resource sharing request sent by at least one second router;
step 22: the first router identifier is sent to at least one second router. The first router Identifier is generated by encrypting a Media Access Control (MAC) address and a Service Set Identifier (SSID) of the first router;
step 23: and receiving the second router identifier sent by at least one second router. The second router identifier is generated by encrypting the MAC address and the SSID of the second router;
step 24: generating a third identifier according to the first router identifier and the received second router identifier, and storing the third identifier in a trust list of the first router;
step 25: and decrypting the identifier of the second router, acquiring the MAC address and the SSID of the second router, and storing the MAC address and the SSID in the trust list of the first router.
Further, the trust list of the first router also includes working state information of the second router, and the working state information of the second router is sent to the first router at a preset time interval after the second router establishes a resource sharing mode with the first router.
Specifically, assuming that the first router is a router a, one of the second routers is a router B, the identifier of the first router is Code a, and the identifier of the second router is Code B, the first router decrypts the second router identifier Code B after receiving the second router identifier Code B, and obtains a MAC address and an SSID of the second router, which are MAC B and SSID B, respectively; generating a third identifier, which is marked as Code AB, according to the own identifier Code A and the received Code B; and finally, storing the MAC address-MAC B of the second router, the SSID-SSID B of the second router and the third identifier Code AB together with the acquired working state information of the second router in a trust list of the first router, wherein the trust list of the first router is shown as the following table 6:
TABLE 6
Further, after the first router receives the software downloading request of the terminal, the method further includes:
judging the working state of the device;
if the working state of the first router is a busy state or a fault state, the first router determines a second router with the working state being an idle state from the trust list;
the first router sends the software download request and the third identifier to the second router.
It should be noted that the sending of the third identifier by the first router to the second router is for the second router to verify the identity of the first router, which will be described in detail below.
It should be further noted that, when there is a situation that the software name of one software only corresponds to one router location identifier in the resource sharing list, the software is backed up to another router, and the resource sharing list is updated. Taking table 3 as an example, specifically, software a is located on router a and router B, software B is located on router a and router B, and software C is located only on router a, when router a fails or is turned off, the terminal cannot request downloading of software C from router a, and in order to avoid this, software C is backed up to another router, for example, router D, so that normal downloading of software C can still be guaranteed in a state where router a cannot normally operate. Suppose that the new URL generated by backing up software C to router D is URL8, and therefore the updated resource sharing list is shown in table 7 below:
TABLE 7
In the resource sharing method provided by this embodiment, a first router establishes a trust list, after receiving a software downloading request of a terminal, the first router first determines its own working state, if the own working state is busy or faulty, a second router whose working state is idle is determined from the own trust list, and sends the software downloading request to the second router, and the second router downloads software; therefore, the processing pressure of the first router is shared, and the load is effectively balanced.
Fig. 3 is a flowchart of a second embodiment of the resource sharing method of the present invention. As shown in fig. 3, the method provided by this embodiment includes:
step 32: and receiving a software downloading request sent by the first router, wherein the software downloading request is sent to the first router by the terminal.
It should be noted that, before step 32, the method further includes:
step 30: establishing a resource sharing mode with a first router;
step 31: a resource sharing list is established with a first router establishing a resource sharing mode. The resource sharing list comprises software names, abstract information, URLs and router identifications of software stored in the first router and the second router.
Specifically, after the resource list is established between the second router and the first router, the second router receives the resource sharing list sent by the first router in a broadcast manner, and after the resource sharing list is updated, the second router receives the updated resource sharing list sent by the first router in a broadcast manner.
Step 33: and sending the installation package of the software to the terminal.
In the resource sharing method provided by this embodiment, a second router and at least one first router establish a resource sharing list, receive a software download request sent by the first router, and then send an installation package of software to a terminal requesting the first router to download the software from its own storage; therefore, the existing resources are effectively utilized, and unnecessary occupation of bandwidth is reduced.
Fig. 4 is a flowchart of a second method for establishing a resource sharing mode according to the present invention. As shown in fig. 4, the method provided by this embodiment includes:
step 40: receiving a resource sharing establishing request sent by a first router;
step 41: sending a response of agreeing to establish the resource sharing request to the first router;
step 42: and receiving a first router identifier sent by a first router. The first router identifier is generated by encrypting the MAC address and SSID of the first router;
step 43: the second router identifier is sent to the first router. The second router identifier is generated by encrypting the MAC address and the SSID of the second router;
step 44: generating a fourth identifier according to the second router identifier and the received first router identifier, and storing the fourth identifier in a trust list of the second router;
step 45: and decrypting the identifier of the first router, acquiring the MAC address and the SSID of the first router, and storing the MAC address and the SSID in a trust list of the second router.
Further, the second router sends the working state information of the second router to the first router at a preset time interval.
Specifically, assuming that the second router is a router B, the first router is a router a, the identifier of the second router is a Code B, and the identifier of the first router is a Code a, the second router decrypts the first router identifier Code a after receiving the first router identifier Code a, and obtains a MAC address and an SSID of the first router, which are MAC a and SSID a, respectively; generating a fourth identifier, which is marked as Code BA here, according to the identifier Code B and the received Code A; and finally, storing the MAC address-MAC A of the first router, the SSID-SSID B of the first router and the fourth identifier Code BA in a trust list of the second router together with the acquired working state information of the first router, wherein the trust list of the second router is shown as the following table 8:
TABLE 8
Further, the resource sharing method provided in this embodiment further includes:
the second router receives the software downloading request and the third identifier sent by the first router; the third identifier is generated by the first router from the first router identifier and the received second router identifier;
and the second router compares the third identifier with the fourth identifier, and if the third identifier is consistent with the fourth identifier, the second router downloads the installation package of the software from the Internet and sends the installation package of the software to the terminal.
It should be noted that the second router compares the third identifier with the fourth identifier to verify the identity of the first router. Specifically, assuming that the second router is a router B, the first router is a router a, the second router identifier is a Code B, the first router identifier is a Code a, the second router generates a fourth identifier which is a Code BA, the first router generates a third identifier which is a Code AB, the second router compares the third identifier Code AB with the fourth identifier Code BA, and if the third identifier Code AB and the fourth identifier Code BA are consistent, the first router is a trusted device in the second router, so that a download request of the first router for the software is executed, an installation package of the software is downloaded from the internet, and the installation package of the software is sent to a terminal requesting to download the software; if not, it indicates that the first router is not a trusted device in the second router, and therefore, the request for downloading the software by the first router is not executed.
In the resource sharing method provided by this embodiment, the second router establishes the trust list, and after receiving the software download request sent by the first router, determines whether the first router is a trusted device in the trust list of the second router, and if so, executes the download request of the first router about the software; therefore, on the premise of ensuring that the first router is a trusted device, the processing pressure of the first router is shared, and the load is effectively balanced.
