The request receiving module 12 is used to receive a VLL establishing request provided by an operation on the user interface 110 by the user. In detail, the operation on the user interface 110 by the user can be that the user inputs or selects the start area and the end area respectively via the start input box 111 and the end input box 112. Therefore, when the user wants to establish the VLL, the user can input or select the start area and the end area of the VLL via the user interface 110 to produce the VLL establishing request. The VLL establishing request includes information of the start area and the end area of the VLL.
The path calculating module 13 is used to determine whether there is one port P of the router device 202 located in the start area is directed to the end area. If yes, namely, there is one port P of the router device 202 located in the start area is directed to the end area, the path calculating module 13 determines the router devices 202 located in the start area and the end area as transmission nodes constituting the VLL.
If not, namely there is no port P of the router device 202 located in the start area is directed to the end area, the path calculating module 13 determines a default router device 202 directed by the router device 202 located in the start area, and further determines whether there is one port P of the default router device 202 is directed to the end area. If yes, the path calculating module 13 determines the router devices 202 located in the start area, the default router device 202, and router device 202 located in the end area as the transmission nodes constituting the VLL.
If not, the path calculating module 13 further determines another default router device 202 directed by the default router device 202 whose ports are not directed to the end area, and further determines whether there is one port P of the another default router device 202 is directed to the end area.
Therefore, the path calculating module 13 executes the above steps repeatedly until the path calculating module 13 determines one port P of one router device 202 is directed to the end area, thus to determine a transmission path starting from the router device 202 located in the start area to the router device 202 located in the end area and passing through or not passing through at least one default router device 202 as the VLL. Namely, the path calculating module 13 determines the router device 202 located in the start area, the router device 202 located in the end area as the transmission nodes constituting the VLL, or determines the router device 202 located in the start area, the at least one default router device 202, and the router device 202 located in the end area as the transmission nodes constituting the VLL.
The path determining module 14 is used to determine which ports P of each router device 202 determined as the transmission nodes of the VLL are ports P to be connected to another port P of another router devices 202 also determined as the transmission node of the VLL, and generate VLL information including the router devices 202 determined as the transmission nodes of the VLL and the ports P to be connected. The path determining module 14 further determines the transmission path constituted by connecting the ports P to be connected one by one as the VLL.
In the embodiment, each router device 202 can connect to a corresponding default router device 202 via a predefined default port P. The path determining module 14 determines the default ports P used to connect to the default router device 202 and the port P directed to the end area of the router devices 202. Therefore, the determined ports P are the ports to be connected.
In detail, as described above, each area network device 200 is located in one corresponding area and corresponds to the area, therefore, the path control device 201 and the router device 202 included in each area network device 200 are also located in one corresponding area and correspond to the area. The path calculating module 13 determines the router device 202 located in the start area and the router device 202 located in the end area according to the start area and the end area included in the VLL establishing request.
The command sending module 15 is used to send the VLL establishing request to the path control device 201 located in the start area when the request receiving module 12 receives the VLL establishing request.
In more detail, when the path control device 201 receives the VLL establishing request, the path calculating module 13 determines whether one port P of the router device 202 corresponding to the path control device 201 located in the start area is directed to end area. If yes, the path calculating module 13 determines the router devices 202 located in the start area and the end area are the transmission nodes constituting the VLL.
If not, namely, if the path calculating module 13 determines no port P of the router device 202 corresponding to the path control device 201 located in the start area is directed to the end area, the command sending module 15 sends the VLL establishing request to a default path control device 201 that is connected to the current path control device 201 located in the start area by default.
As the same, the path calculating module 13 determines whether one port P of the router device 202 corresponding to the default path control device 201 currently receiving the VLL establishing request is directed to the end area. If yes, the path calculating module 13 determines the router device 202 located in the start area, the router device 202 corresponding to the default path control device 201, and the router device 202 located in the end area as the transmission nodes constituting the VLL.
If not, the command sending module 15 sends the VLL establishing request to another default path control device 201 that is connected to the current default path control device 201. The path calculating module 13 determines whether one port P of the router device 202 corresponding to the another default path control device 201 currently receiving the VLL establishing request is directed to the end area.
Therefore, the path calculating module 13 and the command sending module 15 executes the above steps repeatedly, until one port P of one router device 202 is directed to the end area.
As described above, each area network device 200 is set in one corresponding area. The storage unit 102 of the management server 100 further stores relationships between different areas and network addresses of the path control device 201 and the router device 202 of the different area network device 200. The command sending module 15 determines the network address of the path control device 201 according to the relationships, and sends the VLL establishing request to the path control device 201 according to the network address of the path control device 201. In detail, the command sending module 15 determines which path control device 201 needs to receive the VLL establishing request, and determines the area that the path control device 201 needs to receive the VLL establishing request located in. The command sending module 15 then determines the network address of the path control device 201 needs to receive the VLL establishing request according to the relationships stored in the storage unit 102, and sends the VLL establishing request to the path control device 201 according to the network address of the path control device 201. For example, if the path control device 201 needs to receive the VLL establishing request is the path control device 201 located in the start area, the command sending module 15 then determines the network address corresponding to the start area, and then sends the VLL establishing request to the path control device 201 according to the network address of the path control device 201.
The network addresses of the path control device 201 and the router device 202 can be Internet protocol (IP) addresses.
In the embodiment, each default path control device 201 is located in the corresponding area, and the router device 202 connected to the default path control device 201 is the default router device 202. Each path control device 201 can connect to a corresponding default path control device 201 by predefined.
