The area number of the area routing device.

Abbreviation for Data Unit protocol processing unit.

In the embodiment of the present invention, the specified parameter includes at least one of the following: an area number and an interface parameter.

In order to better understand the configuration process of the specified parameters of the network protocol according to the topology diagram, the following description is combined with the preferred embodiment, but the invention is not limited.

After you select a Level-2 device and enter the Level-2 device area Level2Num and Level-1 device start area number Level1BeginNum, the algorithm for calculating IS-IS area planning is as follows:

Step 110: Create a Level-2 device set ArrayL2 selected by the user, and initialize ArrayL2 with the Level-2 device selected by the user, create a variable ArrayL2Length to represent the total number of devices in the set ArrayL2, and create a Level-1 regional device set list ListL1, and ListL1[n] represents The nth Level-1 area device set, create a variable ListL1_Index=-1, create a variable ArrayL2_Index=0;

Step 210: Select a device from the set ArrayL2 in sequence, set the area number of the device to Level2Num, and use Y to represent the device. This step ArrayL2Length is executed cyclically, and the algorithm ends.

Step 310: Select one device from the device directly connected to the device Y, and use X to indicate the selected device. The number of executions of this step is equal to the number of devices directly connected to Y, and the number of executions is returned to step 210;

Step 410: If the device X is in the set ArrayL2, return to step 310 to continue execution;

Step 420: If the device X has an area number, return to step 310 to continue execution;

Step 430: If the device X does not have an area number, ListL1_Index++, set the level of the device X to Level-1-2, the area number to ListL1_Index+Level1BeginNum, and put the device X into the set ListL1[ListL1_Index];

Step 510: Perform the depth-first traversal of the graph with the device X as the starting point. The Level-2 device does not perform traversal. In the traversal process, the device level directly connected to the Level-2 device is set to Level-1-2, and vice versa. -1. All traversed device area numbers are set to ListL1_Index+Level1BeginNum and placed in the set ListL1[ListL1_Index].

It should also be noted that: (1) The depth-first traversal algorithm of the graph is a standard algorithm for computer graphics, which is not specifically described in this application; (2) because the Level-2 device does not traverse, a depth-first traversal is used to find a level. In the area of -1, take Figure 2 as an example. A1, A2, and A3 are Level-2 devices. Select D3 as device X in step 510. Since the Level-2 device is not traversed, a depth-first traversal algorithm is used to find a Level- 1 area equipment collection (D3, D2, D1, D4), as shown in Figure 7;

(3) The Level-2 set is centered, and the remaining Level-1 sets are displayed on the topology map in a circular order around the Level-2 set, and a straight line is drawn between the Level-1 and Level-2 areas to indicate the connection of the area. Relationship, as shown in Figure 3.

(4) The user modifies other attribute configuration templates of each area, and the configuration template provides copying and pasting functions to reduce the workload input by the user.
