Embodiment Construction

[0014] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0015] In view of the small scale of the network this time, this plan divides all substation backbone sites of Jieshou Power Supply Company into area 0, and the plan is as follows figure 1 Shown:

[0016] Such as figure 1 As shown, in OSPF area 0, all sites except Daiqiao substation have at least 2 adjacent sites, which means that each site has 2 different routing egresses, and OSPF can realize two Control of route egress traffic.

[0017] According to the actual link position in the topology diagram, the required modules are calculated as follows:

[0018]

[0019]

[0020]

[0021] According to link statistics, the actual demand for optical cable modules is as follows: 8 multimode modules, 26 10km modules, and 10 40km modules.

Abstract

The invention discloses a county information wide area network topology based on an OSPF protocol, and relates to the field of electric power communication engineering. The topology comprises such aspects as channel configuration, equipment debugging, a networking mode and the like. An erected network takes H3C3600V2 three-layer exchange as a node, an ADSS optical cable as a channel and the OSPF protocol as the basis, and through establishing a convergent point at a main station, each township power supply administration is directly connected with an information ring network via an optical path, such that the data transmission rate of each node is ensured, and the safety and reliability of the network topology are also enhanced. Such a mode is quite convenient for a company with an already established and improved county optical ring network, addition of line erection is unnecessary, a conventional channel is directly employed, and at the same time, the optical port of a switch is directly connected, such that the photoelectric conversion frequency is reduced, and the network reliability is enhanced.

Description

Technical field: [0001] The invention relates to the field of electric power communication, in particular to a county information wide area network topology based on the OSPF protocol. Background technique: [0002] With the full development of the SG186 project of the State Grid Corporation of China, various businesses have formed a great dependence on the network system, so ensuring the stability and smoothness of the network has become the key to the system application. This project plans to re-plan and design the network of the power supply station to improve the availability, security and reliability of the network, and retain a certain degree of scalability to achieve a complete, efficient, high-practicability and reliability network for Meet the needs of various business development. [0003] Common Layer 3 network protocols include RIP, IGRP, OSPF, and EIGRP. Among them, RIP and IGRP take a long time to converge and have poor scalability. EIGRP has the shortest conv...
