Link binding method of intelligent optical network

Abstract

This invention discloses a link binding method in an intelligent light network including the following steps: 1.setting up ppp link on a control channel 2. defining ppp link the IP unnumbered link to make all ppp link in a same network unit to share one IP 3. using MP protocol to bind links on all ppp links between adjacent network units to bind multiple control links together and utilize IP unnumbered to make all communication interfaces of a same network unit to share one IP address. IP and OSPF layers, only one link layer interface is seen between adjacent network units so as to reduce the process to interface on IP layer and bandwidth cost.

Description

field of invention [0001] The invention generally relates to the field of optical network communication, in particular to a method for reducing network overhead and increasing link bandwidth by binding multiple links in an intelligent optical network. Background technique [0002] In an intelligent optical network, there may be multiple transmission media (such as optical fibers) between two adjacent network elements to provide wider bandwidth. figure 1 It is a schematic diagram of communication between adjacent network elements in an intelligent optical network. Such as figure 1 As shown, multiple data channels and one control channel can be accommodated in one optical fiber. The function of the data channel is to transmit services, and the control channel is used to transmit control and management data. The optical network equipment at both ends of the optical fiber generates a control link on the control channel. In this way, multiple data channels and control channels...

Problems solved by technology

[0004] However, there are following disadvantages in the prior art: 1) when the IP protocol is used for data transmission, multiple interfaces will be generated between adjacent network elements, and for switching equipment with more interfaces, it needs management processing There are also many tasks, so the load is heavy; 2) When using the OSPF protocol (Open Shortest Path First Routing Protocol), due to the large amount of data on the interface, a large number of LSAs (Link State Advertisements) will be generated, so that in flooding (that is, the diffusion process of link state notifications), they will occupy a large amount of bandwidth, thereby reducing the network transmission speed; 3) when using IP forwarding, it is possible that all data will pass through the same control channel, resulting in network congestion Case
