Adaptation method in use for syncretizing Internet and system of wavelength division multiplex

Abstract

New layer of data link layer protocol - data link procedure (DLP) is introduced between IP of network layer and WDM in physical layer in the invention to realize syncretizing adaptation between Internet and WDM in order to overcome shortage of current adaptation technique. The method possesses features are: high efficiency of forwarding IP packets, safety and reliability, flux engineering capability, 50 ms protected rearrangement function, realizing exchange between granule level circuit of virtual container and optical wavelength directly, and realizing compatibility between 1Pv4 and IPv6 networks and compatibility to packet voice network. Using safety mechanism, network control management mechanism, flow management mechanism provided by DLP realizes safety management, control management and flow management for IP network. The method makes current IP network transits to united telecom public network in next generation smoothly.

Description

field of invention [0001] The present invention relates to the data transmission field of Internet, it is a kind of adaptation method that is used for Internet protocol (English abbreviation is IP) and wavelength division multiplexing system (English abbreviation is WDM) fusion, is mainly used in various routers (core or High-end switching routers, edge switching routers, access switching routers), various high / medium / low-end Ethernet switches based on packet (packet) switching, multi-service transport platform (abbreviated as MSTP), integrated access equipment at the user end and any interconnected devices related to the Internet. Background technique [0002] According to the relevant information, there is no uniform standard for the adaptation method for the integration of the Internet and WDM in the world. In actual use, there are several methods for the adaptation of the integration of the Internet and WDM by various manufacturers: [0003] (1) Adopt "point-to-point pr...

Problems solved by technology

[0019] The purpose of the present invention is to design a novel IP and WDM fusion adaptation method for the deficiencies and defects of the existing IP and WDM fusion adaptation method. On the one hand, it can realize the WDM at the network layer and the physical layer The direct adaptation between them enables the WDM network to transmit IP directly. On the other hand, it can solve the defects and deficiencies of the IP network in the existing three IP and WDM adaptation methods, and provide a high-speed and efficient IP packet forwarding method for the IP network. The mechanism provides IP networks with fast protection switching functions, traffic engineering capabilities, and network security functions to make IPv4 and IPv6 networks compatible and interoperable, and can support the entire rate range from low-order virtual containers to high-order virtual containers (including cascading). , and is also especially suitable for the use of optical packet switching interfaces. It can realize direct circuit switching based on various virtual containers and synchronous transfer mode particles and direct wavelength switching in all-optical networks, and find a good way out for existing telecommunication transmission resources. Compatibility with the future packet voice transmission network can be realized, and the existing IP network and the existing voice network can be smoothly transitioned to the next-generation unified carrier-class public network using packet switching technology, and the unification of telecommunication transmission and switching can be realized. Greatly reduce the cost of network construction
