Multi-channel data output method and system

Abstract

The invention discloses a method and a system of multi-channel data output, wherein the multi-channel data output method includes the following steps: S802, demultiplex downgoing time-division multiplexing data from a synchronous digital hierarchy network and obtain data frame content corresponding with all channels; S804, store the data frame content corresponding with all channels in corresponding storage space of each channel and generate dispatching request orders when each frame in corresponding channel data frame content is stored n corresponding storage space each time; and S806, respond to the dispatching request order and output the data frame content stored in the storage space corresponding with the channel. The invention can guarantee the channel with large flow rate allocated with enough output bandwidth, and waste no bandwidth on the channel without business.

Description

technical field [0001] The present invention relates to the field of optical communication, and more particularly relates to a multi-channel data output method and system. The present invention relates to the technical field of optical transmission network EOS (Ethernet Over SDH, SDH network transmits Ethernet service) and multi-channel data output scheduling, in particular to the channel queue management and output scheduling of SPI (Sytem Packet Interface, system packet interface) receiving interface method. Background technique [0002] With the rapid development of the Internet, data services will surely become the mainstream of network services. As the most common communication protocol standard adopted by the existing LANs today, Ethernet has become the most widely used LAN technology because of its mature technology, low cost, and flexible and simple application. With the gradual maturity of 1000MHz Ethernet technology and the coming out of 10GHz Ethernet standard, ...

Problems solved by technology

However, this method is only suitable for the static configuration method with fixed channel traffic, and the application of LCAS protocol in EOS technology requires that the bandwidth of each service channel can be dynamically adjusted without service damage. When the traffic of each channel changes, the only The solution is to update the scheduling weight table of each channel in the scheduling controller on time. However, since the service may be composed of many sub-service flows, the transmission path of each sub-service flow in the SDH network is inconsistent, and the delay is uncertain. When to update Scheduling the weight table to ensure the lossless transmission of services has become a difficult problem to solve

On the other hand, when the number of service channels increases to dozens or even hundreds, these static configuration scheduling methods not only make the output bandwidth more wasteful, but also bring great difficulties to the implementation of hardware circuits and consume more hardware resources
