Problems solved by technology

[0007] However, AS technology is still in the standard formulation stage, and there is no ready-made chips in the industry, and it will take some time before mature applications. At the same time, since AS is a brand-new interface, service nodes and switching nodes are required to support AS interfaces, and a large number of chip types need to be added. , the cost is also higher

Embodiment Construction

[0024] The main idea of ​​the present invention is to unify various switching nodes such as TDM switching, IP switching and FC switching on a set of backplane bus, flexibly allocate switching network resources through the switching node control module, and allocate different switching node resources according to different requirements , so as to unify various switching nodes into one set of backplane bus.

[0025] Taking multiple switching node resources such as TDM, FC and IP combined into one slot of a single board as an example, the present invention will be further introduced in conjunction with the accompanying drawings and typical embodiments, but this is not intended to limit the present invention.

[0026] Such as figure 2 As shown, the system for converting multiple switching nodes into a single switching node of the present invention includes: a plurality of switching nodes providing signals, a parallel / serial transmission mode conversion device, a switching network...

Abstract

The related method for conversing multiple exchange nodes into the single exchange node comprises: conversing the resource signal of multiple exchange nodes into the signal for serial transmission mode, accessing same-type electric-level interface; connecting with the resource allocation module of EN to select the output from the allocation module output port. Thereby, the relative system comprises multiple exchange nodes, a transmission mode conversion device for parallel / series, and a resource allocation module to select special exchange node signal. This invention reduces design difficulty,and saves cost.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for converting multiple switching nodes into a single switching node. Background technique [0002] In order to meet people's increasing demands for information such as voice, data and multimedia, it is necessary to technically integrate the communication network and the storage network. [0003] Traditional voice communication is based on Time Division Multiplexing (TDM) technology, data is mainly based on Internet Protocol (Internet Protocol, IP) and Asynchronous Transfer Mode (Asynchronous Transfer Mode, ATM) technology, multimedia is mainly based on Fiber Channel ( Storage technologies such as Fiber Channel, FC) and iSCSI. In order to simplify the network, people hope to unify the three communication networks of TDM, IP and ATM into one network. In the early years, many people studied how to unify the TDM network and IP network into the ATM network. Low cost ha...
