Communication system and method for processing communication service

Abstract

The invention relates to a communication system and a communication business processing method. The system comprises at least a communication module, each which includes a data processing unit, at least two business interface units and connecting unit connects the data processing unit and the business interface unit. The data processing unit provides at least two data interfaces, which are connected with the business interface unit respectively via the connecting unit and access to data processing unit, wherein the business from the business interface unit are processed. When one or more business interface units are pulled out, the data processing unit can also provide remaining tasks to avoid the idleness of the data processing unit; at the same, a plurality of business interface units support multiple business to make one data processing unit support multiple business (mixed service); meanwhile, the processing capacity of data business is enlarged or reduced by increasing or decreasing the number of business interface units.

Description

technical field [0001] The invention relates to the field of data communication, more specifically, to a communication system and method in which a plurality of service interface units can share one data processing unit. Background technique [0002] The data processing part of data communication equipment and other similar equipment usually adopts the form of a data processing card (board) and a service interface card (board) to process data services. The business interface card is usually composed of modules such as Framer (framer), PHY (physical layer device) or LanSwitch (Ethernet switching chip) to complete the sending and receiving of physical layer data; the data processing card is generally composed of NP (network processor, network processor) ) or a forwarding ASIC (Application Specific Integrated Circuit) and a traffic manager to complete the forwarding and traffic shaping of uplink and downlink messages. [0003] In an existing data communication device, a data c...

AI Technical Summary

Problems solved by technology

[0004] 1. The service interface card does not support hot swap: the service interface card is fixed on the data processing card. If the service interface card needs to be replaced, the service interface card must be pulled out together with the data processing card;

[0005] 2. The service type of the service interface card is single. Since there is only one service interface card, the entire service processing is single and cannot support mixed services;

[0006] 3. It is impossible to increase / decrease the business processing capacity by increasing / decreasing the number of service interface cards

[0008] 1. Once the service interface card is pulled out, damaged or unable to work normally, the data processing card will be idle;

[0009] 2. A service interface card only supports a specific service, while a data processing card is only connected to one service interface card, so it can only support a single service, but cannot support mixed services;

[0010] 3. It is impossible to increase / decrease the business processing capacity by increasing / decreasing the number of interface cards
