Load balanced self-routing data exchange structure and method

Abstract

The invention provides a load balanced self-routing data exchange structure. The structure is characterized by comprising a load balanced self-routing processing unit and non-blocking exchange unit; the load-balanced self-routing processing unit realizes an operation of sending a data packet at an entrance port to a switch entrance caching module of the non-blocking exchange unit through the routing address information processing of a to-be-forwarded data packet, non-blocking exchange unit entrance traffic monitoring, the load balancing operation and to-be-forwarded data packet branch transmission. Under the condition of unchanging the final data exchange destination port, the path free selection can be performed according to a data forwarding path and a reachable forwarding path resource,namely self-routing; the data congestion probability and the packet loss probability are reduced, and the data exchange real-time performance is enhanced.

Description

technical field [0001] The invention belongs to the field of data exchange structures, and in particular relates to a load balancing self-routing data exchange structure and method. Background technique [0002] In the data communication industry, the core content of the data exchange chip is the exchange structure. The main function of the exchange structure is to complete the transmission of data packets / data packets between different ports. The transmission process is usually described as data exchange, the unit that realizes the data exchange function The structure is the switching structure. The mainstream switching structures include Crossbar structure, Central buffer structure, IQOQ structure, CIOQ structure, Noc structure and so on. [0003] In the above-mentioned mainstream switching structure, the data forwarding path is usually fixed, and there will be disadvantages such as data packet blocking and buffering on the data forwarding path that increase the delay of d...

Problems solved by technology

[0003] In the above-mentioned mainstream switching structure, the data forwarding path is usually fixed, and there will be disadvantages such as packet blocking and buffering on the data forwarding path, which increase the delay of data forwarding.

At the same time, congestion on the data forwarding path will cause data overflow or packet loss after the data buffer is full, and the real-time nature of data forwarding will further reduce the impact
