Search process device and network system

Abstract

The invention provides a search process device and a network system, wherein the search process device comprises a first work mode and a second work mode; under the first work mode, a first request process unit parses a search request to obtain an IP address; a second request process unit obtains a matching index of the next skip list from the route table data according to the IP address; a first result process unit encapsulates the index of the next skip list to a data access request and send it through an interface unit; under the second work mode, the first request process unit parses the data access request to obtain the index of the next skip list; the second request process unit obtains the next skip information from the next skip list according to the index of the nest skip list; the first result process unit sends the next skip list information obtained by the second request process unit through the interface unit, so as to be perform route calculation by the network processor. The invention simplifies the route search process of the network processor, improves the system throughout rate and reduces the hardware cost and power consumption.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a search processing device and a network system. Background technique [0002] The Internet leads people into a new information age and plays a huge role in promoting the development of human society. [0003] The Internet is the carrier of information. In addition to the numerous terminal computers and data servers, what realizes the carrier function of the Internet is the network interconnection equipment that sets up this "information highway", such as routers or switches at all levels. The core function of the network interconnection device is to find the best transmission route for IP packets from different links and to different destinations in the routing table, and send the packets to the next hop in the same way. router, and so on, until the packet reaches its final destination. The algorithm of finding the best matching route in the routing table according to th...

Problems solved by technology

[0007] In the process of one IP packet forwarding calculation, the network processor needs to perform multiple request-feedback query processes with external devices (network search engine, external memory), and due to the difference in operating speed between the processor and the external memory, and the processor Access to external devices is affected by protocol delay, interface delay, queuing buffer, etc., which will cause a large system delay and affect data forwarding performance
