Abstract

The invention discloses a system for controlling multi-user parallel operation of a TCAM, and a control method thereof. The system comprises a FIFO unit, a TCAM user arbitration unit, a TCAM timing control unit, a TCAM interface, an initialization configuration unit, a query result arbitration unit and a statistics unit. According to the invention, the following advantages are achieved: good compatibilities with TCAMs from different manufacturers are achieved while operating speeds of the TCAMs is improved, and corresponding products can be developed to quick response to market demands.

Description

technical field [0001] The invention relates to a control system and a control method for multi-user parallel operation of TCAM. Background technique [0002] With the development of the Internet, the business of the Internet tends to be diversified, complex and personalized. At the same time, the bandwidth is getting bigger and bigger. At present, 1G / 10G and even 40G / 100G are commercially available on the market. It will inevitably have an impact on some fields, especially the fields of network information security, network information monitoring and network information management, mainly because the CPU handles more and more things, and the increase in speed cannot meet the requirements. [0003] In view of the current situation, a completely hardware-based network service flow query system is emerging quietly. Among them, when a ternary content addressable memory (TCAM) needs to be used for service query, the operation on the TCAM is very complicated or not universal. ...
