IPV4/IPV6 routing capacity sharing method based on TCAM

Abstract

The invention relates to an IPV4/IPV6 routing capacity sharing method based on a TCAM and relates to the technology of TCAMs. The method includes the steps that a TCAM hardware table is divided into a front section area and a rear section area; a single IPV6 routing prefix is divided into an IPV6 front half part and an IPV6 rear half part; for IPV4 routing, matching of the front section area is carried out, and matching of the rear section area is carried out if matching of the front section area fails; for IPV6 routing, matching between the IPV6 front half part and the front section area is carried out firstly, and if matching between the PV6 front half part and the front section area succeeds, matching between the IPV6 rear half part and the rear section area is carried out continuously. By the IPV4/IPV6 routing capacity sharing method, items of the hardware table in IPV4 routing and IPV6 routing can be allocated dynamically and flexibly, it is unnecessary to make different software versions for two routers, the specification index of the routers is increased, and requirements of more routers are met.

AI Technical Summary

Benefits of technology

This technology improves how routers handle different types of data traffic by optimizing their use of network devices' memory space based on factors like available bandwidth or link speeds. It allows for flexible changes when adding new connections without affecting existing ones. Overall this results in improved performance and better overall functionality across multiple networks with varying capabilities.

Problems solved by technology

The technical problem addressed in this patents relates to improving the flexibility and efficiency of accommodating multiple types of connections on contemporary computer systems while maintaining compatibility between them. This requires more efficient ways to handle both new services like internet access or data transfer over wireless communication links without sacrificing performance levels due to limitations such as available bandwidths. Current methods require separate storage areas for each type of connection, making it difficult to manage complex configurations.
