Network intrusion detection systems (NIDS) require multi-match packet classification, where all matching results need to be reported. Ternary Content Addressable Memory (TCAM) is well suited for high-speed packet classification problem by fast parallel matching. However, TCAM can only report first result due to the priority encoder structure. An efficient multi-match scheme is introduced in this paper...
Packet classification has been critical data path function for supporting quality of service (QoS), resource reservation protocol (RSVP) and broad range of multimedia services. Hardware based solution is necessary to keep up with high-speed rate up to OC192 processing. However, the range match in multi-fields classification is still one of the bottleneck problems. In this paper, a novel structure...
With sharp development of new application on network, bandwidth has increased up to 10~40 Gbps. It??s very important to take more efficient information processing to fulfill requirements of better services quality. This article focuses on the construction of backbone network based on IP over SDH. By analysis of transmit structure and protocol stack, several key techniques of information processing...
