With rapid advancement in Internet technology and usages, some emerging applications in data communications and network security require matching of huge volume of data against large signature sets with thousands of strings in real time. In this article, we present a memory-efficient hardware implementation of the well-known Aho-Corasick (AC)(More)
 A multigigabit IP router may receive several millions packets per second from each input link. For each packet, the router needs to find the longest matching prefix in the forwarding table in order to determine the packet's next-hop. In this paper, we present an efficient hardware solution for the IP address lookup problem. We model the address lookup(More)
This letter presents a new oblivious routing algorithm for 3D mesh networks called randomized partially-minimal (RPM) routing that provably achieves optimal worst- case throughput for 3D meshes when the network radix fc is even and within a factor of 1/k<sup>2</sup> of optimal when k is odd. Although this optimality result has been achieved with the minimal(More)
With the continuous advances in optical communications technology, the link transmission speed of Internet backbone has been increasing rapidly. This in turn demands more powerful IP address lookup engine. In this paper, we propose a power-efficient parallel TCAM-based lookup engine with a distributed logical caching scheme for dynamic load-balancing. In(More)
Multi-field packet classification is necessary to support advanced Internet functions, such as network security, quality of service provisioning, traffic policing, virtual private networking, etc. Ternary content addressable memory (TCAM) is currently the dominant solution method used by the industry because of its speed and the simplicity of filter table(More)
Filter encoding can effectively enhance the efficiency of ternary content addressable memory (TCAM)-based packet classification. It can minimise the range expansion problem, reduce the TCAM space requirement and improve the lookup rate for IPv6. However, additional complexity will incur inevitably in the filter table update operations. Although the average(More)
