Packet classification is a fundamental enabling function for various applications in switches, routers and firewalls. Due to their performance and scalability limitations, current packet classification solutions are insufficient in ad-dressing the challenges from the growing network bandwidth and the increasing number of new applications. This paper presents a scalable parallel architecture, named...
This letter addresses the scalability problems induced by high complexity of multicast scheduling algorithms in high-speed switches. Based on a two-phase (request-grant) scheduling scheme in a Nx N switch, a more scalable approach instead of traditional iterative schedulings is presented, which reduces the matching overhead from O(kN) to O(N) by selecting one head-of-line cell for requesting when...
