Abstract
This paper addresses the problem of efficient filter updates in TCAMs. Under realistic conditions, filter updates can lead to significant performance degradation. This paper introduces an approach to using TCAMs that encodes filter priority as a TCAM field, allowing the highest priority filter to be identified with a small number of lookups, while greatly simplifying filter set management, and reducing the impact of updates on lookup throughput. Our approach supports wire-speed processing for OC-192 links using commercially available TCAM components.
