DUOS - Simple dual TCAM architecture for routing tables with incremental update

We propose a dual TCAM architecture - DUOS, for routing tables. Four memory management schemes for TCAMs also are proposed and evaluated. DUOS and our memory management schemes support control-plane incremental updates without delaying data-plane lookups. Compared to other TCAM architectures such as CAO OPT [19] that support incremental updates without delaying lookups, DUOS offers reduction in power consumption and improvement in average performance for update operations.
