DUOS - Simple dual TCAM architecture for routing tables with incremental update
Tania Mishra, Sartaj K. Sahni · 2010
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 that support incremental updates without delaying lookups, DUOS offers reduction in power consumption and improvement in average performance for update operations.
