High-Performance Network Data-Packet Classification Using Embedded Content-Addressable Memory (TCAMs)

With port speeds exceeding 100Gbps, route lookups that are fundamental to all routers have relied on ternary content addressable memories (TCAMs) to provide a lookup response within a clock cycle. However, TCAMs in discrete form are expensive, consume a lot of power, compete for precious real estate on the printed circuit board (PCB), and in some applications lack required flexibility.
