Ternary content-addressable memory (TCAM) is a popular hardware device for fast routing lookup. Though useful, TCAM arrays have high power consumption and heat dissipation, problems alleviated by reducing the number of routing-table entries. The authors present an approach that exploits two properties of prefixes to compact the routing table.
