Market Enticing for New Entrants Despite NetLogic's Dominance
"Search coprocessors are used in routers, switches, and network
appliances to classify data, apply security policies, and determine
where to send each packet. A search coprocessor can be developed
using algorithms and memory, TCAMs (ternary content addressable
memory), or a combination of the two. Cisco was the first major
OEM to adopt merchant search coprocessors. Since then,
search-coprocessor functions have evolved from TCAMs to become
hybrid devices that support both TCAM lookups and algorithmic
"Through innovation and smart business decisions, NetLogic has
established itself as the dominant supplier of search coprocessors.
The company's only competitor is Renesas, which is a distant second
and has few shipments outside of Cisco. NetLogic's NLA10k/11k search
coprocessors are capable of supporting up to 512K IPv4 entries using
its KBP (knowledge-based processor) engines and a larger set of
entries using its Sahasra algorithmic search engine."
"In the last five years, the market for search coprocessors has
grown from around $200 million to around $300 million. This
growth was fueled by 10Gbps port rates, greater-capacity line
cards, and policy-based routing, which requires multiple lookups
per packet. Carrier Ethernet is a recent driver of new growth in
