CYNSE20512

The high-speed Ayama 20000 family,CYNSE20512 of NSEs can be deployed in a variety of networking and communications applications. The performance and features of the  CYNSE20512 make it attractive in applications such as enterprise LAN switches, routing equipment, and security applications. The Ayama 20000 family of high-speed search engines are capable of supporting network data rates in excess of 10 Gbps.

The Ayama 20000 network search engine (NSE),CYNSE20512 provides a seamless connection to commercial packet processors via the industry-standard Look Aside (LA-1) Interface. The Ayama 20000 consists of control logic, which processes the commands, and a full Ternary Content-Addressable Memory (TCAM) array, which stores the databases searched by the control logic. Figure 1 shows a block diagram of the Ayama 20000. The Ayama 20000 family includes densities of 18-Mbit (512k entries) and 9-Mbit (256k entries).

Using its two LA-1 ports, the Ayama 20000 NSE ,CYNSE20512 can interface with one or two packet processors. The processor issues commands and the Ayama 20000 returns the results of execution via this interface. One port may be connected to an ingress packet processor and the other to an egress packet processor. Both packet processors can perform searches on the same databases, eliminating the need for redundant memories or NSEs.

This family ,CYNSE20512 is designed to be scalable to support large databases. Through the FastLink Interface, the Ayama 20000 can access both the Ayama 10000 and the Sahasra 50000 NSEs.
