Other Applications of CAM
We see many in previous post, now we can see other applications of CAM.
1. MPLS switching at core and edge routers. MPLS switching involves label look up in place of an IP address look up. MPLS label consists of label value, QoS, stack flag and TTL (time to live). When a look up for such a data happens, the network processor can use the relevant information and decide the fate of the packet, i.e if the TTL has lapsed, it would drop the packet and so on.
2. Signature Recognition. With the performances and speeds (up to 10 Gbps) that current technologies are achieving in communication, the performance of the CAM is extremely important. One of the foremost applications that the internet needs is data protection. With new ways coming in vogue to hack an end point, the need for protection from such attacks, be it through a virus or a spam, is necessary. If such a process can be achieved in hardware, it improves the throughput drastically. CAMs can help in such a cause by maintaining a signature database and an associate processor (if it can be built to work at line speeds) can scan the packets for such signature and drop packets if necessary; such a functionality would add immense value to the content moved across the internet.
