Content-Based Route Lookup Using CAMs

The applications of the Internet have evolved from being host-centric to being more content-oriented, such as file sharing, online audio and video applications, which constitute the majority of Internet traffic. Several future Internet architectures, putting the content (or information) in the forefront, have lately been proposed in order to solve the limitations of the current architecture (i.e. insufficient bandwidth to servers, lack of security, mobility, virtualization, user/data centricity, etc.). However, one of the greatest challenges of a novel content-oriented Internet architecture lies in the complexity of looking up long, variable length names compared to the current 32 bit long IPv4 (or even 128 bit IPv6) addresses of today's networks.
