Forwarding lookup in the open flow switch can be done for each arriving packet by every switch in path. Every switch maintains a set of IP prefix value in its lookup table. For a given IP address it finds a longest prefix match in the forwarding table that matches first fewer bits of destination address. Earlier, there are several technique that has been proposed to optimize the table space and to reduce the number of entries in the forwarding table. In TCAM prefix values needs to be stored in… CONTINUE READING
