Abstract

Using an auxiliary table in a data center switch, compression of addresses can be achieved and scalability obtained without increasing the size of expensive lookup tables. A prefix-based Internet Protocol (IP) address is stored in the lookup tables instead of the host route, and the auxiliary table is used to mask certain bits of the IP address. This solution increases the scalability of support of southbound hypervisors without adding to the cost of increasing the lookup table size in an application specific integrated circuit (ASIC) in a data center switch.
