Abstract
A system and an article of manufacture for enabling co-existence of multiple machines with identical addresses within a single data center network. include assigning a unique pseudo identifier to each machine in the network that can be used for routing a packet to a destination machine, replacing a sender media access control address on an address resolution protocol request with a pseudo identifier of the sender at an edge network switch, retrieving a private network identifier from a mapping table based on the sender pseudo identifier and returning a pseudo identifier for the destination address based on the private network identifier, and replacing the pseudo identifier of the destination address with an actual identifier at a destination edge network switch for routing the packet to the destination machine.
