Abstract
A method to provide load balancing and routing for a plurality of end systems in a network. The network contains a load balancer (LB) and the method comprises receiving a request packet with Internet Protocol version 6 (IPv6) addresses specified. A destination address is associated with a set of target end systems and presence of a nonce information indicates the requesting correspondent node is Identifier Locator Network Protocol (ILNP) capable. The method further comprises directing the request packet to a specific end system from the set of target end systems that share a load balanced address, wherein each target end system has a unique direct path locator prefix. The method also comprises overwriting a common IPv6 locator prefix with the unique direct path locator prefix, forwarding the request packet to the specific end system, and notifying a requesting correspondent node the direct path locator prefix for the specific end system.
