Abstract:
1. A machine-implemented method for enabling communication between nodes, the method comprising the steps of: receiving a handshake phase initiation request that originated from a particular client node and was intercepted by a load-balancing node; and engaging in a handshake phase with the particular client node using IPv6 mobility features to allow communication with the particular client node without further intervention by the load-balancing node; wherein receiving the handshake phase initiation request comprises receiving, at a server node that is associated with a first Internet Protocol (IP) address, a first IP packet that contains a second IP packet that: wherein engaging in the handshake phase comprises sending, toward the particular client node that is associated with the third IP address, a third IP packet that: wherein the Binding Update option indicates, in a Lifetime field, a value that is greater than zero; wherein the presence of the value in the Lifetime field causes the client node to establish a cache entry comprising the first IP address and the second IP address locally within an IP layer cache; wherein the cache entry remains in the IP layer cache for a period of time commensurate with the value indicated in the Lifetime field; wherein the second IP address is a virtual IP address that is associated with a server cluster of a plurality of nodes that includes the server node.
