Abstract
A method for efficient communications with a cluster-based architecture preserves various aspects of integrity throughout one or more connections with a client, even in the midst of connection migration between nodes in the cluster. According to one aspect, the invention provides a mechanism for preventing the loss of packets arising from a TCP connection migration within the cluster. According to another aspect, the invention provides a mechanism for uniquely identifying conflicting TCP connections migrated to a common node. According to a still further aspect, the invention provides a distributed TCP timestamp mechanism so that the sender and receiver will have a consistent view of the timestamp even when each node has different local clock values and regardless of how many times the socket has been migrated.
