TCP Handoff

Jump to: navigation, search

TCP handoff is a technique to handoff one TCP socket endpoint from one node to the other seamlessly, which is to migrate the established TCP state from the original node to the new node, so that the new node can send packets to the other TCP endpoint directly.

TCP handoff is mostly used to do content-aware request distribution among servers, which enables intelligent distribution to provide quality of service requirements for different types of contents and to improve overall cluster performance.
