Abstract

When moving between networks, the endpoint's IP address can change or, due to NAT, the endpoint's public IP address can change. Such a change of IP address breaks upper-layer protocols such as TCP and RTP. Various techniques exist to prevent this breakage, all tied to making the endpoint's IP address static (e.g., Mobile IP, Proxy Mobile IP, Locator/ID Separation Protocol (LISP)). Other techniques exist, which make the change in IP address agnostic to the upper- layer protocol (e.g., Stream Control Transmission Protocol (SCTP)). The mechanism described in this document is in that last category.

          Mobility with Traversal Using Relays around NAT (TURN)

Abstract

   It is desirable to minimize traffic disruption caused by changing IP    address during a mobility event.  One mechanism to minimize    disruption is to expose a shorter network path to the mobility event    so that only the local network elements are aware of the changed IP    address and the remote peer is unaware of the changed IP address.

   This document provides such an IP address mobility solution using    Traversal Using Relays around NAT (TURN).  This is achieved by    allowing a client to retain an allocation on the TURN server when the    IP address of the client changes.
