Abstract
Not Mobile IP (NMIP) comprises methods for implementing macro-mobility in an IP network, wherein macro-mobility means the ability of a node to change its network-layer, e.g., IP, address without disturbing existing transport-layer and application-layer sessions, e.g., conversations. When two NMIP nodes establish a new NMIP session, they exchange pseudo-random numbers, or nonces, and store the nonces in a session table. When a first node changes its IP address, the first node sends to the second node an address-update message that contains the new IP address and the first node's nonce. If the received nonce matches a nonce in the session table, then the second node updates its protocol control blocks with the new IP address, and sends an address-update reply message to the first node. Internet Protocol Security (IPsec) can be used to secure or replace the exchange of nonces.
