ABSTRACT:
A quality of service (QoS) signaling packet for arranging QoS connections upon handoff between a mobile node (MN) and a correspondent node (CN) using Internet Protocol (IP), the signaling packet includes one or more QoS flow requirements, one or more classifier parameters, QoS session identification information composed of a previous QoS session ID, a new QoS session ID, and a sequence number. The QoS session IDs are used for establishing a new data path and for added security against spoofing, can be composed of a key-based signature combination of a mobile node's new care of address (CoA) and the sequence number. The packet may also include a previous node address and a cookie, both of which are inserted by a previous node. The previous router address is used for backtracking communications and establishing/updating flow tables while the cookie is used for authentification of node-to-node messages.
