... When TMSP is used, a message transmitted from CN to MN follows the conventional IP routing for both TCP and UDP packets. When MIPv6 is used, a message transmitted from CN to MN is first sent to the MN’s HA where the message is tunneled to MN. Likewise, a message from MN to CN is reverse tunneled ...
