Abstract
Representative implementations of devices and techniques provide care-of-address handover. In one implementation, a message is sent to a server in a point-to-point communication session. The message includes a care-of-address of a first network interface (e.g., wireless network interface) and a care-of-address of a second network interface (e.g., wireline network interface). The care-of-address of the first network interface is a current care-of-address being used in the communication session and the care-of-address of the second network interface is a new care-of-address that a device (e.g., a mobile node) is going to transition to (e.g., handover). The message may also include the server's IP address and TCP (Transfer Control Protocol) port. Furthermore, the message may include the mobile node's TCP port.
