  • Forwarding internet protocol version 6 link-local multicast to support roaming of wireless mobile client devices
    Patent number: 8848609
    Abstract: Techniques are provided for a foreign controller to receive a handoff message including information for a multicast group that is used to forward network control information originating from an Internet Protocol version 6 (IPv6) network router by a home wireless controller to one or more foreign wireless controllers for mobile client devices that were first associated with the home controller. The foreign controller joins a multicast group based on the information contained in the handoff message and establishes a communication path with a mobile client device. The foreign controller extracts network control information addressed to the mobile client device received from the home wireless controller via a multicast stream associated with the multicast group, and forwards the network control information to the mobile client device via the communication path.
