Methods and apparatus for communicating with groups of devices sharing an attribute

摘要

Methods and apparatus for IPv6 based multicast are disclosed. An example method includes broadcasting a multicast group address advertisement instructing a recipient device to join an Internet Protocol multicast group, the Internet Protocol multicast group being associated with a physical attribute of the recipient device; and broadcasting a multicast message to the multicast address instructing the members of the multicast group to perform an action.

1. A method of joining a multicast group, the method comprising:
accessing an Internet message, the Internet message using an Internet Protocol version 6 protocol and identifying a first multicast group at a device, the first multicast group being associated with an attribute; determining, at the device, if the attribute associated with the first multicast group corresponds to a matching attribute of the device; joining the multicast group if the attribute associated with the first multicast group corresponds to the matching attribute of the device, wherein the device becomes a member of the first multicast group and remains a member of a second multicast group, the second multicast group being associated with a prior geographic location of the device; providing, to a service provider, a first list of multicast group memberships identifying group memberships of the device existing at a first time; transmitting a request to access a service provided by the service provider, the request including a second list of multicast group memberships identifying group memberships of the device existing at a second time after the first time, the second list to facilitate verification of an identity of the device to the service provider; and receiving access to the service in response to the device being identified based on the second list of multicast group memberships.
