Abstract:
1. A method for managing a multicast tree using a multicast tree manager, the multicast tree adapted for conveying multicast content toward at least one user device via a network comprising a plurality of network elements, the method comprising: receiving, by said multicast tree manager, a request to modify said multicast tree, wherein said request is associated with a user device, wherein said request is received from a content server, wherein said content server is configured to provide multicast content for distribution over said multicast tree, wherein said multicast tree is configured to convey said multicast content toward said at least one user device; determining, by said multicast tree manager, at least one multicast tree change for modifying said multicast tree in a manner enabling seamless distribution of said multicast content toward said at least one user device in response to a movement of said at least one user device from a first network to a second network; and generating, by said multicast tree manager, at least one message for implementing said at least one multicast tree change within said network, said at least one message comprising information for modifying at least one routing table of at least one of said network elements based on said at least one multicast tree change.
