Patent number: 11184240Abstract: Systems, methods, and instrumentalities are disclosed to communicate with subscribers in an information-centric networking environment. A WTRU may store a first path from the WTRU to a first subscriber and a second path from the WTRU to a second subscriber. A message from a topology manager may be received. The message may indicate a change to a network topology. In response to a determination that the change to the network topology relates to the first path and does not relate to the second path, the WTRU may remove the first path from the memory and maintain the second path in the memory. The WTRU may send a request to the topology manager for a third path to replace the first path that was removed from memory. In response to the above determination, a portion of the first path may be removed and replaced according to the above mechanism.Type: GrantFiled: July 8, 2016Date of Patent: November 23, 2021Assignee: IDAC Holdings, Inc.Inventor: Dirk Trossen
