Patent number: 8751865Abstract: A system and method are disclosed for the repair of IP multicast sessions. A repair server polls multiple transmit servers to accumulate as many of the packets missing from the multicast session as possible. A network includes a source of multicast packets in a multicast session and a plurality of multicast recipients in that session. A repair server in the network provides the packets it receives to the recipients. The repair server includes a missing packet detector. There is a plurality of retransmit servers in the network buffering portions of the packets they respectively receive during the session. The repair server maintains an ordered list of the retransmit servers that are most likely to have buffered copies of packets missing from the session. When the repair server detects that there are packets missing from the session it has received, it uses the ordered list to sequentially request the missing packets from respective ones of the plurality of retransmit servers.Type: GrantFiled: July 30, 2013Date of Patent: June 10, 2014Assignee: AT&T Intellectual Property II, L.P.Inventors: Nicholas Frank Maxemchuk, David McManamon, David Hilton Shur, Aleksandr Zelezniak

Method and system for a unicast endpoint client to access a multicast internet protocol (IP) session
Patent number: 7724744Abstract: Unicast endpoint clients on an IP Unicast network are provided access to Multicast sessions on an IP Multicast network through a Multicast-Unicast gateway server. The server obtains information about sessions on the Multicast network and makes such information available to a Unicast client on the Unicast network upon request by the client. Upon being presented with a list describing the subject matter of each session, the user at the Unicast client selects the session to which he or she wants to join, which causes the Multicast-Unicast server to join the appropriate session on behalf of the requesting client. All packets then received by the server from the Unicast client are address-translated to the appropriate Multicast session address and vice versa. The Unicast client is then able to participate in the Multicast session as both a sender and receiver of packets to and from other Unicast and Multicast clients which are active.Type: GrantFiled: October 25, 2005Date of Patent: May 25, 2010Assignee: AT&T Corp.Inventors: David Hilton Shur, Aleksandr Zelezniak -
