Publication number: 20160164780Abstract: A packet routing method for directing packets of a session in an IP network causes an intermediate node to obtain a lead packet of a plurality of packets in a given session. The intermediate node has an electronic interface in communication with the IP network and obtains the lead packet through that same interface. The method maintains, in a routing database, state information relating to a plurality of sessions in the IP network. Each session includes a single stateful session path formed by an ordered plurality of nodes in the IP network, and the state information includes information about the ordered plurality of nodes in the sessions. The method further accesses the routing database to determine the state of a plurality of sessions, and forms a stateful given path for packets of the given session across the IP network as a function of the state information in the routing database.Type: ApplicationFiled: December 8, 2014Publication date: June 9, 2016Inventors: Patrick Timmons, Michael Baj, Hadriel Kaplan, Patrick MeLampy, Prashant Kumar, Robert Penfield

Patent number: 7822433Abstract: A communications system having a pre-defined calling group with a plurality of members is disclosed. A plurality of personal communication devices (PCDs) each have a system ID and a group ID, and each member of the group is assigned one of the PCDs. The system ID and the group ID both have a predetermined characteristic, where each system ID has a first variation thereof and each group ID has a second variation. A first group-member having a first PCD contacts a second member having a second PCD by entering into the first PCD the second PCD group ID. The first PCD transmits the first PCD system ID and the second PCD group ID to a communications switch. Based on the first PCD system ID, the communications switch locates a record for the first PCD in a switch database and determines therefrom that the first PCD can contact the second PCD by way of the second PCD group ID. A group database in switchable communication with the communications switch has the system ID and group ID for each group member PCD.Type: GrantFiled: January 23, 2007Date of Patent: October 26, 2010Assignee: AT&T Intellectual Property I, L.P.Inventors: Karen Tirabassi, Andrew Goldberg, Greg Butz, Patrick Melampy, Mary Stanhope, Andrew Coppola

Publication number: 20070116043Abstract: Methods and systems for processing a signaling message are disclosed. An exemplary method comprises: determining a first transcoding policy associated with an originator endpoint contained in a received first call offer; determining a second transcoding policy associated with an answerer endpoint contained in the first call offer; applying the first transcoding policy to a first offer codec set in the first call offer to produce a second call offer containing a second offer codec set; applying the second transcoding policy to the second codec set to produce a third call offer containing a third offer codec set; comparing a first answerer codec set in a received first answer and a second answerer codec set contained in the second call offer; and determining whether or not to perform transcoding based on a result of the comparison.Type: ApplicationFiled: September 15, 2006Publication date: May 24, 2007Inventors: Patrick MeLampy, Robert Penfield, Clifford Spencer, David Gray

Publication number: 20070104105Abstract: Systems and methods for determining lost packets for real-time transport protocol (RTP) data flows is disclosed. Generally, a first endpoint is connected to a second endpoint, wherein the first endpoint comprises a transceiver, software stored within the first endpoint defining functions to be performed by the first endpoint, and a processor. The processor is configured by the software to perform the steps of determining a sequence number of a received RTP data packet within said RTP data flow, storing said determined sequence number, calculating whether said determined sequence number sequentially falls within a predetermined numerical order, and if said sequence number of said received RTP data packet does not sequentially fall within said numerical order, storing said sequence number as a missed RTP data packet.Type: ApplicationFiled: December 27, 2006Publication date: May 10, 2007Inventors: Patrick MeLampy, Ephraim Dobbins, Stephen Norton, Robert Penfield

Publication number: 20070076603Abstract: A system and method for providing session admission control are provided. Generally, a source of a communication request and a session director are utilized. The session director allocates bandwidth to accommodate a bandwidth allocation request from the source, ensures that quantity of the allocated bandwidth is appropriate for transmission of multimedia packets from the source to the session director, and ensures that quality of service of the allocated bandwidth is appropriate to provide a flow of the multimedia packets via the allocated bandwidth.Type: ApplicationFiled: November 17, 2006Publication date: April 5, 2007Inventors: Patrick MeLampy, Robert Penfield, Kevin Klett

Publication number: 20070076855Abstract: Systems and methods for partitioning session initial protocol (SIP) processing among execution units are disclosed. An exemplary device comprises: a plurality of execution units and a plurality of session initiation protocol (SIP) processes. The SIP processes comprise: a SIP transport process; a SIP location server process; and a plurality of SIP core processes. The SIP transport process executes on a first one of the execution units. The SIP location server executes on a second one of the execution units. Each of the SIP core processes executes on a different remaining one of the execution units. An exemplary method comprises: executing a SIP transport process on a first one of the execution units; executing a SIP location server on a second one of the execution units, and executing each of the SIP core processes on a different remaining one of the execution units.Type: ApplicationFiled: September 15, 2006Publication date: April 5, 2007Inventors: Patrick MeLampy, Robert Penfield

The system ID and the group ID both have a predetermined characteristic, where each system ID has a first variation thereof and each group ID has a second variation. A first group member having a first PCD contacts a second member having a second PCD by entering into the first PCD the second PCD group ID. The first PCD transmits the first PCD system ID and the second PCD group ID to a communications switch. Based on the first PCD system ID, the communications switch locates a record for the first PCD in a switch database and determines therefrom that the first PCD can contact the second PCD by way of the second PCD group ID.

Publication number: 20060285493Abstract: Methods and systems for controlling access to a host processor is disclosed. One exemplary method comprises the steps of receiving a plurality of signaling packets and controlling access to a host processor, via a first and a second path, for at least a portion of the packets in accordance with a bandwidth limit for the respective path. An exemplary system comprises: a host processor; and a traffic manager coupled to the host processor via a first path and a second path. The traffic manager is configured to communicate at least a portion of the packets to the host processor via a selected one of the paths. The traffic manager is further configured to regulate traffic along the first path such that the bandwidth limit of the first path is respected, and to regulate traffic along the second path such that the bandwidth limit of the second path is respected.Type: ApplicationFiled: June 16, 2005Publication date: December 21, 2006Inventors: Ajay Manuja, Patrick MeLampy, Ephraim Dobbins, Robert Penfield
