The host computer system, the primary offload engine and the alternate offload engine are in data communication, the primary offload engine is configured to save predefined data packet communication protocol parameters to the host computer system during normal operation, the alternate offload engine is configured to retrieve the parameters from the host computer system if the primary offload engine fails. | 09-25-2008 |
20080304490 | Systems and computer program products for header suppression in a network that guarantees in order delivery of packets - A method and computer program product for providing RTP suppression across a DOCSIS network. An index number and a set of rules are sent to a receiver. The index number indicates the type of header suppression technique (i.e., RTP header suppression) to be performed, and the set of rules define how to recreate the RTP packets on the receiving end. At least one complete RTP packet is transmitted upstream for enabling a receiver to learn the RTP header. Subsequent RTP packets are transmitted upstream for reconstruction at the receiving end. The subsequent RTP packets are comprised of delta values representing fields that dynamically change from packet to packet in an RTP header. | 12-11-2008 |
20080310420 | Method and system for transparent TCP offload with transmit and receive coupling - Certain aspects of a method and system for transparent transmission control protocol (TCP) offload with transmit and receive coupling are disclosed. Aspects of a method may include collecting at least one received TCP segment for a determined network flow via a network interface card (NIC) processor. The state information for the received TCP segment and state information for transmitted TCP segments for the determined network flow may be stored at the NIC without transferring state information for the received TCP segment and the state information for the transmitted TCP segments to a host system communicatively coupled to the NIC. A new TCP segment comprising the collected TCP segments may be generated after a termination event occurs. The generated new TCP segment, new state information for the generated new TCP segment, and the state information for the transmitted TCP segments may be communicated to the host system for TCP offload. | 12-18-2008 |
20090034534 | SYSTEM AND METHOD FOR ESTABLISHING AND MANAGING MULTIMEDIA SESSIONS BETWEEN TERMINALS - A source communication terminal includes a communication module that initiates a first communication with a first remote terminal via first Internet protocol (IP) multimedia subsystems (IMS) of a first IP network. The first communication includes X media components. The source communication terminal also includes a media transfer module that transfers Y of the X media components to a first target terminal of Z target terminals during the first communication. The source communication terminal also includes a control module that provides an indication to the first IMS of a control model for the first communication. The control model is implemented after the Y media components have been transferred to the first target terminal. The control model identifies at least one of the source communication terminal and the first target terminal that controls IMS signalling for the first communication. X, Y and Z are integers greater than or equal to 1, and Y is less than or equal to X. | 02-05-2009 |

20090109978 | Application interface for global mobile message delivery - A device, system, and method are directed towards communicating mobile information over a network. A mobile message (MM) is generated by an Internet Protocol (IP) enabled application interface. The MM may include advertising information. The MM is received at a routing server and comprises a destination phone number and/or advertising information. If the MM is determined to be locally processed, the routing server selectively routes the MM to a destination carrier associated with the destination phone number. If the MM is determined to be remotely processed, the MM is recursively forwarded until the MM reaches another routing server associated with the destination phone number. The other routing server is configured to selectively route the MM to the destination carrier. A response MM may be received at a boundary routing server. The response MM may be sent to the API if at least a portion of the response MM matches information associated with the MM. | 04-30-2009 |
20100020808 | TECHNIQUES FOR INTEGRATED ROUTING OF CALL CIRCUIT SIGNALING AND THE INTERNET PROTOCOL - Techniques for processing an IP packet at a router that supports SS7 signaling include receiving IP routing data that associates a network link and a destination IP address for a node in a signaling network that includes a plurality of signaling nodes. When an ingress IP data packet is received, it is determined whether conditions are satisfied for locally processing an SS7 payload within the ingress IP data packet. If it is determined that conditions are satisfied for locally processing the SS7 payload, then the SS7 payload is processed locally, i.e., without sending the SS7 payload over a network link to a different node in the signaling network. If it is determined that conditions are not satisfied for locally processing the SS7 payload, then the ingress IP data packet is routed normally. These techniques allow reduced numbers of expensive STP devices and expanded routing options in a signaling network. | 01-28-2010 |
20100054259 | SYSTEMS AND METHODS FOR INTERWORKING OSIG AND H.323 SIGNALING IN A SIP-BASED NETWORK - A SIP-based network architecture is defined allowing a variety of access methods for interfacing QSIG-based signaling devices. The QSIG-based signaling devices are typically enterprise-based PBXs that either interface directly via QSIG, or adapt QSIG signaling to related signaling protocols via gateways, which can be customer premise or network based. The gateways can either interwork QSIG signaling or tunnel QSIG signaling over H.323, SIP, or other protocols. Upon reaching the SIP-based network, Session Border Controllers process the signaling. The Session Border Controllers terminate the tunnel (if used) and extracts the QSIG signaling for interworking to SIP, thereby facilitating a homogeneous SIP-based core network. In addition to interworking QSIG signaling, the Session Border Controllers perform other signaling related functions for the SIP-based network that are performed at a point as near as possible to the network's edge. | 03-04-2010 |

The virtual circuit transports ATM media for the session between the first and second devices. An intelligent control layer provides IP and ATM signaling to set up the session. | 07-14-2011 |
20110194563 | Hypervisor Level Distributed Load-Balancing - A method and an apparatus of hypervisor level distributed load-balancing are disclosed. In one aspect, a method includes determining a location to direct a packet. The method also includes distributing the packet to process the packet through a processor. The method also includes assigning the packet to a guest such that a distribution of the packet to the guest is based on an algorithm. The method further includes altering a first destination address of the packet to a second destination address. The second destination address may be based on a virtual network interface of the guest. The method further includes convincing the guest the packet is from a virtual switch based on the second destination address. In addition, the method includes adjusting the distribution of the packet to the guest. The method also includes reducing a load of the guest through the adjustment. | 08-11-2011 |
