20090168787 | Method and Apparatus for Rapid Session Routing - A gateway device at a user premises edge of a wide area network implements a method for rapidly routing a media session. for an application layer service. The gateway device receivers a request from a first endpoint device to create the media session with a second device. The request includes an application layer identifier for the second device. The method involves accessing a routing table within the gateway device using the application layer identifier and obtaining, from the internal routing table a network layer address for communication with the second device.

A public address is assigned to the access terminal having a local address assigned by the first or second access router. At the access gateway, source addresses of packets sent from an access terminal to a remote correspondent node are translated by replacing the local address of the access terminal with the public address of the access terminal. The access terminal continuously maintain a communication session with the correspondent node as the access terminal moves from a first location to a second location and switches from accessing the first access router to accessing the second access router.

20090168792 | Method and Apparatus for Data Traffic Smoothing - A method and device for data traffic smoothing are provided. Arriving data packets are buffer-stored and passed on by taking account of an overhead of management information which is attached to the data packet in a protocol conversion process, which is carried out later.

The data transmission rate measured from the point of view of the network element carrying out the data traffic smoothing is not the criterion to be adjusted, but the data transmission rate after protocol conversion. A quality of service both for low and high data packet lengths is ensured, and the bandwidth of a DSL connection can therefore be exploited fully both for the VOIP and for data transmission. | 2009-07-02 |

20090168799 | Network Acceleration Techniques - Splintered offloading techniques with receive batch processing are described for network acceleration. Such techniques offload specific functionality to a NIC while maintaining the bulk of the protocol processing in the host operating system (“OS”). The resulting protocol implementation allows the application to bypass the protocol processing of the received data. Such can be accomplished this by moving data from the NIC directly to the application through direct memory access (“DMA”) and batch processing the receive headers in the host OS when the host OS is interrupted to perform other work. Batch processing receive headers allows the data path to be separated from the control path. Unlike operating system bypass, however, the operating system still fully manages the network resource and has relevant feedback about traffic and flows. Embodiments of the present disclosure can therefore address the challenges of networks with extreme bandwidth delay products (BWDP). | 2009-07-02 |

Polling may respond to a “poll-me bit,” and/or it may be adaptively periodic at a rate based on communication status parameters, such as recent communication activity and connection QoS levels. Group polling permits a possibility of collisions. Polling policies may be established for dynamically varying user groups, or may be determined for each user. Dynamic selection of appropriate polling techniques makes use of efficiency benefits associated with each technique. | 2009-07-02 |
