摘要： The present invention supports a protection path in a radio access network in order to continue communication between terminating nodes of the radio access network if a failure occurs with a communications path between the terminating nodes. A node may assume the functionality of a router, a base transceiver station, or a base station gateway. The establishment of the protection path utilizes the redundancy of connectivity (255, 257, 259) in the radio access network when routing the protection path in accordance with a service protection model. The protection path may be configured with a service protection model that is based on a quality of service model or on a separate protection model. With a quality of service being associated with a traffic class, the service profile indicates the quality of service for different types of services for a user as well as the quality of service that is provided by the protection path if a failure occurs with the communications path.

摘要： A system and method are provided for requesting a resource over at least one network. The system includes a terminal, a host and a network proxy. The terminal can send a first request for the resource over a first network and a second network. In turn, the host can receive the first request and send a first response, where the first request identifies the resource at a first location on the host. The network proxy, which can communicate with the host over the second network independent of the first network, can receive the first response from the host, and reformulate the first request into a second request that identifies the resource at a second location. The network proxy can send the second request to a host of the resource at the second location such that the host of the resource at the second location can respond to the second request.

摘要： A novel approach is provided for avoiding the "slow-start restart" in TCP communications when network conditions dictate such. The disclosed approach serves to overcome the latency related to the "slow-start restart" by assessing network conditions and avoiding the "slow-start restart" when network conditions justify the avoidance. The disclosed methods, applications and devices implement the periodic communication of a probe packet that is generated and transmitted from a TCP sender to a TCP receiver during the period that the TCP network connection remains idle. Receipt of the probe packet by the TCP receiver will trigger transmission of an acknowledgment message by the TCP receiver. Upon receipt of the acknowledgement message the TCP sender will restart measurement of the idleness period and, as such the "slow-start restart" is avoided.

摘要： Method and apparatus for efficient management and transport of traffic over a network. The available bandwidth capacity of paths in a network may be stored in a first router. A request may be received at the first router from a network node of a second network for a signaled path through the network to a destination node. Paths may be examined by the first router and the signaled path assigned to a path for the first router to the destination node using an existing path through the network. Further, all traffic from a subnet to a given destination network may be handled by one or more mobile agents at the subnet. One or more mobile agents may be assigned to all or some of the traffic based on current path loading.

摘要： A method and apparatus for coupling IP ECN with ATM congestion control is disclosed. The invention extends IP-ECN to ATM devices with minimal implementation complexity. Thus, the performance of IP data traffic over ATM is enhanced without requiring packet-reconstruction at the ATM layer. The method includes using AAL5 packet trailers in ATM cells to detect packet boundaries for identifying a first cell in an IP packet, determining whether an ATM cell capable of using explicit congestion notification to indicate congestion and setting an explicit congestion notification indicator in a capable ATM cell to indicated a congestion to a source node. The use of the packet trailers further comprises monitoring a flag for indicating whether an ATM cell is an end of packet. The method further includes resetting the end of packet flag to an off state so the next cell is recognized as a first cell of a packet and transmitting the ATM cell (880). A determination is made as to whether the next ATM cell is a first ATM cell for a packet. The next ATM cell is transmitted when the ATM cell is not a first ATM cell for a packet. A determination is then made as to whether ATM congestion is associated with the next ATM cell. The next ATM cell is then transmitted when congestion is not associated with the next ATM cell.
