摘要： A transport scheme is provided based on Internet protocol (IP) and multiprotocol label switching (MPLS) technology for third generation (3G) radio access networks (RAN). Label switched paths are established and managed for interconnecting base stations and radio network controllers. The process incorporates constraint-based routing and Diffserv to provide transport bearers that can support bandwidth provisioning and a variety of QoS requirements in the RAN.

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 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： 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 from 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 data structure for preventing the misconcatenation of partial packets when an even number of packets are lost over the network. A channel identifier code is added to the head of a remainder partial packet to allow the remainder partial packet to reassembled with a prior partial packet having the same channel identifier code. The method includes the steps of determining whether each packet will be divided into a first partial packet and a remainder partial packet at an ATM cell boundary, adding a CID at the beginning of each remainder partial packet, assembling the first and remainder partial packets into ATM cells, transmitting the ATM cells, receiving the ATM cells, verifying whether a first partial packet and a remainder partial packet in the received ATM cells have the same CID and assembling the first partial packet and the remainder partial packet into a single packet when the CIDs match. The method may also includes the steps of discarding the first and remainder partial packets when the CIDs do not match or sending the first partial packet to a user identified by the CID for the first partial packet and the remainder partial packet to a user identified by the CID for the remainder partial packet. The CID comprises a one byte code. The data structure for the ATM cell includes a header and a payload assembled to the header, the payload comprising at least one packet, wherein the at least one packet comprises a remainder partial packet having a channel identifier code attached thereto to identify the user for the remainder partial packet.
