摘要： A technique for routing data frames in a telecommunications backhaul network (100) is provided. The telecommunication backhaul network (100) includes a plurality of points and links between the points so that at least two different routes for communicating data frames between a pair of end points is provided. A first end point (102) routes data frames that belong to a communication tunnel between the first end point and second end point (104) on a first route (106), which includes one or more intermediate points (100). At least some of the data frames include a continuity check message. The first end point reroutes data frames belonging to the communication tunnel to a second route that is different from the first route (106), if certain data frames including the continuity check message are lost in the network (100). As to a method aspect of the technique, at least one of the links of the first route are switched to a reduced link capacity. At least a portion of the data frames including the continuity check message are dropped in response to the reduction in link capacity by at least one of the intermediate points (110) of the first route (106).

摘要： A method and apparatus for packet scheduling over a communication link in a communication network. A data packet scheduler accords scheduling weights to at least two sets of data packets to be transmitted, and the sending of the sets of data packets is scheduled in accordance with the scheduling weights. When it is determined that a change in available bandwidth over the communication link has occurred, the scheduler dynamically adjusts the scheduling weight for each set of data packets on the basis of the available bandwidth. This ensures more efficient resource sharing control and resource guarantees when the available bandwidth changes.

摘要： A technique for routing one or more service tunnels in a telecommunications backhaul network (110) is provided. The telecommunications backhaul network has a first routing path (132) and a second routing path (134). As to a method aspect of the technique, data of the one or more service tunnels is transmitted on the first routing path (132). A reduction in transmission capacity is detected on the first routing path (134) by means of a first routing path condition. The first routing path condition indicates a state of the first routing path (132). A second routing path condition is determined indicating a state of the second routing path (134) in response to the detected reduction in transmission capacity on the first routing path (132). It is decided upon rerouting one or more of the service tunnels from the first routing path (132) to the second routing path (132) based on both the first routing path condition and the second routing path condition.

摘要： A method is presented of transporting data packets over a telecommunications transport network. The data packets are carried by a plurality of bearers. For each of the bearers, independently of the other bearers, bandwidth profiling is applied to the data packets of the bearer to designate as ‘green’ data packets that are conformant with a predetermined maximum Information Rate for the bearer. One or more data packets is buffered for up to a predetermined maximum ‘green’ buffer time, during which if transporting the data packet would not cause the maximum information rate of the bearer to be exceeded, the data packet is designated as a ‘green’ data packet. The data packets are forwarded for transporting over the transport network. If there is insufficient bandwidth available in the transport network to transport all data packets, data packets that are not designated as ‘green’ data packets are discarded, so as not to be transported through the transport network.

摘要： A method is provided of transporting data packets over a telecommunications transport network. The data packets are carried by a plurality of bearers, the bearers each carrying data packets that relate to different ones of a plurality of services. In the method, for each bearer independently of the other bearers, bandwidth profiling is applied to the data packets of the bearer to identify and mark the data packets of each of the bearers that are conformant with a determined maximum information rate for the bearer. The data packets are forwarded for transport through the transport network. If there is insufficient bandwidth available in the transport network to transport all data packets, data packets not identified by the profiling as being conformant are discarded, so as not to be transported through the transport network. The data packets of the bearer transported through the transport network are monitored to determine whether there has been any loss of data packets that should have been transported through the transport network, indicating congestion in the transport network. The maximum information rate of the bearer is adjusted based on the monitoring.

摘要： A method of prioritising packets for delivery over a transport network interconnecting nodes of a mobile network, where a guaranteed minimum information rate over the transport network is specified for the mobile network. The method comprises, for each bearer to be injected into the transport network from the mobile network, specifying a bearer information rate and marking packets up to that rate as conformant with the bearer information rate and marking packets exceeding that rate as non-conformant with the bearer information rate. A plurality of traffic type streams from the mobile network are converged, each traffic type stream comprising a plurality of bearers. Packets of the converged traffic type streams are inspected to identify packets marked as conformant and non-conformant, and re-marking non-conformant packets, or at least a fraction of non-conformant packets, as conformant if the converged rate of conformant packets is less than said minimum information rate. The transport network prioritises the delivery of packets marked as conformant over those packets marked as non-conformant.

摘要： A method for determining the capacity that is needed on an lub link to fulfill Grade of Service (GoS) requirements in a Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (UTRAN) for both Dedicated Channel (DCH) traffic and High-Speed Downlink Packet Access (HSDPA) traffic. The method includes determining the bandwidth demand of the HSDPA traffic (ElasticDim); calculating an average bandwidth of the DCH traffic on the lub interface (BW use,avg); setting an initial capacity (Capacity) to the capacity need of the DCH traffic (Capacity DCH), wherein at least the initial capacity will be provided for the DCH traffic in the dimensioned system; and, increasing the value of Capacity until a quality requirement of the HSDPA traffic is fulfilled, the maximum value of Capacity reached being the capacity that is needed for DCH and HSDPA traffic for the lub interface.

摘要： A method is described to be implemented by a node in a network. The method is for selecting an endpoint for a maximally redundant tree-fast reroute (MRT-FRR) detour path to optimize detour path cost or length across the network. The method defines a set of steps including selecting a destination node and next hop failure to calculate detour paths. A clean set of nodes for the network is then calculated, where the clean set of nodes are nodes in the network that are not impacted in reaching the destination node by the failure in the given next hop. A candidate node for the endpoint of the detour p path is selected from the set of clean nodes based on any one of a plurality of configured options and forwarding of data packets is configured to the selected candidate as the endpoint of the detour path to the destination node.
