    • 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).
    • 提供了一种用于在电信回程网络(100)中路由数据帧的技术。 电信回程网络(100)包括点之间的多个点和链路,使得提供用于在一对端点之间传送数据帧的至少两个不同路由。 第一终点(102)在包括一个或多个中间点(100)的第一路由(106)上路由属于第一终点和第二终点(104)之间的通信隧道的数据帧。 至少一些数据帧包括连续性检查消息。 如果包括连续性检查消息的某些数据帧在网络(100)中丢失,则第一终点将属于通信隧道的数据帧重新路由到与第一路由(106)不同的第二路由。 对于该技术的方法方面,第一路由的至少一个链路被切换到减少的链路容量。 响应于第一路由(106)的中间点(110)中的至少一个的链路容量的减小,包括连续性检查消息的数据帧的至少一部分被丢弃。

    • 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.
    • 一种优先分组的方法,用于通过互连移动网络的节点的传输网络进行传送,其中为移动网络指定传输网络上的保证的最小信息速率。 该方法包括:对于从移动网络注入到传输网络中的每个承载,指定承载信息速率,并将分组标记为符合承载信息速率的分组,并将超过该速率的分组标记为不符合 承载信息率。 来自移动网络的多个业务类型流被收敛,每个业务类型流包括多个承载。 对聚合流量类型流的数据包进行检查,以识别标记为一致和不一致的数据包,并重新标记不一致的数据包,或至少一部分不符合数据包,如果一致性数据包的收敛速率为 小于最低信息速率。 传输网络优先考虑标记为不符合标准的数据包的标签传输。

    • 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.
    • 提供了一种通过电信传输网络传输数据分组的方法。 数据分组由多个承载携带,每个载体携带与多个服务中的不同服务相关的数据分组。 在该方法中,对于每个载体,独立于其他载体,带宽分布被应用于承载的数据分组,以识别和标记符合承载的所确定的最大信息速率的每个承载的数据分组。 转发数据包通过传输网络进行传输。 如果传输网络中没有足够的带宽来传输所有数据包,那么被分析不被识别为一致的数据包将被丢弃,以便不通过传输网络传输。 监视通过传输网络传输的载体的数据分组,以确定是否已经存在应该已经通过传输网络传输的数据分组的任何丢失,指示传输网络中的拥塞。 基于监控调整承载的最大信息速率。
