    • 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。

    • Congestion is detected in a radio access transport network including one or more radio network controllers each coupled to one or more radio base stations. Multiple data packet flows are each associated with a mobile radio terminal communication, and each flow is controlled in the radio access transport network by a corresponding flow control entity. They are monitored for congestion in the transport network. If a congestion area in the transport network is detected for one of the monitored data packet flows, then a determination is made whether other monitored data packet flows share the detected congestion area. Congestion notification information is communicated to the flow control entities corresponding to the other monitored data packet flows that share the detected congestion area. Based on the congestion notification information, the informed flow control entities may take a flow control action, e.g., to enable fair sharing of communications resources in the transport network.
    • 在包括耦合到一个或多个无线电基站的一个或多个无线电网络控制器的无线电接入传输网络中检测到拥塞。 多个数据分组流每个都与移动无线终端通信相关联,并且每个流由对应的流控制实体在无线接入传输网中进行控制。 监控他们在运输网络中的拥塞。 如果对所监视的数据分组流中的一个检测到传输网络中的拥塞区域,则确定其他监视的数据分组流是否共享检测到的拥塞区域。 拥塞通知信息被传送到与共享检测到的拥塞区域的其他监视数据分组流对应的流控制实体。 基于拥塞通知信息,通知流量控制实体可以采取流量控制动作,例如,以实现传输网络中的通信资源的公平共享。
