摘要： A congestion control method of a cellular communication system is disclosed. A first protocol data unit having a first sequence number is transmitted from a radio network controller to a base station via a transport network. The base station detects a congestion situation of the transport network by detecting loss of the first protocol data unit during transmission over the transport network. In response to detecting the congestion situation, a notification message indicative of the detected congestion situation is transmitted from the base station to the radio network controller via the interface of the transport network.

摘要： To increase the utilization of the radio link and to provide a low complexity approach to retransmission control with respect to a fragmenting transmission protocol and a stream of data packets considered for data transmission, there is provided a method of retransmission control with respect to a fragmenting transmission protocol and a stream of data packets considered for transmission. The method comprises the steps detecting (S12) data packets in the stream of data packets which are unnecessary retransmissions based on sequence numbers of the data packets, dropping (S14) data packets which are unnecessary retransmissions from the stream of data packets for setup of a modified stream of data packets, and transmitting (S16) the modified stream of data packets over a transmission link.

摘要： A technique for controlling network routing in a network (100) is provided. The network (100) includes a first end node (102) and a second end note (104). The end nodes are connectable along a first routing path (106) by at least one link (113). The network (100) further provides a second routing path (108) including the first end node (102) and the second end nodes (104). As to a method aspect of the technique, one or more queues (402) are provided. Each of the queues (402) serves at least one tunnel (Tunnel_1; Tunnel_2) along the first routing path (106). A switching of the tunnel (Tunnel_1) to the second routing path (108) is triggered based on a combination of two pieces of information. A piece of information includes information as to a queue build-up at the queue (504) serving the tunnel (Tunnel_1). Another piece of information includes information as to a capacity of the link (113) of the first routing path (106).

摘要： A method for congestion control in a transport network of a radio access network is disclosed. The method comprises receiving, by the control node, a first uplink flow through a first communication link in the transport network from a first radio access node and receiving, by the control node, a second uplink flow through a second communication link in the transport network from a second radio access node. If congestion is detected in the transport network for either uplink flow, the control node selectively triggers either Active Queue Management (AQM)-based congestion control at the control node, or local congestion control at the for the uplink flow. Triggering is carried out such that AQM-based congestion control is carried out for only one of the first uplink flow or the second uplink flow if congestion is detected for both the first uplink flow and the second uplink flow.

摘要： A method is provided for 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 a multi-level bandwidth profiling scheme is applied to the data packets of each bearer. A series of information rates are assigned to a bearer, the profiling scheme identifying and marking each data packet of the bearer based on a desired resource sharing according to the minimum information rate with which the packet is conformant. The marked 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 identified by the profiling and marked as only being conformant with a higher information rate are discarded before any data packets marked as being conformant with a lower information rate.

摘要： A method and a transmitting node for redirecting of a flow of data packets to a path of alternative paths, and a method and a receiving node for enabling redirection of a flow of data packets to a path of alternative paths, where data packets are marked with a value indicating the importance of the data packets. The method for directing directs one or more flows of data packets for the alternative paths, wherein data packets marked with a higher value are prioritized over data packets marked with a lower value. Based on feedback information, the transmitting node redirects a flow of data packets to a second path of the alternative paths, if the metric of congestion indicates a higher congestion on the first path than on the second path.
