Abstract: The present solution relates to a method in a first communication node for (101) improving bandwidth utilization in a wireless communication system (100). The system comprises at least two communication links (110, 112) between the first communication node (101) and a second communication node (105). First, the first node (101) receives (501) data.

Link quality based on communication link quality measurements of the at least two communication links (110, 112) is then determined (504), before the data is sent (509) on one of the at least two communication links (110, 112) to the second communication node (105). The chosen link being based on the quality measurements.

Abstract: The embodiments herein relate to a method in a first unit for determining location of deteriorating hardware. The first unit obtains information indicating a first signal level of a first signal and a second signal level of a second signal transmitted over a wired communication link and over a period of time. The first unit monitors the first signal level and the second signal level over the period of time. When a deviation in the monitored signal levels has been detected, the first unit determines a location of the deteriorating hardware by comparing the deviation in monitored signal levels to known signal deviations for various locations of the deteriorating hardware. The location is in at least one of the wired communication link, the second unit and the third unit.

Abstract: 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.

Abstract: 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).

Abstract: The present invention relates to a digital bus system (1; 1a) of low power consumption. The bus system (1; 1a) is adapted to establish at least one parameter (M; M1) that indicates the number of transmitter units (9.1-9.N) in the bus system (1; 1a) which need to send data on a data bus (3). A clock signal (CLK2) that indicates a rate at which data is sent is generated with regard to the established parameter (M; M1) in accordance with a predetermined pattern. In this respect, the clock signal (CLK2) is generated in a manner such that the fewer the transmitter units (9.1-9.N) needing to send data, the lower the data rate on the data bus (3). This reduces the average power consumption of the transmitter units (9.1-9.N) and receiver (15). This lower power consumption is achieved without appreciably affecting waiting times in respect of transmitter units (9.1-9.
