Abstract: A method in a first network entity which is capable of communicating over a plurality of communication links with a second network entity. The first network entity determines a level of transmit traffic transmitted over the plurality of communication links to the second network entity. The first network entity further determines a level of receive traffic received over the plurality of communication links from the second network entity. The first network entity further determines if the level of transmit traffic and/or the level of receive traffic meet one or more requirements for changing a number of active links of the communication links. If so, the first network entity changes the number of active links independently of the second network entity.

Abstract: A network management system (NMS) for a communications network has communications apparatus capable of being operated in different power consumption modes to provide different levels of performance, has a path computation apparatus configured to select paths for the traffic using the communications apparatus, based on information about traffic load in the network and on information about the power consumption modes of the communications apparatus of at least one of the nodes. A power mode controller is also provided for controlling the power consumption modes of the communications apparatus according to information about traffic load and according to information about the paths selected. By combining of path computation and the control of power consumption modes the overall power consumption of the network can be reduced. A slave power mode controller can be provided.

Abstract: The present invention relates to methods for indicating a bonding configuration mismatch of lines of bonding groups. The methods are performed in different nodes of a communications network. Said method comprises sending a Bonding Configuration Value via one line of the bonding group of lines, said Bonding Configuration Value being unique for said bonding group, and receiving a Bonding Configuration Value via each of the lines of the bonding group. It further comprises checking each received Bonding Configuration Value for diverging values. If a diverging Bonding Configuration Value is identified, an alarm message is generated and sent to Element Manager of the communications network.
