Abstract: A method performed by a first network node, for deciding a configuration to be used in a data communication between the first network node and a second network node in a wireless communications network is provided. The first network node receives a second message from the second network node. The second message includes user plane configuration information. The user plane configuration information includes a vendor identity of the second network node, a highest user plane protocol version supported by the second network node and a set of proprietary features of the vendor that are supported by the second network node. The second message is conveyed by using a frame structure according to a protocol specification that is being negotiated. The first network node decides a user plane vendor configuration to be used in the data communication between the first network node, and the second network node.

Abstract: An arrangement and method for choosing a route in a hierarchical transmission system including a plurality of interconnected nodes includes generating local routing tables in which routes between nodes on the same hierarchical level are saved and global routing tables in which routes between nodes on different hierarchical levels are saved. A route is chosen from the routing tables in response to a request for a connection between a source node and a destination node.

Abstract: The present invention relates to a method to optimise a selection of a route (Z) in a communication system having branch points (A-F) of transmission links (L1-L9). The quality of each link is represented by a topology metric value (TM) and a topology attribute value (TA).
