Abstract
A method (), performed by a first network node in a communication network, is disclosed. The first network node is connected to a second network node of the communication network via an interface implementing a GPRS Tunnelling Protocol (GTP). The method comprises selecting a user data packet for transmission to the second network node () and identifying information about the user data packet which impacts how the user data packet should be routed over the interface (). The method further comprises encoding the identified information into a User Datagram Protocol (UDP) header of the user data packet () and forwarding the user data packet to the interface for transmission to the second network node (). Another method () is disclosed, performed by a node in a Mobile Transport Network, the Mobile Transport Network providing a GTP based interface between a first network node of a communication network and a second network node of the communication network. The method comprises receiving a user data packet from the first network node for transmission over the interface to the second network node (), extracting, from a UDP header of the user data packet, information about the user data packet which impacts how the user data packet should be routed over the interface () and using the extracted information in a routing decision to forward the user data packet to the second network node (). Also disclosed are a communication network node (), a Mobile Transport Network node () and a computer program configured to carry out methods in a communication network node and a Mobile Transport Network node.
