METHODS AND FIRST, SECOND AND NETWORK NODES FOR MANAGING TRAFFIC CHARACTERISTICS

摘要

Methods and a first node (110),a second node (120) and a network node (130) for managing traffic characteristics of one or more packets on a connection are disclosed. The first node (110) exchanges(303), with the network node (130), traffic characteristic semantics and a common key for encryption of a traffic characteristic value to be applied for the one or more packets on the connection, wherein the traffic characteristic semantics include the traffic characteristic value and an associated characteristic for the one or more packets. Moreover, the first node (110) sends(309) the traffic characteristic value and the common key to the second node (120).The network node (130) checks and applies(312) the traffic characteristics value according to service policies of the network node (130).Next, the first node (110) exchanges(311),with the second node (120), payload which includes one or more packets over the connection. Information about the traffic characteristic value is included in a transport header of each packet carrying the payload.
