摘要
The invention provides a method for negotiating datapath treatment for traffic sourced from a first communications network (10) over an end-to-end path in respect of a path segment provided for said traffic in a second communications network (20) , the path segment being requested for a first node (8a) of the second communications network (20) and being targeted to a second node (12) of the second communications node (20) . The method comprises: for the first node (8a) , notifying that a datapath capability for the path segment is one for selection for the second node (12) ; communicating datapath capabilities associated with the first node (8a) ; selecting, for the second node (12) , a datapath capability from the datapath capabilities so communicated; communicating the datapath capability so selected for the second node (12) back to the first node (8a) ; and wherein the path segment is established using a signaling protocol of the second communications network (20) . The invention may also be implemented in a corresponding communications node.
