摘要： A method for measuring delay parameters in a packet switched network between node A and node B (20), each having a clock, is disclosed.The method includes the steps of: measuring a first relative one way delay (ROWD1) (21) from node A to node B, measuring a second relative one way delay (ROWD2) (21) from node B to node A and calculating the difference between the first and second relative one way delays for providing a relative one way delay (ROWD) parameter. Methods for improving TCP protocol and detecting congestion in a packetswitched network using ROWD measurements are also provided.

摘要： A method for communicating between users (12, 14,1 6, 18) which employ a plurality of communication devices over a packet switched network (10). The method includes the steps of receiving a precommunication request (202) for a communication device or devices of said recipient to which said communication should be sent, determining in accordance with a communication receipt preferences (204) of the recipient which communication device or devices should receive said communication (206) and transmitting an indication (208) to the requester to which communication device or devices said communication should be transmitted. The communication itself may be a single media or a multimedia communication.
