摘要： The present invention relates to methods and devices (11, 12, 14) for transmitting a sequence of data packets in a network. To this end, a send rate with which the sequence is to be transmitted is selected. Then, a first set of data packets of the sequence is transmitted and the transmission is associated with a time stamp. Finally a last data packet of the sequence is transmitted after a predetermined time interval has elapsed from the time stamp associated with the first set of data packets, where said predetermined time interval is the time required for transmitting the sequence of data packets with the selected send rate.

摘要： The embodiments of the present invention relate to a method in a transmitting node; a method in a receiving node; a transmitting node and a receiving node in an IP network employing Internet security. The receiving node comprises a Receiving Unit, a Processing Unit and a Transmitting Unit. When an IP packet is received, the Processing Unit is adapted to derive a Security Association and a Traffic Class associated with the IP packet. The Processing unit is also adapted to maintain one anti-replay window for each Traffic Class within the Security Association and to determine if a sequence number of the IP packet is within the anti-replay window of the Traffic Class and is not a duplicate of an earlier received packet. If said sequence number is not within the anti-replay window or is a duplicate of an earlier received packet, the packet is dropped.
