Abstract: An intermediate clock, either a boundary clock or a transparent clock, may have to adjust its local clock to match that of a grandmaster clock. If such adjustment is frequent or large, then the intermediate clock may not have much confidence in the reliability of the timing information it passes to a downstream clock in an IEEE 1588 Announce message even if the quality of its local clock is high. The intermediate clock determines a measure of the reliability of its timing information. The intermediate clock inserts an indication of the reliability of the timing information in a transmitted IEEE 1588 Announce message. The intermediate clock may consider an indication of reliability found in an Announce message it receives when inserting an indication of the reliability of timing information into an Announce message which it transmits.

Abstract: A method and system are provided for reducing bandwidth usage in TDM CES systems conveying analog data, such as voice data. A transmitting router receiving TDM frames for packetization monitors the digitized analog data in the TDM frames. If the analog data has not changed beyond a configured threshold for a configured length of time, the transmitting router signals the receiving router at the far end of a TDM Pseudowire that no packets for the TDM Pseudowire will be sent. The transmitting router does not send any packets over the TDM Pseudowire, not even packets with empty payloads. The receiving router a receiving such a signal starts to generate its own packets for placing in its jitter buffer. Valid data already within the jitter buffer is played out to the access port, but once this runs out dummy packets placed in the jitter buffer by the receiving router are played out. In this way the jitter buffer maintains its fill level even when no packets are being sent across the TDM Pseudowire.

Abstract: A method and system are provided for reducing bandwidth usage in TDM CES systems. When a transmitting router receives a signal that the status of the access circuit is other than “normal”, and that therefore any TDM data arriving over the access circuit is not valid, the transmitting router signals a receiving router at the far end of a TDM Pseudowire that no packets for the TDM Pseudowire will be sent, and does not send any packets over the TDM Pseudowire, not even packets with empty payloads. When the receiving router receives such a signal, it starts to generate its own packets for placing in its jitter buffer. Valid packets already within the jitter buffer are played out to the access port, but once this runs out dummy packets placed in the jitter buffer by the router are played out. In this way, the jitter buffer maintains its fill level even when no packets are being sent across the TDM Pseudowire.

The threshold may be a cap threshold where the size of the congestion window is prevented from exceeding the cap threshold. The threshold may be a reset threshold which may be used to control a reduction of the size of the congestion window.
