Patent CA-2398531-A1 (CA)
Inventor: SIMARD FREDERIC
IPC: H04B10/294
Filed: 2001-12-07
Abstract: A performance monitoring method for an optically amplified transmission system. The method provides the optical power at each amplifier site, taking into account the inaccuracies introduced by the SRS in the power estimation obtained with the current methods. An optical spectrum analyzer is used at the output of the transmission link of interest to accurately measure the output power of each wavelength. This value is sent upstream to the last amplifier in the link, to compute an error term as the difference between the actual measurement and the estimation. The error term is used to infer the SRS-induced error by system elements not accounted for in the model. The error term is then fed-back to each amplifier in the link, so that the estimated power is adjusted to account for the SRS-induced inaccuracy.

Title: A technique for compressing a header field in a data packet
Inventor: LE KHIEM
IPC: H04W36/00
Filed: 2001-03-09
Abstract: A timer based header compression/decompression technique and timer and reference based technique are provided. A source generates a header field, such as an RTP time stamp.  A packet including the header field is sent to a compressor which calculates a compressed header field based on the header field of the packet from the source and a jitter quantity. The compressed header field is calculated by calculating a jitter effect the network before the compressor has on the transmission of packets and calculating a jitter effect the network between the compressor and a decompressor has on the transmission of packets. The packet including the compressed header field is transmitted to a decompressor which includes a local timer. The decompressor decompresses the compressed header field by calculating, an approximation of the header field based on the elapsed time since the arrival of a previous packet and the field value in the previous packet. The approximation of the header field is then corrected based on the compressed heater field provided in the packet.
