Abstract: Due to massive available spectrum in the millimeter wave (mmWave) bands, cellular systems in these frequencies may provide orders of magnitude greater capacity than networks in conventional lower frequency bands. However, due to high susceptibility to blocking, mmWave links can be extremely intermittent in quality. This combination of high peak throughputs and intermittency can cause significant challenges in end-to-end transport-layer mechanisms such as TCP, such as the challenging problem of bufferbloat. Specifically, with current buffering and congestion control mechanisms, high throughput-high variable links can lead to excessive buffers incurring long latency. A dynamic receive window approach addresses the problem of bufferbloat.

Abstract: A method for estimating round-trip time (RTT) values for data packets travelling in a telecommunication network is disclosed. During a first time interval (206) which begins with the start of a data transmission, estimated RTT values (14) are generated by filtering a periodic sequence of RTT samples (12) with a self-initializing expanding memory polynomial (EMP) filter (16) and, after a first switch-over time at the end of the first time interval, the estimated RTT values are generated by filtering the RTT samples with a fading memory polynomial (FMP) filter (18). The first switch-over time is determined by comparing an FMP estimation error and an EMP estimation error, where the FMP estimation error is the difference between an output of the FMP filter and the RTT samples, and the EMP estimation error is the difference between an output of the EMP filter and the RTT samples, and triggering the first switch-over time when the FMP estimation error becomes equal to or less than the EMP estimation error.

Abstract: A system and method are described to provide a next generation cable gateway/modem based on the DOCSIS standard with a scheme to synchronously combine channels in the physical layer to increase overall bit rates for coaxial cable data transmission. The systems and methods synchronize the counters associated with multiple channels, including continuity counters, at the transmitter to zero and then allow the counters on individual channels to increment individually.

In this manner, the buffer acts to essentially equalize delays in individual channels with the continuity counter representing the mechanism for specifying the individual delays for the separate channels.
