Abstract: A jitter-based transmission control method is disclosed. In the jitter-based transmission control method, several packets are sent applying a current congestion window size by at least one sender device through a network switch device. An immediate jitter ratio of the network switch device is calculated by the sender device. An average jitter ratio of the network switch device is updated by the sender device according to the immediate jitter ratio and the current congestion window size. The current congestion window size is reduced when the immediate jitter ratio or the updated average jitter ratio is positive and larger than a queued threshold over the current congestion window size, such that the packets are sent applying the reduced current congestion window size.

Abstract: Eye diagram scan circuit and associated method for a receiver circuit, including a level adjust circuit, a phase interpolator and a control module. The receiver circuit provides a first data signal and a primary phase data according to a received signal. The control module provides a phase offset data and a level offset data. The level adjust circuit adjusts a level of the received signal in respond to the level offset data; the phase interpolator triggers according to a sum of the phase offset data and the primary phase data, so a second data signal is provide in response to the level-adjusted received signal. The control module compares the first data signal and the second data signal, and accordingly provides an eye diagram scan result for the phase offset data and the level offset data.

Abstract: Embodiments of a synchronous data system and method for generating phase-aligned output data are generally described herein. In some embodiments, the synchronous data system includes a plurality of transmitter-receiver (TX-RX) pairs, each associated with a delay-locked loop (DLL) and arranged to generate corresponding output data stream based on a high-speed clock of the associated TX-RX pair. The DLL associated with each TX-RX pair is a phase-shifter DLL that includes an adjustable phase shifter arranged to minimize the phase error between the system clock and the module clock to edge-align the high-speed clocks of each TX-RX pair.

Abstract: Delivery of protocol data units or other suitable data or information units in various communication systems can be enhanced by appropriate methods and devices. For example, in-sequence delivery of protocol data units received in parallel from several lower-layer acknowledged-mode protocol entities may benefit from timers and/or forwarding status reports. A method can include observing a gap in a sequence of protocol data units received from a plurality of lower-layer protocol entities providing data transfer. The method can also include starting a timer upon the gap observation. The method can further include preventing the gap from blocking delivery of service data units to a higher layer, when the timer expires. The method can additionally include detecting a forwarding-status report. The method can also include immediately proceeding with data delivery to higher layer, containing the gaps because of the lack of forwarding at handover.

Abstract: The patent application discloses mechanisms that, for a given channel step or edge response, bit interval, and data dependent jitter table can directly determine the minimal eye or bit error rate opening by building a worst case pattern considering the effect of data dependent jitter. These mechanisms can be based on building an indexed table of jitter samples, preparing a structure in the form of connected elements corresponding to the jitter samples, and then applying dynamic programming to determine paths through the connected elements.
