摘要： A method and system to manage network congestion are provided. In one example embodiment, the system comprises a congestion point queue, a monitor to sample a state of the congestion point queue, a consolidated parameter generator to generate a consolidated feedback parameter, and a feedback message generator to generate a feedback message, utilizing the consolidated feedback parameter. The congestion point queue may be configured to queue messages from a reaction point to a congestion point. The state of the congestion point queue may be reflected by an equilibrium queue level, a queue offset, and a rate of change of a size of the congestion point queue. The equilibrium queue level may represent a particular predetermined size of the congestion point queue. The queue offset may represent a deviation from the equilibrium queue level. The consolidated feedback parameter may be generated to reflect the queue offset and the rate of change of the size of the congestion point queue.

摘要： Methods and apparatus for congestion control in computer networks achieve high burst tolerance, low latency and high throughput with shallow-buffered switches. A method for controlling congestion includes transmitting a set of data packets on a network connection from a first computing device to a second computing device, identifying each data packet in the set of data packets that experienced congestion on the network connection, sending, by the second computing device to the first computing device, a sequence of bits that represents the number of data packets in the set of data packets that were identified as having experienced congestion, and adjusting a rate of transmitting data packets on the network connection based on the sequence of bits sent to the first computing device.

摘要： A circuit analysis tool is provided for optimizing circuit clock operating frequency using useful skew timing analysis. The instructions supply clock signal with an optimized operating frequency. A first gate signal input slack time is determined with respect to the clock signal to the first gate. If the first gate signal input has a negative slack time, a delay is added to the first clock signal. A second gate signal input slack time is determined with respect to the clock signal to the second gate. If the second gate signal input slack time is negative, a delay is added to the second clock signal necessary to create a second gate signal input positive slack time. In response to the first and second gate signal input positive slack times, it is determined that the circuit successfully operates at the clock optimized operating frequency.

摘要： In a packet-queue management system, a bandwidth allocation approach fairly addresses each of n flows that share the outgoing link of an otherwise congested router. According to an example embodiment of the invention, a buffer at the outgoing link is a simple FIFO, shared by packets belonging to the n flows. A packet priority-reduction (e.g., packet dropping) process is used to discriminate against the flows that submit more packets/sec than is allowed by their fair share. This packet management process therefore attempts to approximate a fair queuing policy. The embodiment is advantageously easy to implement and can control unresponsive or misbehaving flows with a minimum overhead.
