Apparatus and method for providing a congestion measurement in a network

摘要

Example embodiments of a system and method for providing a congestion measurement in a network are disclosed. In an example embodiment information is received at an information transfer rate, from a source network device. A sample of the information may be taken before the information is transmitted to a destination network device. In an example embodiment, a congestion measurement value is computed that corresponds to the sample and represented with at least two bits. A multi-bit indicator of the congestion measurement value is then transmitted to control the information transfer rate of information arriving in the future.

主权项

1. An apparatus comprising:
a source network device including at least one input-output port to communicatively couple with a sink network device via a transmission medium, the source network device including:
a transmission control module to regulate an information transfer rate, the transmission control module being configured to:
reduce the information transfer rate in response to receiving a multi-bit indicator, wherein the multi-bit indicator is generated from a congestion measurement value to reduce a number of bits used to represent the congestion measurement value, wherein the congestion measurement value represents a measurement of network congestion, and wherein the multi-bit indicator is composed of m bits, the congestion measurement value is composed of n bits, and n is greater than m, andautomatically increase the information transfer rate after a predefined period of time.
