Embodiment Construction

[0047] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0048] The present invention is applied to the nth level (n>1) of the group fair scheduler. The current scheduling regards the scheduling result of the previous level as a connection, and each connection only contains one cell, and the group fair scheduler maintains each The virtual end time stamp of the connection regards the theoretically infinitely long connection as a queue containing only one cell, which greatly simplifies the time stamp calculation and selection work during scheduling.

[0049] For the current schedule, the virtual end time stamp is updated only in the following two cases:

Abstract

The fair scheduling method for grouping comprises: the current scheduling receives output from last one to select the signal element of a connection with minimal virtual end timescale; when the last result as new signal, the current scheduling updates the virtual end timescale on connection with said signal element; then, canceling the update by current scheduling. This invention decreases calculation amount to simplify update operation.

Description

technical field [0001] The invention belongs to the field of data communication, in particular to a method for group fair scheduling in group network communication such as IP (Internet Protocol, network protocol), ATM (Asynchronous Time division multiplexing, asynchronous transfer mode), a group fair scheduler and data communication equipment. Background technique [0002] In order to provide QoS (Quality of Service, quality of service) guaranteed service in packet network, as IP, ATM, must adopt appropriate packet fair scheduler to carry out packet fair queuing scheduling in packet network equipment, such as ATM switch, IP router, with Ensure the QoS performance of the network. [0003] QoS service parameters include packet delay, delay jitter, loss rate and throughput rate, etc. Different services require different QoS parameters. The delay of packets in the network can be divided into fixed delay and queuing delay. The queuing delay is mainly to determine the service ord...
