Method for controlling traffics among channels in architecture of network element based on forwarding and control separation

Abstract

The invention discloses a method for controlling traffics among channels in the architecture of a network element based on forwarding and control separation. The method comprises the following steps: (1) a global topological structure inside the whole network element is constructed at a control element end according to information reported by a forwarding element; (2) traffic matrix models for the traffics among the channels inside the network element are established through a Kallman filtering estimation method by using the constructed global topological structure; (3) message transmission rates of the channels inside the network element at a next moment are predicted according to acquired traffic information at a current moment based on the obtained traffic matrix models; (4) reasonable available bandwidth is distributed for each channel by a control element according to the predicted traffic rate of each channel; and (5) the control element updates the global topological structure of the network element, the operation is switched to the step (2) if the topological structure is changed, and the operation is switched to the step (4) if the topological structure is not changed. The method for controlling the traffics among the channels in the architecture of the network element based on forwarding and control separation has the advantages that a bandwidth distribution method capable of avoiding the congestion of the traffics among the channels is achieved, and the requirements for a new-generation network facing the integration of three networks are met.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a flow control method between channels in a network element architecture based on separation of forwarding and control.
