Method, device and system for optimizing link traffic

Abstract

The embodiment of the invention discloses a method, a device and a system for optimizing link traffic. The method comprises the following steps: performing periodic sampling on traffic signals of a link to acquire historical traffic signal data; filtering high-frequency signal components in the historical traffic signal data according to a scheduled strategy to obtain a traffic signal predictive value based on stable traffic variation; comparing the traffic signal predictive value with a limit value of the current traffic signal; if the traffic signal predictive value is larger than a maximumvalue of the current traffic signal, establishing a bypass path; or if the traffic signal predictive value is smaller than a minimum value of the current traffic signal, deleting a bypass path. The method, the device and the system for optimizing the link traffic are adopted to predict the medium and long term variation trends of the traffic based on the historical statistics of the link traffic and decide to establish or delete the bypass path, thereby optimizing the link traffic and improving the stability of a network and the utilization rate of network resources.

Description

technical field [0001] The present invention relates to communication technology, in particular to a method, device and system for optimizing link traffic. Background technique [0002] The structure of the communication network usually adopts a layered form, and different layers provide different functions. At present, the most common is that the upper layer adopts the Internet Protocol Layer (IP, Internet Protocol) or Multi-Protocol Label Switching (MPLS, Multi-Protocol Label Switching) in the form of packets, and the lower layer can be Ethernet, Synchronous Digital Hierarchy (SDH, Synchronous Digital Hierarchy) Or Optical Channel Data Unit (ODU, Optical Channel Data Unit), the lowest layer adopts the wavelength channel. When providing link traffic engineering, the optimal path is calculated from the perspective of a single layer, and the overall optimization cannot be achieved. [0003] Multi-layer traffic engineering aims to provide an overall optimal path starting fro...

Problems solved by technology

[0005] However, in an actual network, IP traffic is bursty, and the traffic fluctuates greatly. Too frequent triggers to establish and delete bypass paths will affect the stability of the network and lead to a decrease in the utilization of network resources.
