Problems solved by technology

[0003] However, although IEEE802.3ad defines the frame structure and rules of link aggregation, it does not define which method to use to implement
The following situations may occur after link aggregation is performed on multiple physical ports: the port with high load transmission may encounter high burst traffic, causing the port traffic to exceed the limit; some physical ports forward data with high load, while other physical ports It is in a state of low traffic load and bandwidth is not fully utilized, resulting in waste of resources

Abstract

An embodiment of the invention discloses a flow distribution method and device for an aggregation link, an optical line terminal (OLT) and a medium. The flow distribution method for the aggregation link comprises the steps that: a predicted average rate of a port in a current monitoring period and a rate average value of a plurality of ports are predicted at least based on the port flow of the port in a previous monitoring period, wherein the rate average value is the average value of the predicted average rate; the port flow of a to-be-adjusted port in the current monitoring period is adjusted to an adjusted port according to a load sharing element, wherein the load sharing element comprises preset message length intervals of different rates in the port flow, the to-be-adjusted port is the port with the predicted flow rate larger than the rate average value, and the adjusted port is the port with the predicted flow rate smaller than the rate average value. The flow of each physical port of the aggregation link can be dynamically allocated, the load difference of each physical port is reduced, and resource waste is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of optical line terminals (OLTs), and in particular, relate to a traffic distribution method, device, optical line terminal and medium for aggregated links. Background technique [0002] With the promotion of 5G technology, various APPs with high bandwidth requirements are springing up like mushrooms after rain, which puts forward higher requirements for data forwarding of OLT central office equipment such as integrated access media gateway equipment. In the process of data forwarding, especially the data forwarding of super-large traffic, even a super-capable forwarding chip may face problems such as insufficient bandwidth, insufficient reliability of network transmission, and traffic blocking links. Link aggregation technology provides a solution. Link aggregation technology aggregates multiple physical links together to form a complete logical link. The aggregated link bandwidth wil...
