Problems solved by technology

The disadvantage of this method is that: different services have different traffic characteristics, which makes the bursting degree of each port traffic very different, and different services have different network quality requirements, which makes each port have a great tolerance to bursting difference
The method of setting a fixed expansion threshold for a type of port does not adapt well to this difference
Therefore, this expansion method is also unreasonable.

Abstract

The embodiment of the invention discloses a method and device for determining the network expansion. According to the embodiment of the invention, a reasonable method for formulating an expansion threshold is provided with consideration of differences among all ports and service requirements. The method comprises: historical running data of a port are obtained; according to the historical runningdata of the port, a correspondence relationship between a link utilization rate and a link loss rate is determined; according to link utilization rates and link loss rates corresponding to the link utilization rates, congestion coefficient estimation values corresponding to all link utilization rates are determined and a correspondence relationship between the link utilization rates and congestioncoefficient estimation values is obtained; a target congestion coefficient is determined; a target link utilization rate is obtained based on the target congestion coefficient and the correspondencerelationship between the link utilization rates and congestion coefficient estimation values; and whether expansion is needed is determined according to a relationship between an actual link utilization rate and an expansion threshold.

Description

Technical field [0001] The embodiment of the present invention relates to the field of computer network technology, and in particular to a method and device for determining network expansion. Background technique [0002] Currently, the actual expansion judgment schemes used in the live network mainly include the following two: [0003] 1. Based on the link utilization rate, a unified expansion threshold is set for all ports. When the link utilization rate exceeds the expansion threshold, it is determined that the port should be expanded. In practical applications, the difference in device cache capacity and the difference in the configuration of the buffer capacity for the port will make the tolerance of each port to congestion very different; the difference in the carrying service of the port will also make the tolerance of each port to congestion very different. very different. If all ports are set with a uniform expansion threshold, for some ports, when the link utilization e...
