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 present invention discloses a method and device for determining network capacity expansion. The embodiment of the present invention provides a reasonable method for formulating a capacity expansion threshold in consideration of differences between ports and service requirements. The method includes: obtaining port historical operation data; determining the corresponding relationship between link utilization rate and the link packet loss rate according to the port historical operation data; according to the link utilization rate and the link utilization rate corresponding to the link Packet loss rate, determine the estimated value of the congestion coefficient corresponding to the utilization rate of each link, and obtain the corresponding relationship between the link utilization rate and the estimated value of the congestion coefficient; determine the target congestion coefficient; according to the target congestion coefficient and the link utilization rate and the congestion coefficient According to the corresponding relationship of the estimated value, the target link utilization rate is obtained; according to the relationship between the actual link utilization rate and the expansion threshold, it is judged whether expansion is required.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of computer networks, and in particular to a method and device for determining network capacity expansion. Background technique [0002] At present, the expansion discrimination schemes actually adopted in the live network mainly include the following two types: [0003] 1. Based on the link utilization rate, set a unified expansion threshold for all ports. When the link utilization rate exceeds the expansion threshold, it is judged that the port should be expanded. In practical applications, the difference in device buffering capabilities and the difference in the buffering capacity configured for ports will make the tolerance of each port to congestion very different; very different. If a unified expansion threshold is set for all ports, for some ports, when the link utilization exceeds the expansion threshold, there may not be packet loss and expansion is not required; There are h...
