Method, device and system for determining network performance

Abstract

The invention provides a method, a device and a system for determining network performance, relates to the field of communication, and aims to enable an MDSC to monitor the network performance of a transmission network. The method comprises: a PNC receives an abstract topology of a target object from an MDSC, the target object comprising at least one of a link, a port, or a node in a transport network; the PNC determines the physical topology of the target object according to the abstract topology of the target object; the PNC determines physical performance parameters of the target object according to the physical topology of the target object; the PNC abstracts the physical performance parameters of the target object to obtain abstract performance parameters of the target object; the PNCreports abstract performance parameters of the target object to the MDSC; and the MDSC determines the network performance of the transport network according to the abstract performance parameters. The method is used for monitoring the network performance of a transport network.

Description

technical field [0001] The present application relates to the communication field, and in particular to a method, device and system for determining network performance. Background technique [0002] The abstract and control of traffic-engineered networks (ACTN) controller is a layered controller proposed based on specific scenarios and service requirements of operators. The ACTN controller can implement clustering and virtualization management of the transport network, shield network differences, and provide users with a single virtual network through a hierarchical abstract model. [0003] Such as figure 1 As shown, the ACTN controller system architecture includes at least one customer network controller (customer network controller, CNC), a multi-domain service coordinator (multi-domain service coordinator, MDSC) and at least one physical network controller (physical network controller, PNC) . Wherein, the PNC is connected with the transmission network and is used for m...

AI Technical Summary

Problems solved by technology

[0004] The network performance of the transmission network is an important basis for daily operation and maintenance and planning of the transmission network, but the PNC can only collect and report the network performance parameters corresponding to the physical topology of the transmission network to the MDSC; while the MDSC can only recognize the abstract topology of the transmission network, but cannot identify Network performance parameters corresponding to the physical topology of the transport network

This will cause MDSC to be unable to monitor the network performance of the transport network
