Method and apparatus for analysis processing and testing network resource utilization situation of transmission network

Abstract

The present invention relates to an analyzing and processing method of network resource utilization, which comprises collecting resource utilization parameters. If the maximum utilization rate of the time slot of the single multiplexing section and / or the maximum utilization rate of each group of end-to-end circuits are higher than the resource utilization rate, the alarming threshold activates the capacity-expanding alarm. The present invention also relates to a testing method of the network resource utilization, which comprises the following steps: collecting the resource utilization parameters; extracting the top N utilization rates of the time slot of single multiplexing section; finding out the link and / or circuit with utilization rate of the time slot of single multiplexing section and / or the utilization rate of each group of end-to-end circuits, which is higher than the alarming threshold of the resource utilization rate. If the business can be distributed, the link fault is restored and the business of the restored link fault is configured. The analyzing and processing method and the testing method can objectively describe the bottleneck of the network resources and the reasonableness of the resource utilization, prevent the traversal and comprehensive analysis of the network, analyze the bottleneck of the network and the utilization of the resources in an optimized method, and determine the optimal alarming time.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a method and device for analyzing and processing network resource utilization status of a transmission network, and a testing method and device for network resource utilization status of a transmission network. Background technique [0002] With the continuous development of various services, the role of the transmission network is changing from a single basic network to a service network, that is, the transmission network not only provides transmission channels for various service networks, but also provides bandwidth rental services for customers. Therefore, the market and business have higher and higher requirements on the quality and dynamic configuration capability of the transmission network. On the other hand, operators cannot rely on excessively increasing network redundancy to meet network performance, reliability, and user dynamic needs. Therefore,...

Problems solved by technology

Therefore, the redundant resources in the static SDH network improve the responsiveness of the network to services, but because all services are not considered as a whole, it will also cause unoptimized network configuration and lower resource utilization

[0005] For a dynamically configured network (such as Automatically Switched Optical Network, ASON), because the circuit time slot is configured in real time and can be optimized at any time, its restoration is based on the routing mechanism and does not reserve dedicated resources. Therefore, the network Both resource utilization and resource utilization are dynamically changing, and the above indicators cannot be counted

[0006] In short, there are three disadvantages in using existing resource utilization parameters to evaluate the rationality of network resource utilization and resource bottlenecks: First, these parameters are generally collected from network management, or obtained through simple statistics and mathematical transformations, and can only Reflecting the utilization of network resources from some aspects, it cannot reflect the impact of business models and networking models, and it is impossible to objectively describe the bottleneck of network resources and the rationality of resource use; second, for static networks with redundant resources or For a network with dynamic resource allocation, the above indicators cannot reflect the utilization of network resources at all; third, the number of parameters is too large to comprehensively describe the utilization of network resources, and the daily maintenance and evaluation of the network is not strong.

Due to the above limitations, network maintenance personnel cannot test and evaluate the utilization and rationality of network resources well, and guide the optimization and construction of the network, which is not conducive to the process and standardization of network maintenance
