Description
Technical field
The present invention relates to network communications technology field, relate in particular to a kind of analysis and processing method and device thereof of transmission network network resource usage situation, and a kind of method of testing and device thereof of transmission network network resource usage situation.
Background technology
Along with the development of all kinds of business, transmission network just by single facilities network to the service network role transforming, namely transmission network not only for the miscellaneous service network provides Transfer pipe, also can be the client bandwidth leasing service is provided.Therefore market and business are more and more higher to quality and the dynamic-configuration Capability Requirement of transmission network.On the other hand, operator can not rely on excessive increase network redundancy to satisfy network performance, reliability and user's dynamic need, therefore operator needs awareness network resource utilization and network running quality at any time, in order in time optimize and dilatation, in the situation that the network investment minimum ensures service quality.
At present, the parameter of description Synchronous Digital Hierarchy (being called for short SDH) transmission network device resource utilance comprises: group's road port utilization rate, tributary port utilization rate, group groove position, road utilization rate, bypass channel position utilization rate, intersection resource utilization, line time slot utilization rate etc.In addition, also have some to describe the parameter of resource utilization from network perspective, Internet usage usefulness for example, single hop percentage of circuit utilization, lattice network utilance etc.
For the network of static configuration, or certain section link circuit resource deficiency not enough due to certain circuit resource causes the network capacity extension often.For example have bottleneck point in SDH multiplexing section protection rings (MS-SPRING), make the time slot of fractional reuse section take, and the time slot of some other multiplex section is a large amount of idle; And according at that time service distribution, these free timeslots often can not use within a period of time.This is because networking structure, circuit planning do not mate with service distribution the resource utilization reduction that causes.On the other hand, for the inconsistency of practical business and prediction, can reserve some redundant resources in the network capacity extension, for example port resource, chain time gap resource and the resource of intersecting, if some business can not utilize the circuit of having opened to dredge, adopt these redundant resource configuration circuits.Therefore, the redundant resource in static SDH network has improved the responding ability of network to business, but owing to there is no whole all business of considering, that also can cause network configuration does not optimize reduction with resource utilization.
For the dynamic-configuration network (as ASON, ASON), because the circuit time slot is configuration in real time, and can be optimized at any time, its recovery is to adopt routing mechanism, do not reserve specific resource, so the resource utilization of network and resource utilization be all dynamic change, above index can't be added up.
In a word, adopt existing resource utilance parameter to come critic network utilization of resources rationality and resource bottleneck to have the shortcoming of three aspects: first, these parameters are generally collected from webmaster, perhaps obtain by simple statistics and mathematic(al) manipulation, can only be from some side reflection network resource usage situation, can't reflect the impact of business model and network model, the reasonability that bottleneck that also just can't the objective description Internet resources and resource are used; The second, for the network of the static network with redundant resource or dynamic resource configuration, above index can't reflect the network resource usage situation at all; The 3rd, number of parameters is numerous, can't comprehensive description network resource usage situation, and to regular maintenance and the assessment of network, directiveness is not strong.Owing to existing above limitation to make the network maintenance staff can not test well and critic network resource utilization and reasonability, and guide optimization and the construction of network, be unfavorable for procedure and the standardization of network operation.
Summary of the invention
Technical problem to be solved by this invention is the deficiency for the prior art existence, a kind of analyzing and processing, method of testing and device of transmission network network resource usage situation are provided, can utilize situation to assess and analyze to transport network resources more all sidedly, instruct maintenance of network, optimization and construction.
For this reason, the invention provides a kind of analysis and processing method of network resource usage situation, wherein, comprise the steps:
Step 2, judge in described condition parameter maximum single multiplex section time slot utilization rate and/or maximum every group terminal to the terminal circuit utilization rate whether greater than the resource utilization alarming threshold, if so, start the dilatation alarm; If not, finish.
The invention provides a kind of APU of network resource usage situation, wherein, comprising:
One harvester is used for gathering current network resources and utilizes condition parameter;
One first comparison means, be used for extracting the single multiplex section time slot of described harvester utilization rate parameter and every group terminal to terminal circuit utilization rate parameter, and judge maximum single multiplex section time slot utilization rate and maximum every group terminal to the terminal circuit utilization rate whether greater than the resource utilization alarming threshold;
