Description
Technical field
Evaluated the present invention relates to internet QoS in field, the internet particularly carried out in the operator network
Network quality test system and method.
Background technology
With the fast development of Chinese broadband internet, ever-increasing enterprise and home broadband customer group turn into old China hand
Believe the important profit growth point of operator.In order to which operator's Intranet QoS, lifting user's sense is effectively ensured
Know, solve the Important Problems such as the quality objective evaluation of IP network, active O＆M, fault fast positioning, business be visual, it is necessary to build
The network performance and quality of service monitoring system of a set of base broadband internet, build test platform on this basis, for interconnection
The quality test of net key business extends to final broadband user, complete based on covering by the simulation test of various access scenes
The end-to-end test system of portion's the Internet, applications scene, builds business end-to-end test model, with science and the test side quantified
Method, the experience data of the accurate network quality for obtaining Internet user end, and these data are collected, science arrange and point
Analysis, can position the bottleneck of network service quality difference, ensure that communication is interconnected, and improve Internet service O＆M level, section
About common carrier corporate client cost of serving, so as to provide scientific and effective foundation preferably to improve network operation.
The introducing of test system and evaluation method, can effectively improve common carrier network operation and safeguard, complain
Analysis is with handling, the orderly management efficiency such as acceptance of work.So as to set up comprehensive data network and QoS parameter system,
Realize comprehensive assessment and the monitoring of network quality and quality of service.
At present there is also the test system of the technology tested using probe machine is tested, such as Pu Tian companies, pass through portion
Affix one's name to test machine, different TCH test channel carries out the collection of data, but the quality of Pu Tian companies at present just for cellphone subscriber
Test, scene is single, and lacks comprehensive evaluation to test data, and system is not also to customer service system open interface.And build
Cost is higher, therefore the actual large-scale application of the technology there is also some problems.
The content of the invention
Goal of the invention：The technical problems to be solved by the invention are that there is provided a kind of internet in view of the shortcomings of the prior art
In network quality test system and method.
In order to solve the above-mentioned technical problem, the invention discloses the network quality test system in a kind of internet, including：
Central server, NM server, database and test probe；
The test probe is special hardware, is respectively deployed in the Access Layer of carrier network, convergence-level and core
Layer, can receive the test assignment assigned from NM server, the application program of dry run ordinary internet users, operational network
Order, test result is uploaded to NM server by ICP/IP protocol；One group of N number of probe shares central server, one
Individual database and NM server, N is natural number；
The database, for storing default test assignment, the preservation of probe upload parameter and the preservation of test result；
Wherein, the NM server, for determining whether to visit by identity authorization system and access control technology
Pin registering and logging, the state to probe is monitored management, sends test assignment to probe, collects the parameter letter that probe is uploaded
Breath, is preserved while being sent to database；
Wherein, identity authorization system is used for the identification certification for realizing real user, such as uses the RBAC (access of based role
Control technology), ensure that data resource is able to effectively use and manage in legal range, function includes the identity to network entity
Carry out overall identification, certification and empowerment management, it is ensured that the authenticity and trustability of entity.
Access control matrix (Access Contro1Matrix) is based on entity identification and identity identifying technology, and realization is based on
The dynamic access control and resource management techniques of faith mechanism, for providing support for upper layer security application, in the present invention may be used
Support network measure service.The system is directed to the operation requests of application system, is obtained according to from the local policy storehouse in database
Resource use and access control policy requirement, checking can use the credibility of voucher, and be entered according to local policy and available voucher
Whether row, which is trusted, is calculated and scheduling of resource, can be carried out and corresponding resource constraint with determining to access, and control result is handed over
Performed to corresponding network server.
The central server, for the geographical address according to probe, IP address forms probe distribution topology, formulates and survey
Trial is engaged in, and preserves to database, the test assignment is sent into the probe that the test assignment is specified by NM server
Node；The parameter in database is extracted, postitallation evaluation method outputs test result, and test result is passed through into external interface pair
User is fed back, while preserving to database.
The invention also discloses the network quality method of testing in a kind of internet, comprise the following steps：
