Embodiment

Below by specific embodiments and the drawings the present invention is described in further details.

Core technology scheme of the present invention is: service provider (SP) equipment is formulated SLA services quality monitoring strategy according to the SLA that signs in advance, and is distributed to Virtual network operator (NO) equipment; This SLA services quality monitoring strategy of NO device start is monitored collection to the performance parameter that this monitoring policy is formulated, and reports the performance parameter of being monitored to SP equipment, and SP equipment is determined SLA service quality according to the performance parameter that reports.

The SLA that described SP signs in advance can for: with the SLA that the specific user signs, the monitoring policy of its formulation (in order to simplify statement, what described herein monitoring policy referred to is exactly SLA services quality monitoring strategy) is the monitoring policy to this specific user; The SLA that described SP signs in advance also can for: with the SLA that Virtual network operator is signed, the strategy of the monitoring policy of its appointment for the network of this Virtual network operator is monitored.

Management for convenience, make product modular, the present invention need be provided with the Service Quality Management device in service provider's network, be used to develop and publish SLA services quality monitoring strategy, and receive the performance parameter that Virtual network operator equipment reports, determine SLA service quality with this performance parameter.For the interface that carries out the service order monitoring of a unification is provided in NO, the present invention is provided with the performance strategy processor in the network of NO; Be used to receive the SLA services quality monitoring strategy of SP equipment issue, start and carry out observation process, and report monitoring result.

Performance strategy processor of the present invention has two kinds to the monitoring acquisition method of performance parameter:

1, the performance detector is set on the network equipment of Virtual network operator, performance parameter to this network equipment is surveyed, and report described performance strategy processor, the performance detector is relevant with service, for example can monitor FTP service, WEB service, also the user can be distinguished, station address even serve port can be distinguished;

2, the management equipment in the Virtual network operator network (for example Element management system EMS and/or network management system NMS) reports described performance strategy processor with the network performance parameter of self monitoring, the performance parameter that management equipment reports has reflected the ruuning situation of network, and is irrelevant with concrete service.

First embodiment of the method for the invention: ensure the SLA that SP and specific user sign.Among this first embodiment, SP and the user that certain is specific sign SLA, are stored in the Service Quality Management device, and the Service Quality Management device is monitored service quality according to this SLA.

Fig. 2 is the flow chart of the method for the invention first embodiment.Referring to Fig. 1, this flow process comprises:

Step 201, service provider trigger the SLA services quality monitoring process that starts according to own service characteristics and/or SLA on specific opportunity.

Include but not limited to described specific opportunity: when the custom system request is served or custom system find that service quality descends and when initiatively reporting property abnormality to report.For example, when service providing server provides financial service etc. to the high service of particular network performance requirement, then when user request service, start described observation process, finish up to service; When being provided, ordinary audio dialogue service then can at network performance parameter (for example postponing) when reaching a certain threshold value, report the property abnormality report to start described observation process by custom system.The enabled instruction of described SLA services quality monitoring can directly send to the Service Quality Management device by custom system, also can send to the Service Quality Management device by service providing server.

Start described SLA services quality monitoring process when being the custom system exception reporting specific opportunity shown in Figure 2.In this kind situation, to service providing server request service, under normal circumstances, service providing server provides service for the user to custom system by communication network.Custom system directly or by service providing server sends exception reporting to the Service Quality Management device perceiving service performance when unusual or service performance trend when worsening indirectly by interface; In the specific implementation of this process, custom system can but be not limited to: survey service performance, and by upload service information directly or indirectly to the Service Quality Management device, unusual to detect service performance; In custom system at each parameter setting threshold value, when service performance reaches threshold value when restriction, promptly as the unusual reporting service quality manager of service performance.

Following steps 202 are SLA services quality monitoring process to step 218.

Step 202, SLA services quality monitoring process start, and the Service Quality Management device is formulated monitoring policy according to the SLA that is signed, and monitoring policy is published to the performance strategy processor, and the control performance policy handler may starts the SLA services quality monitoring.

Described monitoring policy mainly is provided with the monitoring scheme of network performance parameter and processing action when unusual etc. to the key network performance parameter.Concrete, monitoring policy can be divided into interim strategy and long term policy.Interim strategy is used for network performance parameter is monitored provisionally, for example at a user who signs platinum service class SLA (service quality of its requirement is very high), can make interim strategy at this user separately, in real time the network performance parameter to the service that provides for this user carries out independent monitoring, and before property abnormality takes place or during generation, in time carry out abnormality processing or report to custom system; Long term policy then is to be stored in the performance strategy processor, be responsible for the monitoring of long-term basic network performance parameter, for example at the domestic consumer that has signed " service as far as possible " type SLA (service quality of its requirement is lower), can specify out long term policy to carry out whole monitoring, the network performance parameter of monitoring can be used for ex-post analysis service quality, the network performance situation that can also supervising network operator provides for the service provider.

The present invention can formulate a monitoring policy to a user, also can formulate a monitoring policy to a class user, also may formulate a monitoring policy at the overall network of operator, perhaps also can formulate monitoring policy at certain special circumstances.Formulating the situation of monitoring policy can be selected arbitrarily by the user, no longer enumerates herein.

A monitoring policy can be made up of one or more monitoring instructions, also includes but not limited in addition: type of policy issue person's identification information, strategy or the like.Each monitoring instruction it may be noted that the performance parameter and the corresponding attribute thereof of a needs monitoring at least, for example, need the performance parameter of monitoring to comprise bandwidth, fault time, recovery time, shake, time delay, packet loss etc., its corresponding attribute information comprise such as: what the user's that this monitoring instruction is monitored sign, user's address information (for example IP address in the IP network), port numbers, current needs were monitored is information such as TCP connection or UDP connection; In the monitoring instruction can also including but not limited to: the normal codomain of the performance parameter of being monitored and monitoring result are violated the command information of this normal thresholding time institute trigger action.

In order to make the Service Quality Management device formulate corresponding monitoring policy according to SLA, the present invention preestablishes the mapping relations table that the QoS parameter of storing among the SLA (for example KQI) arrives performance parameter (for example KPI) in the Service Quality Management device.In this mapping relations table, a QoS parameter can be mapped as one or more than one performance parameters, usually by this one or more performance parameter is carried out computing and processing, can obtain corresponding QoS parameter.

For example, Fig. 3 is the concrete example schematic diagram that QoS parameter arrives the mapping relations of performance parameter among the SLA.Referring to Fig. 3, in this example, the QoS parameter of signing in the described customer sla comprises: bandwidth reserved (requiring to be 2M), mean failure rate recovery time (requiring smaller or equal to 110ms).In the corresponding mapping relations table, the performance parameter of described bandwidth reserved correspondence is the network bandwidth, and the performance parameter of described mean failure rate correspondence recovery time is fault time and recovery time.

Fig. 4 formulates the schematic flow sheet of monitoring policy for the Service Quality Management device.Referring to Fig. 4, sign SLA and be the process that example illustrates formulation monitoring policy of the present invention with SP and specific user for this SLA formulates monitoring policy, among Fig. 4 the information on the left side for importing, the back be output information, this formulation process comprises:

Step 401, obtain user's customizing messages, for example user's id information and station address information from custom system and/or service providing server.

Step 402, the QoS parameter information from the SLA database among the retrieval SLA that this user signed.For example, retrieving QoS parameter information herein from the described SLA of Fig. 3 is bandwidth reserved and average failure recovery time.

In last two steps, if generate the monitoring policy of the SLA of SP and NO signing, then obtained the customizing messages of NO, and in the SLA database, retrieve the SLA that this NO signs.

Step 403, according to described mapping relations table, each QoS parameter that retrieves is mapped as performance parameter.For example, bandwidth reserved is mapped as the network bandwidth herein, mean failure rate is mapped as fault time and recovery time recovery time.

Step 404, be that user ID and station address are combined into the monitoring instruction with owner's information of performance parameter and SLA.For example, generate three monitoring instructions herein: one for user ID or station address add the network bandwidth, represent that monitoring network provides the bandwidth of service for this user; Article one, for user ID or station address add fault time, represent the fault time when monitoring network provides service for this user; Another adds recovery time for user ID or station address, the recovery time when the expression monitoring network provides service for this user.

Set additional policy owner information (promptly generating the sign of the Service Quality Management device of this monitoring policy) and policing type information additional informations such as (for example being interim strategy or long term policy) that step 405, the monitoring that will generate are instructed generate monitoring policy.

After generating monitoring policy and being handed down to the performance strategy processor, continue to carry out following SLA services quality monitoring process.

Step 203, performance strategy processor are safeguarded processing at the monitoring policy of receiving, for example distribute unique ID (being SID) for this monitoring policy, distribute required computational resource of this monitoring policy and storage resources (for example cpu resource, memory source, thread resources and hardware store resource etc.), if monitoring policy is the long term monitoring strategy then needs this long term monitoring strategy is kept in hard disk or the database for a long time, and carry out operation such as updating maintenance.The performance strategy processor successfully receive and carry out above-mentioned safeguard treatment S LA services quality monitoring strategy after, return strategy handle successful message and for unique SID of strategy distribution to the Service Quality Management device.

Step 204～207, the Service Quality Management device sends and starts policy instructions to the performance strategy processor, SID comprising the monitoring policy that is started, the performance strategy processor is according to the monitoring policy of indication in this instruction, notice starts the involved performance detector of this monitoring policy and monitors needing the performance parameter of monitoring in this monitoring policy, described performance detector starts monitoring to described performance parameter, and (concrete monitoring method has difference at different performance parameters, can utilize existing monitoring method to realize), return success after starting successfully and respond the performance strategy processor, the performance strategy processor returns success and responds the Service Quality Management device.

The process that concrete notice starts the monitoring performance parameter is: the performance strategy processor sends broadcast, wherein carry the pointed station address information of monitoring instruction in the current monitoring policy, the performance detector judges according to station address information whether this user is the user who self has jurisdiction over after receiving broadcasting, be to judge that then this performance detector is the related performance detector of current monitoring policy, return the sign of this performance detector to the performance policy handler may, the performance strategy processor sends enabled instruction to the performance detector that returns sign, wherein carry in the current monitoring policy the pointed performance parameter of monitoring instruction, the performance detector is received the monitoring that starts after the enabled instruction described performance parameter.

Step 208, performance detector are monitored performance parameter, the primitive network performance parameter (i.e. original performance parameter shown in the figure) that is monitored to performance policy handler may report.Described primitive network performance parameter can include but not limited to: the bag number of bandwidth information, fault message, packet loss information, TCP/UDP flow information, transmission and the deferred message of each bag etc.For example primitive network performance parameter herein can be the network bandwidth, fault time and recovery time.

KPI and/or the KQI that (for example classify, processing such as integration, analyzing and processing) generates the reflection network performance parameter handled to the primitive network performance parameter information of uploading from the performance detector in step 209～210, performance strategy processor, this KPI and/or KQI are uploaded to the owner of current monitoring policy, promptly issue this monitoring policy Service Quality Management device.In addition, the performance strategy processor can also trigger corresponding abnormality processing action at the abnormal information that becomes among KPI and/or the KQI, for example sends alarm operation to network management system.

Herein, why the performance strategy processor is handled the primitive network performance parameter is because some original performance parameter also can't satisfy desired KPI of monitoring policy and/or KQI, for example monitoring policy needs the failure rate of Monitoring Service related network device, the performance parameter that reports up is the service related network device number of faults of a period of time, then need carry out computing, be about to number of faults divided by the unit interval, obtain failure rate.Why say herein handle obtain KPI and/or KQI be because: some original performance parameter can directly be treated to KQI, and some original performance parameter then is KPI, and this is relevant with the concrete KPI and the KQI that are monitored.

The default operation method of step 211, the utilization of Service Quality Management device is carried out calculation process to the KPI that receives and/or KQI and is obtained serving KQI information and (for example the time difference between fault time and recovery time is obtained failure recovery time, again a plurality of failure recovery times are averaged and obtain mean failure rate recovery time), store this service KQI information and be used for the user inquiring and the analyzing and processing of service quality afterwards.

Step 212, Service Quality Management device are analyzed service quality, concrete analytic process includes but not limited to: the performance clause among Analysis Service KQI information and the SLA, whether detect exists SLA unusual, be whether resulting service KQI information meets the standard of signing among the SLA, do not meet that then SLA is unusual, meet that then SLA is normal; If SLA is unusual, then the location is unusually from the service transmission network that provides with the net operation merchant, or own service flow process (purpose of location is in order to distinguish unusual person liable, can to use these information in the processes such as compensation, fault eliminating that break rules at QoS of customer); Trigger corresponding exception handling procedure if SLA is all right unusually according to the strategy of signing among the SLA.This exception handling procedure includes but not limited to: according to abnormal conditions, unusual to Virtual network operator equipment dispatch order, report, call exception handling procedure etc.If cause SLA to break rules unusually, the then deduction and exemption of chargeing, reparations and initiatively report to user's fault information etc. at the user.

The process that above-mentioned steps 208 is carried out for circulation to step 212, (it is corresponding with startup SLA services quality monitoring process to stop SLA services quality monitoring process when the Service Quality Management device need stop SLA services quality monitoring process, for example when finishing, service stops SLA services quality monitoring process, perhaps when recovering normal report, the custom system reporting service quality stops SLA services quality monitoring process, perhaps when the abnormality processing terminal procedure finishes, stop SLA service order observation process), carry out following steps 213～216 again.

Step 213～216, Service Quality Management device send the instruction that stops monitoring policy and arrive the performance strategy processor, comprise the SID of the monitoring policy that is stopped in this instruction; The performance strategy processor receives that the instruction back sends the instruction that stops to monitor to the involved performance detector of this monitoring policy, and the termination performance policy handler may discharges the shared computational resource of this monitoring policy (for example cpu resource, memory source, thread resources etc.) to the processing procedure of this monitoring policy; Described performance detector is received the monitoring that stops after the instruction that stops to monitor the primitive network performance parameter, returns to stop to monitor successful message to the performance strategy processor, and the performance strategy processor returns and stops to monitor successful message to the Service Quality Management device.

If the Service Quality Management device need be destroyed monitoring policy, for example, when not needing to continue to carry out this monitoring policy, then need to destroy this monitoring policy and (must stop this monitoring policy earlier for the long term monitoring strategy, destroy this monitoring policy again), then carry out following steps 217～218.

Step 217～218, Service Quality Management device send the instruction of destroying monitoring policy and arrive the performance strategy processor, the SID that comprises the monitoring policy of required destruction in this instruction, the monitoring policy that the performance strategy processor will need to destroy is deleted from the longer-term storage unit (for example hard disk and database) of self, and discharge all resources that this monitoring policy occupies, return after finishing and destroy success message to the Service Quality Management device.
