Embodiment
In order to the technical scheme and advantage that make the application are clearly understood, be described in more detail below in conjunction with the exemplary embodiment of accompanying drawing to the application, obviously, described embodiment is only a part of embodiment of the application, instead of all embodiments is exhaustive.And when not conflicting, the embodiment in this explanation and the feature in embodiment can be combined with each other.
Inventor notices in invention process:
At present, operator is confined to the passive monitoring to network equipment failure mostly to the monitoring of broadband network, lacks the monitoring of end-to-end QoS and initiatively ensures.Although have part specialized company (as keynote company) to provide evaluate and test service in short-term to the end-to-end of quality of service, but be all test and assess in short-term, problem-solving, lack end-to-end QoS monitoring means that is extensive, that continue, the quality of service reflecting general domestic consumer cannot be continued, cause operator to lack and the direction of network resource optimization and problem are initiatively prevented.
Therefore, in the urgent need to the broadband end-to-end QoS monitoring system that founds a family, realize that broadband networks is continued to carry out teleservice and experience monitoring.Inventor notices, router, as the entrance of domestic consumer's accessing to wide band network, can experience the end points of monitoring as teleservice.
Based on this, the embodiment of the present application proposes a kind of quality of service detection method and router, is described below.
Fig. 2 shows the schematic flow sheet that in the embodiment of the present application, quality of service detection method is implemented, and as shown in the figure, quality of service detection method can comprise the steps:
Step 201, router are that often kind of application generates operation layer probe requests thereby message according to TCP/IP application layer protocol;
The operation layer probe requests thereby message of generation is sent to ISP (ISP, Internet Service Provider) content source by step 202, router, and completes data according to default judgment mode analyzing service quality according to business;
Step 203, when quality of service result of detection exceeds pre-determined threshold, described router report and alarm information.
Broadband internet is based on ICP/IP protocol, and Fig. 3 shows the structural representation of ICP/IP protocol, and as shown in the figure, the quality of service detection method that the embodiment of the present application proposes can based on the automatic structural exploration message of ICP/IP protocol application layer.In the embodiment of the present application, consider that application layer protocol classification is various, and different application connection mechanisms is widely different, therefore, different detection mechanism can be adopted for often kind of application.
The operation layer probe requests thereby message that router can be generated automatically in the embodiment of the present application, periodically or be sent to ISP content source desirably, complete data (as business deadline, business datum amount etc.) by quality of service and carry out end-to-end experiences judge.
Described ISP content source can be edge content distributing network (CDN, Content DeliveryNetwork) node, convergence center CDN node or isp server.
In the specific implementation, ISP content source can be CDN layer edge C DN node, also can be the convergence center CDN node of CDN layer, can also be isp server, the embodiment of the present application be restricted this.
In the specific implementation, in advance to the experience effect setting reasonable interval thresholding of each business, when the result of detection of certain quality of service exceeds default reasonable threshold, then can think that network occurs abnormal.Pre-determined threshold can require to set flexibly according to O&M, and the application is not restricted this.
Now, router can generate warning information automatically, such as, when service response time, service rate exceed pre-determined threshold to operation maintenance personnel report and alarm, detection record also can also be reported operation maintenance personnel, so that operation maintenance personnel carry out reference analysis etc. simultaneously during report and alarm.
The embodiment of the present application provides a kind of quality of service detection method, the router held by family generates the message for business detection automatically according to TCP/IP application layer protocol, the visit data of the various application of Real-Time Monitoring, automatic analysis business key index wherein, timely understanding holds the end-to-end QoS of ISP content source from family, the timely report and alarm when there being abnormal conditions, aid operators Timeliness coverage network problem, carry out network resource optimization and problem initiatively prevention, strengthen broadband user to experience, improve carriers vie power.
In enforcement, described quality of service detection method may further include:
