Link information in phase；When the hop count being triggered is less than default hop count threshold value, does not execute acquisition Service Instance and exist
Link information in one detection cycle.In an embodiment of the present invention, preset the time, for example, be 1 minute or 30s etc.,
In this time, judge whether the request number of times triggering this Service Instance reaches certain value, for example, be 200 or 300, reaching
When, enter detection cycle, obtain link information in a detection cycle for the Service Instance.Preferably, set the service of detection
Classification, is only monitored to the link information of this service type and records, and to other classes outside the service type of this setting
It is not counted in the link information in detection cycle.
In order to preferably describe the embodiment of the present invention, with reference to Fig. 8, it is client and service end service request framework, in inspection
In the survey cycle, if the break links of Service Instance or Service Instance time-out reach predetermined threshold values, OSP Proxy (OSP
Agency) will triggering fusing mechanism, this Service Instance will not forwarded the request to by upper OSP in follow-up OSP Proxy special time
After service fusing, after certain recovery duration, the request access allowing a small amount of is blown Proxy by OSP Proxy
Service.If Service Instance is again correct responded, OSP Proxy recovers the normal access of service, if Service Instance is still no
Method correctly responds, then OSP Proxy be spaced again in the specific time not forward the request to this Service Instance will be upper.Fusing mechanism
Control on the access interface of service；Fusing mechanism acquiescence is to close, such as need to be related using then configuring in configuration center
Parameter, these parameters are all dynamically to change, and OSP Proxy need not be restarted；The configuration parameter of configuration center is based on clothes
Business rank, multiple Service Instances are shared, and multiple interfaces are shared；OSP Proxy needs to report the blown state for Service Instance,
Mercury route can know the fusing situation of the OSP Proxy of correlation when checking service
If the instance Service Instance error rate selecting from Available Instances available service example reaches molten
Disconnected strategy, then move on to this Instance inside CircuitBreak Instances fusing example；System Back-end is to each
CircuitBreak Instance has a Scheduler scheduler program triggering that it is moved on to Half-Open Instance
Half disconnects inside example；If the Instance of Half-Open state successfully calls, put back in Available Instance
Face.In the Service Instances processing procedure of Half-Open state, need to consider concurrent problem, such as concurrent invocation
When, one is called successfully, a malloc failure malloc.Specifically, with reference to Fig. 9, as the instance3 of ServiceB server B
There is larger error rate in Service Instance 3, reach fusing needs, then instance3 is fused, do not affect the tune of Client client
With.After the Instance3 that fused, because ServiceB is only left Instance1 Service Instance 1, Instance2 Service Instance
2, then pressure can increase, now need to be alerted, to avoid avalanche effect；If introduce Docker application engine container later
After change, can dynamically increase Instace4 Service Instance 4 to alleviate pressure, isolation Instance3 is to interrogate topic simultaneously.
These are only the preferred embodiments of the present invention, not thereby limit the present invention the scope of the claims, every using this
Equivalent structure or equivalent flow conversion that bright specification and accompanying drawing content are made, or directly or indirectly it is used in other related skills
Art field, is included within the scope of the present invention.
