Description
Technical field
The present invention relates to data exception recovery technology, particularly relate to the method and apparatus that content distributing network (CDN) null response recovers.
Background technology
The basic thought of the null response recovery technology of content-based distributing network is, user asks the file of source head response not with Cache-Control:no-cache or no-store or private or max-age=0 using CDN, during static file (hereinafter referred to as static file) of i.e. non-caching, when source server do not exist the file of request or source server low-response or CDN fringe node have problem to source server thus cause the file of request to be null response time, such as picture file shows red fork, CDN fringe node should be able to Timeliness coverage file abnormal, recover as early as possible, the influence time of null response is dropped to the shortest.
The realization of current null response recovery scheme is as shown in Figure 1:
Step S11: when the static file that user asks source station newly to be issued or buffer memory static file out of date, CDN fringe node returns source request;
Step S12: judge back any platform source server by the monitoring of node source station, and send request to source server;
Step S13: source server responds the file of asking to CDN fringe node;
The file that source server responds is returned to end user by step S14:CDN fringe node;
No matter whether this file of step S15:CDN fringe node buffer memory be null response, now do not judge whether demand file is null response.
Step S16: if null response file, then will wait user to ask this file and CDN fringe node judges that the after date that is cached of this file returns source request again, and when source server provides normal response, null response just recovers, and fork as red in picture recovers normal display.
There is following drawback in existing null response recovery scheme: whether the static file of no matter asking is null response, unified according to cache module cache file.If there is null response, then only have and again ask when being cached after date Hui Yuan, when source server provides normal response, null response just recovers, this recovery process, can not realize fast recovery, during this period of time not out of date at judgement buffer memory, all what return the request of this file is all the situation of null response, extends the time of fault, exacerbates the impact of fault.Such as use the game website of CDN, the frequency gets higher of null response situation is there is after redaction upgrading, the problem that the null response that has been exactly buffer memory causes, if the file cache time of this null response is i.e. 1 day, then after at least will waiting 1 day, buffer memory is expired and have client to ask this file just likely to recover normal.
