Embodiment
The invention will be further described below in conjunction with specific embodiments and the drawings, but should not limit protection scope of the present invention with this.
Present embodiment returns the source side method in order and mainly may further comprise the steps:
Receive user's request, for example the fringe node server receives a plurality of user's requests from client;
If this user's request does not need Hui Yuan, then directly it is handled by the fringe node server;
If this user's request needs Hui Yuan, judge then whether server current processing load in source station reaches default limit value;
If this source station server does not reach default being limited to, then by the source station server it is handled;
If server current processing load in described source station reaches this default limit value, then this user is asked to sort wait;
When the processing load of described source station server was lower than this default limit value, described source station server asked preferentially to handle to ordering user at first.
Below with reference to Fig. 2, in conjunction with an example this time source side method is elaborated.
At the S21 place, client is sent a plurality of user's requests, and these a plurality of user's requests can be the HTTP requests from a plurality of different clients.
At the S22 place, the fringe node server receives request.
At the S23 place, judge whether the client requests that receives needs Hui Yuan.For example, judge whether client requests resource pointed needs the access originator site server to obtain.
If this client requests does not need Hui Yuan, for example the resource of client requests sensing has corresponding cache file in the fringe node server, then goes to S24, is responded by the fringe node server process, for example, the fringe node server directly returns to user side with the file of local cache.
If this client requests needs Hui Yuan, then advance to S25, judge whether server current processing load in source station reaches default limit value.This limit value can be predefined according to the actual treatment ability of source station server, for example the client requests quantity that can handle concomitantly simultaneously of source station server.
If server current processing load in source station does not reach this limit value as yet, then go to S28, handle this client requests by the source station processor, for example inquire about the resource that this client requests is pointed to, and advance to S24, transfer to the fringe node server and respond to client.
If server current processing load in source station has reached this limit value, then advance to S26, time order and function rank order according to client requests is waited for, for example, user's request can be added in the waiting list according to the time order and function order, time client requests early comes position more preceding in the waiting list, the position after later client requests of time comes in the waiting list.
Advance to S27 afterwards, judge whether the source station server can receive request, also be whether server current processing load in source station is less than this limit value, if words, then take out the client requests of waiting list head of the queue, and and then advance to S28, by the source station server client requests of taking out is handled, and result returned to the fringe node server, the fringe node server returns to response the user side that sends this client requests again; If handle load not yet less than this limit value, then return S26, continue to wait for.
In addition, be lower than limit value and current waiting list when empty at the processing of source station server load, can ask new user directly to handle, and not need to wait in line.
Need to prove, according to the time order and function order user is asked to sort wait in the above-mentioned example, but be not limited to this, for example can also come the user is asked to sort wait according to the priority of client requests, before the higher client requests of priority comes, can obtain priority treatment.
Fig. 3 shows the structured flowchart that returns in order source apparatus in content distributing network of present embodiment, comprising: user interface section 31, judging unit 32, sequencing unit 33, first processing unit 34, second processing unit 35, the 3rd processing unit 36, the are managed unit 37 everywhere.
Wherein, user interface section 31 is used for receiving the user's request from client.Whether judging unit 32 needs Hui Yuan in this client requests, and judges when needs go back to the source whether server current processing load in source station has reached default limit value.If this user request does not need Hui Yuan, then second processing unit 35 is transferred to the fringe node server with user's request and is handled and response results is returned to client.
If server current processing load in source station does not reach default limit value, then the 3rd processing unit 36 these source station servers of visit obtain required data, for example the resource data of client requests sensing.If the current processing of source station server load has reached default limit value, then 33 pairs of users' requests of sequencing unit wait of sorting for example can be according to the wait of sorting of time order and function order.When the processing load of source station server is lower than default limit value, to sort at first user asks preferentially to give the source station server and handles first processing unit 34, the source station server is transferred to the fringe node server with result, and further returns to the client by the fringe node server.If the processing of source station server load is lower than user's request (for example waiting list is for empty) that default limit value and current ordering are waited for, then new user is asked directly to handle and need not ordering and wait for.
