Problems solved by technology
[0004] Due to network and disk IO service time jitter and queuing time and other factors, there will be a certain delay in each stage of the request. If different requests generated by the same application are processed according to the principle of FCFS, when a request in a certain When the delay of the first stage is high, the delay of the request in the subsequent stages will be higher and higher, forming a long tail delay (long tail latency), resulting in an increase in the delay fluctuation between different requests of the application, and the application performance is adversely affected

Embodiment Construction
[0026] The technical solution in this application will be described below with reference to the accompanying drawings.
[0027] figure 1 is a schematic flowchart of a method for processing requests provided by this application. Such as figure 1 As shown, the method 100 includes:
[0028] S110. The receiving end receives a first request and a second request, wherein the first request is a request sent by the first sending end at the first sending moment, and the second request is a request sent by the first sending end at the second sending time. The requests sent at any time, the first request and the second request are different requests generated by the first application program.
[0029] S120. The receiving end acquires the first sending moment and the second sending moment.
[0030] S130, the receiving end processes the first request and the second request according to the timing of the first sending moment and the second sending moment, wherein the first sending momen...

The invention discloses a request processing method and device. The method comprises the steps that a receiving end receives a first request and a second request, wherein the first request is a request sent by a first sending end at a first sending time point, the second request is a request sent by the first sending end at a second sending time point, and the first request and the second requestare different requests generated by a first application; the receiving end acquires the first sending time point and the second sending time point; the receiving end processes the first request and the second request according to a time sequence of the first sending time point and the second sending time point, wherein the time sequence of the first sending time point and the second sending time point is identical to a processing sequence of the first request and the second request. Delay fluctuations of different requests generated by the same application are reduced, and the computer networkis more stable.
Description
technical field [0001] The present application relates to the field of computers, and in particular to a method and device for processing requests. Background technique [0002] In a computer network, for example, in a distributed storage system, the input / output (input / output, IO) path of a request includes multiple stages such as network and storage, and each stage has a request queue. Requests are processed in a certain order. [0003] At present, when the server receives different requests, it processes the requests according to the principle of first come first service (FCFS), that is, the server records the time when the request arrives at the server, and prioritizes the earlier request when it arrives at the server . [0004] Due to network and disk IO service time jitter and queuing time and other factors, there will be a certain delay in each stage of the request. If different requests generated by the same application are processed according to the principle of F...
