Service request processing method and device

Abstract

The invention discloses a method and device for processing a service request, and belongs to the technical field of data transmission. The method comprises the steps that a first cache server receivesa service request of a user terminal and queries a local load state; if the first cache server is in the overload state, determining a second cache server according to the load state of a standby cache server; and the first cache server triggers the second cache server to obtain the service request, so that the second cache server processes the service request. By adopting the invention, the loadpressure of the machine in an overload state can be relieved in time, and the influence of machine overload on the business service quality can be reduced.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a method and device for processing service requests. Background technique [0002] With the continuous development of Internet technology, the network environment is becoming more and more complex, the number of users is increasing, and the quality requirements of network access are also getting higher and higher. In order to improve user experience and competitiveness, major network operators will deploy a large number of cache servers in their network architecture or choose to cooperate with cloud service providers to achieve accelerated network access through cache servers. [0003] In the above process, the service request sent by the user terminal can be transmitted to the redirection server first, and the redirection server can distribute the received service request according to the preset redirection strategy (such as redirecting according to URL or file name) ...

AI Technical Summary

Problems solved by technology

When a cache server is overloaded, on the one hand, due to the lack of real-time detection, if the cache server is overloaded, it will take a long time (3-5 minutes) for the redirect server to perceive it. Before, the user's business request will still be redirected to the overloaded cache server, which will affect the response efficiency of the business request; on the other hand, if the user terminal establishes a TCP long connection with the cache server, the user terminal will Based on the TCP connection, business requests are continuously transmitted to the cache server, and these business requests cannot be separated. When the cache server is overloaded, these business requests will not be responded in a timely and fast manner, and the user experience is poor.
