Problems solved by technology

[0004] figure 1 It is a flowchart of a request congestion overload processing method of a cluster network in the prior art. When a client service request is received, if the number of client requests reaches or exceeds the scheduling system's own processing capacity, the scheduling system processes Timeout causes some or even all of the network to be in a deadlock state, and eventually the effective throughput of the network is close to zero.

Abstract

The invention provides a cluster network's request congestion and overload processing method and a system. In the method, a comparison is made first between the number of requests from users' terminals and the allowed upper limit on the requests pre-set according to the processing ability of each scheduling node in the cluster network. When the number of requests from users' terminals reaches or goes beyond the upper limit, the system randomly denies the requests. When there are fewer requests from the users' terminals than the upper limit, a further comparison is to be made between the current load state value of the cluster network and the pre-set load threshold value wherein the pre-set load threshold value is no greater than the maximum load capacity value of the network. And if the current load value touches or goes beyond the preset load threshold value, then the system reduces the responding ability of the cluster network to requests. The invention also provides a cluster network's request congestion and overload processing system. For the multiple layers of overload protections at scheduling nodes, the system ensures that a cluster network operates well.

Description

technical field [0001] The embodiments of the present disclosure relate to the field of communication technologies, and in particular, to a method for processing request congestion overload of a cluster network. Background technique [0002] A cluster server consists of several servers interconnected by an input / output system. These servers are connected to storage media and managed by distributed resource management software (DRM). The main application of server cluster technology is the function of network load balancing. Network Load Balancing provides high availability and scalability for servers using a cluster of two or more host computers working together. [0003] The basic idea of ​​content distribution network is to avoid as far as possible the bottlenecks and links on the Internet that may affect the speed and stability of data transmission, so as to make content transmission faster and more stable. By placing node servers all over the network to form a layer o...
