Method for automatically adjusting storage resources of servo system

Abstract

The invention relates to a method for automatically adjusting the storage resources of a servo system. The method is applied to a servo system and the servo system comprises a plurality of distributors, and each of the distributors corresponds to a plurality of network servers. When the network server to which one of the distributors belongs bears too much load, the distributor turns into a request distributor and other distributors are turned into distributors to be scheduled; the request distributor sends an enquiry signal to the distributors to be scheduled; if the request distributor receives a response signal sent by one of the distributors to be scheduled, the request distributor specifies the distributor to be scheduled as a scheduled distributor and retransmits a data request signal to the scheduled distributor; if the request distributor receives a server data transmitted by the schedule distributor once again, the request distributor sets the network server to which the serer data corresponds as the network server to which the request distributor belongs so as to reach the goal of automatically adjusting the storage resources of the servo system.

Description

technical field [0001] The present invention relates to a method for automatically adjusting the storage resources of a servo system, especially a method including a plurality of allocators, and when the load of a plurality of network servers corresponding to one of the allocators is too large, the network servers corresponding to the other allocators can be allocated The web server is set to the web server to which this distributor belongs. Background technique [0002] Today is an era of electronic information and the vigorous development of the information industry. The transmission speed and communication mode of real-time information are diversified due to the continuous innovation of various wireless communication devices, electronic products and network transmission technologies. The rapid popularization of the network and the popularity of various portable electronic products have made wireless communication and network services, which were out of reach in the past, ...

Problems solved by technology

[0004] In order to avoid the abnormal situation of the server due to various reasons, which will lead to data access or network service interruption, that is, some operators have developed a server system with multiple hosts. This kind of server system can greatly increase the stability of operation. When there is a When one host fails abnormally, other hosts can support each other to avoid the situation that a single server cannot provide services due to damage, so that the client only feels a few seconds of delay when receiving the response, greatly reducing the interruption of the servo system The service time can also prevent the data read or transmitted in the server system and the client from being damaged or lost. However, although the known multi-host server systems have the aforementioned advantages, they all need to face the problem of load imbalance, that is, Because the transmission traffic is concentrated on a few servers, the system service is delayed or abnormal, so that the client cannot get a quick response after requesting the service

[0005] In response to this situation, some operators adopt the method of load balancing (Load Balance) to solve the problem of unbalanced load, and the current general server system uses a domain name server (Domain Name Server) to take turns (Round-Robin) method distributes traffic to multiple back-end servers, that is, sequentially transmits data transmission traffic to these servers respectively. However, the biggest deficiency of this method is that the domain name server (DNS) cannot know the back-end Whether these servers are overloaded or unable to provide services, even if some servers have been overloaded or have entered a paralyzed state, the zone name server will continue to transmit data to them, so this static round-robin (Round-Robin) It cannot cope with dynamic network traffic changes. Therefore, if the load of the domain name server (DNS) can be dynamically adjusted to reduce the load of these back-end servers, it will be welcomed by network service providers and users.
