Distributed cache system based on distributed virtual machine manager and working method thereof

Abstract

The invention relates to a distributed cache system based on a distributed virtual machine manager and a working method thereof; the system comprises a virtual machine used for carrying out inquiry according to cache request, a distributed virtual machine manager, a local memory block and a memory block on a remote machine; the virtual machine is used for inquiring the corresponding memory block according to the information in the cache request; if the memory block is the local memory block, the virtual machine directly takes the contents of the memory block out and returns the contents to the cache request; and the distributed virtual machine manager is used for shunting back the memory block on the remote machine to the local and returning the contents of the memory block to the cache request when the corresponding memory block is the memory block on the remote machine. Compared with the previous DHT application, in the invention, the application layer does not need to maintain complicated network protocol, spend a great deal of communication overhead and consider the problem of virus disseminating among different networks, therefore, the application layer is safer and more reliable.

Description

technical field [0001] The invention relates to a distributed virtual machine manager, in particular to a distributed cache (cache memory) system based on a distributed virtual machine manager and a working method thereof. Background technique [0002] With the development of network technology, the memory on a single machine is increasingly unable to meet the requested memory requirements, especially for the cache, the memory space is seriously insufficient. In this case, the caching strategy based on Distributed Hash Table (DHT) has become the mainstream of caching, so that more users can access a large amount of information stored on geographically distributed sites. [0003] DHT is introduced from the research of peer-to-peer network (Peer-to-Peer, referred to as P2P). P2P technology connects different computers in the network together, and can make full use of resources anywhere in the Internet and Web sites. The P2P system is autonomous, distributed, and dynamic, and...
