Embodiment Construction

[0027] see figure 1 , the caching system of the cloud computing network of the present invention is deployed on each node of the cloud computing network, and the system includes:

[0028] The service module receives tasks sent by other nodes (including task types and task parameters), and records the types of tasks that local nodes can perform;

[0029] The assignment module assigns the tasks received by the local node to the local node for execution, or forwards them to other nodes;

[0030] A caching strategy module records caching strategies for various tasks (especially various tasks that local nodes can perform), and the caching strategy includes whether to cache and cache time;

[0031] The cache management module manages the cache size of the local node, searches for tasks in the cache of the local node, and saves the task to the cache of the local node.

[0032] see figure 2 , the caching method of cloud computing network of the present invention comprises the foll...

Abstract

The invention discloses a cache system for a cloud computing network, which is arranged on each node of the cloud computing network and comprises a service module for receiving tasks transmitted fromother nodes and recording the types of the tasks which can be executed by a local node; a distributing module for distributing the tasks received by the local node to the local node to execute the tasks or forwarding the tasks to other nodes; a caching strategy module for recording the caching policies of various tasks, wherein the caching policies comprise a caching decision and a caching time; and a caching management module for managing the cache size of the local node, searching the task in a cache of the local node, and storing the task to the cache of the local node. The invention also discloses a caching method for the cloud computing system. The cache system for the cloud computing network and the method thereof establish a local cache system of each node in the cloud computing network, also utilize the cache system of a CDN network, so that the cloud computing can be performed faster and more efficient world wide, avoid the probability of each node to execute the same task repeatedly and also reduce the utilization of a network bandwidth greatly.

Description

technical field [0001] The invention relates to a cache system of a computer network and a method thereof. Background technique [0002] Cloud Computing is the development of Distributed Computing, Parallel Computing and Grid Computing. Its basic principle is to distribute computing tasks to multiple computers through the network. The computer is called a node of the cloud computing network. [0003] In the existing cloud computing network, each node does not have a cache system, which means that the node may perform the same task repeatedly. For example, node A receives a "1+1" calculation task, node A completes the calculation task, and node A returns the calculation result. After a period of time, node A receives the "1+1" calculation task, node A completes the calculation task, and node A returns the calculation result. This is obviously a waste of resources on the cloud computing network. [0004] Using a browser to access the World Wide Web (WWW) is one of the most...
