Embodiment Construction

[0052] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0053] The Internet of Things system of the present invention allows the establishment of multiple M2M terminal message buffer queues, and the information of all M2M terminal message buffer queues is managed by a doubly linked list. Each queue corresponds to a kind of M2M terminal report message, and each queue can be used Memory + files are used to store the messages reported by M2M terminals. The system manages the memory usage block as a unit. The application and release of memory are all based on a single memory block, which effectively improves the memory utilization rate; the size of the cache file and the size of the memory block Consistent, when the message needs to be obtained from the file, it is processed by mapping the entire file into the memory, and when the message in the file is obtained again later, it is processed from the memo...

Abstract

The invention discloses a cache control method in an M2M system. The method comprises the following steps: the system creates an M2M (machine to machine) terminal message cache queue, and adds the generated M2M terminal message cache queue information into cache queue management information; according to the cache queue management information, the system stores a message reported by the M2M terminal into a corresponding M2M terminal message cache queue in a memory cache way and a file cache way, or extracts an M2M terminal message from a corresponding M2M terminal message cache queue. By applying the invention, when providing high efficient and unlimited cache space, a utilization rate of memory also can be raised simultaneously.

Description

technical field [0001] The invention relates to the application field of the Internet of Things, in particular to an Internet of Things system and a control method for buffering therein. Background technique [0002] With the rapid development of computer technology today, the Internet of Things is increasingly becoming a direction for future Internet development. In M2M (Internet of Things) applications, M2M servers are often connected to tens of thousands of terminals at the same time, and there are a large number of messages at the same time that require M2M Server processing. At this time, the M2M server cannot receive the next message after processing one message. This will cause the problem of message loss or blocking. Therefore, it is necessary to receive the message first, cache it, and then obtain the message from the cache for processing. [0003] In the traditional M2M server, there are memory caching and file caching for message caching. The memory caching can be...
