Description

The method and device of real standing state operation in a kind of stateless procotol

Technical field

The present invention relates to real standing state in internet of things field, more particularly to a kind of stateless procotol The method and device of operation.

Background technology

Resource can be defined as one it is can directly accessing, stand-alone development, can dispose, it is manageable With maintainable software component, it supports specific data.Internet of Things resourceoriented framework (ROA) is Internet of Things transmits the soft of (Representational State Transfer, REST) style based on declarative state Part framework, the resource in environment of internet of things can be certain ability of certain terminal unit, terminal unit or Person's platform or certain ability of application.In towards ROA, data exchange is carried out centered on resource Operation, resource has common mode of operation, i.e. REST modes, and REST design packet contains several fundamental characteristics, One of basic feature：Stateless (Statelessness), i.e. each request to resource are (such as：HTTP Request) all it is isolated, do not rely on the request before or after it.But as the actual demand of real world, Do not ensure that each operation is independent, but exist or front or rear association, with reference to following several fields Scape.

Application scenarios one：

When there are two or more application terminals to issue query statement to same terminal unit simultaneously, inquire about Instruction needs to change the setting of terminal unit, terminal unit before inquiry operation is performed, according to application terminal Query statement perform certain arrange operation, when query statement perform after the completion of, terminal is recovered again in application terminal Equipment is to original setting.In this process, the application terminal for interacting needs and terminal unit Complete conversation procedure is set up, that is, is arranged -->Inquiry -->Recover, need serially to connect in a conversation procedure It is continuous to complete.

Application scenarios two：

Internet of Things radio equipment to machine agreement (Wireless Machine to Machine Protocol, WMMP) in protocol communication, multiple requests and response can constitute a complete session.In such cases, When application data packet length is more than one message inclusion greatest length of Internet, it may appear that many bag dispositions, Several situations can be divided:

Request bag subpackage.I.e. in the session of a WMMP communication process, requesting party has a data to ask Bag is asked to need transmission, answer party to receive after the request, the packet size of the response of return exceedes message inclusion Greatest length.Now, answer party will send data subpackage in the form of many bags this response to requesting party, Requesting party then sends a new request after each subpackage is received, to ask next subpackage, until receiving most Latter subpackage.

Response bag subpackage.I.e. in the session of a WMMP communication process, the request bag data of requesting party Bag size exceedes message inclusion.Now requesting party is sent to answer party with many packet modes and sends data subpackage, should The side of answering is received after subpackage, returns the subpackage response, and requesting party receives and next subpackage is sent after subpackage response, directly To last subpackage；The response message that answer party receives all subpackages and produces after processing is less than message inclusion Greatest length, now returns response bag；

Request-reply subpackage.This kind of mode is the combination of above both of which.

In former case, a session must be complete, and otherwise communicating pair is invalid regarding whole process, if During session communication, when producing subpackage or subpackage response loss, then retransmitted by requesting party and asked.

Application scenarios three：

Server is connected with sending client and receiving client based on stateless procotol, in server At least two session nodes, session node and two client phases are set up in the session table of simulation articulamentum Correspondence；Send client and send solicited message to server, the solicited message is objective comprising reception is ready for sending The exchange data at family end；Above-mentioned exchange data are kept in the corresponding session node of reception client by server； Receive client and send solicited message to server, server determines the corresponding session node of transmission client, Determine from the session table of simulation articulamentum and obtain at session node temporary exchange data, replying Above-mentioned exchange data are carried in information.During the connection of stateless procotol can be solved, the behaviour of real standing state Make.But if multiple client to same reception client sends message, or multiple client to same It is individual to receive the operation that client sends exclusive resource, such as, perform an exclusive inquiry operation, the scene Cannot solve.

It should be noted that " Internet of Things ", i.e., by RF identification (RFID), infrared inductor, the whole world The information sensing equipment such as alignment system, laser scanner, by the agreement of agreement, any article and the Internet Couple together, enter row information and exchange and communicate, to realize Weigh sensor, positioning, tracking, monitoring and manage The network of reason.
