Abstract
The invention provides a method for achieving an object-oriented data communication protocol structure. The communication protocol structure comprises a protocol head, data content and a protocol tail; the basic structure of the data content is objects, the data content is composed of at least one top object structure in series connection, and the top objective structure consists of at least one bottom object structure in series connection. The method has the advantages of being simple in structure, easy to automatically build and analyze; high in generality, wherein new requirements can be compatible as long as data object types and parameter object types are added; and good in expansibility, wherein types, numbers and lengths of top data objects and bottom parameter objects are variable, and the change does not affect the protocol structure, for the completed protocol building and analytic procedures, only data definition is required to be added, and no change is required for building and analytic procedures.
Description
Technical field
The present invention relates to computer communication technology, specifically, relate to a kind of implementation method of OO data communication protocol structure.
Background technology
Communication protocol (communications protocol) is meant both sides' entity completion communication or service mandatory rule of institute and agreement.Protocol definition the form that uses of data cell, information that information unit should comprise and implication, connected mode, the sequential that information is sent and received, thus guarantee that data successfully are sent to definite place in the network.
In compunication, communication protocol is used to realize the standard between the computer and network connection that if network does not have the uniform communication agreement, the information transmission between the computer just can't be discerned.Communication protocol is meant the rule of communication that communication parties is arranged in advance, can be interpreted as simply to carry out the employed common language of mutual session between each computer.Two computers when communicating, the communication protocol that must use.
1) most at present communication protocols all are the structuring agreements, and every kind of agreement has concrete structure, and different environment needs different protocol, and inconvenience makes up automatically and resolves, and versatility is not strong.
2) in monitoring management system, need continue to increase the novel device monitoring, data type is changeable.Use general structuring agreement, a kind of equipment of every increase or data type will increase one or more fields, and it is chaotic repeatedly to expand the back structure, and protocol construction is bigger with the parsing programing change simultaneously.
3) Object-oriented Technique is applied in the design of protocol, can make up the good agreement of autgmentability.
Summary of the invention
The objective of the invention is to design a kind of structure and parsing, strong, OO data communication protocol structure of autgmentability of being easy to.
A kind of implementation method of OO data communication protocol structure, said comnnnication protocol structure are by protocol header, and data content and agreement tail are formed; The basic structure of said data content is object, and data content is composed in series by at least one high-rise object structure, and said high-rise object structure is composed in series by at least one underlying object structure.
Preferably, said high-rise object structure is a data object, and data object comprises data object type, data object ID, data object data length and data object parameter object sequence.
Preferably, said underlying object structure is a parameter object, and parameter object comprises parameter type, number of parameters, parameter unit length and parameter value.
Preferably, said protocol header comprises agreement name, protocol version, type of message, protocol data length and other agreement parameters; Said agreement tail comprises check code and other agreement parameters.
Preferably, when said comnnnication protocol structure is used, can change protocol header and agreement tail as required under varying environment.
Preferably, the data content of said comnnnication protocol structure can make up and resolve automatically, and not restricting data content-length and size.
The present invention has following characteristics:
Simple in structure, make up automatically easily and resolve.
Highly versatile only needs increase data object type, parameter object type to get final product compatible new demand.
Favorable expandability; The high-rise data object and its type of parameter object, number, the length of bottom all are variable, and this variation does not influence the structure of agreement, concerning the protocol construction and analysis program accomplished; Only need to increase data definition, structure and process of analysis do not need to change.
Description of drawings

Embodiment
Below in conjunction with description of drawings embodiment of the present invention.
1) in concrete environment, confirms protocol header and agreement tail by general structuring protocol definition mode and real needs own.
Protocol header generally comprises agreement name, protocol version, type of message, protocol data length and other agreement parameter.
The agreement tail generally comprises check code and other agreement parameter.
Other parameter can be added as required.
2) confirm the high-level structure data object of protocol data content.
The data that need comprise which equipment in the specified data content are data object with these device abstracts, give the object type numbering in order.
3) confirm the fabric parameter object of protocol data content.
Which data that need comprise equipment in the specified data content, like concrete parameter such as size, position, electric weight, temperature, each parameter is abstract to be parameter object, gives the object type numbering in order.
4) according to actual transmissions content specified data content.
To each high level data object, fill its bottom parameter object value successively, type, numerical value number, unit length, the parameter value sequence of parameter object is set.
The type of padding data object, ID, total length.
5) confirm item relevant in protocol header, the agreement tail according to data content with data content.
Claims (6)
