Abstract
The invention discloses a kind of data download methods of Internet of Things, it is used for any internet of things equipment and things-internet gateway for having certain data upload and data download requirements, the present invention provides between the things-internet gateway of different function and internet of things equipment, the solution annual reporting law of the data transmission of low delay low cost between the things-internet gateway and internet of things equipment of the production of identical function different vendor.The transparent compatibility of this programme application layer service protocol, application layer developer need not change application program, and all things-internet gateway and internet of things equipment all automatic adaptations using this agreement reduce data traffic, to reduce delay, reduce cost.Moreover, this programme while compatible existing network, are compatible with automatically using the things-internet gateway and internet of things equipment of this agreement and the things-internet gateway and internet of things equipment of this unused agreement.Compare with other Internet of Things data download algorithms, of the invention has automatic compatibility, deployment to be easy, feature of low cost.
Description
Technical field
The present invention relates to a kind of technology of Internet of things, the data download method of specifically a kind of Internet of Things.
Background technology
Internet of Things is the important component of generation information technology, and the important development stage in " informationization " epoch.
Its English name is：“Internet of things(IoT)”.As its name suggests, Internet of Things is exactly the connected internet of object object.This
There is two layers of meaning：First, the core of Internet of Things and basis are still internet, it is extension and extension on Internet basic
Network；Second, its user terminal extends and extends between any article and article, information exchange and communication are carried out, that is,
Object object mutually ceases.Internet of Things communicates cognition technology by Intellisense, identification technology and general fit calculation etc., is widely used in network
In fusion, also therefore it is referred to as the third wave that world information industry develops after computer, internet.Internet of Things is mutual
The application extension of networking, rather than Internet of Things is network, Internet of Things is business and application.Therefore, application innovation is object
The core of networking development is the soul of Internet of Things development using user experience as the innovation 2.0 of core.
The download transmission of existing Internet of Things frequent design data in use, and existing method for down loading is compatible
Difference, transmission speed are slow, and delay rate is higher.
Invention content
The purpose of the present invention is to provide a kind of data download methods of Internet of Things, to solve to propose in above-mentioned background technology
The problem of.
To achieve the above object, the present invention provides the following technical solutions：
A kind of data download method of Internet of Things, includes the following steps：
S1, certain internet-of-things terminal carry out TCP by other internet-of-things terminals or things-internet gateway to certain content server
Three-way handshake；
S2, internet-of-things terminal start to upload data or start downloading data by intermediate node；
S3, data flow flow through intermediate node, and intermediate node carries out data deduplication, with a part of data flow specified in advance
Cryptographic Hash is that index establishes caching；
S4, all intermediate nodes all first calculate a part of data flow specified in advance before forwarding TCP to next node
Cryptographic Hash；
If S5, inquiring, which terminates TCP connection with subsequent intermediate nodes；
The express delivery of S6, identical " XY " value are sorted to same position；
The data of caching are all sent to start node by S7, intermediate node；
S8, start node close TCP connection after harvesting data.
As a further solution of the present invention：Intermediate node in the step S2 be specifically other internet-of-things terminals or
Things-internet gateway.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention has certain data upload and data for any
The internet of things equipment and things-internet gateway of downloading request, the present invention provides the things-internet gateway of different function and internet of things equipment
Between, the data transmission of low delay low cost between the things-internet gateway and internet of things equipment of the production of identical function different vendor
Solve annual reporting law.The transparent compatibility of this programme application layer service protocol, application layer developer need not change application program, all to make
With things-internet gateway and internet of things equipment all automatic adaptations of this agreement, reduce data traffic, to reduce delay, reduce at
This.Moreover, this programme while compatible existing network, use the things-internet gateway and internet of things equipment of this agreement and this association are not used
The things-internet gateway and internet of things equipment of view are compatible with automatically.Compare with other Internet of Things data download algorithms, of the invention has certainly
Dynamic compatibility, deployment are easy, feature of low cost.
Specific implementation mode
The following is a clear and complete description of the technical scheme in the embodiments of the invention, it is clear that described embodiment
Only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, the common skill in this field
The every other embodiment that art personnel are obtained without making creative work belongs to the model that the present invention protects
It encloses.
In the embodiment of the present invention, a kind of data download method of Internet of Things includes the following steps：
S1, certain internet-of-things terminal carry out TCP by other internet-of-things terminals or things-internet gateway to certain content server
Three-way handshake；
S2, internet-of-things terminal start to upload data or start downloading data by intermediate node；
S3, data flow flow through intermediate node, and intermediate node carries out data deduplication, with a part of data flow specified in advance
Cryptographic Hash is that index establishes caching；
S4, all intermediate nodes all first calculate a part of data flow specified in advance before forwarding TCP to next node
Cryptographic Hash；
If S5, inquiring, which terminates TCP connection with subsequent intermediate nodes；
The express delivery of S6, identical " XY " value are sorted to same position；
The data of caching are all sent to start node by S7, intermediate node；
S8, start node close TCP connection after harvesting data.
Wherein：Intermediate node in step S2 is specifically other internet-of-things terminals or things-internet gateway.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
Profit requires rather than above description limits, it is intended that all by what is fallen within the meaning and scope of the equivalent requirements of the claims
Variation is included within the present invention.
