Description
Technical field
The present invention relates to a kind of unitized satellite network resources Unified Characterization method and system, belong to the communications field.
Background technology
There is a large amount of isomery discrete parts in space information network, the network resource building cycle in these systems
It is long, of high cost, all seem precious per portion resource.But in practical applications, all kinds of resources of different system are in space point
It is scattered in terms of cloth that unified description mechanism is throughout short of in terms of resource description, do things in his own way, independently in resource management aspect
Management.Above-mentioned several respects reason causes the significant wastage of space information network resource, it is difficult to from system level to the whole network resource
Unified management and scheduling are carried out, so as to fulfill efficiently managing and making full use of to satellite network resources.
Satellite network integrally shows the characteristics of wide area is distributed, is various informative, isomery is autonomous, including：Antenna, wave beam, frequency
The different resource type such as spectrum, power, transponder, computing, storage, is related to multiple dimensions such as spatial domain, frequency domain, time domain.Satellite network
The resource construction cycle is long, is difficult to rapid, high volume extension, and Internet resources Unified Characterization is to realize that difference is discrete different in satellite network
The basis with allotment is efficiently managed in construction system resource set, there is high researching value.
Most representational resource description method mainly includes four kinds in ground network at present.Based on RSL (Resource
Specification Language, resource specification language) Internet resources method is described, mainly bias toward to resource request and
The description of computing resource, it is impossible to describe other resources, use scope is too small；Based on RDF (Resource Description
Framework, Resource Description Framework) Internet resources method is described, provide hand to describe certain class object with which kind of property
Section, but a resource description framework is only defined, itself does not provide special mechanism to describe between resource and resource
Property；Internet resources based on WSDL (Web Services Description Language, web services definition language) are retouched
Method is stated, does not support the semantic description of resource, is only suitable for describing the service access interface of the dynamical system of coarseness, is not suitable for
Gridding resource is described.In addition, WSDL had both been not concerned with the restricting relation between specific resources different attribute, different moneys are also not concerned with
Correlation degree and influence relation between the owner of source；Cognitive network resource describes method, only accounts for a little or region
Local resource describes, and does not account for the relation of other similar resources of Local resource and network, can not solve the similar money of heterogeneous networks
The Unify legislation problem in source.
The content of the invention
