A generalized unified representation method and system for satellite network resources

Abstract

The invention provides a generalized method and system for unified characterization of satellite network resources. The method comprises the following steps: firstly, identifying to-be-characterized satellite network resources, and defining identity identifiers, resource attribution, spatial coordinates and relative movement speeds of the resources; secondly, describing local / partial characteristics of the to-be-characterized satellite network resources, and decomposing inherent attributes or attribute capabilities of the resources; describing the states of the decomposed attributes; reflecting the degree of mutual restriction between internal attributes of the resources through the definition of relevance parameters of the internal attributes; and finally, describing the relationship between the to-be-characterized satellite network resources and other resources of the same type in the network from the following three aspects: the attribute connection capability, the collaboration capability and concurrent available time periods of the resources of the same type. By adoption of the method, the problem of unified characterization of multi-dimensional satellite network resources issolved, the description of the inherent attributes of the resources is more accurate and real, and the problem of collaborative description of decentralized and autonomous network resources of the same type in the description of network characteristics is solved.

Description

technical field [0001] The invention relates to a generalized unified representation method and system for satellite network resources, belonging to the communication field. Background technique [0002] There are a large number of heterogeneous and discrete systems in the space-based information network. The network resources in these systems have a long construction cycle and high cost, and each resource is very precious. However, in practical applications, various resources of different systems are scattered in various places in terms of spatial distribution, lack of a unified description mechanism in terms of resource description, and manage independently and independently at the level of resource management. The above-mentioned reasons have caused a great waste of space-based information network resources, and it is difficult to manage and schedule the entire network resources uniformly from the system level, so as to realize efficient management and full utilization of...

Problems solved by technology

The network resource description method based on RSL (Resource Specification Language, resource description language) mainly focuses on the description of resource requests and computing resources, and cannot describe other resources, and the scope of use is too small; the network based on RDF (Resource Description Framework, resource description framework) The resource description method provides a means to describe the nature of a certain type of object, but only defines a resource description framework, which itself does not provide a special mechanism to describe the nature of resources and resources; based on WSDL (Web Services Description Language, network service description language) network resource description method, does not support the semantic description of resources, is only suitable for describing service access interfaces of coarse-grained dynamic systems, and is not suitable for describing grid resources

In addition, WSDL neither pays attention to the restrictive relationship between different attributes of specific resources, nor does it pay attention to the degree of association and influence relationship between different resource owners; the cognitive network resource description method only considers the local resource description of a point or a region, and does not Considering the relationship between local resources and other similar resources in the network, it cannot solve the problem of unified description of similar resources in different networks
