Control method for reliable controllable network architecture

Abstract

A controllable dependable network system structure and a control method thereof are disclosed, which realizes effective control of network resources and user behavior on the basis of current network structure hierarchy, the system structure has four layers like a decision layer, an observation layer, a resource layer and a controllable interface layer, wherein the controllable interface layer achieves the interaction between the current network system and the resource layer in a manner of protocol cross-layer, the resource layer provides the observation layer with a resource stream via the protocol of the controllable interface layer, the observation layer extracts properties from a dependability stream and a logic stream to provide a view with better consistence and observability for the decision layer; the decision layer, on the ground of the observable view and in terms of current situation of the system and the overall profit maximization, sets forth a control proposal which is provided for the network through the dependable interface layer, for the purpose of control; meanwhile, dependability of each component at this moment is given out to be provided for the observation layer via the dependable interface layer in a form of dependability stream.

Description

technical field [0001] The present invention relates to the field of network security and network management, specifically a credible and controllable network architecture and its control method, which are used to realize the predictable and manageable behavior of the network and its components and users, for the following A generation of trusted and controllable network provides infrastructure. It belongs to the field of network technology. Background technique [0002] In 1983, the International Standardization Organization (ISO: International Standardization Organization) formulated the Open System Interconnection (OSI: Open System Interconnection) reference model, which played an irreplaceable role in standardizing the computer network architecture. The TCP / IP protocol model originated from the network architecture and protocol standards developed by the U.S. Department of Defense for its ARPANET wide area network. The Internet based on it is currently the largest compu...

Problems solved by technology

[0020] Generally speaking, with the continuous development of new technologies, network systems are becoming more complex and heterogeneous, network anomalies and attack behaviors are becoming more and more diverse, and the requirements for service quality are constantly evolving. However, the above-mentioned architecture is either based on edge theory and non-connection-oriented design ideas, making the packet transmission path uncontrollable, or redesigning the existing network system architecture, costly
