Method for controlling centralized resources in domain

Abstract

The invention discloses a method for controlling centralized resources in a domain. The method is characterized in that centralized control nodes are arranged in a network autonomous domain; underlayer network resources are used for reporting network resource status information to the control nodes; and the control nodes are used for making decision based on the status information and sending back the decision-making result to the underlayer device resources to conduct so as to form a closed loop control. The method can reduce the burden on a network router, improve the extendibility of the network, and reduce loads controlled by the resources in the domain to speed up the control convergence rate of the resources in the domain.

Description

technical field [0001] The invention belongs to the field of network technology, relates to the field of network management, and specifically relates to a resource control method for realizing effective management and control of intra-domain network resources. 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. Subsequently, the U.S. Department of Defense developed the network architecture and protocol standard TCP / IP protocol model for its ARPANET wide area network, and the INTERNET established on the basis of it is currently the largest computer network in the world. Because of the wide use of INTERNET, TCP / IP IP became the de facto Internet architecture standard. TCP / IP adopts a connectionless end-to-end data ...

Problems solved by technology

[0005] 1. The functions of the management and control planes are intertwined, making it difficult to achieve consistent management and control

Under this three-layer model, various management and control mechanisms need to collect network views by themselves to achieve control, and the control mechanism in the control plane generally adopts distributed control algorithms, and the management plane generally only uses centralized control. The control plane is affected by parameter configuration, which will inevitably lead to flood notifications on the control plane to obtain a consistent view. It can be seen that the cooperation between the management and control plane control mechanisms is extremely complex and error-prone, and these Errors will be amplified by the distributed control mechanism, making it difficult to converge network jitter and provide stable transmission, making it difficult to achieve consistent network management and control

[0006] 2. The network control function cannot be expanded

[0007] In response to these problems, the 4D network system proposed the idea of ​​centralized control, but the research did not give a clear flow of intra-domain resource control; Professor Lin Chuang of Tsinghua University proposed the concept of trusted and controllable network, aiming to solve the problem of existing network Defects in resource control to achieve predictable network resource control; our research team proposed a trusted and controllable network architecture and redesigned the hierarchical relationship of network resource control. This patent is based on trusted and controllable network The four-layer resource control model of the architecture designs a centralized resource control process in the domain
