Admission control system supporting strategy space dynamic expansion and control method thereof

Abstract

The invention discloses an admission control system supporting strategy space dynamic expansion and a control method thereof. The invention mainly solves the problems that the existing admission control method can not emerge along new user service, and the security reliability of dynamic expansion strategy space is poor when network state changes. The system comprises a user service information extraction module, a network information extraction module, a strategy repertoire and an admission control module. The control method comprises the following steps: extracting flow information and network operational state information from the information flow and the network; extracting the attribute value of strategy space from the information; generating attribute vector of the strategy space and the structure of the strategy space; comparing the attribute vector of the strategy space and the structure of the strategy space, checking whether the attribute vector and the structure of the strategy space are consistent or not; if so, matching strategy output results, if the strategy is simultaneously updated, the new strategy is stored in the strategy repertoire; if not, changing the attribute value or changing strategy attribute and dynamical expansion strategy space, and repeating the step. The invention can be used in military telecommunication nets and IP exchange nets.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to a packet switching network management control method, in particular to an admission control method, which supports dynamic expansion of policy space, and can be used in packet switching networks such as military communication networks and IP switching networks. Background technique [0002] Any computing environment, including the Internet, always has limited resources, and each task has resource requirements closely related to its quality of service (QoS) requirements. The basic purpose of admission control is to achieve the highest possible utilization of network resources through dynamic resource sharing on the premise of ensuring the QoS of the admission service. [0003] At present, the policy-based admission control method is mainly used. It not only needs to consider the traditional QoS information, such as the request of the sender and the available resources of the n...

AI Technical Summary

Problems solved by technology

The current policy admission control method does not take into account the extraction of user confidentiality level, business service quality, access time, access point and other information to configure policies in a large policy space, so as to meet access security and reliability requirements ; while the current admission control method uses static policies for admission control, which does not fully consider the dynamic characteristics of the network environment, such as network status changes, new users and new services, etc., not only cannot meet the wide and diverse user needs, but also lead to business security. Sexual reliability cannot dynamically adapt to network changes
