Design And Implementation Of Configuration Negotiation Protocol In P-Based Autonomic Network

The traditional Internet architecture can’t adapt to the development of Internet in many ways while there are increasing various network elements and user demands, complex network management configuration and so on. Autonomic network architecture is one of the hot topics in research of the future network architecture. Autonomic network based on negotiation is a novel autonomic network design, network elements embedded intelligence negotiate and cooperate with each other independently to realize the organization and management of the network business and service, this model can overcome the shortcomings of centralized network management, and provide a technical solution which is flexible and easy to extend.In this thesis, the key technology of autonomic negotiation network is studied. This thesis briefly describes the architecture of autonomic negotiation network, and the architecture consists of a thin decision plane and a network consisting of intelligent devices. Thin decision plane is responsible for the network equipment role and task allocation, according to the role or tasks, intelligent equipment negotiate and cooperate with each other to complete the corresponding configuration. Network equipment embedded intelligence are the key elements of autonomic negotiation network, they have basic attributes of self-description, self-discovery, analysis and decision, negotiating communication. Follow modularity, scalability and interoperability of software engineering, system structure of autonomic negotiation equipment are divided into communication layer and implement layer. Communication layer provides communication ability for the negotiation between entities, and independent function units which are service-oriented combined together realize network configuration of the business. This thesis analyzes negotiation information interaction, such as the blackboard system, end-to-end model and group communication, then put forward the "point-to-point interaction adding neighbors diverting function". The negotiation protocol is foundation of autonomic negotiation communications, the available negotiation protocols are discussed in this thesis.This thesis depending on the project "IP-Based autonomic archetypal system" which is a cooperative project between laboratory and huawei, applies negotiation key technology to IP RAN network scenario, and implements self-organization of the network connectivity and self-organization L3VPN resources. The communications infrastructure of autonomic archetypal system is based on the general configuration negotiation protocol, and this thesis describes the detailed design and implementation of configuration negotiation protocol, finally the configuration negotiation protocol is applied to autonomic prototype system for validation.
