Design And Implementation Of Management System For Smart Identifier Network

Shortcomings of the original Internet design have affected the further development of the Internet.Therefore,countries around the world have carried out a lot of researches on the future network architecture,such as Smart Identifier Network(SINET)with the"three-layer"and "two-domain" structural models.In practical deployment,SINET is divided into two parts:the access network and the core network.In the access network,the virtualization of components is implemented by introducing the concept of "Function-group".In the core network,secure transmission of data packets is achieved through mapping of Node Identifier(NID).The existing network management system does not have targeted management of the access network and the core network of SINET,and cannot be effectively used for the management of SINET.In order to solve the above problems,this paper designs and implements a domainized management system for SINET,which respectively designs and implements the network management system for the access network and the core network,so that managers can manage and control the entire network to achieve better control and coordinate the services,resources and nodes in SINET.The main work of this paper includes the following three parts:(1)This paper designs and implements a domainized management system structure for SINET.In this paper,the management system is divided into two subsystems:the access network management system and the core network management system.The access network management system focuses on the management of node resources.The core network management system focuses on the management of node identifier mapping and routing.Through a unified management system platform,administrator can view and configure all sub-management systems in the management system.The domainized structure of the management system for the targeted design of the access network and the core network enables the administrator to comprehensively manage the entire network,and ensure the stable operation of SINET in the access network and the core network more effectively.(2)This paper designs and implements an access network management system for resource management.This paper uses the OpenStack platform to realize the underlying resource virtualization,focuses on the design and implementation of the monitoring module,the alarm module and the underlying resource interaction module.The monitoring module uses the time series database to store performance data and improve the system access speed.At the same time,the visualization module is added to facilitate the management of the nodes,performance and network in SINET through the Web interface,and finally achieves real-time and effective management of the resources of the network component layer in the access network.(3)This paper designs and implements a core network management system for mapping and routing management.In this paper,SINET is integrated with the OpenFlow network,and NID is divided into Access Identifier(AID)and Routing Identifier(RID).The design and implementation of the separation mapping module,the dynamic routing module and the forwarding policy delivery module are emphasized.A mechanism named User-driven and Network-aware Path Selection Mechanism(UNPSM)and a mechanism named full-path bidirectional flow table delivery mechanism are proposed,in order to meet user needs and make full use of network resources at the same time,and meanwhile speeds up the mapping and forwarding process.At the same time,the visualization module is added to facilitate the management of the mapping entries and routing strategies in the network through the web interface.The management of mapping and routing in the core network is finally achieved.Finally,this paper conducts several functional tests and performance tests on the management system.Through the analysis of the results,it is proved that the management system for SINET can manage the resources of the access network,and manage the mapping and routing of the core network,and realize the comprehensive and effective management of the whole network,thus guarantees the stable operation of SINET.
