基于WiFi的WMN多規(guī)模網(wǎng)管平臺研究
[Abstract]:In recent years, wireless Mesh network based on WiFi, I. E. WWMN network, has developed rapidly. From home suite and campus deployment to enterprise deployment and even operation-level deployment, WWMN network has gradually evolved into an important support for smart city. With the explosive growth of network scale, a single network management scheme can not meet the demand more and more, which is mainly reflected in the huge difference of network management requirements between different scenarios and different size of WWMN networks. Therefore, a set of solutions that can adapt to a variety of different scale network management has become an urgent need. Aiming at the problem of wireless network deployment in the construction of smart city, this paper presents the design method of network management platform of wireless Mesh network based on WiFi, and solves the complex network management problem which adapts to different scale WWMN deployment respectively. The main research results are as follows: (1) for small-scale WWMN (typical application scenario: home, office), a network management platform based on SNMP protocol is designed and implemented in this paper. This paper first analyzes the characteristics and management requirements of small-scale WWMN network, and then completes the development of server, device-side manager and agent on the basis of this. In the process of agent development, a comprehensive and detailed MIB library is designed. Finally, the OpenWrt system including the network management system is transplanted to the router, and the application of the network management system based on SNMP protocol is realized. Through a series of tests on routers, the advantages of the network management platform based on SNMP protocol in small-scale WWMN network management are further verified. The practice shows that the WWMN network management platform based on SNMP protocol meets the application requirements of small-scale network deployment management. (2) for the medium-scale WWMN (typical application scenario: campus-level deployment, community-level deployment, lightweight operational deployment network), This paper presents a network management platform based on CAPWAP protocol. Through the analysis of CAPWAP protocol, the design scheme based on CAPWAP network platform is established. The scheme adopts AC FITAP structure management to make large-scale network management possible. The design scheme includes local forwarding technology, design of management information base, network management of application configuration, device configuration management and system management, etc. The design scheme includes local forwarding technology, management information base design, network management of application program configuration, device configuration management and system management. On this basis, this paper further discusses the implementation of network management platform based on CAPWAP protocol, and realizes the CAPWAP communication between AC and FIT AP by means of OpenCapwap. Finally, WWMN is deployed on campus network and its management model is planned. (3) for large-scale WWMN (typical application scenario: operational-level deployment, cross-campus, cross-regional, cross-city and even cross-border networks), This paper presents a network management platform based on CSP. The scheme adopts cloud service platform and virtual share manager technology to make this kind of large-scale network management possible. The scheme divides large-scale network into security domain and VLAN for block, hierarchical management, and realizes Web management, bandwidth management and roaming management under the four-layer architecture of cloud service platform data center, virtual sharing manager, AP wireless access and user. Virtual sharing mode management and data forwarding control management. Finally, this paper discusses the implementation of CSP-based network management platform, including OpenStack virtual network management and CSP-based network management campus network implementation.
