Design And Implementation Of Switch Management System Based On ONOS

With the development of cloud computing,data volume grows explosive,higher requirements are put forward for the network operation and maintenance of enterprise data centers.Different brands of switches have different configuration commands,which makes the operation and maintenance of hybrid networks more difficult.Although using network equipment provided by a supplier can theoretically provide high-quality network services,in order to reduce the excessive dependence on a device manufacturer,enterprises often adopt hybrid network strategy,which is accompanied by the improvement of operation and maintenance difficulty.Centralized management and unified control of network equipment is an urgent need for network operation and maintenance.For network operation and maintenance,this paper designs and implements a switch management system based on ONOS.ONOS has different driver schemes for switch management.This system realizes an adaptation template.When adding new devices,there is no need to change the ONOS source code,only need to add the corresponding command line and product model to the interface,and automatically generate a driver for different switches.This system provides the functions of switch status information acquisition,physical network visualization,traffic prediction,fault analysis and so on,which reduces the difficulty of user network operation and maintenance.Switch status information includes version type,port status,traffic statistics,packet statistics and so on.Physical network visualization is responsible for displaying physical network topology on the ONOS interface,that is,the connection between physical devices.Traffic prediction function is based on traffic and other information of network equipment to locate the bottleneck of network traffic.Fault analysis is responsible for providing corresponding repair suggestions for different types of network faults.This system is based on ONOS platform.It monitors the switch through SNMP protocol and configures the switch through NETCONF protocol.Switch equipment involves Huawei,H3 C,Cisco,Centec and Ruijie manufacturer products.This system is of great significance for enterprises to save network management costs and improve work efficiency.
