Reducing excess processes of router control requests in OSS for managing large-scale IP network

Network elements for constructing an IP network have been increasing in number with the expansion of the telecommunications infrastructure. Network subscriber services are enabled or disabled by issuing command lines (e.g., in a configuration file) for execution in network elements. Moreover, the diversification of network services and the increase in the number of subscribers are two factors that increase the number and types of management commands that need to be issued by a network management system. Therefore, to manage a network more efficiently, the importance of issuing command lines in network elements more efficiently is growing. We report on our development of a high-speed task processing method considering parallel-session status for systems remotely controlling several routers. We also show the results of simulations and propose two merging and optimizing methods for command scenarios of setting network service orders into the same network element and the same VLAN interface of a network element. These three methods are used to shorten session occupancy time per network element to achieve the maximum effect with limited session resources.
