Abstract
When a disaster occurs, the demand for information and communication technology (ICT) services drastically increases. To meet such demands, a national project was undertaken in Japan to develop the Movable and Deployable ICT Resource Unit (MDRU). One challenge regarding the MDRU is securing operators to work the units in emergency situations. As ICT service users have diverse and frequently changing demands, strong technical skills and practical knowledge are required for the administration of MDRUs. In this paper, we propose a knowledge-based network management system to alleviate the burden on administrators. To deal with the structural changes to network systems that frequently occur with changes in ICT service demand, we introduce modularization techniques into our previous research. The proposed system can be easily reconfigured by join/disjoin modules corresponding to changes in the system configuration of the MDRU. The results of our experiments using the implemented experimental system confirm that the proposed system can be applied to MDRU operation and effectively supports administrators.
Highlights
In recent years, with the advancement of virtualization technology and a reduction in the price of computing resources, it has become easier to build platforms to provide information and communication technology (ICT) services
We propose a Knowledge-based Network Management Systems (KNMSs) that can flexibly add or revise knowledge according to changes in the configuration of the Movable and Deployable ICT Resource Unit (MDRU) system
We extend our previous research [16] and develop the KNMS, which can be applied to MDRU operation
Summary
With the advancement of virtualization technology and a reduction in the price of computing resources, it has become easier to build platforms to provide information and communication technology (ICT) services. With the advent of the concept of network functions virtualization, it is possible to flexibly construct and reconfigure network infrastructure. With such a growing trend in virtualization technology, a novel method of constructing and operating ICT services has been proposed by a project led by the Ministry of Internal Affairs and Communications in Japan [4] [5]. In this way, ICT services can be quickly restored in disaster situations
