An efficient provisioning mechanism for in-service migration in access network

The tremendous bandwidth demand for content-rich services on service providers initiates new access networks deployment and leads the networks increasingly complex and functional. In general, the commercial access networks are composed of a large number heterogeneous, multi-domain, multi-technology and multi-vendor network devices. In such a network environment, the network migration is a challenging task for any service providers. The process of network migration traditionally involved a series of manual and repetitive steps. The manual process of network migration requires highly skilled staffs and is prone to human error. In this paper, we present the integrated and automated provisioning operational supporting systems (OSSs) for in-service network migration. The developed OSSs provide two kinds of in-service network migration mechanisms and support a diversity of network migration scenarios in heterogeneous networks. Finally, the results show that the proposed efficient provisioning mechanism significantly speeds up the network migration and reduces service providers´ operational expenditures (OPEX).
