Research institutions, individuals and some standardization organizations are provided with several solutions for integrating the IP network and the transport network management. These solutions, however, focus only on the technical aspects of interoperability between the IP network and the Transport Network Management Systems (T-NMS). The paper addresses the interoperability problem from a business process perspective. Web Service Business Process Execution Language (WS-BPEL) is used to describe and align the processes of the IP Network Management System (IP-NMS), T-NMS and a mediator that works between those management systems. In addition to this, the performance of the mediator is compared for processing single and multiple requests in terms of time, reliability and cost of process. The results showed that it is economical and timesaving to process multiple requests at a time, while single request gives higher reliability. It is believed that the solution would provide high flexibility and lead to an effective network management interaction between IP-NMS and the T-NMS.
The Internet had experienced an exponential growth in the number of networks, computers and users in the last decade (Marinescu, 2002). The Internet end users use the Internet to perform more complex activities and stay a long time on the network, which leads to traffic congestion or traffic delays in the network. The global consumer IP traffic, 2011-2016 is expected to reach 96.4 exabytes per month in 2016 (CISCO, 2012). Through this higher demand for Internet access, the IP network has been facing challenges in finding solutions that could manage available network capacity in a flexible manner. Currently, transport networks are the foundation for packet networks, such as IP and Time Division Multiplexing (TDM) infrastructure like telephony network. Therefore, transport networks need to offer high level of reliability. The transport network is managed by a Transport Network Management System (T-NMS), while the IP network device is managed by IP Network Management System (IP-NMS) (Yannuzzi et al., 2011).
