The paper continues research on the use of the Software-Defined Networking (SDN) concept in the IP Multimedia Subsystem/Next Generation Network (IMS/NGN) transport stratum to increase flexibility of transport resource control and management mechanisms and make them independent of hardware solutions. The developed simulation model is used to examine the IMS/NGN network performance expressed by standardized Call Processing Performance (CPP) parameters such as mean Call Set-up Delay and mean Call Disengagement Delay. The research is carried out in a multidomain network, taking into account a wide range of service scenarios as well as parameters of network and generated traffic. As a result, the parameters, which are most important from the point of view of the performance are indicated, along with possible further steps to increase the performance.

摘要

The paper continues research on the use of the Software-Defined Networking (SDN) concept in the IP Multimedia Subsystem/Next Generation Network (IMS/NGN) transport stratum to increase flexibility of transport resource control and management mechanisms and make them independent of hardware solutions. The developed simulation model is used to examine the IMS/NGN network performance expressed by standardized Call Processing Performance (CPP) parameters such as mean Call Set-up Delay and mean Call Disengagement Delay. The research is carried out in a multidomain network, taking into account a wide range of service scenarios as well as parameters of network and generated traffic. As a result, the parameters, which are most important from the point of view of the performance are indicated, along with possible further steps to increase the performance.
