QoS evaluation of KT-NGN

KT is considering the installation of a new IP router with a backbone network for implementation of NGN. QoS discussions on whether the IP router satisfies the forthcoming NGN customers who use basic and application NGN services still remain. QoS values as packet delay, packet loss and jitter are measured and analyzed at the KT-NGN test bed, and are compared with the ITU-T QoS recommendation values. Most of the measured QoS values are within ITU-T recommendations so we can assert that KT decision of IP router for NGN backbone installation is correct.
