- Abstract
- Recently NGN standard organizations provide significant effort to implement the QoS guaranteed service in the IP based packet switching network. The NGN architecture assumes the admission control for all the premium service and monitoring the service performance to meet the QoS requirement. In Korea, Broadband Convergence Network (BcN) architecture has been developed. BcN strategy is delivering NGN solution by converging different types of services. The service reliability and performance of BcN is maintained by OAM over Virtual Switched Path (VSP). However, no clear solution for monitoring the delay performance network is available for asynchronous packet switching network. This paper presents the BcN architecture and introduces the performance monitoring and control algorithm for packet switching network. First part of the paper presents BcN architecture in both transport and control plane. The second part introduces a delay measurement algorithm designed for BcN network called DiffProbe (Differentiated Probe). DiffProbe is OAM based delay measurement algorithm that can be used for delay measurement in asynchronous transport network where the clock synchronization is not available. Network control strategy using DiffProbe is also presented. Based on the simulation result, DiffProbe captures the delay dynamics in high load condition.
