Adaptive Clock Recovery Mechanism Having Dynamic Frequency Drift and Buffer Level Control in Packet Switched Networks

Adaptive clock recovery is required in order to transmit the synchronous data of conventional time-division multiplexing (TDM) services to another TDM network across an asynchronous packet switched network (PSN). In this paper, we propose an adaptive clock recovery mechanism having dynamic frequency...

Description
Summary:Adaptive clock recovery is required in order to transmit the synchronous data of conventional time-division multiplexing (TDM) services to another TDM network across an asynchronous packet switched network (PSN). In this paper, we propose an adaptive clock recovery mechanism having dynamic frequency drift, which enables faster response with smaller residual variance, and buffer level control to reduce the required jitter buffer size with no buffer underflow or overflow.
