We review recent progress on all‐optical virtual‐private‐network (VPN) schemes in passive
optical networks (PONs). PON is a promising candidate in future access areas to provide …

Optical burst switching (OBS) is a very efficient all optical transmission network. But the
performance of the network may reduce because of the burst losses. Hence, to eliminate the …

Abstract While the “Virtual Private Network (VPN) over Internet” is cost-effective and flexible,
it suffers from the difficulty of providing adequate transmission capacity for high bandwidth …

Over the past decade, the improvement of communications technologies and the rapid
spread of www (World Wide Web) have brought on the exponential growth of users using …

Routing technologies considering QoS-based hypermedia services have been seen as a
crucial network property in next generation optical Internet (NGOI) networks based on …

A major challenge in next generation optical Internet (NGOI) networks based on dense-
wavelength division multiplexing (DWDM) is the provision of guaranteed quality-of-service …
