Abstract

The popularization of Internet applications has aroused drastic increase in demand of Internet Protocol (IP) network bandwidth and quality of services (QoS). In view of this trend, optical label-switching (OLS)¹ has emerged as a promising solution for the future Internet. OLS achieves low-latency high-speed packet forwarding in the optical layer using all-optical label swapping techniques,^2,3 while the multi-protocol label switching (MPLS) control component offers traffic engineering capability enabling end-to-end QoS.
