While optical-transmission techniques have been researched for quite some time, optical"
networking" studies have been conducted only over the past dozen years or so. The field …

In high-speed SONET rings with point-to-point WDM links, the cost of SONET add-drop
multiplexers (S-ADMs) can be dominantly high. However, by grooming traffic (ie …

SONET add-drop multiplexers (ADMs) are the dominant cost factor in the SONET/WDM
rings. They can potentially be reduced by optical bypass via optical add-drop multiplexers …

In this paper, we consider traffic grooming in WDM/SONET ring networks when the offered
traffic is characterized by a set of traffic matrices. Our objective is to minimize the cost of …

We study wavelength assignment for lightpaths over WDM rings to minimize the SONET
ADMs (add/drop multiplexers) used. This problem has attracted much attention recently …

The SONET ring is the most widely used optical network infrastructure today. While
deploying the WDM/SONET ring, traffic grooming is an important network-design problem …

A WDM optical layer can provide differentiated services to various upper layer protocols by
forming many virtual optical networks (VONs). Polymorphic control of an optical layer in the …

In this paper, we analyze the performance of WDM networks with traffic grooming
capabilities supporting low-rate circuit-switched traffic streams. Traffic grooming in WDM …

This paper addresses the issue of capacity fairness in WDM networks with traffic grooming
capabilities, supporting lower-rate circuit-switched traffic streams. Traffic grooming in WDM …

Transparency of the optical layer offers the possibility to design a network that operates at
varying transmission bit rates. While variable bit rate interfaces are being tested and will …
