Metro optical networking

Bell Labs Technical Journal, 2002
Today's telecommunication networks support an ever-increasing mixture of statistical and deterministic data traffic. Current networks rely on time division multiplexing (TDM) hierarchy, originally invented to be the most efficient multiplexing technique possible for 64-kb/s voice, but this architecture is not particularly suited to statistical data ...

Cognitive Optical Networks

2018 IEEE International Conference on Communications (ICC), 2018
Future optical networks will have 103-4 increase in rates and highly granular traffic due to large transactions. Cognitive techniques will provide agile automated fast scheduling of resources, topology changes and agile adaptations for congestion control, load balancing and reconfiguration involving all layers.

OCON: an optically controlled optical network

Computer Communications, 1999
The centralized filtering of the transmitted packets has been the base of a family of high-performance protocols for Wavelength Division Multiplexing (WDM) Star Networks (G.I. Papadimitriou, D.G. Maritsas, WDM star networks: hybrid random access and reservation protocols with high throughput and low delay, Computer Networks and ISDN Systems, 28(6 ...

Multicasting in Optical Networks

2001
Optics is a key technology in communication networks to enable bandwidth intensive applications, such as video conferencing, real-time medical imaging, broadcasting services to home [5]. Readers interested in the relevant aspects of fiber optic technology are referred to [11,15,17].

Progress in optical networking

IEEE Communications Magazine, 2001
This article summarizes the present state of optical networking, how we got to this point, and what needs to be done to complete the job. The point of departure is an assumed future two-level structure in which the transport is by means of steadily growing interconnected all-optical islands of transparency, while the remainder of the communication ...

Optical cross connects for optical networking

Bell Labs Technical Journal, 2002
As the transmission line rate supported by optical fibers increased from 45 Mb/s to 2.5 Gb/s during the 1980s, interexchange carrier networks introduced various digital cross connects to provision, groom, and restore DS0 (64-kb/s), DS1 (1.5-Mb/s), and DS3 (45-Mb/s) traffic. With the recent release of its WaveStar™ Optical Line System (OLS) 400G, Lucent

Optical Network Design with Optical Constraints in IP/WDM Networks

IEICE Transactions on Communications, 2005
In this paper we consider algorithms for the logical topology design and traffic grooming problem in WDM networks with router interface constraints as well as optical constraints. The optical constraints include restricted transmission range due to optical impairments as well as limits on the number of available wavelengths.

Network Visualization for Optical Transport Networks

2020 22nd International Conference on Transparent Optical Networks (ICTON), 2020
Human interpretation of the network condition plays a key role in managing the network and services; information visualization allows network administrators to understand the behaviour of the managed network. Optical transport networks are inherently multivendor and multidomain networks, and the associated network management functions often make use of

Optical transport networks

Proceedings of the IEEE, 1993
The key technologies required for the development of optical transport networks, namely, optical fiber transmission and digital transport, which includes transmission signal multiplexing, transport nodes, and network operation functions, are highlighted.
