Switching and Traffic Grooming in WDM Networks

This paper considers the role of switching in minimizing the number of electronic ports (e.g., SONET ADMs) in an optical network that carries sub-wavelength traffic. Providing nodes with the ability to switch traffic between wavelengths, such as through the use of SONET cross-connects, can reduce the required number of electronic...

How Cisco IT Migrated TDM Local Access From SONET to OC-192 Infrastructure

By 2003, 18 more Cisco buildings on the San Jose campus were using so much capacity that customer-provided access would be more economical, but Cisco could not add these buildings to the legacy infrastructure of unconnected SONET rings. The legacy infrastructure had other drawbacks as well, including high management burden,...

Five Reasons to Adopt Layer 2 Ethernet Switching Over DWDM Networks Now

A new network is emerging for delivering media-rich and bandwidth-hungry content, applications and services. Traditional SONET Synchronous Optical NETwork/SDH Synchronous Digital Hierarchy architectures, developed for the narrowband world of a generation ago, are overloaded. Such practices as stacking SONET/SDH rings to increase capacity are complex and costly, while Ethernet-over-SONET/SDH protocol...

Introduction to SONET

SONET stands for Synchronous Optical NETwork. The SONET format allows different types of formats to be transmitted on one line. SONET is a long term solution for a mid-span-meet between vendors. The other major advantage is that SONET allows ADDING and DROPING signals with a single multiplexer. Communication between various...

Wavelength Assignment to Minimize the Number of SONET ADMs in WDM Rings

Optical Wavelength Division Multiplexing WDM rings are being deployed to support SONET/SDH self-healing rings. The cost of such a system is dominated by the SONET Add/Drop Multiplexers ADMs. To minimize the system cost, algorithms must be developed to assign wavelengths to lightpaths in the system so that the number of...
