Multi-protocol congestion management in Ethernet networks: Bringing consistency of functionality to oversubscribed Ethernet
By Mathew Steinberg, Ample Communications -- To minimize the degradation of network performance in cases of congestion and to ensure that critical traffic is transmitted, service providers should implement intelligent oversubscription.
Using VPNs to deliver prioritized business services
By Peter Lunk, Extreme Networks -- While MPLS has established itself in the marketplace, emerging native Ethernet technologies present a compelling alternative to MPLS.
Selecting the Ethernet services strategy that's right for your business, infrastructure, and customer base
By Umesh Kukreja, Atrica -- From its start as a standard platform for enterprise LAN networking, Ethernet has evolved into Carrier Ethernet--a widely adopted platform for WAN services.
Applications for two-degree and multi-degree reconfigurable add/drop multiplexers
By Sorin Tibuleac, Movaz Networks -- Today's network operators are finding distinct applications for two-degree and multi-degree ROADMs. In many cases, the two ROADM types may coexist and complement each other to redefine the DWDM layer in new optical networks.
Optical amplification requirements in metro ROADM networks
By Ahmad Atieh and Robin Andrew, BTI Photonic Systems -- Optical extension designs provide an efficient, cost-effective model for deploying ROADMs in metro networks.
Agile optical networking reduces cost and complexity in WDM networks
By Steven D. Robinson, Meriton Networks -- Agile optical networking eliminates cost and complexity from existing carrier networks by creating a fully automated optical layer.
Evolution to enhanced reconfigurable optical add/drop multiplexers
By Fady Masoud, Nortel -- The enhanced ROADM architecture leverages the simplicity, precision, and flexibility of micro-electromechanical systems (MEMS) technology to enable unrestricted add/drop and redirection of any wavelength at any port.
Reconfigurable optical networks: Paving the way for dynamic wavelength routing
By Vinay Rathore, Ciena -- By combining electrical grooming and wavelength-selective switching (WSS) into a dynamic wavelength routing (DWR) solution, operators can address both full-wavelength and sub-wavelength services at cost points that render ROADMs economical today while meeting increasing bandwidth demands in the future.
Copper SFP transceivers bring flexibility to the network
By Rafik Ward, Finisar -- From increased port density and flexibility to logistical and inventory advantages, the use of copper SFP transceivers is a promising development for the optics industry.
Video QoS in triple-play networks
By Christer Bohm, Net Insight AB -- A comparison of SONET/SDH-based NGN transport and packet-only approaches may surprise you.
