Resource: Ethernet QoS Overview

 

A new eBook from Fierce Telecom covers Ethernet QoS:

"While Ethernet has grown in popularity in recent years, the service still lacked the predictability and QoS and CoS elements found in traditional SONET, and later Frame Relay and ATM services. Maintaining Ethernet QoS becomes an even more acute problem when service providers have to go off-net to serve a particular customer location and work with a carrier partner. Such a scenario is a growing reality for both incumbent and even growing competitive service providers that are expanding their focus on medium and large businesses that have multiple locations".
