?– Applications Current and emerging applications supporting a host of business,
information, and entertainment applications and benefiting from the convergence
of voice, data, and video. The landscape or breadth of application support is a vital
driver for Carrier Ethernet.
?– Bandwidth Bandwidth scales from 1M to 10G in granular increments of 1M,
enabling a much more palatable solution to both the end user and Service Provider
because end users only have to ???pay for what is required??? and Service Providers
would possibly receive higher revenues.
As these dimensions scale collectively, they make for a formidable problem to deliver,
isolate, troubleshoot, and in general, manage thousands of users and hundreds of thousands
of services in a robust manner.
Reliability As Carrier Ethernet services are expected to support mission-critical applications
on a wide scale, the ability to detect quickly and remotely any failures that may arise
in the physical infrastructure or in the Ethernet services layer underlying these applications
is essential. Specifically, the following aspects are addressed by Carrier Ethernet.
?– Service Resiliency The impact of failures is localized and will not affect other
customers and/or applications; Correlation among multiple errors will be quickly
identified.
