Scalability at
the Edge: When is enough enough?
The challenges facing edge devices today
are well documented. Functioning as the
link between broadband access networks and
the Internet core, edge routers have the
Herculean task of aggregating, forwarding,
and routing traffic at wire speed while
simultaneously providing a wide array of
value-added services, including QoS management.
This white paper examines the inherent scalability
problems of legacy metro/edge networks and
describes key scalability tests and goals
for some of the innovative routing architectures
and technologies now emerging at the edge.
