Today's focus: Vonage uses 10 Gigabit Ethernet gear for VoIP

By Jeff Caruso

Vonage Networks this week announced that it is upgrading its
VoIP network with Force10 Networks' TeraScale E-Series of
switch/routers. While this is a nationwide network, what's
interesting is that these switches use Gigabit and 10 Gigabit
Ethernet.

Vonage is one of the poster companies for VoIP, and it provides
broadband telephone services to U.S. residential customers. The
company says it grew more quickly than it expected, and now it
needs to upgrade a network that's just four years old. The new
equipment gives Vonage high density and resiliency, the company
says.

Force10 points to the win as proof that Ethernet's magic is
working in the wide area. While Ethernet, as everyone knows, got
its start in the LAN, it is now being taken quite seriously as a
WAN transport.

The Force10 equipment will go into points of presence in major
metropolitan areas across the country. The TeraScale E-Series
switch/routers will go in the core of Vonage's network, allowing
Vonage to collapse its distribution and aggregation layers into
a single layer.

These devices have 5T bit/sec of capacity on their backplanes
and can support up to 672 lines of Gigabit Ethernet or 56 lines
of 10 Gigabit. Force10 claims the system in the future can
support even higher densities or move to 40G bit/sec or 100G
bit/sec Ethernet if such a thing were ever to come to pass.

They handle IP-based phone calls for Vonage, which allows
customers to make and receive those calls from a high-speed
Internet connection.
