IETF EFFORT PROMISES FEWER NET FAILURES

Shortcomings in current ways of configuring network devices has
the IETF working to standardize a network configuration protocol
known as NetConf. The thrust behind NetConf, which could be
adopted by year-end, is to reduce the programming effort
involved in automating device configuration. But is adoption by
major vendors likely? Click here for more:

Today's focus: 10 Gigabit switches at heart of Internet
exchange

By Jeff Caruso

The world's largest public Internet exchange is installing three
10 Gigabit Ethernet switches from Foundry Networks.

The Amsterdam Internet Exchange anticipates peak traffic to
exceed 100G bit/sec by the end of this month; overall volume is
growing 9% per month.

It's the world's largest public peering Internet exchange in
terms of bandwidth, clients and switch ports. The exchange is
independent, interconnecting IP networks from more than 220 ISPs
and carriers through four co-locations in Amsterdam.

The four locations all currently have Foundry BigIron switches
in a double-star topology, Foundry says.

To handle the high volume, the exchange is putting in three
BigIron RX-16 Layer 2/3 switches to form the backbone of the
exchange network. These switches will go in two of the four
locations.

This is the biggest and most powerful of Foundry's switches. It
has a switching capacity of 1.536 terabits per second. Foundry
says the switches will eventually be configured with 64 ports of
10 Gigabit Ethernet to interconnect the edge switches. Some of
the 10 Gigabit ports are even expected to serve as direct
connections to the exchange's members.

The RX-16 was introduced in the spring
<http://www.networkworld.com/nllan9259> along with two smaller
versions, the RX-4 and RX-8. In addition to Internet exchanges,
the switches are aimed at high-performance computing
environments, which have recently been a key Foundry focus.

Their strength is in large network connections packed densely
into a small space. While the Amsterdam network is putting in 64
ports of 10 Gigabit per switch, the switches are capable of
handling up to 192 wire-speed 10 Gigabit Ethernet ports and
2,304 wire-speed Gigabit Ethernet ports in a standard seven-foot
telco rack.
