The Amsterdam Internet Exchange (AMS-IX) is claiming to be the world's largest public Internet exchange, after setting a new traffic record earlier this month of 233Gbit/s. It says it now shifts more than 1.5 Petabytes a day, on behalf of over 250 ISPs and carriers.

To support that load, AMS-IX has had to invest in yet more switching capacity. It has built up its duplicated core network, which now comprises six BigIron RX-16 switches from Foundry Networks. These are installed in two of its four co-location sites, and once fully configured, the core switches will have 64 10Gig ports each for connection to edge switches and 10Gig customers.

"AMS-IX hit a historical milestone in November when traffic flowing across our infrastructure exceeded 200Gbit/s," said Henk Steenman, the exchange's CTO. Traffic volumes continue to increase at around 3 percent a month, he added. ®
