Cable & Wireless Plc is upgrading its network access and peering points in the US. It is building OC-12 (622Mbps) connectors to its NAPs and installing new ATM switches at the metropolitan area exchanges (MAEs). It will also build OC-3 (155.52 Mbps) and OC-12 connections to its largest direct peers and is installing at least 25 new DS-3s for existing and new peers. The company has about 40 peering arrangements with ISPs. It told us recently that it does not charge for peering, but checks out the other ISP extensively before agreeing to the arrangement and monitors the traffic constantly to ensure it is not getting too one-sided. The OC-12 connection doubles the company’s current public peering capacity, it says. These network enhancements will happen mainly during this quarter, with some continuing in the second quarter. The company says it is investing $500,000 in the first quarter alone.
