Nortel Merges Dynamic Routing, IPSec in Gateways

Nortel announced five new Contivity Secure IP Services Gateways at NetWorld+Interop this week that allow enterprises to deliver secure IP services, such as quality of service, firewalls and bandwidth management, while lowering total cost of ownership. While the Contivity line already allowed for the combining of IP services, the latest additions allow for dynamic routing support within the gateway, said John Doyle, director of product marketing for the Intelligent Internet group at Nortel. Previously, routing capabilities were limited because IPSec, a core part of security in VPNs, does not support dynamic routing, forcing manual configuration by network administrators, he said.
With dynamic routing merged with IPSec, customers can deploy the new devices initially as secure routers. They then can add additional VPN capabilities beyond the five tunnels that come standard or other IP services by turning on, through software, what Nortel calls "license keys," Doyle said.
