The need for network bandwidthand more specifically, for efficient use of that bandwidth, is transforming thetypical carrier core network from a T3 infrastructure with a single class of serviceto a multigigabit optical network with multiple classes of service. As a result, theequipment used to build these networks has become more specialized to addressthe multiple needs of edge concentration.Routers designed for enterprise networks are often used on the edge of serviceprovider networks to concentrate leased-line traffic destined for the core. Theoverutilization of these routers is driving demand for a new device that canaggregate traffic from multiple leased lines onto an optical network, whilemaintaining support for multiple levels of service.The Versalar 15000 is the first Internet aggregation router designed to address theneeds of next-generation service provider networks. Its extremely high portdensity provides access, traffic management, and accounting information for over1000 simultaneous IP sessions.
