As a model whose primary purpose is to provide a framework for home networking services, TR-059 relies extensively on the BRAS device to deliver IP flow and session-level awareness where multiple services and applications share a common DSL line. net.com's SCREAM® meets the stringent demands of a TR-059 BRAS, enabling service providers to deliver tiered IP QoS guarantees and bandwidth on demand across today's DSL infrastructure.
Residing in a wholesale network service provider's tier 1 or tier 2 central office, the SCREAM both replaces the classic Subscriber Management System (SMS) and a retail ISP's existing BRAS platform. The BRAS functionality essentially evolves from that of an ISP element to a carrier network resource.
Delivering dynamic, on demand, IP QoS guarantees over the existing ATM transmission infrastructure - modeling IP traffic across multiple downstream ATM hops using only a single provisioning VC - requires a tight coupling of the ATM switching and IP Edge Routing functions of this next-generation BRAS platform.
net.com's integrated QServ technology not only provides comprehensive native IP and ATM traffic management features, but also ensures that high-priority shaped IP flows and sessions are not delayed or discarded during the critical hierarchical ATM layer shaping process. Only in this way, can TR-059 compliance be achieved. |
