Abstract

The provided network architecture introduces QoS into the AND (10), in a manner that enables the delivery of sophisticated and demanding IP-based services (13) to subscribers. The architecture utilizes a switch (19) capable of examining and selectively forwarding packets or frames based on higher layer information in the protocol stack, that is to say on information that is encapsulated in layer-2 information utilized to define normal connectivity through the network. The switch (19) enables segregation of upstream traffic by type and downstream aggregation of Internet traffic together with traffic from a local vertical services domain. Customer Premises Equipment (CPE) (1000) located between the AND (10) and customer premises data equipment examines frames received from the data equipment and modifies the frames according to the destination of the frames' payloads. This CPE (1000) also enforces Qos guarantees in the upstream direction and security-related access control lists.
