The provided network architecture introduces QoS into the ADN, in a manner that enables the delivery of sophisticated and demanding IP-based services (13) to subscribers (25), does not affect existing Internet tiers of service, and is cost-effective in term of initial costs, build-out, and ongoing operations. 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 the 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 (13). Systems coupled to the network and software in a user's computer enable a method for automated, end-to-end provisioning of a logical data circuit, in response to a customer's request for bundled broadband services. |
