Abstract:
1. A data network comprising: an ingress aggregation router for aggregating data flow; an egress aggregation router; and a core network backbone interfacing with both the ingress and egress aggregation routers, the backbone including a plurality of backbone routers configurable into pipes of varying capacity connecting the ingress and egress aggregation routers; the ingress aggregation router being configured to separately aggregate voice call flows into a single queue, to request aggregate bandwidth for voice call flows as a separate class from other classes of traffic, and to resize a pipe carrying the aggregate bandwidth and connecting the ingress and egress routers on a periodic basis; the ingress aggregation router further being configured to transmit capacity reservation requests through a pipe in the backbone, the capacity reservation requests being hidden from the backbone routers configured into the pipe.
