Abstract

A network architecture includes a switch that can examine and selectively forward packets or frames based on information encapsulated in layer-2 information in the protocol stack. The switch segregates upstream traffic by data type and aggregates downstream Internet traffic with traffic from a local vertical services domain. The network architecture provides an efficiency way to insert vertical services.
