Abstract
Disclosed herein is a system and method to implement end-to-end QoS for connections in IP-based networks, even when the communications are between different subnetworks. In accordance with an embodiment of the invention, QoS is provided between subnet routers that are attached to the network through a network backbone. An embodiment of the invention can differentiate connections between routers and can classify data streams for both inter-subnet and intra-subnet connections using only information provided in the IP headers and without requiring any special tags or other identifiers to be added to the packet.
