<div><div>, traffic classification could be based on source address prefix mapping to corresponding exit link. IETF Homenet workgroup is looking for such. Having it, SmartGateway would get deprecated, as all routers forward to right border and no NAT is in use. And no connection state at all in routers. No encap, no MTU problems. And my favorite: multi-path.</div>
