In one embodiment, a router is deployed on a local area network (LAN) in addition to any routers deployed on a wide area network (WAN) coupled with the LAN having the router. A service management device is coupled between the two routers. The service management device provides management processing, for example, quality of service (QoS) processing, traffic shaping, type of service (ToS) processing, or class of service (CoS) processing. For messages between devices both coupled to the WAN router, the WAN router diverts the messages to the LAN router. The LAN router then returns the messages back to the WAN router through the service management device, which provides management processing. The WAN router then forwards the processed message to the destination device.
