well , ant router must have at least one thernet interface , because it is the default gateway of the LAN , and at least one Serial/WAN interface , there are routers that contain many eth. , Ser. interfaces to connect many LAN's and many WAN's toogeather.

Concerning Queuing , there are many algorithms for queing like : LLQ , WFQ , .....
they are invoked through commands on each interface but they are most implemented on Serial/WAN interfaces because they have low bitrate comparing to the Ethernt interfaces (10/100/1000 Mbps) , and this issue is a very important part of what is called Quality of Service (QoS) policy .
