Arup Acharya, Rajiv Dighe: System and method of transferring internet protocol packets using fast ATM cell transport. NEC USA, Sughrue Mion PLLC, January 29, 2002: US06343326 (51 worldwide citation)

In a method of transmitting an IP packet between a source and a destination through an ATM network which has a node formed by an ATM switch and a packet router, a reception packet or cell is transmitted to the node on an unused or undefined VC and is sent to the packet router in the node. In the pac ...
