Network interworking device for IP network / ATM network
First Claim
1. A network interworking device for executing conversion between IP packets and ATM cells, said network interworking device being connected between a first communication network in which information is transmitted in a form of the IP packets and a second communication network in which information is transmitted in a form of the ATM cells, said first communication network having a hierarchy structure with an IP layer, said second communication network having a hierarchy structure with an ML layer, said network interworking device comprising:
- means for assembling a plurality of ATM cells in the AAL layer of said second communication network into an IP packet when the plurality of ATM cells are to be transmitted to the same address in said first communication network, said assembled IP packet being transmitted to said IP layer; and
means for disassembling an IP packet in the IP layer of said first communication network into a plurality of ATM cells, said disassembled ATM cells being transmitted to said AAL layer.

Abstract
A network interworking device for executing conversion between IP packets and ATM cells, the network interworking device being to be connected between an IP network in which information are transmitted in a form of the IP packets and an ATM network in which information are transmitted in a form of the ATM cells, the IP network having a hierarchy structure with an IP layer, the ATM network having a hierarchy structure with an AAL layer, the network interworking device comprising means for assembling a plurality of ATM cells in the ALL layer of the ATM network into an IP packet when the plurality of the ATM cells are to be transmitted to the same address in the IP communication network, the assembled IP packet being transmitted to the IP layer, and means for disassembling an IP packet in the IP layer of the IP network into a plurality of ATM cells, the disassembled ATM cells being transmitted to the AAL layer.
