TCP/IP over ATM’s
A real-time and Multimedia application which runs on Integrated Service Internet is rapidly becoming a reality. It is an important problem to integrate ATM networks into this Integrated Service Internet. A key remaining issue is to provide the quality of service guarantees for Internet traffic running through ATM subnets.
Data networking over the past twenty years has been the most successful concept of internetworking. It is a method for interconnecting networks. ATM technology is the emerging standard adopted by telecommunications. ATM delivers advantages over existing LAN and WAN technologies. ATM is a very complex technology and it is the most complex ever developed by the networking industry. IP over ATM is often preferred to LANE because it is faster than LANE. The advantage of TCP/IP over ATM’s is that it adds almost no additional header information to packets as they are handed down the stack. Once the connection is made, the IP over ATM client can generally transfer data without modification.

TCP/IP was first defined by Cerf and Khan in 1974. The design philosophy was discussed by Clark in 1988.

Not present in the model




The TCP/IP model and protocols have their problem too.
• The model does not clearly distinguish the concepts of service, interface and protocol.
• The TCP/IP is poorly situated to describe any protocol stack other than TCP/IP.
• The host-to-network is not really a layer. It is an interface between the network and data link layers.
• The TCP/IP does not distinguish the physical and data link layers.
