book Page 1 Thursday, April 18, 1996 2:18 PM APPENDIX B ATM OVERVIEW This Appendix covers basic Asynchronous Transfer Mode (ATM) network operation and concepts that are critical to ATM network design and installation. The ATM Forum User-Network Interface Specification provides greater detail on ATM access methods and should be referenced whenever more information is needed. The scope of this appendix is to provide information regarding: • Basic ATM Concepts. • Basic ATM technology and how it works. B.
book Page 2 Thursday, April 18, 1996 2:18 PM Appendix B: ATM Overview B.2 THE ATM CELL One major difference between ATM and current transmission methods is that instead of using variable-length packets, ATM transmits fixed-size cells. (See Figure B-1.) Header Data 5 Bytes 48 Bytes Figure B-1 ATM Cells ATM uses three types of cells – Assigned, Unassigned, and Idle. Assigned cells carry actual traffic. Unassigned cells are free and waiting to be assigned traffic.

book Page 4 Thursday, April 18, 1996 2:18 PM Appendix B: ATM Overview B.3 THE ATM NETWORK ATM is a connection-oriented transmission technology. This means that no information transfers prior to establishing connection between devices. When preparing information, ATM uses Virtual Channels and Virtual Paths as cell addresses and places this channel data into the cell header.
book Page 5 Thursday, April 18, 1996 2:18 PM ATM Protocol B.3.2 PERMANENT AND SWITCHED VIRTUAL CHANNELS ATM networks use two different types of Virtual Channels – Permanent Virtual Channels (PVCs) or Switched Virtual Channels (SVCs). The difference between PVCs and SVCs exists in the channel set-up. PVCs are pre-configured by an administration function, and are usually established for long term use.
book Page 6 Thursday, April 18, 1996 2:18 PM Appendix B: ATM Overview When a message is sent out by a user: • It passes from the highest layer in the model, the Applications Layer, down to the lowest layer, the Physical Layer. • The Physical Layer physically transmits the message over a particular media. When this message reaches its destination: • It passes upward, in the reverse order, from the Physical Layer to the Applications Layer.
book Page 7 Thursday, April 18, 1996 2:18 PM ATM Protocol ATM provides the function of the first three layers of the OSI model, but performs all the information routing (cell switching) in only the Physical and Data Link Layer. Performing the information routing functions in the Physical and Data Link layers essentially bypasses the Network Layer. This allows ATM to process cells much quicker and more efficiently than packet-based routing.
book Page 8 Thursday, April 18, 1996 2:18 PM Appendix B: ATM Overview Layer 3: The ATM Adaptation Layer vs. The Network Layer Even though these two layers have the same “physical” location in their perspective models, they are not alike. In the OSI model, the Network Layer formats data to be sent out on a particular network (for example, IP, or IPX).
