Chapter 3: ATM Communications Protocols

1. Introduction

ATM provides a mechanism for communication between two end points within the context of a generalized protocol between the communicating entities. One example of such a communications protocol is the Open Systems Interconnection (OSI) reference model [1]. This model consists of seven layers, each layer providing a set of services to the next higher layer:

  1. Physical Layer-Concerned with transmission of a bit stream over a physical communications medium, including mechanical, electrical, functional, and procedural characteristics for access to the physical link.
  2. Data Link Layer-Provides reliable transfer of information across the physical link consisting of blocks that include data, synchronization, error control, and flow control information.
  3. Network Layer -Responsible for establishing, maintaining, and terminating connections while providing upper layers with independence from the data transmission and switching technologies used to connect end systems. The end-to-end connection between communicating applications supported by this layer may span multiple data links.
  4. Transport Layer-Provides reliable transfer of data between end points, including end-to-end error recovery and flow control.
  5. Session Layer -Responsible for establishing, maintaining, and terminating connections between communicating applications.
  6. Presentation Layer-Allows independence to applications from differences in data representation at the end-user terminal.
  7. Application Layer-The layer most visible to the end user, consisting of applications that perform information processing.
ATM is a technologythat spans the Physical and Data Link layers.

2. B-ISDN Protocol Reference Model (PRM)

The B-ISDN protocol reference model is defined in ITU-T Recommendation 1.321 and is shown in Figure 3-1 [2]. The B-ISDN PRM is a three dimensional model consisting of planes in the vertical dimension:

(Figure 3.1: B-ISDN protocol reference model.)

  1. Physical Layer -Corresponds to the Physical Layer in the OSI reference model.
  2. ATM Layer-This layer, which corresponds to the Data Link Layer in the OSI reference model, is responsible for the transparent transfer of fixed-size ATM cells between communicating higher layer entities.
  3. ATM Adaptation Layer (AAL) -Supports functions required by higher layer protocols, including mapping ATM cells to data packet formats used by those higher layer entities. While a Data Link layer protocol is generally concerned with communications over a single physical link between network nodes, the AAL performs its functions at the ends of an ATM connection, which may span multiple physical links. This gives the AAL a characteristic commonly associated with the Network Layer. Nevertheless, the primary functions performed at the AAL are Data Link functions: error detection, flow control, etc.
  4. Higher Layers-Incorporates some (but not necessarily all) of the functionality of OSI RM Layers 3 through 7.
At the top face of the cube shown in Figure 3-1 is a second set of planes:
  1. User Plane (U-plane) - As shown in Figure 3-1, the U-plane represents the set of functions that provide for the transfer of information between two communicating end points. The U-plane contains a Physical Layer, ATM Layer, and an ATM Adaptation Layer that performs the function required by the Higher Layers. In relation to the OSI RM, the Higher Layers of the U-plane represent OSI RM Layers 3 through 7. Communications supported by the U-plane operate within the context of connections that have been previously established. Functions performed within the U-plane play no role in the establishment and termination of connections.
  2. Control Plane (C-plane) -Connections between end points can be either permanent, or established on-demand. Functions performed in the C-plane provide for the on-demand establishment, and termination of connections between communicating end points. Higher Layers in the C-plane represent Network Layer functionality (such as routing) not performed by the Adaptation Layer.
  3. Management Plane (M-plane) - The M-plane is concerned with management of the C- and U-planes, including error monitoring and reporting, connection verification, and performance monitoring. The M- plane also provides for the establishment of permanent connections between communicating end points. The M-plane consists of two types of functions:
  • Layer Management: performs layer- specific management functions (e.g., monitoring of bit error rates on a physical communications medium).
  • Plane Management: performs management and coordination functions that span across layers (eg., establishment of a permanent connection).
The discussion in this chapter will focus on the U-plane. The operation of the C- plane will be discussed in the chapter on ATM Signalling, while M-plane operation will be discussed in the chapter on Operations, Administration, and Maintenance.

2.1 IB-ISDN Protocol Operation

Figure 3-2 presents a conceptual depiction of the B-ISDN Protocol. Since we are focusing on the portion of the protocol that involves ATM specifically, higher layers are not presented. The same conceptual notions, however, extend to the higher layer protocols.

(Figure 3-2: B-SISN protocol operation.)

In Figure 3-2, the Higher Layer Protocol sends a packet of data, or Protocol Data Unit (Higher Layer PDU), to the AAL by accessing a Service Access Point (SAP) for the AAL (the AAL-SAP). The AAL-SAP defines a set of functions and data structures (or, "primitives") that are passed between the AAL and the Higher Layer The SAP is uniquely addressed such that it corresponds to a specific connection between communicating Higher Layer entities. There may be one or more n-SAPs at the boundary between the Layer-n, and Layer-(n + 1) protocols.

At the AAL, the Higher Layer PDU becomes an AAL Service Data Unit (AAL- SDU) to which is appended an AAL-Header (and/or Trailer) containing information to support the functions performed by the AAL. Together the AAL-Header and/or Trailer, and AAL-SDU form the AAL-PDU The maximum size of the AAL-PDU, which may be of variable length, is determined at the time that a connection is established between communicating endpoints.

In a generic layered protocol discussion, this AAL-PDU is passed as a unit to the next lower protocol layer which, in turn, appends its own header. The ATM layer accepts PDUs of a fixed size of 48 octets. Thus, Figure 3-2 shows that the AAL divides the AAL-PDU into smaller PDUs, which are then passed to the ATM Layer across the ATM LayerSAP. Thus, the AAL Layer consists of two sublayers: a Convergence Sublayer (CS), which processes the Higher Layer PDU and appends an AAL Header; and a Segmentation and Reassembly (SAR), which divides the AAL-PDU into 48-octet SAR-PDUs at the originating end and, on the receiving end, reassembles the 48-octet units into the original AAL-PDU.

At the ATM Layer, a fixed 5-octet header is appended to SAR-SDU received across the ATM-SAP This forms a 53-octet ATM-PDU commonly referred to as a "cell."

At the Physical Layer the cell is encoded into a bit stream for transport across a physical transmission medium.

3. The Physical Layer

The Physical Layer is defined in ITU-T Recommendation 1.432, and in the ATM User-Network Interface Specification published by the ATM Forum [3][4]. At the time of this writing the ATM Forum had defined physical layer ATM interfaces for transmission rates ranging from 25.6 Mb/s to 622.08 Mb/s. The physical layer is functionally divided into two sublayers: the Physical Media Dependent (PMD) Sublayer, and the Transmission Convergence (TC) Sublayer.

3.1 Physical Media Dependent (PMD) Sublayer

The PMD sublayer deals with characteristics, which are dependent upon the physical medium used. These include:

  • Physical Medium Type: eg., Category 5 Universal Twisted Pair, Single Mode Optical Fiber, etc.
  • Bit Rate and Symmetry: the speed at which bits are carried over the medium and whether the bit rate is the same in both transmission directions.
  • Maximum Length of Physical Medium: depends upon the signal attenuation characteristics of the physical medium used.
  • Line Coding Method: eg., Coded Mark Inversion, Non Return to Zero, etc.

3.2 Transmission Convergence (TC) Sublayer

The TC sublayer addresses physical layer characteristics, which are independent of the physical medium used. The TC is dependent upon the transmission format used for sending information across the physical medium. Regardless of transmission format, certain characteristics are common to all formats:

  • Cell Delineation: the ability to distinguish individual ATM cells in the transmission frame-the method for accomplishing this, however, may vary for different transmission formats.
  • Cell Error Detection: the ability to detect, and possibly correct, bit errors in the ATM cell.
Other TC sublayer characteristics are specific to the transmission format used over the physical medium. Thus, as shown in Table 3-1, the TC sublayer functions for SONET are, for the most part, different from those of DS-3 [5] [6].
