E-IISP also introduced the concept of hierarchy in a network design. Using E-IISP Network E-IISP, most 3Com ATM networks are based in the ATM address of 47.0.0.0.0.0.3c.0.0.a* that is, utilizing the last four bytes of the switch portion of the ATM address.

Switches receives the message and stores the received network prefix together with the port number on which the message was received. In this way, each CoreBuilder 9000 ATM Enterprise Switch knows the network prefix of each of its neighbors.

Page 345: Automatic Retry
E-IISP Hierarchic Routing Algorithm Automatic Retry After receiving the RELEASE message, the source CoreBuilder 9000 ATM Enterprise Switch again attempts to establish a virtual channel, but this time via an alternate path. The switch determines the alternate path automatically with the routing table that was established during the first connection attempt.
Page 346 12: E-IISP P HAPTER ROTOCOL Alternate routes are desirable for the following reasons: Dividing the load between nodes over several links reduces congestion (see next section) If one link fails, an alternate link can be used. If the node cannot be found or accessed via a link, it can be searched through another link after crankback.
Page 347: Load Balancing
(For more information, see “E-IISP Hierarchic Routing Algorithm” on page 368.) If two or more NNI neighbors have the same match type, the CoreBuilder 9000 ATM Enterprise Switch uses its routing table to assign a connection to each of the links in a round robin algorithm; the first connection to the first link, the second connection to the second link, and so on.

Page 349: Establishing Atm Channels
ATM C STABLISHING HANNELS Asynchronous Transfer Mode (ATM) is a connection-oriented transport service, much like a telephone. Unlike Ethernet, where data is sent out on a common bus, ATM requires that a path or virtual channel be established to carry the call from the source station to the destination station before data transmission can begin.
Page 350: Virtual Channels
13: E ATM C HAPTER STABLISHING HANNELS Virtual Channels A virtual channel is a communications path that can carry a single call from the source station to the destination station. A channel is virtual because it does not necessarily correspond to a single physical line and, in fact, usually passes through many different network devices and cables before reaching its destination.
Page 351 Virtual Channels The figure shows three ATM devices: two ATM edge devices and an ATM Enterprise Switch between them. The virtual channel begins at the left edge device, passes through the ATM Enterprise Switch and terminates at the right edge device.

Signaling — External Links A point-to-multipoint call has the following properties: The source end point serves as the root in a simple tree topology. When this link node sends information, all of the remaining nodes on the call receive copies of the information. Data flows only from the root to the destination nodes.

Page 435: Protocols And Interfaces
ROTOCOLS AND NTERFACES This appendix describes basic concepts and information about interfaces and management protocols that are used in the ATM system including the following topics: Physical Layer Interfaces ATM Layer Operation and Maintenance (OAM) ATM Adaptation Layer (AAL) Physical Layer Traditionally, the physical layer deals with bits and its function is to move a Interfaces bit from place to place.
Page 436 C: P PPENDIX ROTOCOLS AND NTERFACES Cell Delineation: This function permits the identification of cell boundaries in the payload. It uses the Header Error Control (HEC) field in the cell header. Path Signal Identification: An integrity check is performed on the end-to-end signal.
Page 437: Physical Layer Interface
Physical Layer Interfaces DS-3 Physical Layer DS-3 is an important interface because it is widely deployed on public UNIs. Although the DS-3 rate is 44.76 Mbps, the nominal bit rate that is Interface available for the transport of ATM cells is 40.704 Mbps. This is due to the overhead induced by the Physical Layer Convergence Protocol (PLCP).
Page 438: Atm Layer
C: P PPENDIX ROTOCOLS AND NTERFACES ATM Layer This section presents the structure of the ATM cell and ATM layer. ATM Cell Structure The ATM cell is defined as 48 bytes of payload and 5 bytes of header information totaling 53 bytes. The header contains enough information to allow the network to forward each cell to its proper destination.
Page 439: The Atm Layer
ATM Layer Table 71 ATM Cell Header Fields (continued) Field Full Field Name Description Payload Type Identifier This is a 3 bit field used to indicate whether the cell contains user information or connection associated layer management information (F5 flow). The PTI is also used to indicate a network congestion state or for network resource management, and is used to mark the end of frame for AAL5 adaptation layer.
Page 440: Operation And Maintenance (Oam)
C: P PPENDIX ROTOCOLS AND NTERFACES The ATM layer supports fault management, including alarm surveillance and connectivity verification functions. OAM cells are used for exchanging operation related information. ATM cells with valid VPI/VCI values are discarded and Layer Management is informed. Traffic management at the public UNI monitors traffic on each connection and takes the proper action to protect the network resources and ensure that the user-network traffic agreements are respected.
Page 441 Operation and Maintenance (OAM) The virtual channel connection (VCC) operation information is carried via the F5 flow OAM cells. These cells have the same VPI/VCI values as the user-data cells but are identified by preassigned code points of the PT field.
Page 442: Atm Adaptation Layer (Aal)
C: P PPENDIX ROTOCOLS AND NTERFACES ATM Adaptation The role of the ATM Adaptation Layers (AALs) is to define how to deal Layer (AAL) with the contents of cells. The AAL performs Segmentation and Reassembly (SAR) on cells. It formats data into the 48 byte ATM cell payload, in effect adapting applications to the cell-based ATM layer.
Page 443: Aal5
ATM Adaptation Layer (AAL) AAL5 The AAL5 is the data-oriented adaptation layer. The CRC is appended to the end of the frame to protect the user information against bit and cell errors. It is padded to align to 48 bytes (Figure 35). To indicate frame boundaries and determine when to reassemble and when to stop reassembling, the space bit for Payload Type (PT) in the cell header is zero except for the last cell in the packet (when it is a one).
