  • Page 9: Chapter 1 Introduction

    Chapter 1 Introduction The 9A426-01 ATM SmartSwitch Module is a hardware-based switching module that supports multiple interfaces simultaneously. The module’s interconnecting interfaces include: • A front panel ATM interface via a user-installed ATM Port Interface Module (APIM) • A fixed interface to the SmartSwitch 9000 Internal Network Bus (INB) •...

    Introduction Conversely, canonical frames destined for the FNB bus on the SmartSwitch 9000 backplane are converted into FDDI packets via the 9A426-01 Module’s FDDI Network Interface Block (FNIB), and then forwarded onto the FNB. Canonical frames destined for the INB bus on the SmartSwitch 9000 backplane are converted into fixed length data packets via the 9A426-01 Module’s INB Network Interface Block (INB NIB), and then forwarded onto the INB.
  • Page 11 Introduction Redundancy To ensure the transmission of data from a 9A426-01 Module to an ATM backbone, the module offers an additional “redundant” front panel port. Redundancy can be achieved by inserting a second APIM in the module’s front panel APIM port, connecting cables to that APIM, and enabling the redundancy feature via SNMP (network management) of the module (you can also disable redundancy via network management).
  • Page 12 Introduction If the module’s redundant link and primary link are two different physical ATM NOTE switches, the module will receive a new ATM address. Although the actual physical switch (from primary to redundant link) performed by the module is nearly immediate, the amount of time required to re-establish full communications varies according to factors associated with LANE 1.0 protocols and the performance/feature set of the user’s LANE services, but is typically less than one minute.

  • Page 37: Lan Emulation

    Operation LAN Emulation The 9A426-01 Module interconnects LANs over an ATM network through a method known as LAN Emulation. LAN Emulation, or LANE, is a method that makes a connection-orientated ATM network look and behave like a shared connectionless Ethernet or Token Ring LAN Segment. Unlike other methods of interconnecting LANs over ATM, LANE can handle routable protocols such as TCP/IP, IPX and DECNet, as well as non-routable protocols such as NetBlOS and SNA.
