ATM Administration
9
This chapter describes how to set up a connection to an Asynchronous Transfer
Mode (ATM) network.
ATM is a connection-oriented network protocol. To use this protocol, two
communicating entities must establish a connection before data transfer can
begin. TCP/IP, on the other hand, is inherently connectionless.
The SunATM™ 2.0 software supports two protocols which reconcile the
differences between the ATM and TCP/IP paradigms:
• Classical Internet Protocol (IP) interface
• LAN Emulation interface
Both these protocols allow TCP/IP to run transparently over an ATM interface
by resolving an IP address to an ATM address and establishing the connection
to the host to which a message is addressed.
The Netra ATM administration module supports SunATM version 2.0 software
and SunATM-155 version 2.0 hardware. (The SunATM-155/Mfiber SBus
Adapter 2.0 and SunATM-155/UTP5 SBus Adapter 2.0 are single-wide SBus
adapters that conform to the specifications of the ATM Forum.)
