Transmission of IP and ARP over FDDI Networks

RFC 1390 IP Over FDDI January 1993
Introduction
The goal of this specification is to allow compatible and
interoperable implementations for transmitting IP datagrams [1] and
ARP requests and replies [2].
The Fiber Distributed Data Interface (FDDI) specifications define a
family of standards for Local Area Networks (LANs) that provides the
Physical Layer and Media Access Control Sublayer of the Data Link
Layer as defined by the ISO Open System Interconnection Reference
Model (ISO/OSI). Documents are in various stages of progression
toward International Standardization for Media Access Control (MAC)
[4], Physical Layer Protocol (PHY) [5], Physical Layer Medium
Dependent (PMD) [6], and Station Management (SMT) [7]. The family of
FDDI standards corresponds to the IEEE 802 MAC layer standards [8, 9,
10].
The remainder of the Data Link Service is provided by the IEEE 802.2
Logical Link Control (LLC) service [11]. The resulting stack of
services appears as follows:
+-------------+
| IP/ARP |
+-------------+
| 802.2 LLC |
+-------------+-----+
| FDDI MAC | F |
+-------------+ D S |
| FDDI PHY | D M |
+-------------+ I T |
| FDDI PMD | |
+-------------+-----+
This memo describes the use of IP and ARP in this environment. At
this time, it is not necessary that the use of IP and ARP be
consistent between FDDI and IEEE 802 networks, but it is the intent
of this memo not to preclude Data Link Layer interoperability at such
time as the standards define it.
It is the explicit intent of this memo to allow the interoperability
of IP and ARP between stations on FDDI networks and stations on
Ethernet networks via translational bridges.
The FDDI standards define both single and dual MAC stations. This
document describes the use of IP and ARP on single MAC stations
(single-attach or dual-attach) only.
