A Proposed Standard for the Transmission of
IP Datagrams over FDDI Networks
Status of this Memo
This RFC specifies a method of encapsulating the Internet Protocol
(IP)  datagrams and Address Resolution Protocol (ARP)  requests
and replies on Fiber Distributed Data Interface (FDDI) Networks.
This RFC specifies a proposed protocol standard for the Internet
community. Comments are welcome. Distribution of this memo is
This memo draws heavily in both concept and text from RFC 1042 ,
written by Jon Postel and Joyce K. Reynolds of USC/Information
The following language conventions are used in the items of
specification in this document:
"Must" or "Mandatory"--the item is an absolute requirement of the
"Should" or "Recommended"--the item should generally be followed
for all but exceptional circumstances.
"May" or "Optional"--the item is truly optional and may be
followed or ignored according to the needs of the implementor.
The goal of this specification is to allow compatible and
interoperable implementations for transmitting IP datagrams and ARP
requests and replies.
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)
, Physical Layer Protocol (PHY) , Physical Layer Medium
Dependent (PMD) , and Station Management (SMT) . The family of
FDDI standards corresponds to the IEEE 802 MAC layer standards [8, 9,
The remainder of the Data Link Service is provided by the IEEE 802.2
Logical Link Control (LLC) service . The resulting stack of
services appears as follows:
| IP/ARP |
| 802.2 LLC |
| FDDI MAC |
| FDDI PHY |
| 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.
IP datagrams and ARP requests and replies sent on FDDI networks must
be encapsulated within the 802.2 LLC and S...
