Abstract

This document describes the NBMA Address Resolution Protocol (NARP). NARP can be used by a source terminal (host or router) connected to a Non-Broadcast, Multi-Access link layer (NBMA) network to find out the NBMA addresses of the a destination terminal provided that the destination terminal is connected to the same NBMA network. Although this document focuses on NARP in the context of IP, the technique is applicable to other network layer protocols as well. This RFC is a product of the Routing over Large Clouds Working Group of the IETF.

NBMA Address Resolution Protocol (NARP)

Status of this Memo

This memo defines an Experimental Protocol for the Internet

community. This memo does not specify an Internet standard of any

kind. Discussion and suggestions for improvement are requested.

Distribution of this memo is unlimited.

IESG Note:

Note that the work contained in this memo does not describe an

Internet standard. This work represents an early stage in the

ongoing efforts to resolve direct communication over NBMA subnets.

It is a suitable experimental protocol for early deployment. It is

expect that it will be superceded by other work being developed

within the IETF.

Abstract

This document describes the NBMA Address Resolution Protocol (NARP).

NARP can be used by a source terminal (host or router) connected to a

Non-Broadcast, Multi-Access link layer (NBMA) network to find out the

NBMA addresses of the a destination terminal provided that the

destination terminal is connected to the same NBMA network. Although

this document focuses on NARP in the context of IP, the technique is

applicable to other network layer protocols as well. This RFC is a

product of the Routing over Large Clouds Working Group of the IETF.

1. Introduction

The NBMA Address Resolution Protocol (NARP) allows a source terminal

(a host or router), wishing to communicate over a Non-Broadcast,

Multi-Access link layer (NBMA) network, to find out the NBMA

addresses of a destination terminal if the destination terminal is

connected to the same NBMA network as the source.

A conventional address resolution protocol, such as ARP [1, 2] for

IP, may not be sufficient to resolve the NBMA address of the

destination terminal, since it only applies to terminals belonging to

the same IP subnetwork, whereas an NBMA network can consist of

multiple logically independent IP subnets (LISs, [3]).

Once the NBMA address of the destination terminal is resolved, the

source may either start sending IP packets to the destination (in a

connectionless NBMA network such as SMDS) or may first establish a

connection to the destination with the desired bandwidth and QOS

characteristics (in a connection oriented NBMA network such as ATM).

An NBMA network can be non-broadcast e...
