      Managed Objects for ATM over Packet Switched Networks (PSNs)

Abstract

   This memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols in the Internet community.
   In particular, it describes managed objects for modeling ATM
   Pseudowire (PW) carrying ATM cells over Packet Switched Networks
   (PSNs).

Status of This Memo

   This document specifies an Internet standards track protocol for the
   Internet community, and requests discussion and suggestions for
   improvements.  Please refer to the current edition of the "Internet
   Official Protocol Standards" (STD 1) for the standardization state
   and status of this protocol.  Distribution of this memo is unlimited.

1.  Introduction

   This document describes a model for managing "emulated" ATM services
   over a Packet Switched Network (PSN).

   The document follows the requirements for Pseudowire Emulation Edge-
   to-Edge [PWREQ]; it is closely related to [ATMENCAP] and [ATMTRANS],
   which describe the encapsulation of ATM signals and provide the
   Emulation Service over a Packet Switched Network.

   The ATM management model consists of several MIB modules, following
   the layering model described in the PWE3 Architecture [PWARCH]
   document.  The ATM MIB module described in this document works
   closely with the MIB modules described in [AToMTC], [AToM], [IFMIB],
   [PWMIB], and the textual conventions defined in [PWTC].  The
   conceptual layering and relationship among all of those is described
   in Figure 1 and in the "Relation to Other PW-MIB Modules" section
   listed below.  An ATM connection will be a pseudowire (PW)
   connection.  It will not be treated as an interface and will
   therefore not be represented in the ifTable.
