2.  Introduction

   This memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols in the Internet community.
   In particular, it defines objects for monitoring and controlling
   network devices with HPR (High Performance Routing) capabilities.
   This memo identifies managed objects for the HPR protocol.

3.  The SNMP Network Management Framework

   The SNMP Network Management Framework consists of several components.
   For the purpose of this specification, the applicable components of
   the Framework are the SMI and related documents [1, 2, 3], which
   define the mechanisms used for describing and naming objects for the
   purpose of management.

   The Framework permits new objects to be defined for the purpose of
   experimentation and evaluation.

4.  Overview

   This document identifies objects for monitoring the configuration and
   active characteristics of devices with HPR capabilities.  HPR is an
   enhancement to the Advanced Peer-to-Peer Network (APPN) architecture
   that provides fast data routing and improved session reliability.
   APPN is one of the protocols that can use the HPR transport
   mechanism.  See the SNANAU APPN MIB [4] for management of APPN and
   APPN use of the HPR transport.

   The HPR terms and overall architecture [5] are available at
   http://www.networking.ibm.com/app/aiwdoc/aiwsrc.htm.

   Automatic Network Routing (ANR) is a fast low-level routing
   technique.  Each node assigns a unique (within that node) ANR label
   for each out-bound link as it is activated.  The label size is
   defined by the ANR node, and nodes only need to know how to interpret
   their own labels.  The ANR string is a group of ANR labels encoded in
   a header in front of the message being sent.  At each hop the node
   strips off its own ANR label and forwards the message onto the link
   with that label.  The last label in the string is the Network
   Connection Endpoint (NCE), which identifies the component within the
   destination node that is to receive the message.

   Rapid Transport Protocol (RTP) is an end-to-end full duplex transport
   connection (pipe).  It provides for high-speed transport of data
   using ANR.  RTP is connection-oriented, and delivers data in correct
   order reliably.  Error recovery is done efficiently with selective
   retransmission of data.  An RTP path can be switched without
   disrupting the sessions using it.  An RTP path switch may be done
   automatically if a link in the path fails and another RTP path is
   available, or on demand to attempt to restore the optimal path.

   RTP performs flow/congestion control with the Adaptive Rate-Based
   (ARB) algorithm, described in [5]. ARB is done only at the endpoints
   of the RTP pipe, so intermediate hops are not involved.
