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

Internet Draft SNANAU HPR MIB November 1996
devices with HPR (High Performance Routing) capabilities. This memo
identifies managed objects for the HPR protocol.
This memo does not specify a standard for the Internet community.
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 the proposed set of 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.
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
Expires May 19, 1997 [Page 2]
Internet Draft SNANAU HPR MIB November 1996
to restore the optimal path.
RTP performs flow/congestion control with the Adaptive Rate-Based (ARB)
algorithm. ARB is done only at the endpoints of the RTP pipe, so
intermediate hops are not involved. ARB regulates the flow of data over
an RTP connection by adaptively changing the sender's rate based on
feedback on the receiver's rate. It is designed to prevent congestion
rather than react to it.
In this document, we describe HPR managed objects.
The HPR terms and overall architecture are available from the
networking.raleigh.ibm.com ftp site [5].
Highlights of the management functions supported by the HPR MIB module
include the following:
o Identifying network connection endpoints (NCEs).
o Identifying how incoming packets are routed based on ANR labels.
o Monitoring the RTP connections between nodes supporting the HPR
Transport Tower.
o Ability to trigger an RTP path switch
o Historical information about RTP path switch attempts
This MIB module does not support:
o Configuration of HPR nodes.
o Protocol-specific uses of HPR (such as APPN)
o Traps. The APPN MIB contains a trap for Alert conditions that may
affect HPR resources.
4.1. HPR MIB Structure
The HPR MIB module contains the following groups of objects:
Expires May 19, 1997 [Page 3]
Internet Draft SNANAU HPR MIB November 1996
o hprGlobal - general HPR objects.
o hprAnrRouting - objects related to the ANR routing table.
o hprTransportUser - objects related to users of the HPR transport.
o hprRtp - objects related to the HPR Transport Tower.
These groups are described below in more detail.
4.1.1. hprGlobal group
The hprGlobal group consists of general objects such as the APPN CP name
of the HPR node and the level of support for operator-requested path
switches.
4.1.2. hprAnrRouting group
The hprAnrRouting group consists objects to monitor and control the
counting of ANR packets received and the following table:
1) hprAnrRoutingTable
This table correlates incoming ANR labels to the outbound transmission
group (TG) or local NCE to which incoming packet will be forwarded. An
entry defines the label type as identifying a local NCE or a TG,
identifies the NCE or TG, and counts the number of packets received with
the entry's ANR label.
4.1.3. hprTransportUser group
The hprTransportUser group consists of the following table:
1) hprNceTable
This table identifies network connection endpoints and their function
types. The function type can be any combination of a control point
(CP), logical unit (LU), boundary function, and route setup.
Expires May 19, 1997 [Page 4]
Internet Draft SNANAU HPR MIB November 1996
4.1.4. hprRtp group
The hprRtp group consists of the following objects and tables:
1) hprRtpGlobe
These objects contain information about the number of RTP connection
setups, and control of RTP counters.
2) hprRtpTable
This table contains one entry for each RTP connection. The information
includes local and remote NCE IDs and TCIDs, timers, send rates, and
statistics. A path switch can be triggered by the
hprRptPathSwitchTrigger object if the agent node supports it; however, a
new path cannot be specified.
3) hprRtpStatusTable
This table contains statistics and historical information for RTP path
switches attempts, including old and new ANR strings and Route Selection
Control Vectors (RSCVs), why the path switch was initiated, and the
result (successful or reason for failure).

-- The RTP Connection Status Table
-- This table contains statistics and historical information related to
-- both successful and unsuccessful RTP path switches. This information
-- can be important for both trend analysis and problem determination.
--
-- Note the terminology here: when RTP is triggered to find a new path
-- for a connection, this initiates a 'path switch,' which will end up
-- being either successful or unsuccessful. During this path switch,
-- RTP will make one or more 'path switch attempts,' which are attempts
-- to find a new path for the connection and switch the connection to
-- it. This 'new' path may be the same path that the connection was
-- using before the path switch.
--
-- It is an implementation option how many entries to keep in this
-- table, and how long to retain any individual entry.
