Integrated Services Management Information Base using SMIv2

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.

Abstract

This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in TCP/IP-based internets.
In particular, it defines objects for managing the the interface
attributes defined in the Integrated Services Model. Comments should
be made to the Integrated Services Working Group, int-serv@isi.edu.

1. The SNMPv2 Network Management Framework

The SNMPv2 Network Management Framework consists of four major
components. They are:

o RFC1441 which defines the SMI, the mechanisms used for
describing and naming objects for the purpose of
management.

o STD 17, RFC1213 defines MIB-II, the core set of managed
objects for the Internet suite of protocols.

o RFC1445 which defines the administrative and other
architectural aspects of the framework.

o RFC1448 which defines the protocol used for network
access to managed objects.

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

1.1. Object Definitions

Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using the subset of Abstract Syntax Notation One (ASN.1)
defined in the SMI. In particular, each object type is named by an
OBJECT IDENTIFIER, an administratively assigned name. The object
type together with an object instance serves to uniquely identify a
specific instantiation of the object. For human convenience, we
often use a textual string, termed the descriptor, to refer to the
object type.

2. Overview

2.1. Textual Conventions

Several new data types are introduced as a textual convention in this
MIB document. These textual conventions enhance the readability of
the specification and can ease comparison with other specifications
if appropriate. It should be noted that the introduction of the
these textual conventions has no effect on either the syntax nor the
semantics of any managed objects. The use of these is merely an

artifact of the explanatory method used. Objects defined in terms of
one of these methods are always encoded by means of the rules that
define the primitive type. Hence, no changes to the SMI or the SNMP
are necessary to accommodate these textual conventions which are
adopted merely for the convenience of readers and writers in pursuit
of the elusive goal of clear, concise, and unambiguous MIB documents.

2.2. Structure of MIB

The MIB is composed of the following sections:
Integrated Services
Interface Attributes Table
Interface Flow Table

Protocol"
::= { mib-2 52 }

intSrvNotifications OBJECT IDENTIFIER ::= { intSrv 3 }
intSrvConformance OBJECT IDENTIFIER ::= { intSrv 4 }

-- Textual Conventions
--

SessionNumber ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"The Session Number convention is used for
numbers identifying sessions or saved PATH or
RESV information. It is a number in the range
returned by a TestAndIncr variable, having no
protocol meaning whatsoever but serving instead
as simple identifier.

The alternative was a very complex instance or
instance object that became unwieldy."
SYNTAX INTEGER (0..2147483647)

Protocol ::= TEXTUAL-CONVENTION
DISPLAY-HINT "d"
STATUS current
DESCRIPTION
"The value of the IP Protocol field of an IP
Datagram Header. This identifies the protocol
layer above IP. For example, the value 6 is
used for TCP and the value 17 is used for UDP.
The values of this field are defined in the As-
signed Numbers RFC."
SYNTAX INTEGER (1..255)

SessionType ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"The value of the C-Type field of a Session ob-
ject, as defined in the RSVP specification.
This value determines the lengths of octet
strings and use of certain objects such as the
'port' variables. If the C-Type calls for an
IP6 address, one would expect all source, des-

tination, and next/previous hop addresses to be
16 bytes long, and for the ports to be UDP/TCP
port numbers, for example."
SYNTAX INTEGER (1..255)

Port ::= TEXTUAL-CONVENTION
DISPLAY-HINT "d"
STATUS current
DESCRIPTION
"The value of the UDP or TCP Source or Destina-
tion Port field, a virtual destination port or
generalized port identifier used with the IPSEC
Authentication Header or Encapsulating Security
Payload, or other session discriminator. If it
is not used, the value should be of length 0.
This pair, when coupled with the IP Addresses
of the source and destination system and the IP
protocol field, uniquely identifies a data
stream."
SYNTAX OCTET STRING (SIZE(2..4))

MessageSize ::= TEXTUAL-CONVENTION
DISPLAY-HINT "d"
STATUS current
DESCRIPTION
"The size of a message in bytes. This is used
to specify the minimum and maximum size of a

SYNTAX INTEGER (0..'7FFFFFFF'h)

BitRate ::= TEXTUAL-CONVENTION

STATUS current
DESCRIPTION
"The rate, in bits/second, that data may move
in the context. Applicable contexts minimally
include the speed of an interface or virtual
circuit, the data rate of a (potentially aggre-
gated) data flow, or the data rate to be allo-
cated for use by a flow."
SYNTAX INTEGER (0..'7FFFFFFF'h)

BurstSize ::= TEXTUAL-CONVENTION
DISPLAY-HINT "d"
STATUS current
DESCRIPTION

"The number of octets of IP Data, including IP
Headers, that a stream may send without concern
for policing."

4. Security Considerations

The use of an SNMP SET results in an RSVP or Integrated Services
reservation under rules that are different compared to if the
reservation was negotiated using RSVP. However, no other security
considerations exist other than those imposed by SNMP itself.
