Abstract
This memo describes a proposed MIB for the PINT Services
Architecture.
Status of this Memo
This document is an Internet-Draft and is in full conformance with
all provisions of Section 10 of RFC 2026. Internet-Drafts are working
documents of the Internet Engineering Task Force (IETF), its areas,
and its working groups. Note that other groups may also distribute
working documents as Internet- Drafts.
Internet-Drafts are draft documents valid for a maximum of six months
and may be updated, replaced, or obsoleted by other documents at any
time. It is inappropriate to use Internet Drafts as reference
material or to cite them other than as "work in progress."

1. Introduction
PINT services are an emerging set of new Internet based applications
where voice (and fax) requests to the PSTN (Public Switched Telephone
Krishnaswamy, Romascanu [Page 1]
Internet Draft PINT MIB September 2000
Network) are carried over the Internet. RFC 2458 [1] gives a good
introduction to the (pre-standard) PINT architecture and services.
It also has examples of some of the early implementations of pre-
PINT.
This document defines a MIB which contains the elements for
monitoring the performance of a PINT based service. The MIB consists
of details of the four basic PINT services and their performance
statistics measured under various criteria.
It is not the purpose of this MIB to enable management of the PINT
networking elements. We are concerned only with the PINT specific
performance parameters. While it is understood that PINT service
performance is closely related to host and network performance, they
are not addressed here.
2. The SNMP Management Framework
The SNMP Management Framework presently consists of five major
components:
o An overall architecture, described in RFC 2571 [2].
o Mechanisms for describing and naming objects and events for the
purpose of management. The first version of this Structure of
Management Information (SMI) is called SMIv1 and described in
RFC 1155 [3], RFC 1212 [4] and RFC 1215 [5]. The second version,
called SMIv2, is described in RFC 2578 [6], RFC 2579 [7] and RFC
2580 [8].
o Message protocols for transferring management information. The
first version of the SNMP message protocol is called SNMPv1 and
described in RFC 1157 [9]. A second version of the SNMP message
protocol, which is not an Internet standards track protocol, is
called SNMPv2c and described in RFC 1901 [10] and RFC 1906 [11].
The third version of the message protocol is called SNMPv3 and
described in RFC 1906 [11], RFC 2572 [12] and RFC 2574 [13].
o Protocol operations for accessing management information. The
first set of protocol operations and associated PDU formats is
described in RFC 1157 [9]. A second set of protocol operations
and associated PDU formats is described in RFC 1905 [14].
o A set of fundamental applications described in RFC 2573 [15] and
the view-based access control mechanism described in RFC 2575
Krishnaswamy, Romascanu [Page 2]
Internet Draft PINT MIB September 2000
[16].
A more detailed introduction to the current SNMP Management Framework
can be found in RFC 2570 [17].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using the mechanisms defined in the SMI.
This memo specifies a MIB module that is compliant to the SMIv2. A
MIB conforming to the SMIv1 can be produced through the appropriate
translations. The resulting translated MIB must be semantically
equivalent, except where objects or events are omitted because no
translation is possible (use of Counter64). Some machine-readable
information in SMIv2 will be converted into textual descriptions in
SMIv1 during the translation process. However, this loss of machine
readable information is not considered to change the semantics of the
MIB.
3. The need for PINT services monitoring MIB
Traditionally voice (and fax) requests originate and terminate inside
a PSTN network. This network is well known for robust handling of the
requests, in terms of availability and security. However when the
requests originate from the Internet there is a concern both on the
part of the user as well as the provider about issues like reliable
forwarding of the call requests to the PINT gateway under various
network conditions, user/host authentication, secure handling of the
user information etc. Performance and security management becomes
all the more important where PINT services cross multiple
administrative domains (or providers).
This MIB is an attempt to list the parameters that need to be
monitored on an user, PINT client, PINT server and PINT gateway basis.
(PINT services, their invocation methods/protocols and security
issues associated with the PINT architecture are discussed in detail
in [18]).
4. PINT MIB - Overview
Following is a list of some explanations on the MIB definitions that
Krishnaswamy, Romascanu [Page 3]
Internet Draft PINT MIB September 2000
we have chosen to construct.
o The basic purpose of this MIB is to monitor the access to PINT
services both from the performance and security point of view.
Information may pertain to a certain user or his/her system
(PINT client) or the system providing the PINT services (PINT
server) or the PINT gateway that forwards the call to the PSTN
network.
o We propose to build the configuration table as an extension of
the Application MIB - RFC 2287 [19] using the augments clause.
Server location and contact might be retrieved from the
standard MIB-II sysLocation and sysContact objects. There is no
need to replicate this information in the PINT MIB. However, the
PINT administrator may be a different person than the sysadmin
with global responsibilities, thus a pintSysContact object is
defined.
o We chose to monitor the gateway connections from the PINT
server. While the agent runs in the PINT servers, the links
to the gateways might need to be monitored in order to
understand what goes on. We placed them in a separate MIB group,
and by using MODULE-COMPLIANCE clauses, agents that cannot
implement this stuff will not be mandated to do it.
o There is no traps definition in this preliminary proposal. Note
that thresholding on counters is always possible by using a
standard mechanism defined by the Remote Monitoring MIB, that
can be referenced here. Some events that may be defined by using
this mechanisms:
* continuous login/authentication failure or refusal from a
particular client or user
* nuisance call - repeated calls (within a specified period)
to a number originating from the same user
o The client performance and user performance tables may be rather
resource demanding for an agent implementation. In some MIBs,
like the Remote Monitoring (RMON) MIBs, control mechanisms were
built in order to activate those statistics on demand. If
needed, a sorting ('topN') mechanism can be designed, so that a
sorted view of clients or users is presented for the high level
Krishnaswamy, Romascanu [Page 4]
Internet Draft PINT MIB September 2000
debugging.
o We built a time-distribution trying to cover both short-lived,
as well as longer sessions (1-10 secs, 10 secs - 1 min., 1-15
min., 15 mins-24 hours, longer).
o PintServerClientAddress is defined as a SnmpAdminString. It may
include an IpAddress and/or name, but we preferred to minimize
the number of indices at this stage, and keep a human-readable
format at the same time.
o We define pintServerUserIdName as the UserId. This UserId needs
to be unique across multiple PINT servers and gateways depending
on the architecture, and is mapped to the SessionId. One
way to achieve this uniqueness is by appending clientId to the
UserId string before sending to the PINT server. The SessionId
could then be a combination of this new UserId and a timestamp.

7. Security Considerations
There is only one management object defined in this MIB that has a
MAX-ACCESS clause of read-write (pintSysContact). There are no read-
create objects. This read-write object may be considered sensitive or
vulnerable in some network environments. The support for SET opera-
tions in a non-secure environment without proper protection can have
a negative effect on network operations.
There are a number of managed objects in this MIB that may contain
information that may be sensitive from a business perspective. One
could be the customer identification (UserIdName). Also information
on PINT services performance might itself be need to be guarded. It
is thus important to control even GET access to these objects and
possibly to even encrypt the values of these object when sending them
over the network via SNMP. Not all versions of SNMP provide features
for such a secure environment.
SNMPv1 by itself is not a secure environment. Even if the network
itself is secure (for example by using IPSec), even then, there is no
control as to who on the secure network is allowed to access and
GET/SET (read/change/create/delete) the objects in this MIB.
It is recommended that the implementers consider the security
Krishnaswamy, Romascanu [Page 17]
Internet Draft PINT MIB September 2000
features as provided by the SNMPv3 framework. Specifically, the use
of the User-based Security Model RFC 2574 [13] and the View- based
Access Control Model RFC 2575 [16] is recommended.
It is then a customer/user responsibility to ensure that the SNMP
entity giving access to an instance of this MIB, is properly config-
ured to give access to the objects only to those principals (users)
that have legitimate rights to indeed GET or SET (change/cre-
ate/delete) them.
8. IANA Considerations
All extensions to the values listed in this MIB must be done through
Standards Action processes as defined in RFC 2434 [21].
