Abstract
This memo defines managed objects for packet sampling. These objects
provide information about managed nodes supporting packet sampling,
including packet sampling capabilities, configuration and statistics.
They also allow to configure packet sampling concerning the IP
interface at which packets are sampled, the packet selections methods
used for sampling, and the collector to which packet samples are
exported.

Internet-Draft PSAMP MIB February 2004
1. Introduction
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].
This document is a product of the Packet Sampling (PSAMP) working
group. Its purpose is to define standards-based MIB modules for
monitoring and configuring managed nodes performaing packet sampling.
It is assumed that packet sampling is performed according to the
framework defined in [I-D.ietf-psamp-framework]. Packet selection
methods considered in the MIB module are specified in
[I-D.ietf-psamp-sample-tech]. Configuration of the export of samples
to a collector is modeled according to [I-D.ietf-psamp-protocol].
Section 3 describes the structure of the PSAMP MIB module and section
4 contains the formal definition. Security issues are discussed in
section 5.
2. The Internet-Standard Management Framework
For a detailed overview of the documents that describe the current
Internet-Standard Management Framework, please refer to section 7 of
RFC 3410 [RFC3410].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. MIB objects are generally
accessed through the Simple Network Management Protocol (SNMP).
Objects in the MIB are defined using the mechanisms defined in the
Structure of Management Information (SMI). This memo specifies a MIB
module that is compliant to the SMIv2, which is described in STD 58,
RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
[RFC2580].
3. Structure of the PSAMP MIB module
This draft does still not contain a complete PSAMP MIB module
definition, but some essential components of it sketching the
structure of the complete module. The sketch serves as input to a
discussion of the MIB module structure, particular of the modelling
of capabilities and configured packet sampling instances. Please find
a (not complete) list of open issues at the end of the document.
The PSAMP-MIB module defined below contains four groups of objects:
the sampling methods group, the filtering methods group, the
reporting group, and the instances group.
Dietz, et al. draft-ietf-psamp-mib-02.txt [Page 3]
Internet-Draft PSAMP MIB February 2004
3.1 The Sampling Methods Group
The first group of objects contains information about sampling
methods. Each sampling method is covered by an individual sub-tree of
this group. For each method, the following objects are defined: a
single object indicating the availability of the method, a sub-group
of objects indicating specific capabilities and limits of the method,
and a sub-group specifying sets of parameters. Each parameter set
uniquely specifies all paramerters of a packet sampling instance of
the method.
Methods and parameters of methods are specified in
[I-D.ietf-psamp-sample-tech]. So far, objects for six methods defined
in this Internet drafts are contained in the PSAMP MIB module plus an
additional trivial method. Further methods need to be added later and
some of the existing methods need to be elaborated because they are
just placeholders for the final objects. The seven methods are
selecting all, systematic count-based sampling, systematic time-based
sampling, random n-out-of-N sampling, random uniform probabilistic
sampling, random non-uniform probabilistic sampling and flow state
sampling.
All methods contain a pointer (OID) to the next sampling method used
after the current sampling method. Thus concatenation of sampling
methods can be realized. Also all parameters sets contain a row
status. TBD: Define usage of RowStatus.
3.1.1 Selecting All Packets
This trivial packet selection method is alway available. If it is
applied, all packets will be selected.
3.1.2 Systematic Count-based Sampling
The first object in this group is
psampSystematicCountBasedSamplingAvailability indicating the
availability of this method. It is followed by a sub-group of objects
specifying capabilities. psampSystematicCountBasedSamplingMaxInterval
indicates the maximum sampling interval in packets supported by the
implementation, psampSystematicCountBasedSamplingMaxSpacing indicates
the maximum spacing in packets supported by the implementation.
Finally psampSystematicCountBasedSamplingParameterSetTable contains a
parameter set in each of its entries that completely specifies a
configuration of an instance of the packet sampling method. These
parameter sets are not necessarily instantiated at the managed node,
but for each instanciated paramter set of this method, there MUST be
an entry in this table. The parameter set contains two parameters:
Dietz, et al. draft-ietf-psamp-mib-02.txt [Page 4]
Internet-Draft PSAMP MIB February 2004
the sampling interval length and the spacing specified in numbers of
packets.
3.1.3 Systematic Time-based Sampling
The first object in this group is
psampSystematicTimeBasedSamplingAvailability indicating the
availability of this method. It is followed by a sub-group of objects
specifying capabilities. psampSystematicTimeBasedSamplingMaxInterval
indicates the maximum sampling interval in microseconds supported by
the implementation, psampSystematicTimeBasedSamplingMaxSpacing
indicates the maximum spacing in microseconds supported by the
implementation.
Finally psampSystematicTimeBasedSamplingParameterSetTable contains a
parameter set in each of its entries that completely specifies a
configuration of an instance of the packet sampling method. These
parameter sets are not necessarily instantiated at the managed node,
but for each instanciated paramter set of this method, there MUST be
an entry in this table. The parameter set contains two parameters:
the sampling interval length and the spacing specified in
microseconds.
3.1.4 Random n-out-of-N Sampling
The first object in this group is
psampRandomOutOfNSamplingAvailability indicating the availability of
this method. So far, the sub-group of objects specifying capabilities
is empty for this method.
EDITOR NOTE: this must be changed since we somehow can define some
constraints now.
The psampRandomOutOfNSamplingParameterSetTable contains a parameter
set in each of its entries that completely specifies a configuration
of an instance of the packet sampling method. These parameter sets
are not necessarily instantiated at the managed node, but for each
instanciated paramter set of this method, there MUST be an entry in
this table. The parameter set contains two parameters. The first one
is psampRandomOutOfNSamplingPopulation and gives the number of
elements N in the parent population. The second
psampRandomOutOfNSamplingSize gives the number of elements n taken
from the parent population. With these two parameters you sample n
packets out of N.
Dietz, et al. draft-ietf-psamp-mib-02.txt [Page 5]
Internet-Draft PSAMP MIB February 2004
3.1.5 Random Uniform Probabilistic Sampling
The first object in this group is
psampRandomUniformProbabilisticSamplingAvailability indicating the
availability of this method. So far, the sub-group of objects
specifying capabilities is empty for this method.
EDITOR NOTE: this must be changed since we somehow can define some
constraints now.
The psampRandomUniformProbabilisticSamplingParameterSetTable contains
a parameter set in each of its entries that completely specifies a
configuration of an instance of the packet sampling method. These
parameter sets are not necessarily instantiated at the managed node,
but for each instanciated paramter set of this method, there MUST be
an entry in this table. The parameter set contains two parameters.
The first one is psampRandomUniformProbabilisticSamplingPopulation
and gives the number of elements N in the parent population. The
second psampRandomUniformProbabilisticSamplingSize gives the number
of elements n taken from the parent population.
EDITOR NOTE: we are missing the description for the functional
difference to n-out-of-N sampling.
3.1.6 Random Non-Uniform Probabilistic Sampling
The first object in this group is
psampRandomNonUniformProbabilisticSamplingAvailability indicating the
availability of this method. So far, the sub-group of objects
specifying capabilities is empty for this method.
EDITOR NOTE: The parameter set table is also still empty and has to
done.
3.1.7 Flow State Sampling
The first object in this group is psampFlowStateSamplingAvailability
indicating the availability of this method. So far, the sub-group of
objects specifying capabilities is empty for this method.
EDITOR NOTE: The parameter set table is also still empty and has to
done.
3.2 The Filtering Methods Group
The second group contains information about the filtering methods.
This group is build up similarly to the sampling methods group. It
currently contains three filtering methods, the mask filtering, the
Dietz, et al. draft-ietf-psamp-mib-02.txt [Page 6]
Internet-Draft PSAMP MIB February 2004
hash filtering and the router state filtering.
3.2.1 Mask Filtering
to be done...
3.2.2 Hash Filtering
The first object in this group is psampHashFilteringAvailability
indicating the availability of this method. So far, the sub-group of
objects specifying capabilities is empty for this method.
EDITOR NOTE: The capabilites should somehow say what hash functions
are available.
The psampHashFilteringParameterSetTable contains a parameter set in
each of its entries that completely specifies a configuration of an
instance of the packet filtering method. These parameter sets are not
necessarily instantiated at the managed node, but for each
instanciated parameter set of this method, there MUST be an entry in
this table. The parameter set contains one parameters, the
psampHashFilteringFunction contains an object ID poiting to the hash
function used.
3.2.3 Router State Filtering
to be done...
3.3 The Reporting Group
The reporting group of managed objects provides information on
collectors to which sampled packets are exported and they allow to
configure collectors.
The group contains a three tables, the psampCollectorTable, the
psampCollectorGroupTable and the psampTemplateTable. Each entry in
the psampCollectorTable specifies a collector by its IP address, used
transport protocol and port number. Also it contains the number of
reports sent to this collector. The psampCollectorGroupTable groups
one or more collectors to a set of collectors where sampled packets
are sent to. Thus reporting to more than one collector at the same
time is possible. The psampTemplateTable list all templates that are
used by the PSAMP exporter.
EDITOR NOTE: The table must be completed and the templates must be
somehow linked to the collector and an instance.
Dietz, et al. draft-ietf-psamp-mib-02.txt [Page 7]
Internet-Draft PSAMP MIB February 2004
3.4 The Instance Group
The instance group of managed objects provides information about
active packet sampling instances at the managed node. It also allows
to create new instances and to terminate them.
The group contains a single table, the psampInstanceTable. Each
entry of this table describes an instance by the IP interface it is
acting at, by the packet selection methods it is executing, and by
the collector to which reports on sampled packets are sent.
Furthermore a start and stop time can be given when the sampling
method should run.
Each method is specified by a reference to a method-specific
parameter set. This parameter set also defines a concatenated list of
sampling methods if supported. Collectors are specified by an index
of the psampCollectorGroupTable.
The following statistics is available for each instance: number of
packets observed by the method.

5. Security Considerations
There are a number of management objects defined in this MIB module
with a MAX-ACCESS clause of read-write and/or read-create. Such
objects may be considered sensitive or vulnerable in some network
environments. The support for SET operations in a non-secure
environment without proper protection can have a negative effect on
network operations. These are the tables and objects and their
sensitivity/vulnerability:
To be done.
6. Open Issues
o describe row status objects to writable tables
o support for reporting from a single instance to multiple
collectors may be refined
o elaborate conformance statements
o complete security considerations
o observed packets may be expanded to number of packets before
sampling and after sampling or something similar.
o align wording with the other draft documents (e.g. instance vs.
selector)
Dietz, et al. draft-ietf-psamp-mib-02.txt [Page 31]
Internet-Draft PSAMP MIB February 2004
o finish template table and link it with the other elements.
o implement observation point for the sampling/filtering methods.
o restrict MIB names to 32 characters
o ...
