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 Inter-Domain Policy
Routing Protocol [10,11].

This memo does not specify a standard for the Internet community.
However, after experimentation, if sufficient consensus is reached in the
Internet community, then a subsequent revision of this document may be
incorporated into the Internet-standard MIB.


1  Historical Perspective

As reported in RFC 1052, ``IAB Recommendations for the Development of
Internet Network Management Standards'' [1], a two-prong strategy for
network management of TCP/IP-based internets was undertaken.  In the
short-term, the Simple Network Management Protocol (SNMP), defined in RFC
1067, was to be used to manage nodes in the Internet community.  In the
long-term, the use of the OSI network management framework was to be
examined.  Two documents were produced to define the management
information:  RFC 1065, which defined the Structure of Management
Information (SMI), and RFC 1066, which defined the Management Information
Base (MIB). Both of these documents were designed so as to be compatible
with both the SNMP and the OSI network management framework.

This strategy was quite successful in the short-term:  Internet-based
network management technology was fielded, by both the research and
commercial communities, within a few months.  As a result of this,

Internet Draft                    IDPR MIB                   October 1993


portions of the Internet community became network manageable in a timely
fashion.

As reported in RFC 1109, Report of the Second Ad Hoc Network Management
Review Group [2], the requirements of the SNMP and the OSI network
management frameworks were more different than anticipated.  As such, the
requirement for compatibility between the SMI/MIB and both frameworks was
suspended.  This action permitted the operational network management
framework, based on the SNMP, to respond to new operational needs in the
Internet community by producing MIB-II.

In May of 1990, the core documents were elevated to "Standard Protocols"
with "Recommended" status.  As such, the Internet-standard network
management framework consists of:  Structure and Identification of
Management Information for TCP/IP-based internets, RFC 1155 [3], which
describes how managed objects contained in the MIB are defined;
Management Information Base for Network Management of TCP/IP-based
internets, which describes the managed objects contained in the MIB, RFC
1156 [4]; and, the Simple Network Management Protocol, RFC 1157 [5],
which defines the protocol used to manage these objects.  Consistent with
the IAB directive to produce simple, workable systems in the short-term,
the list of managed objects defined in the Internet-standard MIB was
derived by taking only those elements which are considered essential.
However, the SMI defined three extensibility mechanisms:  one, the
addition of new standard objects through the definitions of new versions
of the MIB; two, the addition of widely-available but non-standard
objects through the experimental subtree; and three, the addition of
private objects through the enterprises subtree.  Such additional objects
can not only be used for vendor-specific elements, but also for
experimentation as required to further the knowledge of which other
objects are essential.

This memo defines extensions to the MIB using the second method.  It
contains definitions of managed objects used for experimentation.  After
experimentation, if sufficient consensus is reached in the Internet
community, then a subsequent revision of this memo may be placed in the
Internet-standard MIB.


2  Objects

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) [7] defined in the
SMI. In particular, each object has a name, a syntax, and an encoding.
The name is an object identifier, an administratively assigned name,
which specifies an object type.  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
OBJECT DESCRIPTOR, to also refer to the object type.

The syntax of an object type defines the abstract data structure
corresponding to that object type.  The ASN.1 language is used for this
purpose.  However, the SMI [3] purposely restricts the ASN.1 constructs

R. A. Woodburn, Editor                                           [Page 3]


Internet Draft                    IDPR MIB                   October 1993


which may be used.  These restrictions are explicitly made for
simplicity.

The encoding of an object type is simply how that object type is
represented using the object type's syntax.  Implicitly tied to the
notion of an object type's syntax and encoding is how the object type is
represented when being transmitted on the network.

The SMI specifies the use of the basic encoding rules of ASN.1 [8],
subject to the additional requirements imposed by the SNMP.


2.1  Format of Definitions

Section 6 contains the specification of all object types contained in
this MIB module.  The object types are defined using the conventions
defined in the SMI, as amended by the extensions specified in [9].


3  Overview

The Inter-Domain Policy Routing Protocol (IDPR) is a routing protocol for
use between Administrative Domains.  The objective of IDPR is to
construct routes between source and destination administrative domains
that provide user traffic with the service requested within the
constraints stipulated by the domains transited.

With IDPR, we introduce a new network-layer Internet protocol based on
source-specified routing between administrative domains and a new
Internet addressing structure based on an administrative domain
hierarchy.  However, for IDPR version 1, we recommend implementing a
proper subset of the complete architecture proposed in [11].  The
recommended subset provides the majority of the features of IDPR and
comprises the virtual gateway protocol, the domain status distribution
protocol, the route synthesis procedure, the path setup protocol, and the
message forwarding procedure.


3.1  Domain Structure

The IDPR architecture has been designed to accommodate an Internet with
tens of thousands of administrative domains collectively containing
hundreds of thousands of local networks.  Inter-domain policy routes are
constructed using information about the policy attributes of, and the
connectivity between, administrative domains.  The intra-domain details,
gateways and networks traversed, of an inter-domain policy route are the
responsibility of intra-domain routing and are thus outside the scope of
inter-domain routing.

An Administrative Domain (AD) is a collection of contiguous networks
managed by a single administrative authority that places policy
restrictions on transit traffic, defines policy requirements for
locally-generated traffic, and selects the intra-domain addressing


R. A. Woodburn, Editor                                           [Page 4]


Internet Draft                    IDPR MIB                   October 1993


schemes and routing procedures.  Each administrative domain has a unique
identity within the Internet.

Virtual Gateways (VGs) are the only IDPR-recognized connecting points
between adjacent administrative domains.  Each virtual gateway is a
collection of directly-connected policy gateways in two adjacent domains,
whose existence has been sanctioned by the authorities in both domains.
The domain authorities may agree to establish more than one virtual
gateway between the two domains.  For each such virtual gateway, the two
authorities together assign a virtual gateway identifier, unique within
the set of virtual gateways connecting the two domains.  To produce a
virtual gateway identifier unique within its domain, the domain authority
concatenates the mutually assigned identifier together with the adjacent
domain's identifier.

Policy Gateways (PGs) are the physical gateways within a virtual gateway.
Each policy gateway enforces policy restrictions on transit traffic as
stipulated by the domain's administrative authority.  A single policy
gateway may belong to multiple virtual gateways.  Within a domain, two
policy gateways are neighbors if they are in different virtual gateways.
Within a virtual gateway, two policy gateways are peers if they are in
the same domain and are adjacent if they are in different domains.
Adjacent policy gateways are directly connected if they are the only
Internet-addressable entities attached to the connecting medium.  Note
that this definition implies that not only point-to-point links but also
networks may serve as direct connections between adjacent policy
gateways.  The authority for a given domain assigns to each of its policy
gateways an identifier, unique within that domain.


3.2  IDPR Functions

Inter-domain policy routing comprises the following functions:


  1. Collecting and distributing connectivity and policy information
     pertaining to transit domains.

  2. Synthesizing and selecting policy routes based on the connectivity
     and policy information associated with the transit domains and on
     the service requirements associated with the source.

  3. Setting up paths across the Internet, using the policy routes
     synthesized.

  4. Forwarding messages across and between administrative domains along
     the established paths.

  5. Maintaining databases of transit domain connectivity and policy,
     inter-domain policy routes, configured global information such as
     network-address/domain-identifier mappings, and configured local
     information such as the policy gateways within an administrative
     domain.


R. A. Woodburn, Editor                                           [Page 5]


Internet Draft                    IDPR MIB                   October 1993


As described in [11], a source domain controls synthesis and selection of
policy routes to destination domains, while intermediate domains on a
specific source-selected policy route determine whether or not the route
is consistent with their transit policies.  The route synthesis procedure
uses domain status information in the form of advertised transit policies
and adjacencies, to generate policy routes between source and destination
domains.  The source then selects policy routes from those provided by
route synthesis, according to its own service requirements.  Policy
routes require a path setup procedure during which policy gateways in
intermediate domains verify whether or not they will carry traffic
traveling along the path, and contingent upon route acceptance, form an
association between the path identifier and the previous and next policy
gateways on the path.  Following path setup, intermediate policy gateways
use the path identifier carried in data messages to forward data traffic
along the path.

Several different entities are responsible for performing the IDPR
functions.  Policy gateways collect and distribute status information
about their administrative domains, participate in path setup, and
forward data messages along established paths.  Path agents act on behalf
of hosts to select policy routes and to set up and manage paths.
Special-purpose servers maintain the routing databases which are
distributed with partial redundancy throughout the Internet.  Each
special-purpose server within an administrative domain has a unique
identifier, assigned by the domain authority.  Route servers are
responsible for both the domain status (connectivity and policy) database
and the route database.  Also, route servers synthesize policy routes
using domain status information and source traffic requirements.  Name
servers are responsible for the
domain-name/network-address/domain-identifier database.  Configuration
servers are responsible for databases of configured information that
apply to policy gateways, path agents, and route servers in the given
administrative domain and inform these entities of configuration changes.

Both route servers and name servers are organized hierarchically, where a
server's position in the hierarchy determines the extent of its database.
At the top are global servers that maintain information about all
Internet domains; at the bottom are local servers that maintain
information about a particular domain, its neighbors, and other
frequently visited domains, this last type of information usually
obtained from higher-level servers.  Hierarchical database organization
releases hosts and gateways from the burden of maintaining information
about large portions of the Internet, most of which they will never use.

In IDPR version 1, each policy gateway performs all IDPR functions,
including those of the path agent and the special-purpose servers.
Aggregating all routing functions into policy gateways simplifies
implementation; one need only install IDPR protocols in policy gateways.
Moreover, it simplifies communication between routing functions, as all
functions reside within each policy gateway.  We also note that IDPR
version 1 supports only a flat route server hierarchy; each policy
gateway contains a global route server.  We are presently investigating
approaches to making efficient use of hierarchically-organized routing
information.

R. A. Woodburn, Editor                                           [Page 6]


Internet Draft                    IDPR MIB                   October 1993


Given the size of the current Internet (on the order of 100
administrative domains) and the type of policies supported in IDPR
version 1 (access restrictions only), we believe that policy gateways
have adequate processing and memory resources to synthesize policy routes
and set up paths as well as to forward messages and participate in
intra-domain routing.  Meanwhile, we are developing autonomous route
servers and configuration servers, separate from policy gateways, so that
IDPR can accommodate larger numbers of administrative domains and
policies in the future.


3.3  IDPR MIB

These objects are used to control and manage an IDPR [11] implementation.

This MIB is broken into 10 sections.  The first section describes system
variables.  The remaining sections describe tables and individual IDPR
sub-protocols.

                          that are advertised and used for route computation
                          are marked as active.  Transit policies received
                          from remote domains are always marked as being in
                          the active state.

                          Note that a local domain's transit policies may
                          be in the active or inactive state.  Inactive
                          transit policies are not including in RID
                          configuration updates and are not used by route
                          computation.

                          For implementations that support table write
                          operations, writing the value inactive(2) to a
                          defined transit policy puts the policy into a
                          state where it is no longer advertised.

                          Depending on implementation, changing the status
                          to inactive(2) may not necessarily remove the
