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 describes managed objects used for managing the
Rapidly Deployable Radio Network (RDRN) Network Control Protocol
(NCP).
The Network Management Framework
The Internet-standard Network Management Framework consists of three
components. They are:
Bush & Jagannath Expires in June 1997 [Page 1]
Internet-Draft Mobile Wireless GPS-Based Configuration 13 January 1997
STD 16/RFC 1155 which defines the SMI, the mechanisms used for
describing and naming objects for the purpose of management. STD
16/RFC 1212 defines a more concise description mechanism, which is
wholly consistent with the SMI.
STD 17/RFC 1213 which defines MIB-II, the core set of managed
objects for the Internet suite of protocols.
STD 15/RFC 1157 which defines the SNMP, the protocol used for net-
work access to managed objects.
The Framework permits new objects to be defined for the purpose of
experimentation and evaluation.
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) [3]
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.
Format of Definitions
Section 5 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 [5,6].
Overview
Network Control Protocol Terminology
This section defines some of the terminology used in the Description
of the NCP operation.

Internet-Draft Mobile Wireless GPS-Based Configuration 13 January 1997
o "AX.25"
Asynchronous X.25 Protocol (See [1]).
o "Callsign"
The packet radio callsign is assigned by the FCC and
identifies the packet radio operator.
o "Edge Switch" (ES)
A node which either resides within the wireless
network or at the edge of the fixed and
wireless network and which serves as a base station.
o "Global Positioning System" (GPS)
Satellite system which provides location and time.
o "Remote Node" (RN)
A host with the ability to connect via a beamforming
antenna to an edge switch (ES).
Rapidly Deployable Radio Network Control Protocol
The Rapidly Deployable Radio Network (RDRN) [8] and [9] consists of
links formed by beamforming antennas. While beamforming allows
improved spectrum usage through spatial reuse, it poses a challenge
to configure. Each mobile node and base station contains a GPS
receiver and is aware of its current location. This information is
shared among nodes and an optimal topology for beamformed links is
determined. The protocol which carries this information is known as
the network control protocol (NCP) [11]. The NCP is carried over an
omni-directional packet radio overlay network. See reference [12] for
information about Virtual Network Configuration (VNC) and NCP.
MIB Groups
The definition of managed objects for the NCP is divided into eleven
groups:
Bush & Jagannath Expires in June 1997 [Page 3]
Internet-Draft Mobile Wireless GPS-Based Configuration 13 January 1997
(1) Initialization Group
(2) Configuration Group
(3) NCP AX.25 Connection Group
(4) Edge Switch Group
(5) Remote Node Group
(6) GPS Specific Stats Group
(7) Packet Radio Specific Stats Group
(8) NCP Layer Specific Stats Group
(9) ATM Stacks Group
(10) Beam Coverage Group
(11) NCP Status Group
The initialization group objects pertain to the initial startup of
the NCP enhanced mobile node. The configuration group objects control
timing, encryption, and other configuration information for the NCP.
The NCP AX.25 [10] group objects maintains a mapping of packet radio
AX.25 streams to callsigns. This is useful for determining which
AX.25 packet radio connections are currently established. The Edge
Switch (ES) and Remote Node (RN) group objects manage information
need by the beamforming algorithm to properly steer beams. The GPS,
Packet Radio, and NCP Layer group objects manage GPS, NCP Packet
Radio, and NCP information.
The ATM Layer configuration objects are described in more detail in
the next section.
The Beam Coverage group objects provide access to information about
the currently active beams. Finally, the NCP Status group objects
pertain to timing information of interest to NCP. Virtual Network
Configuration (VNC) [11] is managed by a separate MIB.
ATM Configuration MIB Objects
The ATM Stacks group objects manage the currently active ATM stacks
on an ES or RN. As the orderwire network determines the topology of
all nodes in the wireless segment (e.g., RNs, ESs) in our architec-
ture, and establishes link connectivity among adjacent nodes, setup
is still required of the actual ATM circuits on which wireless ATM
are carried on the user data overlay network. This is accomplished by
providing standard ATM signaling capabilities to RNs and ESs and
using Classical IP over ATM to associate ATM VCs to IP addresses. The
Classical IP over ATM implementation provided works for PVCs and SVCs
(using ATMARP).
Since an ES may connect to multiple RNs (wireless connections) or ATM
Bush & Jagannath Expires in June 1997 [Page 4]
Internet-Draft Mobile Wireless GPS-Based Configuration 13 January 1997
switches (wired connections), it can be thought of as a software-
based ATM switch. In this sense, an ES features ATM PNNI signaling
while an RN features ATM UNI signaling. By default, an RN creates one
wireless-ATM protocol stack and establishes an ATM VC signaling chan-
nel on such a stack; however, the stack is initially in an inactive
state (i.e., non-operational mode) since there is no link connectiv-
ity to another node established yet. Likewise, an ES creates a pre-
defined number of wireless-ATM protocol stacks -- acting like ports
in an ATM switch -- and establishes ATM VC signaling channels on all
configured stacks which are also initialized as inactive. Wireless-
ATM protocol stacks are controlled by a daemon, called the adaptation
manager, which acts on behalf of the orderwire network. The adapta-
tion manager daemon not only controls the stacks by setting their
state to either active or inactive (default), but also may modify
configuration parameters of the stacks to provide dynamic adaptation
to link conditions.
Two possible scenarios illustrate the interactions between the order-
wire network and the wireless-ATM network. In the first scenario the
orderwire detects link connectivity between an adjacent pair of nodes
(e.g., RN-ES or ES-ES). In this case, the orderwire network requests
an inactive stack from the adaptation manager daemon at each end and
associates them with a designated address. Upon establishment of link
connectivity, a requested wireless stack has its state set to active
and is ready to operate. Note that since the signaling channels are
preconfigured on the stacks in question, users on the wireless estab-
lish end-to-end connections exactly as if they were connected in a
wired ATM network.
The other scenario occurs when the orderwire network detects a broken
connection, at the link level, between two connected nodes. This case
is typical of an RN moving away from the connectivity range of an ES.
The orderwire network thus contacts the adaptation manager daemon at
each end to set the wireless stacks in question to inactive. Since a
wireless stack is never destroyed, it can be reused in a future
request from the orderwire to establish connectivity to another pair
of nodes.

"Describes the NCP state of operation:
down - node administratively idle.
configuring - es-es topology configuration or
initial startup.
associating - handoff in process.
active - other normal operation.
delay - node is in a delay mode, e.g.
remote node waiting between
updates."

packets. A transition setting from idle to active
causes the NCP process to re-initialize as though
just started."

Security Considerations
Clearly, the DES encryption key should not be accessible in the MIB,
however, this remains in the MIB for debugging and testing purposes.
Also, critical timing parameters are set-able from this MIB. Again
this is useful for experimental purposes, but may not be desired for
commercial use.
