NauticaRS Protocol Implementation
NauticaRS provides a comprehensive set
of standards-based IP, IPX, Frame Relay,
and PPP features and services.
The Marlin Network Access Servers’
IPX implementation provides increased
network security and reduced overhead
traffic through its IPX RIP and SAP
Direction Control feature.
IP NauticaRS provides all standard IP
functions and supports major Internet
Engineering Task Force (IETF) Request for
Comments (RFCs) for protocols including
IP, TCP, RIP, ARP, ICMP, UDP, DHCP,
BootP Relay, Dynamic RIP routing, and
static routes. This range of support
ensures users highly reliable, standardsbased connectivity and interoperability.
Marlin Network Access Servers’ IP implementation provides increased network
security and reduced overhead traffic
through its IP RIP Direction Control
feature. This feature controls the flow
of broadcast traffic over the network.
Broadcast traffic generated by IP RIP can
be configured as send only, receive only,
both, or neither on a per-path basis.
NauticaRS also allows static routes to be
“blacklisted” to allow DADS to be supported for dynamic and static routing
table entries. This provides greater
resilience in a meshed ISDN environment.
IPX The Marlin Network Access Servers’
IPX implementation supports LSAP/LLC2,
SNAP, and Novell Proprietary protocol.
RIP routing is also supported to ensure
that the best path to a destination is used.
Additionally, the Marlin’s IPX Default
Route feature enables packets to be sent to
an address that is not known in the Marlin
Network Access Servers’ routing table.
Bay Networks also reduces traffic on
the network through its SAP and SPX
spoofing support.
Frame Relay Bay Networks NauticaRS
Frame Relay support allows remote access
to corporate networks or the Internet over
public or private Frame Relay networks.
Marlin Network Access Servers can support up to 64 PVCs over a Frame Relay
network. This Frame Relay implementation supports RFC1490 encapsulation,
ensuring multivendor interoperability
over Frame Relay for IP/IPX routing and
transparent bridging.
PPP and Multilink PPP Industry-standard
Point-to-Point Protocol (PPP) and RFC
1990 — Multilink PPP (MP) — are supported for multivendor interoperability
over ISDN and leased lines. PPP and MP
are enhanced by the Marlin Network
Access Servers’ support of Point-to-Point
Tunneling Protocol (PPTP), Bridge
Control Protocol (BCP), and Bandwidth
Allocation Control Protocol (BACP),
which extend connectivity, ensure adequate bandwidth, and provide security.
PPTP allows PC users to extend the PPP
connection over a composite path of LAN
and ISDN links. An extension of PPP,
PPTP supports virtual private networks
(VPNs) and provides branch office and
remote/mobile users low-cost access to
corporate network resources via a secure
Internet connection. This eliminates long
distance charges as well as management
and security issues associated with maintaining private networks. BCP allows
non-routed protocols such as AppleTalk
to be bridged over a PPP link to any
other router or bridge supporting the
PPP/BCP standard.
Bandwidth Allocation Control Protocol
(BACP) manages the bandwidth available
during Multilink calls. Via BACP, a platform not initiating the call has the ability
to negotiate bandwidth with the platform
initiating the call. The negotiation can be
based on available resources or through
the dynamic monitoring of the actual traffic across the link. This solves the problem
of insufficient bandwidth, which often
occurs when ISDN links are repeatedly
initialized and brought down (thrashing),
by ensuring that both ends have adequate
bandwidth for operation.
Data Compression
NauticaRS software enables the Marlin
Network Access Servers to increase the
amount of data that can be carried across
an ISDN or leased line. Bay Networks
routers provide the most comprehensive
data compression support in the industry.
This support ensures compression interoperability with a wide array of remote
environments, ranging from third-party
routers to Microsoft Windows workstations. Marlins use Lempel-Ziv-based
STAC data compression techniques and
support RFC 1962 — Compression
Control Protocol (CCP) — along with
Bay Networks WAN Compression
Protocol (WCP). Microsoft Point-toPoint Compression (MPPC) is supported
to optimize throughput in customerspecific applications. Bay Networks
data compression support improves
performance and throughput without
compromising compatibility by using
standards-based techniques.
Dial Services
Remote office connectivity and availability
is ensured via NauticaRS dial-up services
support, which includes Dial-on-Demand,
Bandwidth-on-Demand, and Dial Backup
for the Marlin Network Access Servers.
Data Sheet Marlin Network Access Servers

Marlins also support ISDN Terminal
Adapters. This enables Marlin Network
Access Servers to accept and make calls to
standalone ISDN access routers that use
PPP and PC/notebooks using integral or
standalone ISDN Terminal Adapters supporting PPP or V.120.
Dial-On-Demand Marlin Network Access
Servers take full advantage of the speed
and bandwidth of ISDN lines while maintaining control of ISDN call costs. Its
industry-leading features for minimizing
line usage help network managers realize
maximum cost savings with ISDN Dialon-Demand connections for sites with
intermittent data transfers. The Marlin
Network Access Server brings up a link
automatically when there is data to transfer
and closes down the link once traffic has
stopped for a specified amount of time.
Bandwidth-on-Demand Marlin Network
Access Servers provide Bandwidth-onDemand via Multilink PPP to provide
additional bandwidth across an ISDN link
during peak usage periods. BACP is used
as the mechanism to add or delete links.
Once line usage reaches a predefined level,
the Marlin Network Access Server will
open a second B-channel and load balance
traffic across both channels. When line
usage drops below the predefined level, the
Marlin Network Access Server closes down
one B-channel and returns to the original
bandwidth. For Marlin Network Access
Servers with ISDN interfaces, Bandwidthon-Demand can be used to increase the
synchronous port’s bandwidth by using
ISDN channels during peak traffic periods. Bandwidth-on-Demand can also be
used to add bandwidth to ISDN B-channels that are already being used.

Data Sheet Marlin Network Access Servers
Dial Backup The Marlin Network Access
Servers can use ISDN to back up a dedicated link. In the event that the dedicated
link goes down, the Marlin Network
Access Servers activate the ISDN connection in its place. When the dedicated link
is restored, the Marlin Network Access
Servers terminate the backup connection
and resume use of the dedicated link.
SeaView Bay Networks SeaView configu-
rator is a Windows 95 Wizard application
that provides an easy-to-use and consistent graphical user interface (GUI) to set
up or make changes to Marlin Network
Access Servers. Initial configuration of the
Marlin is done using the Bay Networks
SeaView Windows 95 Wizard set up
facility. This allows users to configure
the router quickly, easily, and accurately.
Configuration and Management
Through NauticaRS, Bay Networks Marlin
Network Access Servers provide many
features that simplify configuration and
provide SNMP-based network management capabilities. Marlin Network Access
Servers can be configured and managed
from any local or remote ANSI-standard
terminal or from a PC on the network
using Telnet. SNMP-based management
systems including HP OpenView, Tivoli
NetView for AIX, and Sun Microsystems
Solstice Domain Manager can be used to
manage a Marlin Network Access Server.
Bay Command Console (BCC) This terminal-based (TTY-compatible) tool enables
local or remote platform installation and
maintenance. It is accessed through a
directly attached terminal or PC running
terminal emulation software or a Telnet
session. With support for BCC, NauticaRS
provides command line syntax, which is
consistent with other Bay Networks platforms that support BCC. This is ideal for
situations where the management of the
remote routers is being performed from a
central site.
Security
Bay Networks NauticaRS enables authorized remote users to reach all the
information they need while potential
intruders are prohibited by its multilevel
security features.
Marlin Network Access Servers support
the Remote Authentication Dial-In User
Service (RADIUS), a client/server-based
security protocol. This enables the Marlin
to provide a comprehensive set of security
features and meet varied network requirements. Residing on a Windows 95 or
Windows NT platform, and when used
with the Marlin, RADIUS provides
network-wide authentication and authorization to maintain security when remote
access is required. Several levels of comprehensive security features are provided
including Calling Line Identification (CLI)
feature, which provides verification that
incoming ISDN calls have authorization to
connect. For PPP connections, PAP and
CHAP are supported. Additionally, the
Marlin Network Access Servers’ RADIUS
implementation will operate with other
third-party RADIUS servers.
