The LANNET
LANswitch Plus LSA+
facilitates
communication
between ATM and
LANswitch Plus
users, greatly
reducing the expense
and complexity of
migrating to ATM.
n today’s highly competitive business
environment, corporate networks are
experiencing serious bandwidth
limitations due to the growing use of
increasingly powerful applications, expanding
number of users, and emerging requirements
for data, voice, and video support. Because
of these factors, networking–both as an
industry and a technology–is in the process
of an evolution to high-speed switching and
ATM. However, the process of integrating
existing enterprise networks into an ATM
environment cannot be achieved overnight.
Until then, organizations need a way to meet
the increasing demand for network services
today, and prepare the foundation for a
smooth migration to the ATM networks of
tomorrow, while leveraging their current
network investment.

The LANswitch Plus LSA+ Switch links
LANswitch Plus users and services with an
ATM network. It provides a high-speed
backbone connection between the
LANswitch Plus hub and an ATM switch,
or between LANswitch Plus hubs. ATM
Forum compliant LAN Emulation provides
connectivity beyond the workgroup, while
UNI (User-Network Interface) 3.0 signaling
ensures interoperability with other ATM-
compliant network devices. The LSA+
occupies 2 slots in the hub.

LANNET supplies an integrated family of
products that offer end-to-end ATM
connectivity. At the network center,
LANNET’s Collage 740 ATM Backbone
Switch delivers a high-performance solution
for today’s demanding backbone
requirements. For LAN-to-ATM
connectivity, the Collage family of access
switches and the LANswitch Plus LSA+
provide LAN-to-ATM internetworking and
LAN-to-LAN connectivity over ATM.
Workgroup switches support ATM or switched
Ethernet desktop connections to an ATM
backbone. At the desktop, LANNET’s
ATM adapter cards combine standards-
compliant interoperability with leading-edge
performance.

The LANNET LANswitch™ Plus LSA+ ATM Access Switch delivers a 155
Mbps, high-performance ATM Backbone solution for the LANswitch Plus family of switching
hubs, tightly integrating LAN and ATM networks to provide ATM services for LAN users.

2. LANNET gives network users the
flexibility to adopt ATM at their own pace.
The LSA+ integrates easily into existing
switched Ethernet, Fast Ethernet
and–uniquely–FDDI networks. This
integration allows organizations to
selectively enhance legacy network
performance to ATM levels in response to
increasing user needs.
E A S Y I N T E G R AT I O N W I T H AT M
Performance-boosting LANswitch Plus
modules, like the LSA+, plug directly into
the LANswitch Plus chassis, allowing
customers to deploy ATM technology where
it is needed most by simply inserting
modules into the hub.
The result is an economical, gradual
migration path that leverages your investment
in existing network infrastructure to the
fullest.
This built-in flexibility, together with
ATM value-added services, makes
LANNET LANswitch Plus the first hub in
the industry providing easy coexistence and
migration from shared LANs to switched
LANs to ATM.
AT M S E R V I C E S F O R L A N U S E R S
The LSA+ is the ideal way to combine the
performance, scalability and manageability
of LANswitch Plus networks, with the
benefits of an ATM backbone. ATM and
LANswitch Plus value-added services
operate end-to-end across LAN and ATM
networks, providing LAN users with ATM-
like services today.
LANswitch Plus congestion
management, like ATM flow control, puts
an end to lost packets, while LANswitch
packet priority will map directly to ATM
Quality of Service. These services guarantee
network performance and a rock-solid
foundation for delay-sensitive multi-media
applications.

The LANswitch Plus LSA+ supports a
collapsed backbone configuration to an
ATM backbone switch. The diagram
demonstrates the migration of a building
network to ATM. Each floor contains an
ATM access switch, and all floors are linked
through a central ATM backbone switch.
Workgroups span the enterprise—with
members in the same virtual LAN residing

LSA+ ATM
Access Switch
The LANswitch Plus LSA+
connects to an ATM backbone
switch,and can also form an
Inter-Switch Link to another
LSA+, or to a Collage 530
Ethernet to ATM Access Switch.
3. Direct ATM connection between LSA+
modules to form an Inter-Switch Link (ISL)
allows the design of cost-effective ATM
backbones.
An ISL connection between LSA+
modules allows a collapsed backbone to be
built using multiple LSA+ modules in a
LANswitch Plus hub. An LSA+ based
connection can then be made from the
LANswitch Plus hub to a backbone switch at
the center of the enterprise network.
The LSA+ can also be directly
connected to the Collage 530 Ethernet to
ATM Access Switch, allowing for a gradual
implementation of ATM.
By seamlessly integrating LANswitch
Plus and ATM technologies, the LSA+
ensures that clients and servers across the
campus network receive the bandwidth they
require, without the need for changes to
existing network installations.

With the LSA+, network managers can
define Virtual LANs that span the campus
network. Virtual LANs allow users in shared
and switched LANs to participate in the
same logical workgroup as ATM users and
resources. The LSA+ can transfer up to 256
Virtual LANs across the backbone and
creates a LAN Emulation Client for every
emulated LAN. LANNET’s Montage™
Network Management System makes
adding, changing and deleting Virtual LANs
as easy as point-and-click.

To keep a switched network running
smoothly, network managers must be able
to effectively monitor and troubleshoot the
switch. The LSA+ is fully monitored and
managed by SMON™, LANNET’s RMON
switch monitoring application which works
in conjunction with Montage, LANNET’s
comprehensive SNMP-based Network
Management System.
SMON provides full monitoring and
reporting of ATM traffic statistics received
and transmitted by the LSA+. SMON
passively monitors all traffic traversing the
multi-Giga Cellenium switching backplane,
giving network managers a top-down
perspective of activity in the switched
network.
Top-down switch management employs
a multitier methodology, beginning with a
global view of switch traffic and progressing
to specific views of individual switch ports–
such as the LSA+ switch port, and their
hosts. Using the global view, network
managers can quickly pinpoint areas of
interest in the switch, and then zoom in on
specific hosts or individual sessions in order
to analyze them in more detail.
Montage and SMON are fully integrated
with such popular management platforms as
HP OpenView/UNIX, HP OpenView/
Windows, and IBM NetView.

The LANswitch Plus LSA+ includes all the
functionality necessary to provide
transparent internetworking. ATM Forum-
compliant LAN Emulation built into every
LANswitch Plus LSA+ assures seamless
connectivity across the entire network. LAN
Emulation transparently connects LANs to
ATM by allowing existing network protocols
(such as IP, IPX, Appletalk, or DECnet) to
run unchanged over the ATM network.
