The Collage 530
provides the
connection between
Ethernet and ATM
network users.
LAN emulation makes
this ATM integration
seamless and simple.
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 voice, video, and multi-
media 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 maximizing
their current network investment.
The Madge Collage 530 Ethernet to ATM
Access Switch makes is easy to link switched
Ethernet LANs with ATM campus backbones.

The Collage 530 provides high-speed
switching between Ethernet workgroups
and gives them seamless access to a
155 Mbps ATM backbone. Up to sixteen
Ethernet LAN segments can be connected
to the Collage 530 switch. Each Ethernet
segment receives a dedicated 10 Mbps switch
connection plus transparent access to an
ATM backbone via efficient LAN emulation.
S TA N D A R D S – C O M P L I A N T AT M
Collage 530 signaling fully conforms to the
ATM Forum UNI (User-Network Interface)
3.0/3.1 standard, ensuring optimal backbone
utilization and interoperability with other
ATM-compliant network devices.
ATM sessions take place across the
network after the establishment of a virtual
circuit linking the end points. The
Collage 530 automatically establishes
a Switched Virtual Circuit (SVC) connection
as needed, and releases it when the
transmission is complete. The SVC can be
set up if the associated ATM switches are
capable of supporting SVCs.
The switch’s ATM interface supports
either SONET OC-3c or (in Europe)
SDH STM-1, the standards for 155 Mbps
over fiber.
The Collage 530 is compliant with the
IEEE 802.1d spanning tree protocol. Its
wire-speed filtering and forwarding ensures
compatibility with the existing Ethernet
infrastructure. The spanning tree protocol
increases the reliability of the network by
preventing illegal topologies that could
result in undesirable effects such as
broadcast storms.

Virtual LANs are a fundamental part of the
transition to ATM. Virtual networks allow
users in shared and switched LANs to
participate in the same logical workgroup as
ATM users and resources. They permit great
flexibility in configuring and re-configuring
the network, allowing organizations to
gradually upgrade clients and servers to
ATM, while maintaining workgroup
connectivity at all times. Each Ethernet port
on the switch can be assigned to a different
Virtual LAN.
Collage 530 special features including
Quality of Service (QoS), flow control,
and hierarchical Virtual LANs, operate
end-to-end across both networks, providing
a migration path from shared and switched
LANs to ATM.

The Collage 530 connects up to sixteen
Ethernet LAN segments to the ATM
backbone. It also delivers high-performance
switching between the LAN segments
attached to it. Local sessions between the
Ethernet segments are conducted across the
Collage 530’s high-speed switching fabric.
Non-local sessions are sent through the
ATM uplink to the ATM backbone, which
speedily delivers them to their destination.
The Collage 530, enables workgroups to
span the enterprise with members in the
same virtual LAN residing on either
Ethernet or ATM.
Another connection option links two
Collage 530 units back to back to create
a 155 Mbps ATM backbone. The data from
all sixteen Ethernet LANs is transferred
across this backbone simultaneously.

The Collage 530 switch includes all the
functionality required to provide transparent
internetworking between Ethernet and
ATM. Efficient LAN Emulation 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. The Collage 530
includes LECs for Ethernet ports–one LEC
for every emulated LAN.

Madge’s MultiMan suite of network
management applications provides an
integrated solution for managing all activity
on the network. This enables the manage-
ment, configuration, monitoring, and
analysis of both the ATM and Ethernet
LANs from a single management console.
MultiMan makes it easy to set up virtual
networks and to configure QoS parameters.
Performance is easily monitored and faults
diagnosed by viewing statistics graphs for
both ATM and Ethernet parameters.
These include Ethernet Port Counters,
SONET Counters, Bridge Port Counters
and ATM Interface Counters.
M O N I T O R I N G P O R T
The position of the Collage 530 as the
interface between the Ethernet and ATM
networks makes it an ideal point at which to
gather statistics and monitor network
performance.
The Collage 530 features include the
ability to configure one of the Ethernet
ports as a monitoring port, enabling traffic
on a selected Ethernet segment to be
viewed using a protocol analyzer. Traffic on
the monitored port is duplicated and sent to
the monitoring port.
MultiMan is fully integrated with such
popular management platforms as HP
OpenView/UNIX, HP OpenView/Windows,
and IBM NetView.

Upgrades to the Collage 530 software can be
easily downloaded from either MultiMan or
from a configuration terminal, ensuring full
compliance with evolving ATM standards.
