Introduction

The AT-8116 is a high-performance 10/100Mbps switch representing

the next generation in switching technology. The AT-8116 employs

highly-integrated ASIC technology and a Gigabit/sec backplane to

significantly boost network performance. Its high density and

performance combine with exceptional functionality, such as RMON

support, VLAN capabilities and Full Duplex switching, to achieve

optimal network switching without expensive changes to the desktop

PC or cabling system. The AT-8116 exemplifies the design flexibility

which enables deployment as both a departmental and enterprise

switch, while enhancing network connectivity.

Description

The AT-8116 high-density switch features 16 dual-speed 10/100 UTP

ports with auto-sensing. Highly-integrated ASIC technology enables a

maximum throughput of over 2,000,000pps and 1.6 Gbps.

The switch boasts extensive management capabilities, such as the

ability to access the learning table and per/port counter statistics, and

to set configurations. Built-in RMON support for Groups 1, 2, 3, and 9

allows in-depth analysis of traffic flow, while implementation of the

Spanning Tree Algorithm prevents broadcast loops and provides fail-

safe network redundancy.

Introduction

Theory of Operation

Ethernet segment switches divide a large local network into smaller

segments, insulating each from the other’s local traffic and increasing

aggregate bandwidth, while still retaining full connectivity. The AT-

8116 is designed to be self-configuring and extremely fast, making

installation simple and providing an increase in available bandwidth.

The switch learns on which port stations are located by remembering

the source address of every packet received on every port. When

packets are received for stations that the switch has learned, they will

be forwarded to only the port on which the station is located. This is in

contrast to a hub, which sends every packet to every port.

If the switch receives a packet addressed to a station which the switch

has not learned, the packet is sent to every port, except the port on

which it was received, just as a hub would. This insures that full

connectivityismaintained.ThehighportdensityoftheAT-8116allows

for dedicated high-performance workstation links.
