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 failsafe 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 AT8116 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
connectivity is maintained. The high port density of the AT-8116 allows
for dedicated high-performance workstation links.
