Note: Set your switch to auto-negotiate. If your switch does
not support auto-negotiation, it is recommended that it be set
to 100 BaseT Full Duplex

You will need to install additional MeetingTime software on Windows-based
desktops that are intended for use by MeetingPlace end users, contacts, or
attendants.

Sensitivity to Network Traffic
As a consequence of being connected to the LAN network, MeetingPlace
operations can be affected by traffic on the local LAN segment. In particular,
the phenomenon called a “broadcast storm” can bring a MeetingPlace system
down for the duration of the storm. A broadcast storm occurs when one or
more systems on a network segment continuously send message packets to
the local broadcast address. The system manager should consider partially
isolating the MeetingPlace server from the rest of the network unless there is
a high confidence that broadcast storms would not occur.

An Ethernet router or switch can be used to provide isolation. An Ethernet
switch is usually much simpler and less expensive than a router. Many
switches include filtering mechanisms for the purpose of controlling
broadcasts. For example, the 3COM LinkSwitch 1000 will temporarily shut
down any port that generates an abnormal number of broadcast messages. A
MeetingPlace system connected directly to a filtering switch should be
immune to broadcast storms.

A MeetingPlace server placed on its own router segment should also be
immune to broadcast storms. A moderately expensive solution is to place a
two-Ethernet-port router in between the MeetingPlace system and the main
network. An example of such a device is the Cisco 2514.
