Sensitivity to network traffic
Because MeetingPlace is connected to the LAN network, traffic on the local
LAN segment can affect MeetingPlace operations. In particular, a “broadcast
storm” (one or more systems on a network segment continuously sends
message packets to the local broadcast address) can bring a MeetingPlace
system down for the duration of the storm. Unless the system manager is
certain that broadcast storms will not occur, the MeetingPlace server should
be partially isolated from the rest of the network.

be partially isolated from the rest of the network.
To isolate the server, you can use an Ethernet router or switch. An Ethernet
switch is usually simpler and less expensive than a router. Many switches
include filtering mechanisms that control broadcasts. For example, the 3COM
LinkSwitch 1000 temporarily shuts down any port that generates an abnormal
number of broadcast messages. A MeetingPlace system connected directly to
a filtering switch is virtually immune to broadcast storms.
