Ethernet traffic estimation

MMS
GOOSE
SMV
Fast Ethernet = 100 Mbps
The bandwidth of the HSR ring is half of the Fast Ethernet, because each message is sent in
parallel into either direction.
For instance, estimated Ethernet traffic volume for a substation consisting of two sections
(20x GOOSE sender, 2x SMV sender) is: 20 x 0.01 + 20 x 0.1 + 2 x 5 = 12.2 Mbps
Knowledge of data flows and traffic patterns allows for detecting bottlenecks and planning
the network segmentation and segregation of traffic.
