A customer need to knows the amount of lost packet ethernet during a switching time in its SDH ring.
The amount of lost packets is equal to:
Lost packets = Switching_time * BW / ( Packet_length)
it is necessary to make the conversion between the respective units.
Switching time [ms] -->Switching time [s] *10e-3
BW [Mbps] --> BW [bps] *10e6
Packet_length [bytes] --> Packet_length [bits] *8
The amount of lost packets in a switching time depended on the following parameters:
* Switching time
* Bandwidth = BW
* Packet Length (ETH)
Its necessary to keep in mind that processing time in the boards is not included, and the result is a estimate
