Hi,

I have a question about the functionality of Alarm Reporting....

Assuming that there is a failure at a server layer somewhere across the
network....and the MEP of the server layer identifies it and needs to
ensure that Alarm Reporting is sent to all of the MEPs of the client
services that transmit over the failed server...but it may be that some
of the client services do not have MEPs....how does the node detecting
the server failure knows which client services have MEPs and an Alarm
Reporting message needs to be sent to their MEPs and which do not have
MEPs and an Alarm Reporting message must not be sent for these client
services....(as we would not like to flood the network with unnecessary
traffic)....

I hope someone can clarify it to me.

Best regards,

Nurit
