how to have no packet loss in a loosy network

[Shabahang]

Hello,
I am looking for a solution to have no packet loss in a loosy network.
some of the application are using UDP and some do not work properly with packet loss.
consider a central site and many remote clients(many WAN linkes on cisco).
thus I am thinking of a method like a tunel or something to retransmit all packets (including connection less proto).

Hello!

You can work at port level with the command flow control.
Disadvantage is often a loss of performance.
Other possibilities include reducing the port speed (a-100 instead auto) or inserting an older switch in the path.
