Hello Kostas,

early packet discard is implemented in the output port processor of an ATM switch. Check out the following link for some in-depth info on EDP:

It's always outgoing. ATM switches to discard entire packets (early packet discard) or the remaining cells of a packet that has experienced loss (partial or tail packet discard), or to merge packets from different incoming connections onto thesame outgoing connection (virtual circuit [VC] merge).
