Dears,

This is Diaa from Huawei Telecommunications company and I have inquiry about the End-to-End Identifier Header in the diameter message as it's not stated clearly whether the End-to-End Identifier shall be unique on every request including the retransmitted requests or only unique for each new generated request and the retransmitted ones use the same End-to-End identifier, and below I put two snapshots; one from clause#3 (Diameter Header) [left picture] and one from clause#5.5.4 (Failover and Failback Procedures) [right picture] as both mentioned the End-to-End Identifier but in different ways, so please need to know what the standard means exactly in case of retransmission in terms of assigning the End-to-End Identifier
