# 用語(terms)
|Trem|Description|
|:--|:--|
|Data ID |An identifier that uniquely identifies the message / data element / data.
|Source ID |An identifier that uniquely identifies the source of the message / data element / data (i.e., in case different sources produce the same message / data element / data – like different clients invoking the same method at a server).
|Repetition| The same message was received more than once.
|Loss| A message was not received.
|Delay| A message was received later than expected.
|Insertion| Unexpected information or an extra message was inserted.
|Masquerade| non-authentic information is accepted as authentic information by a receiver.
|Incorrect |addressing information is accepted from an incorrect sender or by an incorrect receiver.
|Corruption| A communication fault, which changes information.
|Asymmetric information| Receivers do receive different information from the same sender.
|Subset |Information from a sender received by only a subset of the receivers.
|Blocking |Blocking access to a communication channel.
|FTTI |Fault tolerant time interval, maximum time a fault can be active before a hazard occurs
