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
