end of message (EoM)

End of Message

(EoM) is a control sequence of a data block with which the end of the message is marked. In ATM, the EoM signal is used to identify a service data unit (SDU) in a protocol data unit (PDU). If the segment type identification field of the Segmentation and Reassembly Sublayer

(SAR-PDU) is occupied in theATM adaptation layer of

AAL-3/4, then the end of the SAR-SDU is located in the corresponding SAR-PDU. In the case of e-mails, some communication partners write a short message in the subject field to shorten the transmission time and end this message with an EOM hint.
