Formal title: Out of Sequence File Handling

Current Status

CPC Consultation
Committee Decision


BSC, Section P 2. 3. 5 and 3. 3. 5 relates to the ordering of Volume Notifications (ECVNs and MVRNs respectively), and requires only that it be established whether one Volume Notification is prior to another.
Therefore, in order to ensure that Volume Notifications were processed in the order required by the Notification Agent, ECVAA implemented File Sequence Numbering. This requires that file headers of Volume Notifications contain a File Sequence Number and on receipt of each Volume Notification from a Notification Agent, ECVAA checks the File Sequence Number to determine whether the Volume Notification is the next expected file (i. e. the File Sequence Number of the last received file incremented by 1) from that Notification Agent.
