To mitigate the unreliable properties of the underlying transport protocols used to transmit the cover-medium, the message header contains a sequence number. This sequence number coupled with the message caching system allows the recipient to both identify when an expected message is missing as well as request a resend of a particular message via a control message. This property also provides the added benefit of detecting erroneously or maliciously replayed messages.
When considering potential solutions for this problem, various types of Forward Error Correction (FEC) were considered. Due to the limited space available for message data as a result of the size of cover-medium available, the additional space required for redundant data by most algorithms considered deemed them to be unfit for purpose within this research effort's context.
