Application and data protection tag

The system as recited in claim ii, wherein the ADPL tag is designated within the application payload at a start of the ADPL tag by a start of frame delimiter (SFD) and at an end of the ADPL tag by an end of frame delimiter (EFD), and wherein the ADPL tag is stored at a beginning of the application payload, at an end of the application payload, or between the beginning and the end of the application payload using a programmable offset.

A computer program product, comprising a computer readable storage medium having program instructions stored thereon, the program instructions being executable by a processing circuit to cause the processing circuit to:

• generate a multi-context application and data protection layer (ADPL) tag unique to a pair of data socket descriptors on which data is to be received and/or transmitted by a first application instance operating on a first host and a second application instance operating on a second host;
• and
• embed the ADPL tag as part of an application payload in response to the first application stan e calling an application programming interface (API) configured to transmit the application payload out from the first host via a sender data socket descriptor.
