Packet PSEtherAppMsg

File: src/PSetherApp/PSEtherApp.msg

The Publish-Subscribe Application Packet

Pub-sub packet sent by Publish and Subscribe Ethernet Applications. Contains the FID of the message, in order to be forwarded to the correct subscribers, the type of the packet (e.g. ), the length of the scope (according the the 8 byte PURSUIT_ID_LEN) and finally the whole Information Item ID (IIID). This IIID includes the scope and the ID of the Information Item sent, according to the C++ class, InformationItem. If the size of the PSEtherApp message is greater than ~1400, it will consist of several Ethernet frames. The last field of the message is optional and can be used for detection of palse positives. It is suggested that it is controlled by a global variable.
