Protocol Formatter

Uses a header format object to create a header from a tagged stream packet.

This block takes in tagged stream and creates a header, generally for MAC-level processing. Each received tagged stream is assumed to be its own frame, so any fragmentation would be done upstream in or before the flowgraph.

The header that is created and transmitted from this block. The payload should then be sent as a parallel tagged stream to be muxed together later. The header is based entirely on the object, which is an object derived from the header_format_base class. All of these packet header format objects operate the same: they take in the payload data as well as possible extra metadata info about the PDU; the format object then returns the output and metadata info. This block then transmits the header vector and attaches and metadata as tags at the start of the header.

Parameters

Format Obj.

The format object to use when reading the header. This block uses a format object derived from a header_format_base class.

Length tat name

The tagged stream length key.

Example Flowgraph

Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI. Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately. The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.
