Concept for segmenting an application buffer into data packets
An apparatus, a method, and a computer program for generating data packets according to a transport protocol from an application buffer comprising a plurality of data streams is provided. The apparatus comprises an input circuit configured to receive metadata comprising at least one of information about data packet types supported by the transport protocol, information about an offset and a length of the supported data packet types, and information about possible stream header start positions, possible payload start positions and possible offsets in the data streams. Further, the apparatus comprises a parsing circuit configured to identify offsets in an application buffer as possible segmentation points based on the metadata, to segment the application buffer at the possible segmentation points into segments for data packets, and to generate data packets according to the transport protocol based on the segments. Furthermore, an apparatus, a method and a computer program for processing the application buffer is provided.
