Communicating network flow data using a network protocol

A computer program product (CPP) comprising:

• a set of storage device(s);
• and
• computer code stored collectively in the set of storage device(s), with the computer code including data and instructions to cause a processor(s) set to perform at least the following operations:
• defining a new ethertype to be used in communicating PIDs (process identification codes), with the new ethertype being assigned a new ethertype code,
• determining a selected abstraction layer from a plurality of abstraction layers to be used in communicating PIDs, and
• making a plurality of network communications among and between computers of a networked computers system, with each communication, with the making of each given communication including:
• inserting the new ethertype code and a PID of a process causing the given communication to occur into a data structure, and
• communicating the data structure between computers of the networked computers system at the selected abstraction layer.
