Detailed Description

The CommonHeaderTracer is born for tracing the common header of a Packet, which is present in all packets because it contains:

• the packet ID: it is used to distinguish one packet from another because it is unique
• the packet type: a string which explains the type of the packet (tcp, udp, cbr,...)
• the packet size: the size of the packet in bytes

The class extend Tracer, but it is compiled and linked in another library. Thus, users which want to change the output format of the trace file can write a new class and plug their library in the simulation (instead this). When the library are loaded a CommonHeaderTracer are instanced and is plugged to the PktTracer by invoking the Sap addTracer static method.

Member Function Documentation

void CommonHeaderTracer::format	(	Packet *	p,
		SAP *	sap
	)			[virtual]

This method writes a string in the trace file with the following format:

UID TYPE SIZE DIRECTION

where

• UID is the packet ID
• TYPE is the packet type
• SIZE is the size of the packet in bytes
• DIRECTION is the packet direction (u=to up module, d=to down module)

Parameters:

	p	pointer to the packet to be traced
	sap	pointer to the SAP instance which ask for the trace

Implements Tracer.
