Detailed Description

The IpHeaderTracer is born for tracing the IP header of a Packet, which contains:

• the IP address of the destination and the source of the packet
• the port of the destination and the source of the packet
• the remain TTL
• the next hop

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 IpHeaderTracer are instanced and is plugged to the PktTracer by invoking the Sap addTracer static method.

Member Function Documentation

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

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

--IP-- SRC:SPORT DST:DPORT TTL NH

where

• SRC is IP address of the source node
• SPORT is the port of the source node (TCP or UDP)
• DST is the IP address of the destination node
• DPORT is the port of the destination node (TCP or UDP)
• TTL is the remain Time To Live
• NH is the IP address of the next hop node

Parameters:

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

Implements Tracer.
