Wireshark is a network packet/protocol analyzer.
◦ A network packet analyzer will try to capture network packets
and display packet data details.
The basic tool for observing the messages exchanged
between executing protocol entities is called a packet
sniffer.

MRTG is a tool to monitors and measures the traffic
load on network links (web server, router).
MRTG generates HTML pages containing graphs
which provide a LIVE visual representation of the
traffic.
Typically collects data every five minutes.
Prepared by: Engr. Syed Abdul Basit
MRTG uses the Simple Network Management
Protocol (SNMP) to send requests.
MRTG consists of a Perl script which uses SNMP to
read the traffic counters of the routers.

PT 5.0 is now a network-capable (peer to peer) application, using the real network (TCP socket connections) to carry the
Packet Tracer virtual packets.
The PT application running on one computer can communicate with the PT application running on 1 or more
other computers.
This connectivity between multiple instances of PT supports teamwork, classroom games, collaboration, competition,
remote instructor-student interaction, and social networking.
