what is the internet traffic? Is the flow of data across the Internet. Because of the distributed nature of the Internet, there is no single point of measurement for total Internet traffic. Internet traffic data from public peering points can give an indication of Internet volume and growth, but these figures exclude traffic that remains within a single service provider's network as well as traffic that crosses private peering points

 Is the flow of data across the Internet.
 Because of the distributed nature of the Internet,
there is no single point of measurement for total
Internet traffic. Internet traffic data from public
peering points can give an indication of Internet
volume and growth, but these figures exclude
traffic that remains within a single service
provider's network as well as traffic that crosses
private peering points

6. Introduction to Internet
Traffic
 Accurate traffic identification and insightful
measurements, form the foundation of
network business intelligence and network
policy control. Without identifying and
measuring the traffic flowing on their
networks, CSPs (Communicating sequential
processes)are unable to craft new
subscriber services, optimize shared resource
utilization, and ensure correct billing and
charging.

7. Typical traffic classes
1) Sensitive traffic
Sensitive traffic is traffic the operator has an expectation
to deliver on time. This includes VoIP, online gaming,
video conferencing, and web browsing.
2) Best-effort traffic
Best effort traffic is all other kinds of non-deterimental
traffic. This is traffic that the ISP deems isn't sensitive to
Quality of Service metrics (jitter, packet loss, latency).
3) Undesired traffic
This category is generally limited to the delivery of spam
and traffic created by worms, botnets, and other
malicious attacks. In some networks, this definition can
include such traffic as non-local VoIP (for example,
Skype)

9.  The Internet is an un-natural system,
in widespread use. Its providers and
users need to understand it!
 ISPs need to manage traffic loads,
detect unusual behaviour
 Researchers need to observe how
traffic behaves, so as to understand
changes in traffic pattern

10. The Internet is always changing.
we need alots of data, to ensure
our measurement consistency.
we need to share our data, so
others can verify our work.
10

11.  There are many different measurement
techniques
 some of them are ‘direct,’ e.g: send a test
packet to measure transit time
 others are much less direct, e.g:
Packet dispersion to measure available
bandwidth
 Passive methods, e.g. observing links to
measure properties: (sizes, lifetimes) of traffic
flows

13. How we measure internet
traffic application
 Various software tools are available to
measure network traffic.
 Software like :
 Argus
 Cacti
 cFosSpeed
 FlowMon
 LiveAction
 NetBeez
 NetLimiter
 Wireshark
 NetFlow
13

14. The data collection and
analysis
 We use software wireshark to do it.
 Wireshark is a free and open-
source packet analyzer. It is used
for network troubleshooting,
analysis, software and
communications protocol
development, and education.
