Design Implementaion of Traffic measurement
agent and Collection server

• Advisor Prof. Won-ki HongDPNM
• Department CSE
• Student number 20001033
• Name Jaeyoung Kim

Simple Description

• Traffic measurement agent
• AGENT Executed on PC
• Packet capturing and analysis
• Gathering cumulative traffic amount based on
  process
• Send to server gathered information
• Collection server
• Receive data from agents and processing

Diagram

• Each agent does

• Measuring traffic amount
• Build process table
• 3. Furnish data to PC user
• 4. Send data to server

Research

• How can I capture a packet?
• Implement it by myself?
• Do not overestimate yourself.
• Use windows API offered by MS?
• I couldnt find.
• Use open source PCap library?
• Adequate solution!

6
Research

• Packet capturing
• UDP protocol
• Massive resource overhead prospected to know the
  starting point of UDP stream
• Discard UDP packet
• TCP protocol
• TCP SYN FIN packet means the starting ending
  point of TCP stream each
• Packets are ordered
• Negligible overhead to CPU!

7
Current

• Functioning of Agent
• Packet capturing
• Check
• The time of packet captured
• Packet length
• Delicate packet parsing is not completed yet

8
What to do

• Traffic measurement agent
• Packet header parsing
• Process table building
• Development of packet processing routine
• Graphical works
• Collection server
• Implementation!
