Analyzing Traffic (Use of Traffic Data)
Traffic Control and Management
• Types of traffic control
• Macroscopic
• Route topology
• Use of BGP
• Filters
• Microscopic
• Control at point of forwarding
• Examine payload
• Firewall
• Intrusion Detection System
Example : Web Servers Traffic Mgmt.
• Huge number of requests
• Server Farm
• Load Balancer
• Internet Uses Global Load Balancing
QoS and Pricing Issues
• Internet Data
• Text
• Audio
• Video
• Impact on SLA
• Traffic Variations
• Flow and Sessions
• Streaming and Elastic Flow
• Variable Rate of Traffic Streams
Conclusion
Even if complex nature of Internet data, using efficient measuring method we can gather required data to analyze the traffic. Implementing appropriate control mechanisms we can avoid traffic in Internet. Mechanisms depend upon nature of traffic.
