Concepts

• Bandwidth: Maximum rate of transfer over the internet
• Latency: Delay between two points in a network
  • delays include propagation delays for signals to travel across medium
  • also includes the processing delays by network devices
• Jitter: Variation in inter-packet delays
• Throughput: Rate of successful data transfer (measured in bits per sec)
  • bandwidth, latency and packet loss directly affects the throughput
• PacketPerSecond PPS: how many packets processed per seconds
• Maximum Transmission Unit MTU: Largest packet that can be sent over the network
