Study Notes

Network Performance Criteria

Networks must satisfy specific performance criteria for effective operation.

Delay or Latency

Delay is a critical performance metric measured in two components:
- Transit Time: Duration for a message to travel from one device to another.
- Response Time: Time interval between making an inquiry and receiving a response.

Throughput

Throughput refers to the volume of data accurately delivered to the receiver within a specified timeframe.
Influacing factors include:
- Number of users on the network.
- Type of transmission medium used (e.g., wired, wireless).
- Capabilities of network hardware (e.g., routers, switches).
- Efficiency of network software (e.g., protocols, applications).
Good performance is characterized by high throughput and minimal delay.

Reliability

Reliability assesses network performance through:
- Frequency of Failure: How often the network experiences disruptions.
- Recovery Time: Duration needed for a link to return to normal operation after a failure.

Security

Security is vital in networks to safeguard data from:
- Unauthorized access by users.
- Data corruption or damage through various means.
