Example for calculating the Latency
5.1 Problem Statement
Calculate the round-trip time (RTT) latency for a data packet traveling between a client in New York City and a server in London, UK, assuming a direct fiber-optic connection with a propagation speed of 200,000 km/s.
- Distance: Distance between NYC and London: 5570 km
- Propagation speed: 200,000 km/s
- Constraints: Assume no network congestion or processing delays.
- Desired Output: RTT latency in milliseconds.
5.2 Problem Statement
Calculate the average latency for a user clicking a button on a web application hosted on a server with a 5 ms processing time. Assume a network latency of 20 ms between the user’s device and the server.
- Network latency: 20 ms
- Server processing time: 5 ms
- Constraints: Assume no additional processing delays on the client-side.
- Desired Output: Average latency in milliseconds.
Latency and Throughput in System Design
Latency can be seen as the time it takes for data or a signal to travel from one point to another in a system. It encompasses various delays, such as processing time, transmission time, and response time. Latency is a very important topic for System Design. Performance optimization is a common topic in system design, Performance Optimization is a part of Latency. In this article, we will discuss what is latency, how latency works, and How to measure Latency, we will understand this with an example.
