TCP? UDP? Que? - Fundamentals That Were Abstracted Away from Us

Explore the fundamentals of network communication protocols in this 45-minute conference talk from Devoxx. Dive deep into the world of sockets, covering TCP, UDP, and custom protocols. Understand the importance of knowing what goes on under the hood of abstractions in software development. Learn about the layers of communication, TCP full duplex, flow control, and congestion. Compare bandwidth vs latency and examine HTTP latency. Discover the benefits of TCP and UDP, and see code examples for implementation. Investigate network routing, broadcasting, and streaming. Use Wireshark to analyze network traffic. Gain insights into making informed decisions when working with single-page applications, web sockets, and other frameworks built on top of sockets.
