aka Networking for Web developers

As Web developers, our job is obviously to build web applications. But how can we build applications that rely on networking if we don’t know how these networks and the big network that connects them all (this thing called the Internet) actually work ? 
In this tutorial, we walk through the basics of networking, before diving into all the essentials every Web developer should know, from TCP/UDP over IP addressing (IPv4/6), source/destination ports, sockets, DNS, switching, firewalling and even more advanced protocols such as OSPF, VRRP and BGP. 
Prepare for an eye-opener when you realize how much a typical app relies on all of these (and many more) working flawlessly… and how you can prepare your app for failure in the chain.

This is a 2-day training course (14h) which will cover the following subjects :

  • Networking fundamentals
  • Packets and their structure
  • Networking layers
  • Switching
  • IP addressing (IPv4 and IPv6), subnet masks, …
  • IP ranges, prefixes, …
  • Static Routing

  • TCP, handshaking
  • Optimizing TCP performance
  • UDP
  • Source and destination ports
  • VLANs
  • ICMP
  • DNS, delegation, reverse DNS, DNSSEC
  • Advanced routing : OSPF and BGP
  • Failover : VRRP, Heartbeat, VIPs, uCarp
