Linux Networking Fundamentals


What to expect from this course

Throughout the course, we cover how an SRE can optimize the system to improve their web stack performance and troubleshoot if there is an issue in any of the layers of the networking stack. This course tries to dig through each layer of traditional TCP/IP stack and expects an SRE to have a picture beyond the bird’s eye view of the functioning of the Internet.

What is not covered under this course

This course spends time on the fundamentals. We are not covering concepts like HTTP/2.0, QUIC, TCP congestion control protocols, Anycast, BGP, CDN, Tunnels and Multicast. We expect that this course will provide the relevant basics to understand such concepts
