Networking Primer – Part 8: Summary

Holy cow, when starting to write this series I in no way expected it to turn into a 12 part, 3 month process.  I have covered so much, but there is so much more that could have been covered.  It’s been a challenge to keep pulling back and remembering that this is just a primer. To recap what we’ve covered by post:

Part Description
Part 1: Introduction Introduction to series content and objectives.
Part 2: Defining Networking with OSI and TCP/IP Suite Defining networking background, terminology and models.
Part 3: Application, Presentation and Session Layers Describes the tope 3 layers of the OSI model.
Part 4: Transport Layer, TCP and UDP A dip into the world of connection-orientated vs connectionless protocols.
Part 5.1: Network Layer – IP Addressing IP Addresses, what they are and how they are used.
Part 5.2: Network Layer – DNS and DHCP Converting IP addresses to names we can read and handing them out on a network.
Part 5.3: Network Layer – IP Routing Getting IP packets from one node to another.
Part 6.1: Data Link Layer, Ethernet and MAC Ethernet Frames for shifting local traffic.
Part 6.2: Media Access Control – CSMA/CD, CSMA/CA Getting access to the wire, fibre or air.
Part 6.3: Layer 2 Switching – Loops, Spanning Tree and Topologies Fitting LAN switches together,
Part 6.4: VLANs and other ANs (Area Networks) Security and Isolation with VLANs
Part 7: Physical Layer, Electrons, Photons and All Things Quantum Physical media and nerdiness.
Part 8: Summary Summary.

I’ve really enjoyed refreshing all my own knowledge on these basic concepts and hope you have too. Future series are to be more specifically focussed on network virtualisation and other areas of the data centre.
