There will be a slowdown in posts for a few weeks whilst I prepare a new book for publication. I wrote a piece on Quality of Service (QoS) in packet networks in 2012. The piece was never published, and I have kept it all this time without really thinking about what to do with it. I thought about serializing it into a series of blogs, but I don’t think that would do it justice. As such, I have chosen to add two new chapters to bring it up to day, review it and publish it as a paperback and for kindle.
The piece looks at all aspect of Quality of Service in IP networks: looking at service classification, admission control, resource reservation, constraint routing and scheduling mechanisms. I also looked at layer 2 service Quality of Service based on Metro Ethernet Forum compliant services. I still need to adjust that part and add a section looking at QoS in SD-WAN environments.
What is different with my approach is applying historical context to each technology. Technologies come a go and some stick around. Each have their time but looking at when a technology was developed and why helps us to understand why there are so many approaches the QoS in packet networks today. I believe looking at technology in this way helps lead to deeper understanding.
Hopefully I will be finished by the end of March. I will let you all know when it is done. I will still create blogs in the periods up to publication so please keep checking back.
Finally, I thank you all for visiting my site and I hope you find it useful.
