My new e-book: Internet Routing with BGP

Thu, 27 Oct 2022 15:37:32 GMT

The book will be released the week of 17 November and it can be pre-ordered now from Apple Books in 51 countries and Amazon Kindle world-wide for US$ 9.99 / EUR 9.99.

The book on Amazon's various stores: AU - BR - CA - DE - ES - FR - IN - IT - JP - MX - NL - UK - US

Description:

The internet is “a network of networks”. It's made up of tens of thousands of largely independent networks, but somehow the users of one network can communicate with the users of any of the other networks. The Border Gateway Protocol (BGP) is the glue that binds these disparate networks together.
BGP is a routing protocol: its main job is to allow each network to learn which ranges of IP addresses are used where, so packets can flow along the correct route.
However, BGP has a more difficult job to do than other routing protocols. Yes, it has to make the packets reach their destination, but BGP also has to pay attention to the business side: those packets only get to flow over a network link if either the sender or the receiver pays for the privilege.
This book covers the fundamentals of the technical side of BGP, and also looks at the intersection between the technical and business aspects of internet routing.

You can read several sample chapters in PDF format or as an EPUB e-book. If you have any questions or want to receive an email when the book comes out, email me.

If you're a journalist, blogger or podcaster and would like to receive a preview copy, also let me know.

Time to write a new BGP book

Wed, 28 Sep 2022 14:04:07 GMT

20 years ago this month, my book BGP: building reliable networks with the Border Gateway Protocol was published by O'Reilly.

My 20 author copies of the book arrived a bit later:

Back in those days, publishers would only order a print run if they thought they could sell those copies in a reasonable amount of time. (I think print runs of about 1000 copies to be sold within a year.) If not, no more print runs, and the book would be out of print.

But right around the time sales dipped below the levels required for continued print runs, it started to become possible to have books printed on demand. These days, print on demand shops will print a single book on demand, and you wouldn't know the difference between such a book and a traditionally printed one. So it looks like the old book will be available "in print" forever.

But isn't all the info in the book completely outdated by now?

Perhaps surprisingly, a large part of the book is still current and relevant. When the book was published, BGP version 4 had been around for about a decade. And BGP version 4 is still what we use today. But there have been many (optional) additions to the protocol, and the environment in which BGP finds itself today has evolved.

So time for something new. However, doing an update of the existing book was not in the cards.

So instead, I'm currently writing a new BGP book. This one will be shorter and focus on core BGP topics. It will also have lots of examples that you can try out yourself in a "BGP mini lab".

Keep an eye on this page for updates.
