A few months ago, I had that crazy idea to write a book about IP Multicast. It's a technology I always found very attractive, but unfortunately quite overlooked by most network professionals. There is already lot of great literature on the subject, so I wanted to bring something new; treating the subject in both a vendor neutral and network-layer independent way. In addition to the consequent theoretical aspect of multicast, I wanted to share my practical experience by covering tools and troubleshooting procedures.

Fortunately, or unfortunately, I will let you judge, I've no more spare time to continue the writing of this book. Recent updates in my professional career plan have shorten my spare time considerably; enough to ask myself if it's not more profitable to release the content I already wrote for free, so anyone can benefit of it.

I will keep the content structured, so I will first publish the introductory part about IP multicast in a single article, followed by the part about multicast addressing, the troubleshooting chapter(s), and finally, if the time permits, I will publish a few case-studies. My contribution will also depend on the number of readers' feedback I will get. Note that I can also include your contribution to the article, therefore if you want to share some, don't hesitate to contact me.

IP multicast is still a frequently changing technology, so I may update the forthcoming articles when important or major changes (such as new address block allocations) are worth mentioning. In the meantime, stay tuned, the first article is only a few days away.
