The Internet Protocol Journal - Volume 8, Number 2

From the Editor

The Internet is a constantly evolving environment which puts pressures on existing and evolving protocols. Any protocol changes must be carefully designed and even more carefully deployed to avoid any disruption to the running system. It is no longer possible to orchestrate a simple overnight switch, so engineers are considering various transition and evolution strategies. In this issue we bring you two examples of this kind of evolutionary protocol development.

Our first example relates to IP Version 6 (IPv6). A great deal of effort is going into the deployment of IPv6, and good transition strategies can help. Tejas Suthar explains how Multiprotocol Label Switching (MPLS) can be used for a transition from IPv4 to IPv6.

Our second example looks at a possible enhancement to the Border Gateway Protocol (BGP). BGP in its current form is already nearly ten years old, and calls for its replacement can be heard from network operators. Russ White discusses some possible changes that would not require a wholesale protocol replacement.

It is not every day that a book on punctuation becomes an international best seller, and it is certainly not common for IPJ to review such a noncomputer related book. But I think it is appropriate for several reasons. First, accurate punctuation is important not just for computer parsers, it is important for all professionals whether we are sending quick emails or writing project reports. Second, this is a really fun as well as informative book. And last, but not least, it gives me an opportunity to introduce you to Bonnie Hupton, who provides copy-editing services for this journal. Without her help, IPJ would be far less readable.
