Acknowledgments

There are so many people to thank. To begin with, we'd be remiss if we didn't extend heartfelt thanks to the entire MPLS development team for their continual sharing of expertise, often in the face of our daunting cluelessness. Special thanks go to Carol Itturalde, Rob Goguen, and Bob Thomas for answering our questions, no matter how detailed, how obscure, or how often we asked them.

We also want to thank our primary technical reviewers—Jim Guichard, Jean-Philippe Vasseur, and Alexander Marhold. Their guidance and feedback kept us on course.

We'd also like to thank the folks who reviewed parts of this book for accuracy and relevance. In alphabetical order: Aamer Akhter, Santiago Alvarez, Vijay Bollapragada, Anna Charny, Clarence Filsfils, Jim Gibson, Carol Iturralde, Francois Le Faucheur, Gwen Marceline, Trevor Mendez, Stefano Previdi, Robert Raszuk, Khalid Raza, Mukhtiar Shaikh, George Swallow, Dan Tappan, Mosaddaq Turabi, Siva Valliappan, Shankar Vemulapalli, and Russ White.

Eric wants to thank the members of PSU Local #1 for confirming and correcting his assumptions about how large Internet backbones really work.

Our last thanks go to the Cisco Press editing team—specifically, to Chris Cleveland and Brett Bartow for shepherding us through this process. It took over a year to do, and we couldn't have done it without them.
