About the Technical Editors Anthony Kwan is the director and executive project manager of infrastructure for HTA; CCNP, CCDP, MCSE, Master ASE, MCNE, CCIE(written). He has ten years of experience in the internetworking industry. He designed and built a number of secured enterprise datacenters with an upward budget of $120 million. He also directed a number of consulting firms in building a Network Infrastructure and Technology consulting practice. He is a frequent contributor to Cisco Press and other publications specializing in networking technology. He can be reached at atonio888@yahoo.com. Suresh Subbarao has worked in the networking area for the last 10 years. He is currently a network engineer at Cisco Systems focusing on security services for Service Providers with a special emphasis on IPSec VPNs. Michael Sullenberger received a bachelor of science degree in mathematics from Harvey Mudd College in 1981. He started working with computer networks at the Stanford Linear Accelerator Center (SLAC) in 1981 as a Fortran programmer and as a user of the BITnet network, an early world wide 9600 baud network. At SLAC Michael also managed DEC VMS computers and gained knowledge of the DECnet and LAT protocol. He was also part of the introduction of Ethernet and FDDI networks to SLAC. In 1988 Michael moved to the networking group, where he assisted in transforming a large bridged, primarily DECnet, network to a routed multi-protocol, primarily TCP/IP, network. In 1994, he left SLAC to work for a small company, TGV, that wrote TCP/IP stacks and applications for Open VMS and Windows systems. At TGV he worked in technical support where he learned the details of TCP/IP from the IP layer through the Application layer. TGV was bought by Cisco in 1996, and Michael moved into the Routing Protocols group, where he enhanced his knowledge of TCP/IP by adding information on the link-layer and IP routing protocols. In 1998, Michael moved to the Escalation Team at Cisco, where he continues to expand his TCP/IP knowledge in areas such as NAT, HSRP, GRE and IPsec Encryption. In 2000, he started a project, as the principle architect, that became the Cisco Dynamic Multipoint VPN (DMVPN) solution for scaling IPsec VPN networks. In 2004, the DMVPN solution won the Cisco Pioneer Award. Michael continues to this day working on enhancing DMVPN as well as designing and troubleshooting DMVPN and IPsec networks. Also starting in 2000 Michael has been a speaker each year at the Cisco Networkers Conferences in the area of site-to-site IPsec and DMVPN networks.
