Allison Mankin is the Director of Verisign Labs. Before coming to Verisign, she most recently worked at the Johns Hopkins Applied Physics Laboratory on DNSSEC and TCP security. Before Hopkins, she was a Program Director in the Computer and Network Systems Division at the National Science Foundation, co-directing the Future Internet Design (FIND) program among others.

Allison has worked on Internet infrastructure, security and transport research since the mid-80s. With funding from Sprint and Microsoft, she and collaborators contributed in significant ways to DNS and BGP security, internet multimedia, congestion control and IPv6 design.

Allison has been active in the Internet Engineering Task Force (IETF) and other organizations since early on in the development of the Internet. At IETF she served on the Internet Engineering Steering Group for a total of 10 years: Transport Area Director 1993-1997, Transport Area Director 2000-2006 and IP Next-Generation Area Director 1993-1995. With Scott Bradner, Allison co-led the IETF’s process for selecting IP Next Generation that led to the IPv6 protocol. In addition to IPv6, Allison managed robust standards development for TCP, VoIP, RSVP and IP storage, to name just a few. Allison founded and co-chaired the Reliable Multicast Transport (rmt) and Geolocation Privacy (geopriv) working groups and the Process and Tools (proto) team.

Based always in the DC area, Allison also worked at the Mitre Corporation, USC/ISI, Bell Labs, Shinkuro and a few other organizations. She spent almost eight years establishing network research for USC/ISI at the ISI-East location, where her work included directing an open-source, open-membership WAN testbed called CAIRN with 50-plus sites in the U.S. and U.K., which has been recognized as the precursor of PlanetLab. She was one of the inventors of the MBONE, which introduced the notion of a virtual network topology based on engineered tunnels, as well as enabling the spread of packet multimedia tens to hundreds of participants and of the Digital Amphitheater, a tool for video conferences for 10s-100s of participants.
