Stanislav Shalunov is an Internet architect who designed the new congestion control in BitTorrent (uTP/LEDBAT). In the beginning of 2011 he co-founded Open Garden. Open Garden connects smartphones and other devices into a self-organizing and self-optimizing mesh network. This peer-to-peer network improves users’ coverage and speed.

In 2000-2006, Stanislav was with Internet2, where he chaired the transport working group, led the open source initiative, and did seminal work in evaluating Quality of Service technologies, which proved to be of significant value to a broad coalition, including Internet2, which promoted net neutrality in policy discussions in Washington. His insights were very helpful to the debate, and provided the foundation for Internet2’s arguments made before the Senate Commerce Committee.

Stanislav's contributions to the field of computer security range from vulnerability discovery (e.g., root hole in the default install of most Unix systems) to tools (e.g., the secure temporary directory cleaner, stmpclean) to analysis of TCP resource consumption. Stanislav's netkill tool can still bring down any web server with the attacker requiring very modest resources, despite having been first published in 2000.

Stanislav is an author of RFC 4656 on One-Way Active Measurement Protocol (OWAMP), also RFC 4737, RFC 3763. Among other contributions to network measurement, he developed a measurement tool called Thrulay, the unique feature of which is the measurement of delays experienced by TCP traffic end-to-end. Thrulay revealed static queue buildup in the Linux TCP stack.

Stanislav is a mathematician by training and is interested in startups and entrepreneurship.
