A Toolset for the Internet of Threads (IoTh): Fine-Grained IPv6 Networking in User Space

The Internet of Threads (IoTh) is an experimental networking model that assigns full IPv6 identities—addresses, routing behavior, and protocol stacks—to processes or even individual threads. Instead of containers or VMs, IoTh leverages user-space TCP/IP stacks.

This talk presents the open IoTh toolchain and its networking architecture: * libioth: the core IoTh library: a pluggable TCP/IP stack framework for user-space nodes. * nlinline: A quick and clean API for NetLink networking configuring (implemented in a header file). * libnlq: Netlink configuration library (for netlink clients and servers). * iothconf – Simple and expressive configuration for IoTh stacks. Common network setups can be defined with a single character string. * iothdns + iothnamed: DNS services supporting hash-based addressing and OTIP (One-Time IP) models * namedhcp: a DNS-driven DHCPv6/4 server for stateful, reproducible address assignment * otip-utils: tooling for ephemeral, privacy-oriented IPv6 addressing * iothradvd: an embeddable RA daemon for user-space IPv6 configuration
