tipc is a user-space configuration tool for TIPC (Transparent Inter-process Communication). It utilizes the TIPC netlink API in the kernel to fetch data or perform actions. The tipc tool has somewhat similar syntax to the ip tool meaning that users of the ip tool should not feel that unfamiliar with this tool.
