With the development of Internet, various new applications and scenarios have made the cyberspace more complicated. Endless new applications and scenarios put forward deterministic Quality of Service (QoS) on existing networks. So as to solve the problem of deterministic QoS in existing networks, the IETF established the Deterministic Networking (DetNet) working group. IETF DetNet working group aimed at providing an answer to deterministic QoS requirement with support for deterministic worst-case delay and zero packet loss for DetNet flows. DetNet working group proposed resource allocation, explicit paths, and service protection mechanism to provide QoS requirements mentioned above.
