3 ITU-T Focus Group IMT-2020 Deliverables

The Initiative on Joint SDOs/Fora Industry Harmonization on Unified Standards for AMC, SDN, NFV, E2E
Service Orchestration and Big-Data Analytics for AMC – all viewed in their combined roles as Software-
Oriented Enablers for 5G, is driven by a joint SDOs/Fora White Paper that is identifying the items requiring
standard harmonization, to reduce “silos”, duplication of work and divergence [Ref.6.1.4-2].

6.1.5 Standardization activities at IETF on Detnet

6.1.5.1 Introduction
The Deterministic Networking (Detnet) Working Group in IETF was established in October, 2015. The work
focuses on creating multi-hop path over Layer 2 bridged and layer 3 routed segment with deterministic
properties in latency, packet loss, jitter, and high reliability, which triggers by the need to support time
sensitive services in IP network, usually these kinds of services require bounds on latency, loss and etc. The
mission-critical IoT services in 5G such as factory automation, smart grid are typical use cases of Detnet. To
support these critical packet flows, it is required to guarantee the absolute maximum and minimum end to
end latency across the network, and a better packet loss ratio than the traditional requirements. In addition,
the latency and packet loss requirements in transport network in 5G cellular radio network also become more
stringent compared with the cellular radio network today. To create the path with bounded latency and
packet loss requirements in the IP transport network, Detnet may be a potential solution. For instance,
Detnet can be applied to provide with multi-hop path between eNBs with deterministic latency, since
CoMP( coordinated multipoint transmission/reception) identified as a technology in 5G can benefit from the
coordinated scheduling of different cells only if the signalling delay between eNBs is within 1-10ms.The first
step of Detnet is to find the solution for networks that are under a single administrative control or within a
closed group of administrative control. The solution proposed by the Detnet will be applicable not only to
campus-wide networks, but also to the private WAN.
