 Explicit routes can be established with RSVP-TE, Segment Routing, IS-IS, MPLS-TE label-switched path (LSP), or a Software Defined Networking layer.IETF Traffic Engineering Architecture and Signaling (TEAS) work group maintains MPLS-TE LSP and RSVP-TE protocols.These traffic Engineering (TE) routing protocols translate DetNet flow specification to IEEE 802.1 TSN controls for queuing, shaping, and scheduling algorithms, such as IEEE 802.1Qav credit-based shaper, IEEE802.1Qbv time-triggered shaper with a rotating time scheduler, IEEE802.1Qch synchronized double and triple buffering, 802.1Qbu/802.3br Ethernet packet pre-emption, and 802.1CB frame replication and elimination for reliability.
