¿µ¹®³»¿ë¿ä¾à The standard defines an overall architecture for DetNet, which provides a capability for the delivery of data flows with extremely low packet loss rates and bounded end-to-end delivery latency in enterprise networks under a single administrative control such as campus-wide networks and private WANs. DetNet operates at IP layer and delivers service over lower layer network technologies such as MPLS and IEEE 802.1 Time-Sensitive Networking (TSN). DetNet accomplishes these goals by dedicating network resources such as link bandwidth and buffer space to DetNet flows and/or classes of DetNet flows, and by replicating packets along multiple paths. Unused reserved resources are available to non-DetNet packets as long as all guarantees are fulfilled.
