Deterministic ethernet protocols
Web1. Time synchronization. All network devices and hosts can synchronize their internal clocks to an accuracy between 1 µs and 10 ns. Synchronization is accomplished using some … TTEthernet network devices implement OSI Layer 2 services, and therefore it claims to be compatible with IEEE 802.3 standards and coexist with other Ethernet networks and services or traffic classes, such as IEEE 802.1Q, on the same device. Three traffic classes and message types are provided in current TTEthernet switch implementations:

Deterministic Networking (DetNet) is an effort by the IETF DetNet Working Group to study implementation of deterministic data paths for real-time applications with extremely low data loss rates, packet delay variation (jitter), and bounded latency, such as audio and video streaming, industrial … See more Standard IT infrastructure cannot efficiently handle latency-sensitive data. Switches and routers use fundamentally uncertain algorithms for processing packet/frames, which may result in sporadic data flow. … See more Resource allocation To reduce contention related packet loss, resources such as buffer space or link bandwidth can be assigned to the flow along the path from source to destination. Maintaining adequate buffer storage at each node also … See more Applications from different fields often have fundamentally similar requirements, which may include: 1. Time synchronization at each node (routers/bridge)across the entire network, with accuracy from nanoseconds to microseconds.
