Abstract: There is provided a technique of time-sensitive transmission of Ethernet traffic in IET-blind network. A source endpoint network node receives expedited and non-expedited Ethernet frames; for each non-expedited Ethernet frame: detects a pre-provisioned designated non-expedited tunnel with a destination endpoint network node corresponding to a destination address specified in the Ethernet frame, segments non-expedited Ethernet frame into a plurality of segments, encapsulates each segment in accordance with the designated non-expedited tunnel; and sends the encapsulated segments to the destination endpoint network node via the designated non-expedited tunnel. When the designated non-expedited tunnel is constituted by a plurality of successive sub-tunnels (e.g.

Abstract: A method and system of correcting a packet delay variation, PDV, of express traffic comprising high-priority express packets interspersed at a transmitter (2) by a preemption mechanism with a best-effort traffic comprising low-priority best-effort packets, wherein the method comprises the steps of: calculating (S1) at the transmitter (2) a preemption delay value, PRDV, which indicates a preemption delay, PD, introduced by the preemption mechanism; writing (S2) the calculated preemption delay value, PRDV, into a delay header field of a header of a high-priority express packet transmitted by said transmitter (2) via a signal line (4) to a receiver (3); extracting (S3) the preemption delay value, PRDV, from the delay header field of the header of the high-priority express packet received by the receiver (3) via the signal line (4) from the transmitter (2); calculating (S4) at the receiver (3) a variation compensation delay, VCD, value by subtracting the extracted preemption delay value, PRDV, from a predetermine
