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, system and transport unit to combine and transport multiple variable data rate LAN streams and fixed data rate voice streams through a plurality of transmission links used as a conduit for transmission of data between local area networks are disclosed. Combining both TDM and packetized network traffic into packets for transfer between LANs using a framed protocol for the transfer is further disclosed.
