FIELD: data transmission and processing.
SUBSTANCE: invention relates to POTN transmission engineering. System comprises an Ethernet data transmission unit, a switching unit and a linear OTN unit. In the system, POVE instances are created as multicast forwarding in an uplink direction to provide a bridge connection, the packet service uses multicast as an output port of the service channel for outbound communication, and the OTN service uses multicast as a source of interaction with the ODUK channel. In the direction of incoming communication, POVE instances are created as a VLANDOMAIN to provide a bridge connection, the OTN service assigns a rear side network port connected to the ODUK channel with the VLANDOMAIN, and the packet service uses VLANDOMAIN as a common physical port for classification for accessing the packet service. Present invention also discloses a method of redirecting a POTN service.
EFFECT: possibility of redirecting POTN services and improving operational efficiency and stability of the system.
