Document Type and Number:
WIPO Patent Application WO/2018/214423
Kind Code:
A1
Abstract:
The present invention relates to the technical field of POTN transmission, and disclosed are a POTN service forwarding system and forwarding method. The system comprises an ethernet tributary unit, switch unit, and OTN line unit. In the present invention, POVE is instantiated as a multicast in an uplink direction to enable bridge connection, a packet service employs the multicast as an exit port of an uplink service channel, and an OTN service employs the multicast as a source port of interaction with an ODUk channel. In a downlink direction, the POVE is instantiated as VLANDOMAIN to enable bridge connection, the OTN service maps a line-side backplane port connected to the ODUk channel to the VLANDOMAIN, and the packet service employs the VLANDOMAIN as a common physical port to complete classification for accessing the packet service. Also disclosed in the present invention is a POTN service forwarding method.
