Title:
METHOD, APPARATUS AND DEVICE FOR ACCESSING CHANNELS ACROSS OLT SLICES, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/148330
Kind Code:
A1
Abstract:
The present invention provides a method, an apparatus and a device for accessing channels across OLT slices, and a storage medium. Said method comprises: upon receipt of a multicast join request corresponding to a logical slice and sent by an ONU, forwarding the multicast join request to a plurality of content providing platforms corresponding to the logical slice; on the basis of the multicast join request, respectively operating multicast forwarding table entries of a plurality of physical slices corresponding to the plurality of content providing platforms; and upon receipt of a multicast data stream which is issued by a target content providing platform on the basis of the multicast join request, sending the multicast data stream to the ONU on the basis of the multicast forwarding table entries. By means of the present invention, when multicast data on different content providing platforms is forwarded for an ONU which subscribes to a plurality of content providing platforms under a logical slice, forwarding planes of physical slices corresponding to the different content providing platforms are multiplexed, achieving the service requirements for the same ONU to access channels of IPTV servers of different content service providers.
