Title:
METHOD FOR DETERMINING DF OF MULTICAST STREAM, DEVICE, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/078043
Kind Code:
A1
Abstract:
A method for determining a DF of a multicast stream, a device, and a system. In an EVPN scenario, a CE device is dual-homed or multi-homed connected to a plurality of PE devices. A first PE device is any one of the plurality of PE devices. After determining that a CE device connected to an Ethernet link has joined a multicast group of a multicast stream, the first PE device determines bandwidth occupancy conditions of a plurality of Ethernet links included in an ES to which said Ethernet link belongs, and then determines, according to the multicast stream bandwidth occupancy conditions of the plurality of Ethernet links, the PE device corresponding to the Ethernet link that occupies the minimum multicast stream bandwidth as the DF of the multicast stream. Thus, the present invention helps to improve the load sharing balance in multicast stream transmissions in an EVPN.
