Claim:
1. A method for determining a multicast path, comprising: receiving, by a multicast address translation router, a first multicast join request packet, wherein the first multicast join request packet is an Internet Protocol (IP) version 4 (IPv4) packet and a multicast address of the first multicast join request packet is an IPv4 multicast address, or the first multicast join request packet is an IP version 6 (IPv6) packet and a multicast address of the first multicast join request packet is an IPv6 multicast address obtained by performing IP version translation on an IPv4 multicast address; and determining, by the multicast address translation router, a shorter path between a first path and a second path, wherein the first path is a path between an IPv4 interface of the multicast address translation router and a multicast data providing node corresponding to the first multicast join request packet, and the second path is a path between an IPV6 interface of the multicast address translation router and the multicast data providing node corresponding to the first multicast join request packet.
