The present invention provides a system, an apparatus, and a method for transmitting a multicast service. The system includes: a first multicast ring, including a first node, a second node and at least one third node; and a second multicast ring, including a first node, at least one fourth node, and a second node that are connected in sequence, where each of the first node and the second node includes: a first port and a third port, configured to receive and forward a multicast service on the first multicast ring; and a second port, configured to: when serving as an active port, forward the multicast service received from the first multicast ring to the second multicast ring, and when serving as a standby port, block forwarding of the multicast service received from the first multicast ring to the second multicast ring, where in normal cases, one port of the second port of the first node and the second port of the second node is an active port, and the other port of the second port of the first node and the second port of the second node is a standby port. In the present invention, an active port and a standby port are provided for aggregation nodes of a multicast ring, which increases the security of a system. |
