| 摘要 |
Disclosed is a communication node device constituting a communication system performing multicast, which is characterized by that: when having forwarded data to a child node subordinate to it along a normal distribution path, it sets a retransmission timer also with respect to a child node on a redundant distribution path; and when having received data, it sends a reception confirmation message to both the parent node of the normal distribution path and a parent node of the redundant distribution path. |
