The present invention provides a tunnel packet loss detecting method, apparatus and network communication device. The transmitting frequency of transmitting detecting request packets at a head node is improved, and the quantity statistic and report of transmitted and received packets are performed at each node in a tunnel, so that a quick and exact tunnel packet loss detecting is achieved. The present invention can be applied in a two-way tunnel and a one-way tunnel, and can perform a statistic of transmitted and received packets in a tunnel for each node in a link, and therefore the specific packet loss location and quantity can be exactly determined, and the network fault point can be quickly located. A much convenient way is provided for the engineering maintenance, and requirements of the network operation and maintenance can be satisfied. |
