摘要
A method for detecting connectivity of user node interface in a virtual private network includes: acquiring a configuration parameter used for detecting connectivity of a user node interface between a source address and a destination address in the virtual private network; transmitting an Internet Control Message Protocol (ICMP) request packet from the source address to the destination address through the configuration parameter, and receiving an ICMP response packet responded by the destination address; and after receiving the ICMP response packet responded by the destination address, calculating a round-trip time value of a link between the source address and the destination address, and then collecting statistics on the connectivity of the user node interface between the source address and the destination address according to the round-trip time value obtained by calculation.
