Provided in an embodiment of the present invention are a path connectivity test method and device. The method comprises: a receiving node receives an echo request transmitted by a transmitting node, the echo request comprising an identifier of a service function (SF), the packet header of the echo request comprising information on a path to the SF, the path information comprising a segment identifier (SID) of the SF; when the receiving node determines, on the basis of the SID of the SF, that the SF is associated with the receiving node, determining whether the SID corresponding to an SF stored by the receiving node is consistent with the SID of the SF contained in the path information; if so, then determining that the path to the SF has connectivity, and the receiving node transmits a first echo reply to the transmitting node, the value of a return code carried in the echo reply indicating that the path to the SF has connectivity. The invention realizes an effective test of path connectivity. |
