The invention provides a link detection method and device. The method comprises the following steps: setting a private line detection message sending period, private line timeout time and private line switching minimum time of a private line RPR port of a private line network segment; the private line detection message sending period is equal to a ring network detection message sending period of an RPR port of the RPR ring network; the special line timeout time is greater than the ring network timeout time and less than the special line timeout time; detecting a message sending period according to the private line link, and sending a keep-alive message through the private line section; receiving a keep-alive message sent by the direct connection neighbor node of the special line section through the special line RPR port; when the time that the keep-alive message is not received through the special line RPR port exceeds the special line timeout time; reading the last switching time of the special line RPR port
