Title:
LINK DETECTION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/020287
Kind Code:
A1
Abstract:
Provided in an embodiment of the invention are a link detection method and device. The method comprises: receiving, by a relay device, multiple first continuity check message (CCM) packets transmitted by multiple maintenance end points (MEPs), wherein the first CCM packet transmitted by each MEP carries an ID of the MEP; performing, by the relay device, combination processing on the multiple first CCM packets to generate a second CCM packet, wherein a source media access control (MAC) address of the second CCM packet is an MAC address of the relay device, and the second CCM packet carries the IDs of the multiple MEPs; and transmitting, by the relay device, the second CCM packet to an RMEP so that the RMEP determines, according to the second CCM packet, link continuity between itself and the multiple MEPs. The link detection method and device provided in the embodiment of the invention can reduce the number of CCM packets accumulated on a link, thereby solving a problem in which the CCM packets occupy too much bandwidth on the link.
