METHOD AND APPARATUS FOR EXPLORING FRONTHAUL TOPOLOGY

摘要

Embodiments of the present invention relate to a method and an apparatus for probing a fronthaul topology. The method includes: sending, by a baseband device, a source route probe frame; receiving a destination route probe frame, where the destination route probe frame is formed after a first transport network device records first port information in the source route probe frame and a second transport network device records second port information in the source route probe frame; and determining, by the baseband device, probe information according to the destination route probe frame, and sending the probe information to an element management system EMS. According to the method and the apparatus for probing a fronthaul topology in the embodiments of the present invention, the baseband device sends, to a radio frequency device by using the transport network devices in a transport network, the route probe frame used to probe a path; the transport network devices record the related port information and return the route probe frame to the baseband device; and the baseband device reports the probe result to the wireless EMS, so that the wireless EMS can determine information about a topology between a wireless device and a transport network device, and determine a connection relationship between ports of various devices, according to the probe result.
