Provided are a method, system and network device for quality of service (QoS) negotiation in cross-medium networks in the invention. The method includes: receiving, via an interface supporting multiple access modes, a source address and a destination address from an application layer; obtaining, based on the pre-collected network topology information and network resource occupation situation, the information of the best path from the source address to the destination address; mapping, according to the protocol corresponding to the access mode of the physical layer, the best path information to a corresponding port, which makes the port perform QoS negotiation. With the embodiments of the invention, the QoS negotiation speed can be accelerated and the service connection speed can be increased. |
