The present invention relates to the field of communication technologies, and discloses a bandwidth information notification method, a service processing method, a network node, and a communication system. The bandwidth information notification method includes: obtaining current bandwidth information of a link; and sending the bandwidth information to an endpoint of a service connection through the service connection which passes through the link, so that the endpoint of the service connection adjusts a service policy according to the bandwidth information. Through the technical solutions provided in the embodiments of the present invention, an endpoint of a service connection which passes through a microwave link may obtain bandwidth information of the microwave link, where the bandwidth information is obtained after adaptive modulation of the microwave link. |
