Abstract: This application provides a communication method and apparatus, and pertains to communication technologies. In this method, a network element on a network side, for example, a first network element, may obtain network congestion information of a service flow, to determine a possibility that congestion occurs on a current network and perform supervision. For example, after a network congestion degree becomes higher, for example, a possibility of network congestion has reached a level that an application side needs to reduce the possibility of network congestion by adjusting transmission of the service flow, if the first network element determines, by monitoring the transmission of the service flow, that the application side does not adjust the transmission of the service flow, the first network element can manage and/or control the transmission of the service flow, to avoid network congestion and also ensure fairness between services, thereby ensuring user experience.
