Abstract: The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as a long term evolution (LTE). A method for managing congestion in a first node in a wireless communication system is provided. The method includes receiving status information from each of nodes configuring a network with the first node, receiving information about a service requirement criterion from a second node as one of the nodes, acquiring additional path setup information for the second node based on the status information received from each of the nodes and the information about the service requirement criterion received from the second node, and transmitting the acquired additional path setup information to the second node.
