Methods for efficient overload protection in 5g core networks

Abstract

Methods, non-transitory computer readable media, network traffic management devices and network traffic management systems that provide for efficient overload protection in 5G core networks are illustrated. With this technology, a load at a producer network function (NF) is monitored and in response to determining that the producer NF is overloaded, a plurality of types of network traffic flowing to the overloaded producer NF are monitored. An overloaded network traffic type is identified, which is a type of network traffic flowing to the producer NF that is of an amount that exceeds a first threshold amount above a first baseline amount of network traffic. An overloaded session is identified, which is a session having an amount of the overloaded network traffic type that exceeds a second threshold amount above a second baseline amount of network traffic. A mitigating action to reduce network traffic from the overloaded session is performed.
