The subject matter described herein relates to methods, systems, and computer readable media for discarding messages during a congestion event. One method includes registering a traffic congestion policy for handling traffic associated with an application during congestion. The method further includes determining a first congestion level associated with a congestion event. The method also includes determining message rates of messages associated with similar message priority values, wherein the message priority values are determined using the traffic congestion policy. The method further includes discarding a first message using the message rates, the first congestion level, and a message discard algorithm, wherein the message discard algorithm is determined using the traffic congestion policy.
