Method, system and device for processing device overload in communication network

摘要

A method for processing device overload in a communication network includes: a device involved in a service connection checking in real time whether processing capability of the device exceeds an overload threshold set in the device, and sending to a neighboring device of the device an overload alarm message containing an address of the device if the processing capability of the device exceeds the overload threshold; the neighboring device restricting traffic passing through the device after receiving the overload alarm message. The method of the present invention enables the device involved in the service connection to automatically lead the establishment of the subsequent service connection reasonably, which improves the operation efficiency of network and shortens the processing delay of service connection.
