Document Type and Number:
WIPO Patent Application WO2003003753
Kind Code:
A3
Abstract:
Method for protecting against overload of a packet switching network node of a communication network, said packet switching network node being provided with resources for processing of requests and with an overload protection task (OPT) for protection of said resources from overload, said resources comprising at least one input queue (Ql, ..., Q4) for requests to be processed, a processor (CPU) for request processing and a memory (M) for storing data related to request processing, said resources for processing being limited, wherein said network node, in particular said overload protection task (OPT), performs the steps of: monitoring a load status of said resources, detecting, by means of the load status, any overload situation arising at the monitored resources, and determining, in the case of a detected overload situation, dependent on predetermined rules, an overload dissolving measure.
