Method for protecting a network from data packet overload
An internal network (16) is protected from being overloaded by an excessive number of data packets that originate from a source in an external network (10). In a preferred embodiment, data packet gate (20) receives each incoming data packet and determines whether it came from a trusted source. If it...

| Zusammenfassung: | An internal network (16) is protected from being overloaded by an excessive number of data packets that originate from a source in an external network (10). In a preferred embodiment, data packet gate (20) receives each incoming data packet and determines whether it came from a trusted source. If it was not from a trusted source, and the number of data packets received recently from the same source exceeds a threshold, then data packets from that source are rejected. Preferably, when incoming data packets from all non-trusted sources exceed another threshold, additional data packets from all non-trusted sources are rejected. |
