Abstract:
1. An admission scheme control device for selectively admitting voice data packets generated by a pre-authenticated voice device into a packetized voice communication network from a into a Voice-Over-Internet-Protocol communication network and into a network external of the Voice-Over-Internet-Protocol communication network, said packetized voice communication network being composed comprised of a plurality of pre-authenticated voice Voice-Over-Internet-Protocol devices each having a MAC address and said network external to said Voice-Over-Internet-Protocol communication network is an untrusted network comprised of a plurality of non-authenticated Voice-Over-Internet-Protocol devices, the admission scheme, comprising control device executing the steps of: receiving data packets from a communication network carrying voice data packets and other packet traffic, said each voice data packets each packet including a MAC address indicative of the source device of said voice data packet; checking a traffic rate of the voice data packets from at least one of the plurality of pre-authenticated Voice-Over-Internet-Protocol devices, admitting voice data packets into the Voice-Over-Internet-Protocol communication network if the traffic rate of the checked voice data packets from at least one of the plurality of pre-authenticated Voice-Over-Internet-Protocol devices does not exceed a prescribed maximum, where the voice data packets have a MAC address corresponding to that of a respective pre-authenticated device of the plurality of pre-authenticated devices, into the packetized voice communication network and admitting data packets into a communication network external of the Voice-Over-Internet-Protocol communication network where the data packets have a non-corresponding MAC address, wherein if the traffic rate of the checked voice data packets exceeds the prescribed maximum, a corresponding originating device of the checked packets is disconnected from the packetized voice Voice-Over-Internet-Protocol communication network and re-authenticated.
