Abstract
Systems and methods performed by an IP telephony device or an element of an IP telephony system mask the data contained in data packets bearing the media of an IP telephony communication to prevent an Internet service provider from identifying the data packets as carrying the media of an IP telephony communication. The systems and methods can also modify the size of data packets and/or modify the data transfer rate of a stream of data packets bearing the media of an IP telephony communication to prevent an Internet service provider from identifying the stream of data packets as bearing the media of an IP telephony communication.
Claims25
A method of modifying the size of one or more data packets bearing the media of an IP telephony communication, comprising
- receiving one or more data packets bearing the media of an IP telephony communication, the one or more data packets conforming to a standard used for IP telephony communications;
- and
- modifying a size of at least one of the received data packets based on a key that has been established for the IP telephony communication in such a manner that a modified data packet does not resemble data packets that conform to the standard used for IP telephony communications.
A system for modifying the size of one or more data packets bearing the media of an IP telephony communication, comprising
- means for receiving one or more data packets bearing the media of an IP telephony communication, the one or more data packets conforming to a standard used for IP telephony communications;
- and
- means for modifying a size of at least one of the received data packets based on a key that has been established for the IP telephony communication in such a manner that a modified data packet does not resemble data packets that conform to the standard used for IP telephony communications.
A system for modifying the size of one or more data packets bearing the media of an IP telephony communication, comprising
- a receiving unit that receives one or more data packets bearing the media of an IP telephony communication, the one or more data packets conforming to a standard used for IP telephony communications;
- a processor configured to modify a size of at least one of the received data packets based on a key that has been established for the IP telephony communication in such a manner that a modified data packet does not resemble data packets that conform to the standard used for IP telephony communications.
A method of correcting the size of one or more data packets bearing the media of an IP telephony communication, comprising
- receiving one or more data packets bearing the media of an IP telephony communication, wherein the size of the one or more data packets has been altered based on a key that has been established for the IP telephony communication in such a manner that an altered data packet does not resemble data packets that conform to a standard used for IP telephony communications;
- and
- correcting the size of the received data packets based on the key so that corrected data packets conform to a standard used for IP telephony communications.
A system for correcting the size of one or more data packets bearing the media of an IP telephony communication, comprising
- means for receiving one or more data packets bearing the media of an IP telephony communication, wherein the size of the one or more data packets has been altered based on a key that has been established for the IP telephony communication in such a manner that an altered data packet does not resemble data packets that conform to a standard used for IP telephony communications;
- and
- means for correcting the size of the received data packets based on the key so that corrected data packets conform to a standard used for IP telephony communications.
A system for correcting the size of one or more data packets bearing the media of an IP telephony communication, comprising
- a receiving unit that receives one or more data packets bearing the media of an IP telephony communication, wherein the size of the one or more data packets has been altered based on a key that has been established for the IP telephony communication in such a manner that an altered data packet does not resemble data packets that conform to a standard used for IP telephony communications;
- and
- a processor that corrects the size of the received data packets based on the key so that corrected data packets conform to a standard used for IP telephony communications.
