Abstract
A communications network circuit through which data packets are flowing is identified by detecting a first message data packet inserted into the data packet flow by a user, and determining an endpoint destination address of the detected data packet. The circuit using the endpoint destination address is identified and a second message data packet containing the circuit identification information is sent to the destination address. A covert timing channel may be created, and one or more data packets containing circuit identification information may be sent through the covert channel.
Claims14
A method of identifying a communications network circuit through which data packets are flowing, the method comprising:
- detecting a first message data packet in the data packet flow, wherein the first message data packet is inserted into the data packet flow by a user;
- determining an endpoint destination address of the detected data packet;
- identifying the circuit using the endpoint destination address;
- and
- sending a second message data packet to the destination address, wherein the second message data packet contains the circuit identification information.
A method of identifying a communications network circuit through which data packets are flowing, the method comprising:
- creating a covert timing channel;
- and
- sending one or more data packets containing circuit identification information through the covert timing channel.
A computer program product for identifying a communications network circuit through which user data packets are flowing, comprising a computer readable storage medium having encoded thereon instructions that, when executed on a computer, cause the computer to:
- detect a first message data packet in the data packet flow, wherein the first message data packet is inserted into the data packet flow by a user;
- determine an endpoint destination address of the detected data packet;
- identify the circuit using the endpoint destination address;
- and
- send a second message data packet to the destination address, wherein the second message data packet contains the circuit identification information.
The computer program product of claim 13, wherein the computer readable storage medium has encoded thereon instructions that, when executed on a computer, causes the computer to determine if the circuit user is authorized to receive the circuit identification information before sending the second message data packet to the destination address.
