Abstract:
1. A method for identifying conference media traffic comprising: receiving a plurality of dummy packets, each of the dummy packets comprising a timestamp; matching at a service control engine, without extracting payload information from the dummy packets and without extracting a packet type, a series of the plurality of dummy packets to a signature key associated with the time of day corresponding to a timestamp of one or more of the plurality of dummy packets, the signature key defined by a pattern corresponding to a series of packets, wherein the pattern comprises a first size of a first one of the series of packets and a second size of a second one of the series of packets; in response to matching the series of the plurality of dummy packets to the signature key, extracting a first identification different from the signature key from one or more of the plurality of dummy packets; determining that a second identification associated with one or more encrypted media packets matches the first identification; associating one or more encrypted media packets with a conference in response to determining that the first identification matches the second identification; wherein the first identification and the second identification each comprise a source identification and a destination identification; and wherein the source identification and the destination identification are Internet Protocol (IP) addresses.
