Patent ID: 8284692

Claim:
A method for identifying the type of transport protocol of an IP communication session carried as a payload over a bearer between two intermediate nodes and providing control of network data transmission resources based on such identification, wherein the data traffic in the bearer is carried over a plurality of channels, the method comprising the steps of: intercepting the data traffic in a communication channel between the two intermediate nodes: monitoring one or more characteristics of the traffic for the communication channel by: monitoring the time between receptions of consecutive packets of the IP communication session; calculating a recent-average-time between consecutive IP packets for a group of recently received IP packets; and identifying a current time between a current received IP packet and a previously received IP packet; and comparing the recent-average-time with the current time; identifying the transport protocol used by an IP communication session, which is carried as payload over the communication channel, based on the traffic characteristics of the communication channel over time; if the difference between the recent-average-time and the current time falls within a first range of values, concluding that the transport protocol that is used by the IP session is of a first type; and if the difference between the recent-average-time and the current time falls within a second range of values, concluding that the transport protocol is of a second type.
