4G RTP APPARATUS SYSTEM AND METHOD FOR DETECTING A RTP TUNNELING PACKET IN 4G MOBILE NETWORKS

摘要

RTP tunneling packet detector, system and method in 4G mobile network are provided. The RTP tunneling packet detector detects a first source IP, a first source port, a first destination, and a second destination from the GTP-U packet when a GTP (GPRS Tunneling Protocol)-U packet includes an RTP IP, and a session information storing session information including a packet information extracting unit for extracting a first destination port, a second source IP, a second source port, a second destination IP, a second destination port, and detection time information Wherein the first source IP, the first source port, the first destination IP, and the first destination port all correspond to the second source IP, the second source port, the second destination IP And a session information management unit for updating the detection time information in the session information when the second port is identical to the second destination port, a session information management unit for detecting an abnormal data packet using the detection time information in the session information, And a packet processor for processing the abnormal data packet according to a detection result of the session information analyzer.;
