TRANSPARENT BRIDGE DEVICE

摘要

The device provides protection for VoIP or like time-sensitive traffic. Packets arriving at a network interface in the data link layer are inspected to identify signaling packet, which are then queued for further analysis. The signaling packets are analyzed for compliance with adaptive criteria to determine whether the packets are considered safe to pass to a user, and the signaling packets failing to meet the adaptive criteria are rejected. The adaptive criteria based are updated based on historical data pertaining to the signaling packets from the same source address for the same user account.
