Riverstone introduced a Loop Protection System (LPS) designed to safeguard carrier networks from customer premise generated failures by creating a virtual demarcation point for the carrier. Riverstone’s Loop Protection System inspects packets entering the carrier network to determine if they have already been sent to the corporate network. If the system finds that the same packets are being sent, rather than exposing the carrier network to a slowdown, the Loop Protection System isolates the interface to the corporate network. The system then periodically reconnects to the corporate network to detect if the loop has been removed.
