US 7,352,746 B1 · Frame forwarding installation

Abstract

A frame forwarding installation on the side of a transmitting terminal refers to a header of a received frame and determines whether a host application is a real-time application. If the application is a real-time application, the received frame is sent to a plurality of paths in the direction of a destination. When a frame received from a path is transmitted to a destination terminal, a frame forwarding installation on the side of the destination terminal stores the identifier of this frame in a storage unit and, if a frame then newly arrives from a path, determines whether the frame identifier of this frame has been stored in the storage unit. If the newly arriving frame has been stored, it is regarded as being a frame already received and is discarded. If the newly arriving frame is not a frame that has already been received, the received frame is transmitted to the destination terminal and the identifier of this frame is stored.

A frame forwarding installation for sending a received frame to one of a plurality of paths conforming to a destination address contained in a header of the frame, which has been received from a transmitting terminal, comprising:

an application discriminating unit for referring to the header of the received frame and determining whether an application of a host layer in the transmitting terminal is a real-time application;
and
a frame transmitting unit for sending in duplicate the received frame to a plurality of paths in parallel in the direction of a destination if the application is the real-time application, and for sending the received frame to one of said plurality of paths in the direction of the destination if the application is not the real-time application.
