METHOD FOR ROUTING DATA BURSTS WITH MULTI-PROTOCOL LABEL SWITCHING IN A RING DATA TRANSMISSION NETWORK AND A NETWORK NODE FOR THE REALIZATION OF THE METHOD

摘要

According to the present invention, a method for routing data bursts with multi-protocol label switching (MPLS) in a ring data transmission network and a network node for the realization of the method are proposed. The proposed method consists in providing the repeated routing for transmitting data bursts over the protected route in the network, assigning additional labels to the said data bursts, and detecting the additional labels at the network nodes that are located along the protected route. The additional labels in the data bursts provide a possibility to determine the network nodes at which the data bursts shall be removed from the protected route.
