The invention provides methods and systems for providing priority processing to critical data as the data is transmitted across a network. A plurality of Internet protocol (IP) packets, each of which contains data and priority information, are received at a first router. The data contained in the IP packets is then encapsulated into frame relay frames containing the priority information. The frame relay frames are transmitted from the first router to a frame relay network in a manner determined by the priority information included in the frame relay frames. The frame relay frames are then transmitted across a frame relay network to a second router in a manner determined by the priority information included in the frame relay frames.
