An automotive network comprising: a first network node adapted to generate and transmit data packets of a first traffic class; a second network node adapted to receive data packets of a second traffic class; and a network device, included in a network switch, adapted to process data packets transmitted between the first and second nodes, the network device further adapted to: intercept data packets of a first traffic class transmitted by the first network node and addressed to the second network node, convert the intercepted data packets into data packets of a second traffic class, wherein the network is an Audio Video Bridging, AVB, network, and wherein the first and second traffic classes are Stream Reservation, SR, classes, and wherein the first traffic class is AVB class A and the second traffic class is an AVB traffic class lower than AVB class A, wherein transmission of data of the first traffic class causes a higher processing load on a recipient node than the second traffic class, and transmit the converted data packets to the second network node, wherein the second network node is designed for the second traffic class, wherein the network is a closed network containing a single network switch, thereby allowing the converted data packets to satisfy the latency requirements of the first traffic class. a first network node adapted to generate and transmit data packets of a first traffic class; a second network node adapted to receive data packets of a second traffic class; and a network device, included in a network switch, adapted to process data packets transmitted between the first and second nodes, the network device further adapted to: intercept data packets of a first traffic class transmitted by the first network node and addressed to the second network node, convert the intercepted data packets into data packets of a second traffic class, wherein the network is an Audio Video Bridging, AVB, network, and wherein the first and second traffic classes are Stream Reservation, SR, classes, and wherein the first traffic class is AVB class A and the second traffic class is an AVB traffic class lower than AVB class A, wherein transmission of data of the first traffic class causes a higher processing load on a recipient node than the second traffic class, and transmit the converted data packets to the second network node, wherein the second network node is designed for the second traffic class, wherein the network is a closed network containing a single network switch, thereby allowing the converted data packets to satisfy the latency requirements of the first traffic class. intercept data packets of a first traffic class transmitted by the first network node and addressed to the second network node, convert the intercepted data packets into data packets of a second traffic class, wherein the network is an Audio Video Bridging, AVB, network, and wherein the first and second traffic classes are Stream Reservation, SR, classes, and wherein the first traffic class is AVB class A and the second traffic class is an AVB traffic class lower than AVB class A, wherein transmission of data of the first traffic class causes a higher processing load on a recipient node than the second traffic class, and transmit the converted data packets to the second network node, wherein the second network node is designed for the second traffic class, wherein the network is a closed network containing a single network switch, thereby allowing the converted data packets to satisfy the latency requirements of the first traffic class.
