Required performance between edges of WAN on IP layer should be specified every application, and should be categorized into Classes 0, 1, 2, 3, 4, U according to ITU-T Y.1541 [ITU-T Y.1541]. Moreover, on data link layer, performance should be controlled to comply with IP layer performance. Type of requirementRequired in the case of transport on NGN or managed IP network May Optionally in other cases BackgroundInformation for smart grid includes critical data which is sensitive of delay, delay variation, and loss. Therefore, performance on WAN should be clarified. ReferenceITU-T Y.1541 Gap analysisCurrently, ITU-T Y.1541 does not mention smart gird in guidance for IP QoS classes. Since smart grid can be supported as an application on NGN or other managed IP network including utility network, smart grid should be added to guidance for IP QoS classes.
