Plane: Transport

Layer: Network and Data Link Layers

Requirement If information is communicated on IP, QoS class should be specified in each communication for smart grid. 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 requirement Required in the case of transport on NGN or managed IP network

May Optionally in other casesBackground Information for smart grid includes critical data which is

sensitive of delay, delay variation, and loss. Therefore, performance on WAN should be clarified.

Reference ITU-T Y.1541Gap analysis Currently, 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.
