Network slicing telemetry support for slice queue statistics

Junos telemetry interface (JTI) supports slice queue statistics on network slices (logical networks). Network slicing enables network operators to define logical networks on a physical network. A slice comprises a set of nodes, links, and prefixes of a transport network. Subscribe to the native sensor /junos/system/linecard/cos/interface/slice/out-queue/ to export egress queue statistics.
