| 4 | 5 | Junxiao Shi | It provides: |
| 5 | 1 | Junxiao Shi | |
| 6 | 5 | Junxiao Shi | * a dataset of forwarder version information and global counters |
| 7 | 1 | Junxiao Shi | |
| 8 | 5 | Junxiao Shi | Forwarder Status datasets are available under namespace `ndn:/localhost/nfd/status`. |

| 12 | 5 | Junxiao Shi | General Status is published as a [[StatusDataset|Status Dataset]] at `ndn:/localhost/nfd/status/general`. |
