| 4 | 2 | Ashlesh Gawande | NLSR no longer uses a combined sequence number as [1523](https://redmine.named-data.net/issues/1523) has been merged. |
| 5 | It uses a separate sequence number for each type of LSA. |

| 7 | 1 | Vince Lehman | ## Combined Sequence Number |
| 8 | |||
| 9 | The sequence numbers for each LSA type are combined and synced as one 64-bit sequence number. |
||
| 10 | |||
| 11 | The Name LSA sequence number is represented by a 24-bit value. |
||
| 12 | |||
| 13 | The Adjacency LSA and Coordinate LSA sequence numbers are represented by 20-bit values. |
||
| 14 | |||
| 15 | The sequence numbers are combined as follows: |
||
| 16 | |||
| 17 | Combined sequence number = (Name LSA SeqNo << 40) | (Coordinate LSA SeqNo << 20) | (Adjacency LSA SeqNo) |
