- Unfortunetaly, on L2 all messages are sending to all members of the cluster.
- unicast: dst_node_id == node_id
- broadcast: dst_node_id == NOID
- session example of two nodes (A and B):
- "A" appears (getting node_id):
- A -> hello (serial: 0; src: NOID ; dst: NOID; name: A) | cluster_init()
- A -> register (serial: 1; src: 0 ; dst: NOID; name: A) |
- Trying to sync with somebody:
- A -> updtree (serial: 2; src: 0 ; dst: NOID; [A modtree])
- "B" appears (getting node_id):
- B -> hello (serial: 0; src: NOID ; dst: NOID; name: B) | cluster_init()
- A -> welcome (serial: 3; src: 0 ; dst: NOID; my_name: A; to_name: B)
- B -> register (serial: 1; src: 1 : dst: NOID; name: B) |
- A -> ack (serial: 4; src: 0 ; dst: 1; ack_serial: 1)
- Initial syncing A <-> B:
- B -> updtree (serial: 2; src: 1 ; dst: NOID; [B modtree])
- A -> updtree (serial: 5; src: 0 ; dst: NOID; [A modtree])
- A -> lock (serial: 6: src: 0 ; dst: NOID; [paths list])
- B -> ack (serial: 2; src: 1 ; dst: 0; ack_serial: 6)
- B -> lock (serial: 3: src: 1 ; dst: NOID; [paths list])
- A -> ack (serial: 7; src: 0 ; dst: 1; ack_serial: 3)
- A -> unlockall (serial: 8: src: 0 ; dst: NOID)
- B -> ack (serial: 4; src: 1 ; dst: 0; ack_serial: 8)
- B -> unlockall (serial: 5: src: 1 ; dst: NOID)
- A -> ack (serial: 9; src: 0 ; dst: 1; ack_serial: 5)
- Just syncing A -> B:
- A -> lock (serial: 10: src: 0 ; dst: NOID; [paths list])
- B -> ack (serial: 6; src: 1 ; dst: 0; ack_serial: 10)
- A -> unlockall (serial: 11: src: 0 ; dst: NOID)
- B -> ack (serial: 7; src: 1 ; dst: 0; ack_serial: 11)
- "A" disappers (shutdown)
- "A" appears (registering with old node_id)
- A -> hello (serial: 0; src: NOID ; dst: NOID; name: A)
- B -> welcome (serial: 4; src: 1 ; dst: 0; my_name: B; to_name: A)
- A -> register (serial: 1; src: 0 ; dst: NOID; name: A)
- B -> ack (serial: 5; src: 1 ; dst: 0; ack_serial: 1)
- [...]
