每个node是否按顺序编号？如果是的话，它需要先向某个节点询问一共有多少个节点，它是多少号，这可能会引起分歧？还是说node自己起id，然后进行hash

Code Structure

• design/design.md: illustrating psudocode
• Config.py: saving the universal parameter for the system
• hash_ring.py: provide the hash consistant algorithm
• network_layer.py: define the 'Node' data structure, handling its behaviours
• data_layer.py: define the 'Data' data structure, handling its behaviours
• operation.py: list all the behaviour the node will be acting, act as state transition trigger in the state machine
• main.py: currently no 'main.py', it's now in 'operation.py' for convinience

How to run

Start Node

• For the first node:
  • python operation.py start_root_node
• For other node:
  • python operation.py start_node ID IP PORT

Store File

• First start the client
  • python client.py
  • check node_state: node_table
  • check data_state: data_table
  • store data: store FILE_PATH
  • download data: first data_table to know it's sequence, then download SEQUENCE
