Created a Readme & basic architecture of the program along with:
| Function | Description | Cho | Elvis | Hao | Jacob |
|---|---|---|---|---|---|
Server_State Class |
Contains the server's information including timer, id, ip, port, routing table, network topology, packets, etc | ☒ | ☒ | ☒ | ☒ |
get_ip |
used to get this server's public ip. | ☐ | ☒ | ☐ | ☐ |
get_port |
used to find the port of a given socket. (unused) | ☐ | ☒ | ☐ | ☐ |
find_id |
used to find the id of the given tuple, (ip:str, port:int), if it is adefined server, otherwise returns None. |
☐ | ☒ | ☐ | ☐ |
chkInf |
handles 'Infinity' cost when cost is used for calculation | ☒ | ☐ | ☐ | ☐ |
print_commands |
print supported commands. | ☐ | ☒ | ☐ | ☐ |
per_update |
Handling Timer for periodic message exchange | ☐ | ☒ | ☐ | ☐ |
main |
contains the runtime loop, sets up the event loop using a selector. | ☒ | ☒ | ☐ | ☐ |
menu |
called when input is recived. | ☒ | ☒ | ☒ | ☒ |
display |
display current routing table of the server. | ☒ | ☐ | ☐ | ☐ |
server |
Initial server function to get topology filename and updating time interval value. | ☒ | ☒ | ☐ | ☐ |
readTopFile |
Read topology file to establish topology and initial routing table. | ☒ | ☒ | ☐ | ☐ |
createRouteTable |
create initial routing table using topology file. | ☒ | ☒ | ☐ | ☐ |
init_listr |
used to create the listening socket. | ☐ | ☒ | ☐ | ☐ |
Update |
The link cost between two servers | ☒ | ☐ | ☐ | ☐ |
step |
Using 'send_message' function, send routing update to neighbors right away and reset periodic timer | ☒ | ☐ | ☐ | ☐ |
bellmanford |
Calculates new routing table based on the new Distance Vector Received | ☒ | ☐ | ☐ | ☒ |
recv_message |
called when a connection in the selection has something to read. | ☒ | ☒ | ☐ | ☐ |
handle_connection |
called when a connection is attempting to connect through the listening socket. | ☐ | ☒ | ☐ | ☐ |
send_message |
send routing update message in JSON format to neighbors | ☒ | ☒ | ☐ | ☐ |
formMessage |
Create routing update message to be sent out to neighbors | ☒ | ☒ | ☐ | ☐ |
packets |
Display number of distance vector (packets) this server has received sinc ethe last invocation of this information. | ☒ | ☐ | ☐ | ☒ |
disable |
Disable the link to a given server. Doing this "closes" the connection to a given server with server-ID | ☒ | ☐ | ☒ | ☐ |
crash |
Close all connections. This is to simulate server crashes. Close all connections on all links. | ☐ | ☐ | ☒ | ☒ |
send_message_crash |
send crash messages to all neighbors to alert | ☐ | ☐ | ☒ | ☐ |
eliminateCrashServer |
When a server is crashed, it eliminates the server from it's routing table and topology | ☐ | ☐ | ☒ | ☐ |
clean_up |
called when the server exits, closes selector and all sockets. | ☐ | ☒ | ☐ | ☐ |
