link-state simulation in go

for final project of computer-network course in SBU university (spring 2021) we implemented a Link-state simulation in go.

you can read full description in todo.pdf

brief description

• there is just one manager with all data's (in yaml files)
• it launch some router processes and the connect to them with tcp
• router processes transfer their connectivity table so all of them get whole network information
• manager command routers to transfer packets, so the routing will be tested.

run

• in order to run, you should run manager executable
• but before that, router should be compiled
• there is a shell script responsible for compiling and running both

configs

• manager read configs from Yaml files. there are exists in manager folder. fill free to change them
• there should be just one connection component (all routers should connect to each other indirectly)
• packets will send in order.

logs

• manager will print its own logs to stderr

• routers write logs to separate log files (with name of their indices)

• if a router fail before initializing the log file, it will send that failing log to manager (manager is watching router processes stderr files)

• run.sh will print all log files in order with one line between them, so you don't need to do anything in order to see logs.
