h1. erlbal
erlbal is an erlang load balancer.
h2. Balancer calls:
* start_bal/0 spawns a balancer.
* stop_bal/1 takes a balancer and kills all of its servers and then kills the balancer.
* list_servers/1 takes a balancer and returns a list of the servers it balances over.
h2. Server calls:
* start_server/2 takes a balancer, a node and a function and spawns a server on the node to serve the function.
* stop_server/2 takes a balancer and a server PID and stops the server and removes it from the balancer.
h2. Request calls:
* make_request/1 takes a balancer and returns the response from the server.
* make_request/2 takes a balancer and an argument and returns the response from the server.
h2. Info
p. The balancer round robins requests between erlang processes.
When it receives a request, it forwards it on to the next server in the round robin.
The server then runs the function with the argument passed to it and returns a response to the balancer.
The balancer forwards the response back to the requestor.
p. The function arg could be anything, so you can pass multiple args in a tuple or list, etc.
