Constructor & Destructor Documentation

LoadBalancer()

LoadBalancer::LoadBalancer	(	int	num_servers,
		int	time_to_run,
		std::ostream &	output_stream )

Constructs a LoadBalancer with a given number of servers and run time.

Constructs a LoadBalancer with a given number of servers and run time. Initializes the request queue and creates the initial set of servers.

Parameters

num_servers	Number of web servers to start with.
time_to_run	Number of cycles to run the load balancer.
output_stream	Output stream for logging.

Member Function Documentation

add_request()

void LoadBalancer::add_request ( const Request & req )

inline

Adds a request to the request queue.

Parameters

req	The request to add.

generate_random_request()

Request LoadBalancer::generate_random_request

(

)

Generates a random request with random IPs and duration.

Returns

A randomly generated Request object.

handle_requests()

void LoadBalancer::handle_requests

(

)

Main loop for handling requests and managing servers. Continues until the specified run time is reached.

Main loop for handling requests and managing servers. Assigns requests to idle servers, scales server pool, and simulates new requests.

is_finished()

bool LoadBalancer::is_finished ( )

inline

Checks if the load balancer has finished running.

Returns

True if the elapsed time is greater than or equal to the run time.
