Function Documentation

int default_routing	(	struct msu_type *	type,
		struct local_msu *	sender,
		struct msu_msg *	msg,
		struct msu_endpoint *	output
	)

The defualt routing strategy, using the key of the MSU message to route to a pre-defined endpoint.

This function can be used as-is as an entry in the msu_type struct.

Parameters

type	The MSU type to receive the message
sender	The MSU sending the message
msg	The message to be sent
output	Output parameter, set to the desired msu endpoint

Returns

0 on success, -1 on error

Definition at line 30 of file routing_strategies.c.

int route_to_id	(	struct msu_type *	type,
		struct local_msu *	sender,
		int	msu_id,
		struct msu_endpoint *	output
	)

Chooses the MSU with the given ID.

This function must be wrapped in another function to choose the appropriate ID if it is to be used in the msu_type struct.

Parameters

type	The MSU type to receive the message
sender	The MSU sending the message
msg	The message to be sent
output	Output parameter, set to the desired MSU endpoint

Returns

0 on success, -1 on error

Definition at line 61 of file routing_strategies.c.

int route_to_origin_runtime	(	struct msu_type *	type,
		struct local_msu *	sender,
		struct msu_msg *	msg,
		struct msu_endpoint *	output
	)

Routes an MSU message to the runtime on which the message originated.

This function can be used as-is as an entry in the msu_type struct.

Parameters

type	The MSU type receiving the message
sender	The MSU sending the message
msg	The message to be sent
output	Output parameter, set to the desired MSU endpoint

Returns

0 on success, -1 on error

Definition at line 76 of file routing_strategies.c.

int shortest_queue_route	(	struct msu_type *	type,
		struct local_msu *	sender,
		struct msu_msg *	msg,
		struct msu_endpoint *	output
	)

Chooses the local MSU with the shortest queue.

This function can be used as-is as an entry in the msu_type struct

Parameters

type	The MSU type to receive the message
sender	The MSU sending the message
msg	The message to be sent
output	Output parameter, set to the desired MSU endpoint

Returns

0 on success, -1 on error
