Detailed Description

Implements congestion control hooks for control.c.

Author:

Ivan Beschastnikh

This file contains functions that are called from control.c whenever cc needs to be done or queried for advice. For now this file is included in control.c and all functions are inlined for efficiency.

• 05/28/06 ivan Moved to use btree instead of minhist structure for delay tracking
• 03/25/06 ivan Joined with ccontrol.h, functions renamed, delay-based cc functions created.
• 03/20-24/06 ivan Lots of work and everything is revamped to do delay based CC
• 02/19/06 ivan Added minhist addition of delay values
• 02/18/06 ivan Created

Function Documentation

int CC_Can_Send_Data	(	size_t	data_size,
		vfer_sock *	sock
	)			[inline]

Determines if a data packet of specific size can be sent at this time on a socket, uses byte accounting.

Parameters:

	data_size	data size that control.c would like to send as a data packet
	sock	socket whose cc we are dealing with

Returns:

0 if CC doesn't allow for sending of data_size bytes

1 if CC does allow for sending of data_size bytes

Definition at line 65 of file vfer_ccontrol.c.

void CC_Recvd_Ack	(	packet *	p,
		vfer_sock *	sock
	)

Takes appropriate CC action upon receiving a cc ack packet. Currently implements a delay based CC.

Parameters:

	p	cc ack packet
	sock	socket whose cc we are dealing with

Definition at line 134 of file vfer_ccontrol.c.

void CC_Recvd_Close	(	packet *	p,
		vfer_sock *	sock
	)

Takes appropriate CC action upon receiving a close packet

Parameters:

	p	cc ack packet
	sock	socket whose cc we are dealing with

Definition at line 44 of file vfer_ccontrol.c.

void CC_Recvd_Data	(	packet *	p,
		vfer_sock *	sock
	)

Takes appropriate CC action upon receiving a data packet

Parameters:

	p	data packet
	sock	socket whose cc we are dealing with

Definition at line 95 of file vfer_ccontrol.c.

void CC_Sent_CtlPack	(	packet *	p,
		vfer_sock *	sock
	)

Takes appropriate CC action after having sent a control packet

Parameters:

	p	control packet
	sock	socket whose cc we are dealing with

Definition at line 32 of file vfer_ccontrol.c.

void CC_Sent_Data	(	packet *	p,
		frame_link *	frame,
		vfer_sock *	sock
	)			[inline]

Takes appropriate CC action after having sent a data packet

Parameters:

	p	data packet which was sent
	frame	frame pointer of which the data packet is carrying a fragment
	sock	socket whose cc we are dealing with

Definition at line 79 of file vfer_ccontrol.c.
