Flow Control

__congestion_parameters

this struct contains all relevant congestion control parameters for one PATH to the destination/association peer endpoint

flowcontrol_struct

fc_new_flowcontrol

Creates new instance of flowcontrol module and returns pointer to it TODO : should parameter be unsigned short ?

fc_restart

this function stops all currently running timers, and may be called when the shutdown is imminent

fc_delete_flowcontrol

Deletes data occupied by a flow_control data structure

fc_sort_tsn

helper function for sorting list of chunks in tsn order

fc_debug_cparams

function to print debug data (flow control parameters of all paths)

fc_shutdown

this function should be called to signal to flowcontrol, that our ULP has initiated a shutdown procedure.

fc_stop_timers

this function stops all currently running timers of the flowcontrol module and may be called when the shutdown is imminent

fc_timer_cb_reduce_cwnd

timer controlled callback function, that reduces cwnd, if data is not sent within a certain time.

fc_select_destination

function that selects destination index for data chunks when they are sent, or possibly new address when they are retransmitted.

fc_timer_cb_t3_timeout

timer controlled callback function, called when T3 timer expires and data must be retransmitted This timer also adjusts the slow start threshold and cwnd values As all timer callbacks, it takes three arguments, the timerID, and two pointers to relevant data

fc_update_chunk_data

function increases chunk's number of transmissions, stores used destination, updates counts per addresses

fc_check_for_txmit

function that checks whether we may transmit data that is currently in the send queue.

fc_do_timerbased_rtxmit

This function does the retransmission algorithm, after T3 timeout.

fc_send_data_chunk

Function called by stream engine to enqueue data chunks in the flowcontrol module.

fc_do_retransmission

function called by Reliable Transfer, when it requests retransmission in SDL diagram this signal is called (Req_RTX, RetransChunks)

fc_sack_info

function called by Reliable Transfer, after it has got a SACK chunk in SDL diagram this signal is called SACK_Info

fc_readNumberOfQueuedChunks

function returns number of chunks, that are waiting in the transmission queue These have been submitted from the upper layer, but not yet been sent !

fc_readCWND

Function returns cwnd value of a certain path.

fc_readCWND2

Function returns cwnd2 value of a certain path.

fc_readSsthresh

Function returns ssthresh value of a certain path.

fc_readMTU

Function returns mtu value of a certain path.

fc_readPBA

Function returns the partial bytes acked value of a certain path.

fc_readOutstandingBytesPerAddress

Function returns the outstanding byte count value of a certain path.

fc_readOutstandingBytes

Function returns the outstanding byte count value of this association.
