Detailed Description

Structure to hold the information about a TCP segment.

Field Documentation

◆ ulSequenceNumber

uint32_t TCPSegment_t::ulSequenceNumber

The sequence number of the first byte in this packet

◆ lMaxLength

int32_t TCPSegment_t::lMaxLength

Maximum space, number of bytes which can be stored in this segment

◆ lDataLength

int32_t TCPSegment_t::lDataLength

Actual number of bytes

◆ lStreamPos

int32_t TCPSegment_t::lStreamPos

reference to the [t|r]xStream of the socket

◆ xTransmitTimer

TCPTimer_t TCPSegment_t::xTransmitTimer

saves a timestamp at the moment this segment gets transmitted (TX only)

◆ ucTransmitCount

uint32_t TCPSegment_t::ucTransmitCount

Number of times the segment has been transmitted, used to calculate the RTT

◆ ucDupAckCount

uint32_t TCPSegment_t::ucDupAckCount

Counts the number of times that a higher segment was ACK'd. After 3 times a Fast Retransmission takes place

◆ bOutstanding

uint32_t TCPSegment_t::bOutstanding

It the peer's turn, we're just waiting for an ACK

◆ bAcked

uint32_t TCPSegment_t::bAcked

This segment has been acknowledged

◆ bIsForRx

uint32_t TCPSegment_t::bIsForRx

pdTRUE if segment is used for reception

◆

union { ... } TCPSegment_t::u

Use a union to store the 32-bit flag field and the breakdown in the same location.

◆ xQueueItem

struct xLIST_ITEM TCPSegment_t::xQueueItem

TX only: segments can be linked in one of three queues: xPriorityQueue, xTxQueue, and xWaitQueue

◆ xSegmentItem

struct xLIST_ITEM TCPSegment_t::xSegmentItem

With this item the segment can be connected to a list, depending on who is owning it
