NAME

SimpleTCPRetransmitter — Click element; Retransmit TCP packets for the ctx subsystem

SYNOPSIS

SimpleTCPRetransmitter([INITIALBUFFERSIZE])

Ports: 2 inputs, 1 output
Processing: push

DESCRIPTION

TCPRetransmitter to use with TCPIn. Keeps reference of packets pushed on port 0 in the middleclick sractchpad until the ack is received on the other side. If a packet is sent on port 1, it will retransmit the packet kept in memory matching the sequence number.

This elements therfore allow to protect against sequence overwriting attacks but completely lets both sides manage the retransmission and timings. If you don't care, then simply push the retransmissions directly, without this element (eg fine for a NAT, LB, ... packet besed fct).
