Special Forums UNIX and Linux Applications Information on forwarding queue occupation in a Linux router Post 303039953 by Neo on Friday 18th of October 2019 10:51:16 PM
TCP is a "connection-oriented" "end-to-end" client-server protocol.

This means that parameters related to TCP sockets, buffers, lengths, fragments, etc. effect the end-to-end connection and are controlled by the end-to-end TCP connection, not the intermediate routing devices and intermediate hosts.

Difficulty: Medium
All programming languages have automatic garbage collection that monitors the dynamically allocated pieces of memory and determine if any variable in the program still references it. If the memory is no longer referenced, it is 'garbage' and becomes eligible to be 'collected'.
True or False?

socket.h - Network addresses and sockets related classes. SYNOPSIS
#include <cc++/address.h> Classes class ost::Socket The Socket is used as the base for all Internet protocol services under Common C++. class ost::DCCPSocket DCCP sockets are used for stream based connected sessions between two sockets. class ost::UDPSocket UDP sockets implement the TCP SOCK_DGRAM UDP protocol. class ost::UDPBroadcast Representing a UDP socket used for subnet broadcasts, this class provides an alternate binding and setPeer() capability for UDP sockets. class ost::UDPTransmit Representing half of a two-way UDP connection, the UDP transmitter can broadcast data to another selected peer host or to an entire subnet. class ost::UDPReceive Representing half of a two-way UDP connection, the UDP receiver can receive data from another peer host or subnet. class ost::UDPDuplex UDP duplex connections impliment a bi-directional point-to-point UDP session between two peer hosts. class ost::TCPSocket TCP sockets are used for stream based connected sessions between two sockets. class ost::TCPV6Socket TCPV6 sockets are used for stream based connected sessions between two ipv6 sockets. class ost::TCPStream TCP streams are used to represent TCP client connections to a server by TCP protocol servers for accepting client connections. class ost::TCPSession The TCP session is used to primarily to represent a client connection that can be managed on a separate thread. class ost::SimpleTCPStream Simple TCP Stream, to be used with Common C++ Library.
