The Transmission Control Protocol, or TCP as we will refer to it from now on, is one of the most important and well-known protocols in the world on networks today. Used in every type of network world-wide, it enables millions of data transmissions to reach their destination and works as a bridge, connecting hosts with one another and allowing them to use various programs in order to exchange data. The Need For Reliable Delivery TCP is defined by RFC 793 and was introduced to the world towards the end of 1981. The motivation behind creating such a protocol was the fact that back in the early 80s, computer communication systems were playing a very important role for the military, education and normal office environments. As such, there was the need to create a mechanism that would be robust, reliable and complete data transmission on various mediums without great losses.

TCP was designed to be able to deliver all of the above, and so it was adopted promptly by the rest of the world. Learning Labs CCNA & CCNP Labs.

Wiki:vpcs [Who Is Wiki] The VPCS can simulate up to 9 PCs. You can ping/traceroute them, or ping/traceroute the other hosts/routers from the virtual PCs when you study the Cisco routers in the Dynamips. VPCS is not the traditional PC, it is just a program running on the Linux or Windows, and only few network commands can be used in it. But VPCS can give you a big hand when you study the Cisco devices in the Dynamips. VPCS can replace the routers or VMware boxes which are used as PCs in the Dynamips network. Try VPCS, it can save your CPU/Memory. Now, VPCS can be run in udp or ether mode.
