What is end-to-end communications?

The end-to-end principle is a network design method in which application-specific features are kept at communication end points. The principle was developed to address the need for reliable communications in inherently unstable environments and has long been employed in most networking models.

Which protocol provides reliable end-to-end communication?

Transmission control protocol (TCP)
1. Transmission control protocol (TCP) TCP is a transport level protocol of the Internet that provides reliable, end-to-end communication between two processes. The requesting process, often known as the client, requests services from the server process.

Why does TCP account for reliable end-to-end communications?

It is one of the most commonly used protocols within digital network communications and ensures end-to-end data delivery. TCP organizes data so that it can be transmitted between a server and a client. It guarantees the integrity of the data being communicated over a network.

Is IP addressing end-to-end?

A source device will send a packet based on an IP address. So, in short, IP addressing determines the end-to-end behavior of an IP packet. However, along each link in a path, an IP packet is encapsulated in a frame specific to the particular data link technology associated with that link, such as Ethernet.

How is the end to end principle used on the Internet?

On the internet, IP is used for nearly all communications. End-to-end acknowledgment and retransmission is the responsibility of the connection-oriented Transmission Control Protocol (TCP) which sits on top of IP. The functional split between IP and TCP exemplifies proper application of the end-to-end principle to transport protocol design.

Who is the founder of the end to end principle?

End-to-end principle. The essence of what would later be called the end-to-end principle was contained in the work of Paul Baran and Donald Davies on packet-switched networks in the 1960s. Louis Pouzin pioneered the use of the end-to-end strategy in the CYCLADES network in the 1970s.

Which is responsible for end to end retransmission?

Internet Protocol (IP) is a connectionless datagram service with no delivery guarantees. On the Internet, IP is used for nearly all communications. End-to-end acknowledgment and retransmission is the responsibility of the connection-oriented Transmission Control Protocol (TCP) which sits on top of IP.

What is the end to end principle of ARPANET?

The ARPANET was designed to provide reliable data transport between any two end points of the network – much like a simple I/O channel between a computer and a nearby peripheral device.
