The Echo Protocol is a service in the Internet Protocol Suite defined in RFC 862. This is a list of Internet socket port numbers used by protocols of the Transport Layer of the Internet Protocol Suite for the establishment of host-to-host communications. It seems that the IANA frequenly assigned both TCP and UDP ports to a protocol even if it only actually used one or the other. Port though often changed during installation. In programming APIs (not in communication between hosts), requests a system-allocated (dynamic) port. These packets are treated similarly, as they’re forwarded from your computer to intermediary routers and on to the destination. NBT has long been the central protocol used to interconnect Microsoft Windows machines. Protocol. IMAP version3 is the second of the main protocols used to retrieve mail from a server. The server sends back an identical copy of the data it received. User Datagram Protocol. Some of the services that are applicable to both TCP and UDP protocols are as follows: 1. I am talking about those used in access lists, like "www" for port 80 and "smtp" for port 25, e.g. The main difference between the two protocols is that TCP uses a connection-oriented transport, while UDP uses a … The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) are used to transmit network data to and from server and client applications. Despite this port being assigned by IANA, the service is meant to work on, Xerox Network Systems (XNS) Mail. Replacing protocol in TCP/IP is not easy. The service provided by UDP is sometimes referred to as "unreliable" since the protocol provides no guarantees for delivery and no protection from duplication.
