TCP – TRANSMISSION CONTROL PROTOCOL

Posted on | by Telecom and Networking | Leave a Comment on TCP – TRANSMISSION CONTROL PROTOCOL

TRANSMISSION CONTROL PROTOCOL (TCP) Originally, Vinton Cerf and Robert Kahn designed TCP to provide reliable data transmission between remote hosts communicating over a packet-switched network. Before the invention of TCP, data transmission over packet-switched network infrastructures proved somewhat unreliable. The quality of delivery (or lack of reliability), different media types, and the potential for congestion […]

Service Location Protocol (SLP) The Service Location Protocol (SLP) provides a scalable framework for the discovery and selection of network services.  Using this protocol, computers using the Internet no longer need so much static configuration of network services for network-based applications. This is especially important as computers become more portable, and users less tolerant or […]
