I like to think of the transport layer as the layer of the OSI Model that enables more interesting traffic. While we network engineers may love a lot of the simpler uses of the IP protocol and ...

A top-down exploration of networking using the 5-layer model and the TCP/IP stack. HTTP, FTP, DNS, BSD Sockets, concurrent servers, checksums, reliable transport with stop-and-wait, go-back-n, ...

The two most common transport layer protocols are the transmission control protocol (TCP) and the user datagram protocol (UDP). One of the main differences between the two protocols is reliability.

Never has the hunger for bandwidth been as high as it is today. To meet that demand, Bell Labs, the industrial research arm of Alcatel-Lucent, has been studying how high-end networks use converged IP ...

Simply put, computer networking is the study of how computers can be linked to share data. The concept of connecting computers dates back to the 1960s, when the Department of Defense led the first ...

According to the OSI Model, the session layer is where connections are established, managed, and torn down. For connection-oriented network protocols, understanding how the session layer works, and ...

Work in computer systems covers the design and implementation of computer hardware and software, including architecture, operating systems, programming languages, security and networking.
