Networks function and flourish because they deliver reliable and fast communication over large distances. And while people often marvel at the speed, it's the reliability -- made possible through the ...
When working with TCP/IP, the model is simplified to four layers plus the physical layer as shown in Figure 2-4. This figure depicts the encapsulation process with protocol overhead down to Ethernet, ...
Do you remember when we used multi-protocol routing for IPX, AppleTalk, and TCP/IP running on the same network? In the 1980s and early 1990s many enterprises had multiple protocols running on the ...
Over the last several years, TCP/IP has gone from being the protocol that only geeks use, to a universal protocol that everyone uses, thanks to the widespread use of the Internet. TCP/IP has been ...
In the world of Linux networking, protocols play a crucial role in enabling seamless communication between devices. Whether you're browsing the internet, streaming videos, or troubleshooting network ...
The data transfer in a TCP/IP network is usually block-based. From a programmer’s point of view, sending data means issuing a series of “send data block” requests. On a system level, sending an ...
“Not being overcomplicated is Modbus TCP/IP’s biggest draw, not only for PLCs, but especially for PC-based applications,” said Jason Haldeman, senior product specialist for I/O and networking at ...
Transmission Control Protocol (TCP) is the basic communication protocol of the Internet as well as many private networks throughout the world. Along with User Data Protocol (UDP), TCP represents the ...
The numeric identification of the upper layer protocol that an IP packet should be sent to. The number is stored in the header that is prefixed to an IP packet. Note that the IP protocol number is not ...
In a previous article, we explained how you can use the sendfile() syscall to reduce the overhead of data transfer from a disk to a network. Now, we’re going to cover another aspect of network ...
