I had an assignment at university that dealt with the size of a message after being sent through two different types of networks with different packet sizes and network headers. That's all we were ...

A typical User Datagram Protocol/Internet Protocol (UDP/IP) header contains 20 bytes of IP header and eight bytes of UDP header. While UDP headers contain source and destination UDP port addresses, ...

Voice over IP (VoIP) is the descriptor for the technology used to carry digitised voice over an IP data network. VoIP requires two classes of protocols: a signaling protocol such as SIP, H.323 or MGCP ...

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 ...

If you are using Internet or almost any computer network you will likely using IPv4 packets. IPv4 uses 32-bit source and destination address fields. We are actually running out of addresses but have ...

IPsec is a suite of protocols that are used to secure internet communications—in fact, the name itself is an abbreviation for Internet Protocol Security. IPsec was first codified in the ’90s, spurred ...

Computer engineers learn early on that a core set of protocols are critical to networks. Some of the most important protocols include Internet Protocol (IP), Transaction Control Protocol (TCP), ...

Researchers present a system for testing new traffic management protocols that requires no alteration to network hardware but still works at realistic speeds -- 20 times as fast as networks of ...

There is a core set of protocols critical to the operation of computer networks. Some of the most important protocols include IP, Transmission Control Protocol (TCP), Address Resolution Protocol (ARP) ...
