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, ...

There are a number of emerging and proposed standard protocols focused on optimizing the support that data center Ethernet LANs provide for server virtualization. Several of these protocols are aimed ...

A group of fields in a network packet that describes its content, all required destination addresses to reach its target, and all source information necessary to allow a response to come back. See ...

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 ...

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), ...

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 ...

The field of packet classification is pivotal to modern network operations, underpinning the ability to manage data traffic efficiently and securely. This discipline involves algorithms and ...

A computer network as we usually visualize it involves various cables (Ethernet, fiber optic, coaxial) connecting to appliances like routers and switches, which direct data packets where they need to ...
