Most protocols use layered architectures to some degree, layers that you can manipulate to achieve your optimal design. Optimizing the placement of these layers, you can achieve efficient code ...

“This is not an easy subject to talk about. There are so many protocols, and terms have evolved—even the way the word ‘Ethernet’ has been used,” states John Ditter, input/output product specialist ...

Getting started on designing a network is a task of formidable proportions, but all the more so if you are looking to build a secure IT network. Often, IT system administrators are not fully familiar ...

What is a network protocol? Most textbook writers state something like this: A network protocol is a set of guidelines or standards for the operation of network devices, the methods of operation, and ...

The increase in network-connected devices the past years has been something of a dual-edged sword. While on one hand it’s really nice to have an easy and straight-forward method to have devices talk ...

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, ...

The iWARP protocol is the IETF standard for RDMA over Ethernet, and offers an alternative to specialized fabrics such as InfiniBand. The challenge for data center operators selecting a high ...
