Ethernet is a frame-based data communication technology that employs variable-sized frames to carry a data payload. This contrasts with long-haul Optical Transport Networks (OTN) that use fixed-sized ...

Ethernet has become the primary network protocol of choice for the required server-to-server communication in hyperscale data centers, as it allows hyperscalers to ...

Wired data connections will never be entirely replaced by wireless ones, but the Ethernet protocol still has some design constraints that limit the performance of certain data transfers. One way to ...

Traditional approaches to data center networking cannot satisfy the scale, bandwidth, latency and cost points required for evolving data center software architectures. Fibre Channel and InfiniBand ...

Recently, the Internet Engineering Task Force (IETF) completed its work on an iSCSI specification that leaves the industry with a standard for building storage networks based on Ethernet/TCP/IP ...

Cisco’s FabricPath data center Ethernet technology is designed to combine traditional, Spanning Tree-based Ethernet with a next-generation architecture that uses a link-state protocol to allow for ...

We met Mr. Murphy, of “What can go wrong, will” infamy, in the introduction to failure modes and the discussion of failure modes at the foundation levels. Now we will learn his tricks on shared media ...

Ethernet is the major local-area network (LAN) in which we connect our computers, routers, and printers. It has taken an important role in the industrial engineering world, having become the ...

The differences between physical and data-link layers in Ethernet. Key factors in selecting an industrial PHY. The physical layer specifies the types of electrical signals, signaling rates, media and ...

Early concerns about Ethernet as an automation network included its lack of real-time capabilities. But several new approaches seek to overcome this limitation. One company making waves in the ...
