Optical Networking: Past and Future

Light-based methods have been used for information transmission for thousands of years. Probably the earliest method is the fires that have been used for signaling since Biblical times.Smoke signals have been used for communications for a long time, most notably by Native Americans. Lanterns hung in Boston’s Old North Church (“One if by land, and two if by sea”) figure prominently in Paul Revere’s famous midnight ride in 1775.

MRI Is to Medical Diagnosis as Wireshark Is to Network Traffic Analysis and Troubleshooting

I really enjoy watching the TV show House. Not for Hugh Laurie’s award-winning sarcasm – which I find formulaic and annoying – but, rather, to watch the diagnostic process unfold. House is truly unique because the real star of the show might turn out to be leishmaniasis or schistosomiasis rather than Brad Pitt or George Clooney. I watch the team meetings and brainstorming with great interest, the whiteboard filling with symptoms, while the team postulates the cause.

The Internet of Things: Smart Devices, M2M, WSNs, and IoT

At its most basic level, IoT just connects simple devices over the Internet or other network which could be private and/or wireless. Common examples include the ‘program-from-anywhere’ thermostats and security systems already in use. At the mid-level, IoT is an enabler of new business and technology models, not just incremental improvement of existing ones. For example, autonomous vehicles will require very high levels of communication among devices in the vehicle (e.g., LIDAR, sensors, cameras, computers) and most likely devices/sensors outside the vehicle (e.g., other vehicles, fixed cameras, servers with detailed maps). At the highest level, the interconnection of devices could lead, over time, to new technologies that will reorganize the society, much as the automobile and the Internet have. One possibility is the “Smart City”, where IoT is used not only in autonomous vehicles, but where all types of transportation are linked to provide optimized people movement. Private self-drive cars, in this scenario, would rarely be needed. This could lead to entirely different land use patterns, for example.

“When It Comes to Web 2.0 and Next Gen Communications, I’m with Tim … Pretty Much.”

Timothy Berners-Lee invented the browser and, subsequently, the World Wide Web. The impact of this browser thing of his is so profound that not only does it transform the way that everyone in the industrialized world interacts with each other, it inspired Her Royal Highness Queen Elizabeth – with but two taps of the royal sword – to transform Mr. Berners-Lee himself into Sir Timothy.

Tutorial: Voice over IP (VoIP)

VoIP, Voice over IP, stands for Voice over the Internet Protocol. In VoIP, voice calls are packetized to allow the voice traffic to “ride over” the organization’s data network. This eliminates the need for a separate voice network with its dedicated voice circuits, thereby saving resources and costs.

MPLS

Dr. Thomas Fowler

MPLS and the Evolving Telecom Landscape

By 2010 both ATM and FR were in fairly steep decline, relegated to the status of legacy technologies. MPLS usage is growing and new applications for it continue to emerge, making it the technology of choice for most large-scale networks. Nowadays the great buzzword is “cloud computing”, with different versions such as Software as a Service (SaaS—Gmail, Google maps, YouTube, Facebook), Platform as a Service (PaaS—Amazon Elastic Compute Cloud, Windows Azure, Salesforce). All of these utilize MPLS-based networks.

SDN/NFV: Enhancing Network Capacity and Functionality

SDN and NFV have been developed to help meet the challenge of increasing demand for services and user expectation of rapid provisioning and universal availability. Both rely on virtualization, the ability to make a piece of equipment look like another via the magic of software. SDN was originally developed to address the problems of large data centers, where virtualization of hardware and operating system is important. It will likely spread to other areas, including the WAN, where virtualization and the ability to dial up bandwidth and related characteristics would be extremely valuable as well. NFV is an outgrowth of SDN in many respects, concentrating on backbone networks, where the need to rapidly reconfigure resources is key.

The Internet of Things (IoT) Revolution: Are You Ready?

Powered by the expansion of connectivity fueled by IPv6, the Internet is quickly morphing from a ‘network of computers’ into a ‘network of things’, and this technology is developing at a much faster pace than other such technologies of the past. Smart phones, cars, homes, buildings, wearable computing devices, unseen but ubiquitous sensors embedded into appliances, equipment and infrastructure, and many other “things” (including living things such as cattle and wildlife) are all getting linked up into a vast and pervasive Internet of Things (IoT)! It’s a disruptive technology that — though largely invisible to consumers — will have profound impact on our everyday lives, how businesses operate, and on the world economy as a whole (multi-trillion dollars) — all in as little as five to 10 years.
