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.

SDN/NFV (Software Defined Networking, Network Functions Virtualization): Networking Game Changers?
The terms SDN (Software Defined Networks) and NFV (Network Functions Virtualization) have acquired magical connotations for those who work with networks but are not technical, raising many expectations. Are SDN and NFV really such a game changer for networking? SDN and NFV are among the half dozen or so technologies seeking to address the issues that trouble contemporary networks. The other major technologies in the mix include GMPLS, ASON, high-speed Ethernet, NGN, and OTN, with a good deal of overlap between the various solutions that have been proposed.

Distributed Computing for IoT: Data Management in a Fog Computing Environment
Mobile cellular operators are making plans for Mobile Edge Computing (MEC), which enables Cloud computing capabilities and an IT service environment at the edge of the cellular network. It is a concept developed by ETSI (European Telecommunications Standards Institute) that aims to bring computational power into Mobile RAN (radio access network) to promote virtualization of software at the radio edge. MEC brings virtualized applications much closer to mobile users ensuring network flexibility, economy and scalability for improved user experience.

The IoT and the Serious Security Risks It Poses
Introduction The Internet of Things (IOT) refers to the increasingly networked world we now inhabit, in which more and more “smart” devices use Internet to interact with other devices, servers, or with various users. It is not a new type of Internet, but an evolutionary development that shows how incremental technology growth can lead to…

The Internet of Things (IoT) Revolution: Are You Ready?
Nearly every industry vertical stands to be transformed by the coming IoT revolution. The IoT technology is creating enormous opportunities for new services as well as more efficient delivery of existing services. The rapid pace at which this technology is evolving is also giving rise to major privacy/security risks for individuals, institutions, and public infrastructure — creating new vulnerabilities and giving rise to not-as-yet-thought-of attack modalities, including those of remotely engineered death and destruction.

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.

Communications networks are rapidly evolving into policy-based, packet-oriented networks designed to provide a particular quality-of-services (QoS) for subscribers while reducing the costs associated with capital expansions, network operations, and management. If you are involved with telecommunications planning, engineering, deployment, strategy, marketing, or services creation, it is critical that you understand the technology and business implications of IMS.

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
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.
