Considerations of Change: An Intro to Networking in IoT

One of the major consequences of Moore’s Law for silicon is that pretty much any device now can have a reasonable level of computing power and internet connectivity. Because of this, the number of internet enabled devices is increasing, thus causing a huge influx of IoT traffic; it is predicted that WAN bandwidth will need to be increased.

When one considers the types of data that will be generated, it becomes clear that they both present challenges. George Crump, an analyst with Storage Switzerland points this out7. “First, there is large-file data, such as images and videos captured from smartphones and other devices. This data type is typically accessed sequentially,” explains Crump. “The second data type is very small, for example, log-file data captured from sensors. These sensors, while small in size, can create billions of files that must be accessed randomly.”

From this, it is clear that data centers will need to handle both types of data, and the storage and processing requirements that come with them.

For decades, the network was considered to be the plumbing of a company’s IT solutions, and was considered a somewhat dumber element of the design. With the advent of IoT, it is clear that the networking element of the IoT ecosystem is slightly lagging behind, which is a concern as IoT is very much a network centric technology, and in essence makes the web by which the sensors communicate to the host and to each other. There are a number of ways for these devices to be networked. Some devices can be directly connected to the internet utilizing standard Ethernet or Wifi, which are TCP/IP based. There are other wireless technologies, some of which are dependent on TCP/IP, but all require some sort of intelligent gateway to convert their network into standard Ethernet or Wifi. These include, but are not limited to, Zig Bee, Z-Wave, Bluetooth, and Cellular.

Evolution towards IPv6 

Due to the advancement of object gateways, the first two stages of the IoT roadmap will sit on current infrastructure and protocols. Once the volume of devices and data increases and true IoT is in motion, the IPv6 protocol will be required, which offers unlimited IP addresses.

The main challenge that IPv6 looks to overcome is the large packet size when we consider standard IP protocols. For IPv6, the packet size is reduced by making a number of changes to the release of the 6LoWPAN standard, namely RFC 4944. Changes included the compression of IP headers and the introduction of a fragmentation mechanism that enabled reassembly of IP packets that did not fit the IEEE 802 packet. Lastly, routing protocols for lossy, low power networks were required. New protocols were developed by the Internet Engineering Task Force (IETF) that provided basic routing in low power lossy networks.

In my next blog post, i will continue to write about network enablement requirements, talking about why IoT needs “Software Defined Networking” (SDN)

DENIS CANTY IS EXCITED TO BEGIN IN JULY 2017 WITH MCKESSON, A FORTUNE 5 COMPANY – AS THEIR SENIOR DIRECTOR OF CYBER SOFTWARE ENGINEERING IN CORK. HIS LAST ROLE (TO JUNE 2017) WAS AS THE LEAD TECHNOLOGIST FOR IOT WITH JOHNSON CONTROLS INNOVATION GROUP BASED IN CORK, IRELAND. THAT ROLE MEANT COLLABORATING EXTENSIVELY BETWEEN HIS TECHNICAL AND SALES TEAMS TO DRIVE FURTHER COMMERCIALISATION OPPORTUNITY THROUGH TECHNOLOGY (BOTH OUR OWN AND PARTNERS/STARTUPS) INTO OUR SALES CHANNELS, SPECIFICALLY LOOKING AT THE EMERGING SMART BUILDING MARKET. THE PROJECTS INCLUDE OUR EXISTING TECHNOLOGIES – BUILDING SECURITY, RETAIL, HVAC AND BUILDING ENERGY – AND EMERGING TECHNOLOGIES SUCH AS IOT, AR AND MACHINE LEARNING. A KEY COMPONENT WAS TAKING KEY INPUT FROM NUMEROUS STAKEHOLDERS AND PROCESSES TO DELIVER ROI FOR CUSTOMERS AND PARTNERS. HE THEN LED THE TEAM TO BUILD AND DEPLOY THE SOLUTIONS IN AN LEAN AGILE MANNER. DENIS SPOKE ON THE NATIONAL AND INTERNATIONAL CIRCUIT FOR JOHNSON CONTROLS AT NUMEROUS TECHNOLOGY CONFERENCES. HIS LEADERSHIP STYLE IS LEADERSHIP THROUGH TRUST AND DELIVERY, AND I TAKE RESPONSIBILITY FOR MY TEAM, COMPASSION AND HUMILITY ARE ALSO IMPORTANT AS A LEADER IN MY OPINION. I LIKE TO BUILD A BALANCED CULTURE, WITH THE PEOPLES PERSONALITIES IMPORTANT INPUTS INTO THAT. DENIS HAS A DEGREE IN ELECTRONIC ENGINEERING (2H) FROM CORK INSTITUTE OF TECHNOLOGY, A MASTERS IN MICROELECTRONIC CHIP DESIGN (1H) FROM UNIVERSITY COLLEGE CORK AND A MASTERS IN COMPUTER SCIENCE (1H) FROM DUBLIN CITY UNIVERSITY. PRIOR TO JOHNSON CONTROLS, DENIS HELD A POSITION OF PRINCIPAL DATA ARCHITECT AND DEVELOPMENT MANAGER WITH EMC FROM 2010 TO 2015, SPENDING 2011 IN SILICON VALLEY. HE LED A TEAM FOCUSED AT REDUCING AND CONSUMING NINE TEST AUTOMATION PLATFORMS FROM EXTERNAL MANUFACTURERS TO ONE EMC CLOUD HOSTED PLATFORM. HE ALSO WORKED ON A NUMBER OF WORKFLOW AUTOMATION SOFTWARE REPLACING TEDIOUS MANUAL EXTRACT, SEARCH AND REPORT COMPILATION THAT RESULTED IN EFFICIENCY GAIN (WRITTEN IN PYTHON). I ALSO BUILT PREDICTIVE ANALYTICS APPLICATION IN MANUFACTURING AND DATA SCIENCE MODELS FOR THE CUSTOMER VERTICAL WITH THE CTO OFFICE. DENIS BROUGHT MICROSERVICES BASED DESIGN ALONG WITH DISTRIBUTED STORAGE AND PROCESSING TO THE GROUP, CHANGING THE DEVELOPMENT CULTURE IN THE PROCESS. DENIS WAS ALSO A MEMBER OF EMC’S GLOBAL INNOVATION COUNCIL AND AS AN AMBASSADOR WITH THEIR OFFICE OF THE CTO, LEADING THEIR CUSTOMER INSIGHT SOFTWARE DEVELOPMENT. DENIS WON TWO GLOBAL INNOVATION AWARDS IN HIS TIME WITH EMC, IN THE AREAS OF SUSTAINABILITY AND E-SERVICES, AND HAS A PATENT IN INTELLIGENT POWER MANAGEMENT ON STORAGE ARCHITECTURE. HE ALSO WORKED PREVIOUSLY FOR ALPS AUTOMOTIVE DIVISION FROM 2005-2010, IN A VARIETY OF ROLES, INCLUDING AS THE LEAD COMPUTER VISION ENGINEER, AND THE LEAD TECHNOLOGIST ON EUROPEAN RESEARCH PROJECTS IN THE AREAS OF IN-VEHICLE DISTRACTION MONITORING AND SMART HOME DEVICES. DENIS ALSO SPENT TIME CONSULTING IN THE START-UP WORLD, SUCH AS A HEALTHCARE INFORMATICS CONSULTANT WITH ACE HEALTH, LEADING THE DEVELOPMENT FOR AN APPLICATION WHICH HELPS HEALTHCARE SERVICE PROVIDERS ACHIEVE BETTER PATIENT OUTCOMES AND CUT COSTS THROUGH A REGULATOR-APPROVED PREDICTIVE ANALYTICS PLATFORM IN THE DUTCH AND US MARKETS. HE ALSO HAD HELPED NUMEROUS STARTUPS ON BUILDING THEIR TECHNOLOGY ROADMAP TO ALIGN WITH DEFINED TARGET MARKETS AND CUSTOMER BASES.
