Apollo 11 Command Module (1965) had 64 kilobytes of memory operated at 0.043MHz.

An iPhone 5s has a CPU running at speeds of up to 1.3GHzand has 512MB to 1GB of memory

Cray-1 (1975) produced 80 million Floating point operations per second (FLOPS)10 years later, Cray-2 produced 1.9G FLOPS

An iPhone 5s produces 76.8 GFLOPS – nearly a thousand times more

Cray-2 used 200-kilowatt power

Computing Power

−Smaller size−More Powerful−More memory and more storage

−"Moore's law" over the history of computing, the number of transistors in a dense integrated circuit has doubled approximately every two years.

Smaller in size but larger in scale

The Internet: A brief history

− 1961: Leonard Kleinrock at MIT published the first paper on packet switching theory in July 1961.

− 1962: J.C.R. Licklider of MIT discussed his "Galactic Network" concept - a globally interconnected set of computers through which everyone could quickly access data and programs from any site.

− 1968: an RFQ was released by DARPA for the development of one of the key components, the packet switches called Interface Message Processors (IMP's).

− The RFQ was won in December 1968 by a group headed by Frank Heart at Bolt Beranek and Newman (BBN).

The Internet: A brief history

− 1970: the Network Working Group (NWG) working under S. Crocker finished the initial ARPANET Host-to-Host protocol, called the Network Control Protocol (NCP).

− 1972: Bob Kahn organized a large, very successful demonstration of the ARPANET at the International Computer Communication Conference (ICCC). − This was the first public demonstration of this new

network technology to the public.

− 1972: the first "hot" application, electronic mail, was introduced.

The old Internet timeline

TCP/IP in the early days of the Internet

− The original Cerf/Kahn paper on the Internet described one protocol, called TCP, which provided all the transport and forwarding services in the Internet.

− A 32 bit IP address was used of which the first 8 bits signified the network and the remaining 24 bits designated the host on that network.

− The assumption was that 256 networks would be sufficient for the foreseeable future…

− Obviously this was before LANs (Ethernet was under development at Xerox PARC at that time)

Expansion beyond estimation

In November 1979, a proposal was submitted to NSF to fund a consortium of eleven universities at an estimated cost of $3 million over five years. This is viewed as too costly by the NSF.

Predicting the future (in 1999)!

− 1999: “The number of hosts (locatable through DNS) will exceed 100 M, very soon!”

− A few years later in 2013, 80 “things” per second were connecting to the internet. In 2014 that number was around 100 per second, and by 2020, more than 250 things will connect each second. (source Cisco)

− It is estimated that by 2020 there will be more than 50 billion internet connected devices. (source Cisco)

Submarine cables

Fiber optic cables around the world

A single fibre can transmit as much as 100 billion bits per second (100 Gbps, about ten thousand times faster than a typical home broadband connection)

- A cable can contain hundreds of fibres, a single cable can have enough capacity for the communications of millions of users.

Connectivity and information exchange was (and is ) one of the main motivations behind the Internet; but Content and Services are now the key elements;

and all started growing rapidly by the introduction of the World Wide Web.

Internet of Things (IoT)

− Extending the current Internet and providing connection, communication, and inter-networking between devices and physical objects, or "Things," is a growing trend that is often referred to as the Internet of Things.

− “The technologies and solutions that enable integration of real world data and services into the current information networking technologies are often described under the umbrella term of the Internet of Things (IoT)”

Back to the Future: 2013

Applications and potentials

− Analysis of thousands of traffic, pollution, weather, congestion, public transport, waste and event sensory data to provide better transport and city management.

− Converting smart meter readings to information that can help prediction and balance of power consumption in a city.

− Monitoring elderly homes, personal and public healthcare applications.

− Event and incident analysis and prediction using (near) real-time data collected by citizen and device sensors.

− Turning social media data (e.g. Tweets) related to city issues into event and sentiment analysis.

− Any many more…

The physical world data

− Multi-modal and heterogeneous− Noisy and incomplete− Time and location dependent − Dynamic and varies in quality − Crowed sourced data can be unreliable − Requires (near-) real-time analysis− Privacy and security are important issues− Data can be biased- we need to know our data!

− Data alone may not give a clear picture -we need contextual information, background knowledge, multi-source information and obviously better data analytics solutions…

Global Challenges

− Net neutrality− Openness and freedom of access− Privacy and control on personal data− Cyber security and trust− Dependability and resilience − Who owns what, and who controls what− Digital divide − Social impacts

Technical challenges

− (Automated) data to actionable-information process

− Finding and linking complimentary and related information

− Energy resources and bandwidth − Quality of Service − (near-) real-time access to information for

everything/everywhere − Autonomous machine-to-machine interactions − Fast speed networking − Security, privacy, trust for applications and

servcies 71

Let’s hope

−The Internet of the Future will be −Open and accessible for everyone,

everywhere, available at anytime,−People will have control on their data−Data will be used for helping people−Smart applications will contribute to a

better life and to a better use of of our resources in the world!
