Why We Have to Embrace Complexity for Reliability, Availability and Serviceability of Future Networks and 5G

The decoupling of software architectures from hardware infrastructure (SDN) and the virtualization of resources and functions (NFV) are opening several new and intertwined challenges for future networks: one of them is “Complexity”, a systemic challenge. In fact, future 5G infrastructures will assume the form of extended and distributed execution and communication environments—from fog resources (up to the smart things and terminals) to edge- (e.g., network points of presence and small/medium-sized data centers), to cloud computing (e.g., big data centers) and across a transparent and pervasive fixed-radio connectivity. On top of the 5G infrastructures will reverberate a boom of network, cloud services and user applications, enabling a scenario of Everything -as-a-service, where everything will be an instrument to provide and consume ICT services and data. So, Future Networks and 5G will be like Complex Systems of Systems. It is a commonplace conclusion in sciences today that higher order phenomena cannot be directly derived from lower order systems: emerging properties and dominant characteristics in complex systems come from the interactions between its entities, rather than from the properties of a single entity in isolation. It is argued that Complexity management should be embraced for meeting the requirements of Reliability, Availability and Serviceability of Future Networks and 5G.

“Why Software Is Eating the World”

Marc Andreessen coined his famous

sentence “Why Software Is Eating the

World” in The Wall Street Journal six years

ago.

Today, the idea that “every company needs

to become a software company” is

considered almost unavoidable to be

efficient, effective and able to compete in

such a dynamic market.

Since 2007 concepts such as Programmable

networks and Software networking were

discussed in Research… …Software is eating the Telecoms

SOFTWARIZATION: a systemic transformation

A number of techno-economic drivers are steering the evolution of current network and

service platforms towards Future Networks and 5G

Among these techno-economic drivers, there are:

diffusion of ultra-broadband,

technology advances in chipsets and IT hardware and tumbling costs,

new emerging network paradigms (SDN, NFV),

evolution of Cloud Computing towards Edge and Fog Computing,

growing availability of Open Source software,

more and more advances terminals, smart things, etc…

The combined effect of these drivers are creating the condition for a “perfect storm”

transforming – systemically – Telecoms’ infrastructures and related biz.

Software Defined Networks

SDN: separation of software (e.g., control plane) from hardware (e.g. data plane, packets

forwarding) and execution of the control software on dedicated IT resource local or even in the

Cloud/Edge (i.e., not necessarily in the node).

Network Function Virtualization

Virtualization of network functions (e.g. middle-boxes) and the optimised dynamic allocation

and execution (e.g., general purpose hardware of Cloud – Edge or even Fog Computing).

SOFTWARIZATION: a systemic transformation

Softwarization will enable IoT ecosystems

Softwarization is transforming – for the first time – the Telecommunication

infrastructures in a “continuum” of virtual resources, functions and services

which are extended from the terminals up to the Clouds.

Softwarization will enable Industrial Internet and Industry 4.0 ecosystems


http://goldberg.berkeley.edu/cloud-robotics/

What if robots and automation

systems were not limited by onboard

computation, memory, or software?

Rather than viewing automated machines

as isolated systems with limited

computation and memory, to view them

connected to the Cloud to create a a global

network system embedded into the reality.

Potential impacts in the "Internet of

Things", "Smarter Planet", "Industrial

Internet", and "Industry 4.0."

Cloud Computing

Softwarization will exploit computational intelligence everywhere

Softwarization will allow developing very flexible and

programmable infrastructures for:

• sensing, collecting and storing (even locally, in the

Edge/Fog resource and even devices) massive data sets

(through sensors, terminals, smart things, intelligent

machines);

• moving sets of data or code (through high bandwidth and

ultra-low low latency connections) where it is more

convenient (execution of virtual functions and services );

• elaborating (DL, ML, Industrial mathematics…) big data

(Cloud and Edge/Fog Computing) to infer decisions for

actuating/controlling local actions (pervasive machines).

…it’s about exploiting computational intelligence everywhere!

Complexity is becoming systemic challenge for future networks:

In the future we are not managing closed equipment but intertwined software processes (e.g.,

two orders of magnitude more and much more dynamic);

Computational intelligence will be everywhere

Future networks will assume the form of extended and distributed execution and

communication environments, based on a “continuum” of virtual functions and resources:

…from fog resources (up to the smart things and terminals) to edge- (e.g., network points of

presence and small/medium-sized data centers), to cloud computing (e.g., big data centers)

and across a transparent and pervasive fixed-radio connectivity;

a sheer number of apps/services (e.g., from network to cloud services up to Users’

applications) will on top of such infrastructures.

Complexity: the property of any intelligent system


14

Robustness vs Complexity

Softwarization creates the need of different ways to design networks and services


15

Complexity will be a property of Future Networks and 5G

Lower Bound of Complexity (static, brittle, predictable performance)

Upper Bound of Complexity (flexible, unpredictable performance)

How “taming” this Complexity ? …or better how extracting “simplicity” out of it

How taming the complexity ?

”constraints that deconstraint”

A Network Operating System will create ”constraints that deconstraint”

5G: much more than 4G + 1…

5G: much more than 4G + 1… In fact, 5G is not just an increase of bandwidth, better performance and improved reliability:

5G will be become a sort of "nervous system" of Digital Society, capable of bringing

computational intelligence everywhere to create new services

Conclusions

Software is eating Telecommunications;

future networks and 5G will be Pervasive Software

Environment;

this “softwarization” will bring a new wave of computational

intelligence everywhere;

complexity will be a property of future networks and 5G, as it

is for any “intelligent” system;

the Network Operating System will set those “constraints

capable of de-constraining”, i.e. will allow extracting that

simplicity (in terms of abstractions) required for Reliability,

Availability and Serviceability of future networks and 5G.
