Prime Time to The Big Shift to the IPv6 Internet

 

The transition to IPv6 did not happen over the past decade with the objectives of achieving a smooth and low-cost Internet sustainability through incremental refresh of technology. The reasons can be traced back to the mixed messages sent to industry: hard-to-justify ROI; address depletion confusion and the lack of market demand.  IPv6 is a worldwide and large-scale plumbing exercise. Only engineers should fix it and offer IPv6 as an extended service to sustain the Internet growth and continuity. Now, it's abundantly clear that the address space has evaporated in front of our eyes, putting an end to the growth of the Internet. The address space has melt down in February 2011 at IANA level and by end of 2012 at Registry level in Asia and Europe/Middle East. The transition is not well prepared and there will be winners and losers. Pioneers will benefit from the head start. Followers cannot predict what will happen to them. This is the first time the Internet will get a face lift and probably the last one for decades to come. The lessons learnt from this is that it takes a lot of patience and passion to bring this transition to fruition.  

Essentially:

-       The Internet community has mistakenly focused on the IPv4 address depletion as the problem to be resolved by IPv6 for the ISPs for connectivity to web sites and forgotten to address the many issues that will affect the adoption of IPv6 by the enterprise and the critical infrastructure that are brought in by a transition from an established protocol (IPv4) to a new protocol (IPv6) 

-       The transition in the enterprise should be focused on a “secure transition” and a “secure integration” of IPv6. The only viable secure transition is the “secure Dual-stack” transition. All other transition mechanisms are not secure and will even drill in new vulnerabilities in the critical infrastructure networks to name the important one. 

-       The transition to IPv6 has to be done in the first phase to sustain not only technology parity between IPv4 features but also business models parity. 

-       The current deployment of IPv6 is done with IPv4 network management tools. This is a fallacy as IPv6 is a new protocol with totally different functions and features. It should be deployed with new management tools designed to cater for IPv6 features not just mimicking IPv4 and NAT. In the second phase, IPv6 should be deployed with its built-in functionalities (multicast, mobility, end to end...) 

-       The security in IPv6 is again not deployed, similarly to IPv4. Security is mandated in IPv6 but still no security house or solutions start with secure functionality. 

-       IPv6 Privacy Address is deployed only by Microsoft. All other vendors have not yet realised the randomizing features of the MAC address. 

-       The cost of deploying IPv6 is from now on a costly fork-lift upgrade for those that have not taken the early step of deployment. The cost of not doing anything is even higher. 

-       What is at stake is the “modernisation of the networks” to cater and be securely ready for all new emerging Internet based solutions like Internet of Things, Smart Grids, Cloud Computing, Smart homes and Buildings, Smart Cities, Mobile networks such LTE and Safety networks to replace aging TETRA, Mobile social networks beyond Facebook and Twitter, Mobile Internet cars, Mobile Military networks, Smart Agriculture and Food chains, Smart manufacturing, Mobile Smart Banking, … a Smarter world.

Abstract

Since Marconi demonstrated the feasibility of radio transmissions, researchers have endeavoured to fulfill the dream of flawless wireless multimedia telecommunications, creating the impression of tele-presence - at the touch of a dialling key, with its joy and wonder...

Commencing with a light-hearted historical perspective on the generations of wireless systems, Shannon’s lessons are contrasted with the practical constraintsimposed on state-of-the-art multimedia communicators, such as Iphones and tablet computers. Facilitated by the radical research advances in both wireless solutions and in semi-conductors over the past three decades, three orders of magnitude transmissionrate

improvements have been achieved since the conception of GSM...

However, at what price? This 1000-fold throughputincrease results in a potentially commensurate powerdissipation, which is only partially compensated by the advances in low-power electronics. Furthermore, the energy-prices also escalated over the past few decades

- clearly, the current trend is economically unsustainable!

Finally, the ICT industry contributes an ever-increasing fraction of the global CO2-emissions, which is ecologically unsustainable...

To counteract these trends, in recent years the centre of gravity in research has been shifted from increasing the bandwidth-efficiency towards improving the power-efficiency, leading to the concept of ’green’ radio systems. This presentation will consider a range of wireless efficiency metrics and provides a broad perspective on improving the energy-efficiency of wireless systems. No single solution is capable of radically changing the broad picture. However, it is clear that- in contrast to the classis logarithmic Shannonian capacity law that requires an exponentially increasing power for linearly increasing the throughput - solutions are sought, which only require a linearly increasing power...

Abstract

ON MANAGING HETEROGENEITY IN PRODUCTION CLOUD COMPUTING ENVIRONMENTS

The past few years have witnessed the rise of cloud computing, a paradigm that harnesses the massive resource capacity of data centers to support Internet services and applications in a scalable, flexible, reliable and cost-efficient manner. However, despite its success, recent literature has shown that effectively managing resources in production cloud environments remains to be a difficult challenge. A key reason behind this difficulty is that both resources and workloads found in production environments are heterogeneous. In particular, large cloud data centers often consist of machines with heterogeneous resource capacities and performance characteristics. At the same time, real cloud workloads show significant diversity in terms of priority, resource requirements, demand characteristics and performance objectives. Consequently, finding an effective resource management solution that leverages resource heterogeneity to support diverse application performance objectives becomes a difficult problem.

The focus of this talk will be on understanding the research challenges introduced by resource and workload heterogeneity in production cloud environments. We will first provide a characterization of workload and resource heterogeneities found in production data centers, and highlight the key challenges introduced by them. We will then describe our recent work towards addressing some of these challenges. Finally, we will outline several key directions for future research.
