Thundercloud formation – condensing the mobile cloud out of thin air

Professor Jon Crowcroft FRS, FREng, FIEEE, FACM, FBCS, FIET

In previous work on Crowd Computing, and on Droplets, we proposed distributed cloud computation on mobile devices only, and on fixed wireless domestic devices, respectively. In other work, many researchers and practioners have proposed offloading work from the mobile device to the traditional “big iron” cloud infrastructure.

The advantages of a fully decentralised system are many, including less threats from coercion, more resilience to attack, less resource use in terms of core networks, and therefore less power consumption, and potentially, lower latency between the user and the delivery of results.

However, the complexity of decentralised systems is a high barrier to their adoption.

In this talk, I will discuss some of our ideas for incentivising this adoption including our MISO toolkit (Mirage, Irminsule, and Signposts on Ocaml) under the Nymote initiative.

Impact of cloudification and virtualisation on the performance of mobile services and mobile networks

The current trend of cloudification and virtualisation in the network service provider infrastructure will offer cost-optimised operations and maintenance of the network. Principles like Software Defined Networking (SDN) and Network Function Virtualisation (NFV) are the main drivers of this trend. The trend includes different directions of optimisation and is driven also by mobile network operators. Mobile network architectures and platforms such as the service delivery platform – IP Multimedia Subsystem (IMS) – as well as the mobile core – Evolved Packet Core (EPC) – are good candidates for cloudification and virtualisation. In addition to the virtualisation of the control plane (e.g. EPC) it is currently discussed to move alos the user plane into the cloud. This will have an impact on the performance for instance of time critical services and applications. Another example is the effective use of bandwidth resources such as local break-out mechanisms. The current SDN and NFV discussions should include such examples and  should consider performance-effective solutions.
