Support 50% more devices◦ With minimal additional ARPU◦ Internet of Things, Machine-2-Machine

Lower latencies◦ Messaging, VoLTE, Connected Car

Increased bandwidth◦ More video, more stuff, but especially more video◦ LTE Broadcast

Seamless integration with WiFi◦ Hand-off, policy, control, security

Caching content as close to the device as possible◦ Content servers in local data centers◦ Distributed content◦ Reduce transit for major content

Lower operating costs per device◦ Much lower

Mobile application virtualization◦ Application is separated from the other apps and

services running on the mobile device

Mobile access virtualization◦ Mobile device connects to multiple radio access

networks (RAN) transparently to the user

Mobile network virtualization◦ Mobile network is virtualized◦ EPC can be fully virtualized and run in a data center with

off-the-shelf hardware◦ Mobile RAN virtualization requires splitting of the

conventional base station into a Remote Radio Head (RRH) or Remote Radio Unit (RRU) and a pooled group of baseband processors

Software-defined networks (SDN)◦ Represent a transition away from legacy distributed protocols and

fixed networks◦ Resources are centrally controlled ◦ Transport is allocated across a number of viable alternative

networks◦ Replaces traditional networks that disparate types of network

elements and protocols that are very challenging to manage

Network Functions Virtualization (NFV)◦ Allows network functions to be implemented in software and

deployed on commercial high volume servers, switches and storage elements

◦ Hardware can then be distributed as required, giving the operator more flexibility in how the network is physically deployed

◦ NFV is an intrinsic part of virtualizing the EPC as the virtualized EPC would become a collection of network functions (S-gateway, P-gateway, MME, etc.) which are defined in software and then implemented on commercial hardware using NFV principles

Mobile network virtualization is opportunity and challenge for vendors◦ Opportunity to enable MNOs to cut

costs and support new services◦ Threat that if the vendor does not

move fast enough, others will

Virtualization of the mobile network is here◦ Groundwork laid for RAN

virtualization with RRH architecture later on

◦ EPC being virtualized today◦ Need to maintain service while

evolving

Price wars in the U.S. may hasten virtualization evolution◦ Need to pull costs out of network

operations as APRUs fall◦ Pressure on vendors to deliver at

lower cost◦ “Do more with less, now”

Virtualization and SDN are generational shifts◦ Long term architecture plan,

not short term changes◦ Fundamental change in how

networks are designed, built and operated

SDN challenges include◦ Performance of standardized

hardware◦ Interoperability◦ Co-existence with legacy

network elements Challenge is to evolve

network while maintaining service/revenues◦ Consumer should never notice

the transition◦ Need to manage risk in the

network

What is NuoDB?


What is NuoDB

Distributed, transactional, SQL database, engineered for the cloud


Because single data center is not enough;active-active-active, geo-distribution is becoming table stakes

Because ACID is vital for many critical use cases

Because tools and skills are in place;re-engineering and re-skilling costs are prohibitive
