BackgroundBackground
• We planned BDREN in 2006-2008.
• A US Fulbright Program sponsored investigation hosted by BRAC University
• The goal was not only to solve bandwidth issue for the universities but it has to create a sustained value..
• An infrastructure which can lead in adopting latest technology- a network where researchers, engineersof the country can showcase new technologies.
• An instrument for the country to be at the fore-front of communicationinnovations.

BackgroundBackground
• This is a unique time in history, The emerging innovations are poised torevolutionize our way of life. Starting from telegraph, fixed and mobilephone, internet eras- we will be entering into a new age of ubiquitouscommunication and computation and networked society..
• Smart citizen & community, augmented reality, bots, autonomous cars,smart home, cloud, bitcoin..
• Network is central for becoming a Smart DigitalNation- Future network

Diffusion of Innovation TheoryDiffusion of Innovation Theory
People have different levels ofreadiness for adopting newinnovations and that thecharacteristics of a product affectoverall adoption -Everett Rogers
Rogers classified individuals into five groups: IInnovators, early adopters, early majority, latemajority, and laggards. In terms of the S curve,innovators occupy 2.5%, early adopters 13.5%,early majority 34%, late majority 34%, and laggards16%.

Cloud-Based Radio Access Network (C-RAN)Cloud-Based Radio Access Network (C-RAN)
• execute most of the functions (Controllayer) of a macrocell base-stations(MBS) in the cloud.
• Data layer: It contains heterogeneousphysical resources (e.g., radio interfaceequipment) and performs signalprocessing tasks (e.g., channeldecoding, demultiplexing, and fastFourier transformation).
A basic cloud-based architecture for 5G networks.

Benefits of Agile NCIBenefits of Agile NCI
• Major reduction in Capex equipment costs through consolidating equipmentinfrastructure and exploiting the economies of scale of the IT industry.
• Supporting multi-tenancy thereby allowing network operators to provide tailoredservices and connectivity for multiple users, applications or other networkoperators, all co-existing on the same hardware with appropriate secure separation ofadministrative domains.
• Carrier grade resilience at low cost. Temporarily repair failures by automated re-configuration and moving network workloads onto spare capacity with remoteorchestration. Reduce the cost of 24/7 operations by mitigating failures automatically.

Benefits: Innovation EcosystemBenefits: Innovation Ecosystem
• Eliminating the need for application-specific hardware and employee skill. The skillsbase across the industry for operating standard high volume IT servers is much largerand less fragmented than for today’s telecom-specific network equipment.
• Minimization of the typical network operator’s cycle of innovation. Economies ofscale required to cover investments in hardware-based functionalities are no longerapplicable for software-based development. Possibly, run production, test andreference facilities on the same infrastructure. Reducing development costs and time tomarket.
• Green IT: Reduced energy consumption. Concentrate the workload on a smallernumber of servers during off-peak hours.

Cloud: Computing+Data is now Moving Into CoreCloud: Computing+Data is now Moving Into Core
• Content Delivery Network (CDN): Network provides content owners storageof data . So it can placed closer to downloaders. Faster speed of access.
• Infrastructure as a Service (IaaS). Cloud provides consumer processor,storage, and networks. The consumer has control over operating systems,storage, and deployed applications; Lower HW Capex!
• Platform as a Service (PaaS). Consumer to deploy consumer-created oracquired applications created using programming languages, libraries,services, and tools and the processor, storage, and network provided by theCloud Provider. Lowers HW+OS Capex!
• Software as a Service (SaaS): Cloud also provides full software serviceincluding the application running on a cloud infrastructure. LowerHW+OS+SW Capex!
