02 INTRODUCTION
Build your virtualized telecommunications network with NetApp and you will gain a proven carrier-grade approach to data availability, performance, security, and management.
Removing the traditional network silosThe telecommunications industry has always depended on proprietary hardware appliances. This has resulted in silos in which carriers have been forced to unsustainably spend billions year after year. These silos have also prevented carriers from innovating in line with market demand, anchoring them to extremely long deployment cycles for new network services. All of this has contributed to unbearable corporate debts and to a lack of competitiveness towards over-the-top service companies.
Only now, communication service providers (CSPs) are tackling this issue by virtualizing their telecommunications networks and look into new software-defined and cloud-like frameworks with network function virtualization (NFV).

10 CHALLENGES
1. Unproven products or solutions The move to NFV and software-defined networks (SDN) confronts carriers with a world of new products and solutions, and with an increasing number of suppliers they can choose from. The solutions available today are generally not mature enough because still in a developing stage, and this lack of maturity is reported to be one of the main inhibitors for the adoption of NFV by the carriers. Other concerns address the complexity of end-to-end provisioning in both virtual and physical worlds and the need to reskill the telecommunications staff.
02
2. Unknown resource needs All CSPs have one thing in common: They are often completely in the dark when it comes to determining the amounts of computing, networking, and storage resources they will need to enable their network transformation. Testing and implementing technologies for NFV and SDN, and aligning everything to business models, takes its time and often exceeds the forecasted resources. What starts as a proof of concept is very likely to evolve unforeseeably and dynamically. Carriers are then forced to rearchitect their solutions on the fly and risk increased costs.
11 CHALLENGES
3. Massive transformationCarrier networks can consist of hundreds or even thousands of large central offices (COs) and points of presence (PoPs). Turning to a NFV infrastructure means to transform most of them into data centers of adequate sizes and decide for either a centralized or a distributed NFV use case deployment. Carriers will also need to make sure that their platform of choice can provide redundancy across all locations to ensure business continuity and to dynamically rearrange data allocation. This part of the journey poses not only a massive task from a planning perspective. It also means significant operational challenges before an effective end-to-end management becomes real.
12 CHALLENGES
4. Operational challenges 1/2
The new NFV framework is mostly about increased agility. However, carriers need to ensure also that the products or solutions they deploy can live up to carrier-grade levels. In a nutshell, deploying NFV is not simply a matter of ripping and replacing network hardware. It requires a holistic view for a process with many implications.
13 CHALLENGES
+ Brings operational challenges in terms of relation- ships and changes in physical and virtual worlds
+ Needs to reflect the hierarchies in a distributed multitier network
+ Requires a fully virtualized and integrated infra- structure stack to support carrier-grade reliability, similar to the availability, performance, and quality of service (QoS) of physical deployments
+ Needs a totally new set of skills of the carrier staff
14 CHALLENGES
4. Operational challenges 2/2
02
5. Towards a DevOps modelThe operational challenges outlined earlier demand that carriers adopt a DevOps-oriented organization. Only an ongoing and integrated process of continuous development and continuous deployment can deliver on the agility promises of NFV and SDN. Only when their developers and operators work hand in hand, CSPs can innovate and adapt to customer demands and market conditions much faster.

17 DATA MANAGEMENT
Virtualization in general and NFV in particular brings consolidation and choice especially in the hardware arena. Coupled with commoditized hardware, virtualization promises to reduce costs quickly, but does not provide any added value by itself. What does that mean for carriers? Whatever functions CSPs want to virtualize they will need different resources in different qualities and amounts to work properly and meet QoS requirements. Depending on the use cases, it is the data management that impacts the speed, scalability, and availability of a service.

18 DATA MANAGEMENT
Let’s have a look at a real-world scenario, a virtualized content delivery network (CDN) to illustrate the value add of data management.
Basically, the virtualization of CDN functions, including analytics, policy management, and on-net/off-net streaming, is applicable to a NFV and SDN deployment across the data centers within a carrier network. However, the biggest challenge is to dynamically allocate resources closer to the network edge to optimize cost savings
and subscriber QoS. For this, service providers will need a management solution that allows on-demand, scale-out and scale-in resource caching at peak hours. Only then it is possible to achieve a superior customer experience as well as traffic optimization on controller- and cache-node level.
Importance of data management in addressing these challenges
19 DATA MANAGEMENT
Storage can become a bottleneck for several virtualized network functions (VNFs) due to capacity and performance reasons.
CDN or deep packet inspection requires a dynamic distribution across
a CSP’s network of COs and PoPs. It is critical that every PoP can support
a storage-intensive VNF any time.
vCPE, vSTB, and moreneed 10s of 1,000s instantiated virtual
machines (VMs) or containers. This applies certainly to a mobile user environment and will
in general turn a small storage requirement into a big one, where storage access
performance can become a major issue.

For this, service providers need a storage management solution that allows on-demand, scale-out and scale-in caching resources at peak hours.

26 CLOUD & NETWORK
The NetApp value for CSPs: Network meets the cloud
As outlined earlier, data mobility is a critical factor. Basically CSPs need data mobility for two reasons. First, CSPs need to ensure data replication between sites, including business continuity for their infrastructure. Secondly, CSPs need to ensure that they can dynamically move network functions and services from one CO or PoP to another. Altogether data mobility across COs and PoPs becomes the enabler for service availability and quality. The failure to ensure data availability and mobility will only prevent silos to be completely removed from the carriers networks. NetApp delivers on the promise of data mobility with its Data Fabric strategy which allows data to be accessed where it is needed most. Data Fabric delivers exactly on the needs of CSPs and enables them to innovate and generate new revenue streams driven by new business models.
