Virtualizing Telco Networks

  1. 1. Virtualizing Telco Networks Achieve Genuine Innovation by Governing Your Data
  2. 2. 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.
  3. 3. Removing the traditional network silos The 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.
  4. 4. 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).
  5. 5. New Business Models Matters as Much as Economics Embracing
  6. 6. Choice Broader software ecosystem Economics Powerful for organizations with large networks Innovation No specialty hardware, more competition Savings Eliminate costly hardware upgrades Flexibility Do things faster by deploying new services as software-only

  9. 9. Challenges Deploying NFV: Needs and operational challenges Page 09
  10. 10. 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.
  11. 11. 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
  12. 12. 3. Massive transformation Carrier 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
  13. 13. 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
  14. 14. + 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
  15. 15. 5. Towards a DevOps model The 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. 15 CHALLENGES
  16. 16. Data Management Data in NFV cloud- based environments Page 16
  17. 17. Importance of data management in addressing these challenges 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. speed scalability availability
  18. 18. 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. 19. 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 more need 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. Storage-intensive VNFs Performance-intensive VNFs Importance of data management in addressing these challenges
  20. 20. Video streaming is an example of a storage-intensive VNF Considerations A virtualized CDN can take advantage of an NFV and SDN cloud-based deployment across the carrier network data centers. Carriers need to dynamically allocate resources closer to the network edge, to optimize cost savings and QoS. For this, service providers need a storage management solution that allows on-demand, scale-out and scale-in caching resources at peak hours. 2015 2016 2017 2018 x 6 x 24 x 13 Capacity and Performance Requirements 20 DATA MANAGEMENT

  27. 27. Network & Cloud Network meets cloud: NetApp value to CSPs Page 27
  28. 28. 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 carriersˇnetworks. 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. 28 NETWORK & CLOUD
  29. 29. Network Services Across Multiple Service Providers Data Fabric is NetApp’s vision and strategy. Hybrid Physical and Virtual Infrastructures Capacity planning, trouble-shooting, reporting, for own and third parties with OnCommand® Insight. Cloud and Network Operations Collaboration The same workflows can be used by both teams with one single tool. Dynamic Changes to Physical and Virtual Device Configurations NetApp provides a very large set of API calls, which transform the storage in a set and forget platform. Many-to-Many Services and Infrastructure Relationships NetApp secure multitenancy has been audited and certified by specialized companies. Dynamic Software and Hardware Relationships NetApp primes efficiency, which implies speed of execution, for example, when cloning objects.
  30. 30. To maintain availability, adjust capacity, or load balance physical resources, software running on VMs or containers can be moved between physical servers or replicated to run on newly created VMs or containers. Dynamic relationships between software and hardware components CSPs can dynamically allocate resources or quickly move data between storage nodes without impacting services or collocated VNFs. All NetApp features are linked to efficiency. This includes fast execution, for example, when cloning objects. With NetApp Unique Value Proposition 26 CLOUD & NETWORK30 NETWORK & CLOUD
  31. 31. To accommodate the dynamic nature of virtualized networks, end-to-end management systems must be able to adjust device configuration. Dynamic changes to physicaland virtual device configurations With NetApp Unique Value Proposition There is no need for manual storage intervention. Every single possible task can be done through APIs which integrate NetApp systems with NFV architectures. NetApp provides a very large set of API calls which transform the storage in a “set and forget” platform. 26 CLOUD & NETWORK31 NETWORK & CLOUD
  32. 32. A virtualized network service can rely on several VNFs which may be running on one or more VMs. A single VNF may also support several network services. And the group of VNFs supporting a single network service might be running on several physical servers. Many-to-many relationships between network services and underlying infrastructure Using secure multitenancy, CSPs can run several instances on the same storage platform, while keeping VMs isolated on both storage and network. NetApp secure multitenancy has been audited and certified for its security by specialized companies. With NetApp Unique Value Proposition 26 CLOUD & NETWORK32 NETWORK & CLOUD
  33. 33. With NetApp Unique Value Proposition CSPs can choose from several infrastructure monitoring tools such as OnCommand Insight as well as integration through open APIs. OnCommand Insight is a monitoring tool, but serves as well for capacity planning, trouble- shooting, and reporting in an end-to-end heterogeneous infrastructure, including storage, SAN, Ethernet, hypervisors, and VMs. 26 CLOUD & NETWORK33 NETWORK & CLOUD As virtualization is adopted gradually, carriers must be able to integrate virtual environments into their existing infrastructures for end-to-end traditional or legacy monitoring. Hybrid physical and virtual infrastructures
  34. 34. 26 CLOUD & NETWORK34 NETWORK & CLOUD Some of the VNFs comprising a virtualized network service may be hosted in the clouds of multiple collaborating providers. Network services across multiple service providers Customers have a common set of secure data services to manage, access, and protect data where it is needed most. Data Fabric is NetApp’s vision and strategy for data management. With NetApp Unique Value Proposition
  35. 35. With NetApp Unique Value Proposition Automatization using APIs or predefined workflows help manage end-to-end infrastructures. Cloud and network operations staff can define and use the same workflows through a single tool. 26 CLOUD & NETWORK35 NETWORK & CLOUD Organizations will need to cooperate effectively to establish new operational processes that meet the demands of end-to-end management of hybrid infrastructures.
