SDN ( Software Defined Networking )
NFV ( Network Functions Virtualization )

Telecom Training Workshop : 3 Days

Traditional networks have been designed with purpose-built network equipment (e.g., Routers, Ethernet switches, EPC hardware, firewalls, load balancers, etc.) based on vendor-specific hardware and software platforms. Deploying these monolithic network elements has resulted in long development and installation cycles (slowing time-to-market for new products and services), overly complex lifecycle management practices (adding to operational inefficiency and overhead) and increasing levels of investment driven by escalating customer demand at a rate that exceeds revenue growth.

An operator’s network is currently composed of a variety of “bundled” network elements, where the control, management, and data (user data traffic) functions are physically tied together and the bundled network elements are each provided by the same supplier. Deployment of new services or upgrades or modifications to existing services must be done on an element-by-element basis and requires tight coordination of internal and external resources. This bundling limits operational flexibility while increasing reliance on proprietary solutions from suppliers. The goals of the SDN-NFV provide the following Operational Efficiencies

  • Elastic, scalable, network-wide capabilities
  • Automated OAM&P; limited human touch
  • Dynamic traffic steering and service chaining
  • Time-to-market improvements; elimination of point solutions
  • Agile service creation and rapid provisioning
  • Improved customer satisfaction

The following are key features of the network based on SDN and NFV:

  • Separation of control and data plane;
  • Virtualization of network functions;
  • Programmatic control of network;
  • Programmatic control of computational resources using orchestration;
  • Standards-based configuration protocols;
  • A single mechanism for hardware resource management and allocation;
  • Automation of control, deployment, and business processes;
  • Automated resource orchestration in response to application/function needs.

Combining these techniques facilitates dynamic adaptation of the network based on the application, increases operational flexibility, and simplifies service development. Functions may be dynamically scaled to meet fluctuations in demand. SDN and NFV together change the traditional networking paradigms.

Network Functions Virtualization (NFV) will drive dramatic cost reductions while also accelerating service delivery. Using NFV with SDN, network owners can provision new functions rapidly on demand, improve scalability, and leverage microservices. Benefits like these will make NFV indispensable for service providers, mobile operators, telcos, and enterprises alike.

Network Functions Virtualization (NFV) with SDN is the practical introduction to NFV’s fundamental concepts, techniques, and use cases. The course is for wide audiences of network engineers, architects, planners, and operators, it assumes no previous knowledge of NFV architecture, deployment, or management.
