Grease your hands in the NFV Garage
Calsoft conducted its first ever Twitter chat on 22nd March 2018, Thursday at 7:30 AM PST focusing on the new age technology, NFV, that is succinctly poised to propel technology and business offerings to a heightened level.
Since NFV is getting closer to enter enterprise adoption, this Twitter chat was fashioned to understand the finer nuances of NFV and the technology stack. Participants asked questions on Twitter using #CalsoftNFVGarage to this effect.
We received some questions prior to the event time through our pre-register link on our website and our host for the evening, Pavan Gupta, answered them at the scheduled time for the Twitter chat.
Operators across the globe need to adopt new architectures for deploying and managing their services due to changing nature of service provider business. Network Function Virtualization (NFV) presents a radical architecture that allows operators to move away from traditional proprietary hardware platforms to commercial off the shelf (COTS) hardware for compute, network and storage. Foundation of NFV is based on cloud and virtualization, allowing services to be offered on virtual machines and containers, thereby reducing CAPEX and OPEX considerably. This not only allows operators to make healthy margins in their business but also help create new use cases for service offerings. NFV promotes innovation in service provider industry, which has been throttled due to falling data plan rates and high costs associated in managing existing infrastructure and networks.
NFV is driven by European Telecommunications Standards Institute (ETSI), which has come up with reference architecture. ETSI defines the standards for NFV allowing multiple players to participate to build NFV products and solutions and create a vibrant ecosystem. NFV strongly advocates use of open source software and communities such as OPNFV, ONAP and OpenStack are making headways in that direction. A NFV system is built with a mix of multiple technologies: Orchestrator, VNFs, Cloud, Virtual Networks, Service Function Chaining, SDN Controller, Virtual Machines, Containers, Hypervisors, Data plane acceleration, off the shelf hardware switches and compute hosts.
NFV presents exciting avenues with potential to disrupt service provider business. However, given the initial stages of the technology, there are several challenges that need to be overcome given the diverse set of technologies involved. Mobile and broadband users are becoming more hungry for data and sensitive to variations in quality of service. Clearly, customer experience shouldn’t get affected when NFV is put in use.
