Insight-as-a-Service for Satellite Networks - NSR Sep 2018
"The terrestrial telecom industry is fast shifting towards 5G networks, with Software Defined Networks (SDN) and Network Functions Virtualization (NFV) forming key parts of major strategic efforts. This is seen in multiple market movements where organizations such as Verizon, AT&T and Ericsson have begun to shift towards adopting SDN/NFV approaches to manage increasingly complex networks. But what does this mean for satellite players, and how can they remain competitive?

With satellite operators beginning to unlock value behind pixels and bits, the industry is moving downstream towards a data-driven application business. Earth Observation (EO) and Machine-to-Machine (M2M) / Internet-of-Things (IoT) satcom stand at an inflection point. While most of the opportunity will remain in the application layer, a parallel story is emerging in the network layer as well."

"NSR’s Big Data Analytics via Satellite, 2nd Edition report establishes the revenue potential for satellite big data lies largely in the Transportation, Gov/Mil and Energy markets."

"A major driving force of this growth is the increasing complexity of networks."

"... in late 2017, SES used dynamic bandwidth allocation based on SDN principles on its O3b fleet."

September/October 2017 - Bandwidth Management: New Paths in the LEO and MEO Era | Via Satellite
"The advent of new High Throughput Satellites (HTS) will add to the swell of LEO and MEO bandwidth supply. As capacity will likely reach unprecedented levels, can the industry expect a surplus? And would this render bandwidth management less vital? Market players break down the demands and trends, revealing that bandwidth management solutions will see greater importance."

"Looking singularly on satellite networks, there are a few things bandwidth management can do: Adaptive Coding and Modulation (ACM), TCP/IP proxy, compression, caching and the like. However, SpeedCast prefers to think beyond that, explains Berge, adding that customers are benefiting from having hybrid networks and, therefore, the company has a focus on Software Defined Networks (SDN)."

Network security: threats and opportunities for operators
"The software-controlled transformation of CSPs’ organisations and network infrastructures creates both opportunities and risks in terms of network security. The increased openness, speed and flexibility of software-defined networking (SDN) and network function virtualisation (NFV) create a host of new vulnerabilities that increase the level of risk to the organisation and its customers. Conversely, that same openness, speed and flexibility provides the CSP with very much better tools with which to spin-up and deploy security features to detect and mitigate real-time threats in its networks."

"Another example is the risk of DDoS attacks originating in the 5G radio access network. This already represents a threat to network availability in the current 3G and 4G network environments, but this will escalate with the introduction of 5G endpoints capable of supporting up to 100 Mbps. There are new opportunities for vendors in delivering products and feature sets that will meet these new 5G security challenges."

Editor's Corner—Telecom’s move to software and virtualization hounded by the same old problems | FierceWireless May 2017
"For years, carriers and vendors have been touting the wonders of software-defined networking (SDN) and network functions virtualization (NFV). These technologies, the argument goes, will enable network operators to replace expensive, proprietary hardware with software-powered, virtualized services running on cheap, off-the-shelf hardware. The result, vendors and carriers have said, will be an industry that can pivot on a dime, quickly developing and launching new, powerful, revenue-generating services while cutting costs in the process. The result, however, is not quite that. At least not yet."

Level 3 "is reluctant to go much further down that path due to concerns that what the company develops might not interoperate with services from other vendors or carriers"

"AT&T, an early mover in the SDN and NVF space, has said it expects that fully 55% of its network operations will be virtualized by the end of this year. . . . But still, AT&T doesn’t yet have any concrete cost savings it can point to from its virtualized, software-powered migration."

Verizon "said that the operator’s decision to standardize much of its software efforts on OpenStack “is a challenge right now.” "

"But standardization efforts in this area are still in their early phases, and expenses are mounting."

"It’s no surprise that the telecom industry is calling for more interoperability in its migration to SDN and NFV. After all, interoperability is one of the few key tenets underpinning the growth of the global telecommunications industry—communications only work when everyone speaks the same language."

NFV and SDN enable CSPs to stay relevant to their customers in the digital economy - Newsletter – Analysys Mason Quarterly - News | Analysys Mason
"A strong vNGN platform and a streamlined operations approach will support increased relevance in the digital economy provided CSPs build attractive new services on these assets. NFV and SDN Since the commercialisation of the Internet, telecoms has ceased to be a closed market with its own unique standards and processes; we just did not realise it. It has taken the market two decades to come to terms with the business consequences, and for communications service providers (CSPs) and their vendors to realise that increasing their relevance in the wider Internet economy will require significant changes to their organisations and processes. Using virtualisation techniques from IT, including network function virtualisation (NFV) and software-defined networking (SDN) technology to rethink the way communications networks are built and managed is critical for CSPs to rebuild relevance."

Cisco vs. VMware highlights divide in SDN thinking - FierceWirelessTech May 2014
"Chambers said Cisco can lead the SDN market because it is taking a whole-architecture view of the SDN market rather than selling individual pieces. Its proprietary combination of switches, software and security make up Cisco's hardware-centric Application-Centric Infrastructure (ACI), which the company announced almost one year ago. Cisco's approach to SDN and data center orchestration differs starkly from that of competitor VMware. Cisco's non-abstraction approach, not surprisingly, is focused on its long-time core competency around selling hardware. VMware NSX's network virtualization platform with an Ethernet fabric, on the other hand, represents an abstraction approach with software overlay."
