PREVIEW 2017 Trends in Networking DEC 2016 Jennifer P. Clark, Vice President Ken Rehbehn, Principal Analyst Jim Duffy, Senior Analyst, Networking Network infrastructure has always been characterized by slow incremental change restricted by the cost, time and effort needed to deploy connections and hardware. In 2017, trends will underscore the massive change that is transforming the network, enabled by wireless, mobile and virtualization technologies. 2016 451 Research, LLC WWW.451RESEARCH.COM

CLARK VICE PRESIDENT Jennifer P. Clark is Vice President, Network Research for 451 Research. She heads the Network research practice, providing actionable insight into network technology and infrastructure, examining the challenges facing both enterprises and network operators in provisioning the local, wide-area and radio access networks, and the solutions and technology that will meet the demands of 4G and 5G mobile networking, cloud computing and the Internet of Things (IoT). Jennifer s personal areas of research include software-defined networks (SDN), network functions virtualization (NFV), network orchestration, mobile backhaul, network policy management, the Evolved Packet Core, DNS, IPv6, carrier Ethernet, and core and edge routers.

Key Findings Software-defined WAN (SD-WAN) adoption will effectively cap further investment in the multi-billiondollar MPLS VPN market by lowering costs for last-mile connectivity while improving ease of operation and activation speed. Enterprise networking vendors will pay billions for remaining wireless LAN (WLAN) pure plays to stoke their growth engines for at least the next decade. IoT, analytics and security initiatives will expand in 2017 and ownership of WLAN assets will be integral to fulfilling these initiatives. Network and service orchestration and management is still baffling the mightiest of carriers; it will be the single largest deterrent to large-scale carrier deployment of software-defined networking (SDN)/ network functions virtualization (NFV) in 2017. LTE Advanced Pro will stand as the most important 3GPP release since the launch of LTE, while 5G will continue under development. The year will be one of preparation for Korea s pre-standard 5G demonstrations during the 2018 Olympic Games as well as possible pre-standard deployments for fixed wireless access. III
Executive Summary INTRODUCTION Networking is exciting again. We have heard this repeatedly at recent industry conferences and events. After years of evaluating speeds and feeds or weighing the merits of competing protocols we are, in 2017, fundamentally changing the way we build and use networks. In every science fiction TV series, there is an episode where some humanoid makes an evolutionary leap forward and sheds its physical body, transforming to pure energy no boundaries, everywhere at once, with expansive knowledge. This is a pretty apt analogy to what s happening in the network, starting with the dissolving edge as enterprises reach out to their remote offices with software-defined WAN (SD-WAN) connectivity and connect more users and devices through wireless LAN (WLAN) technology. All of our 2017 trends underscore the impact of wireless, mobile and virtualization technologies. Each of these technologies is moving us closer to our goal of seamless connectivity anywhere, anytime between any group of users, devices or applications. Our first trend examines the impact of virtualization, in the form of SD-WAN, on enterprise networking. Enterprises now have the choice of moving from MPLS-based VPN connectivity to a less expensive, more flexible and more operationally straightforward software-defined WAN (SD-WAN). The dozens of SD-WAN startup vendors and service provider implementations are a testament to the momentum behind this new technology. So too is our estimate of nearly 20% CAGR of SD-WAN revenues through 2019. In our second trend we look at the M&A activity around WLAN. WLANs today are the predominant enterprise campus network access medium, as mobility and cloud transform IT. We expect to see enterprise networking vendors in the coming year pay billions for remaining WLAN pure plays to position themselves for growth for the next decade. WLANs and access point aggregation switches are blurring the edge of the network with software-defined networking (SDN), virtualization and cloud management, imbuing the network with the same dynamic, on-demand characteristics that we are seeing in the storage and compute environments. The service providers are part of this change, transitioning their network architectures with SDN and network functions virtualization (NFV). They are challenged in this transition by the size and complexity of their networks, particularly when compared to the relative immaturity of the SDN and NFV offerings. Network and service orchestration will remain the most perplexing elements in the new network architecture with dozens of competing products, standards and open source projects. However, 2017 will see the service providers make headway in other transition trouble spots, such as overcoming organizational resistance and selection of NFV infrastructure. The mobile cellular network is the lynchpin of the trend toward dissolving the network edge and connecting a continuously expanding community of users, applications and devices. However, while 5G technology may continue to grab headlines in 2017, as the carriers and their customers debate the technologies and use cases that will characterize 5G, it will be LTE Advanced Pro that does most to move the radio access network (RAN) environment forward. New capabilities in 3GPP Release 13 for cost-effective low-power, wide-area (LPWA) IoT support open up a market previously denied to operators. Emerging competition from license-exempt LPWA IoT network options such as SIGFOX and LoRaWAN galvanized the mobile network operators (MNOs) and the 3GPP to settle on a new IoT radio access protocol for Release 13 called narrowband IoT (NB-IoT). Release 13 also provides a dramatic injection of license-exempt spectrum to supplement limited and costly license spectrum assets and specifications covering mission-critical services such as push-to-talk, which is important for public safety networks.
