The SDN/NFV topic addresses the move to improve service velocity and simply network management thanks to the introduction of software defined networking (SDN) and network functions virtualization (NFV) technologies.
As the telecom industry gathers at this year’s Mobile World Congress, we’re sure to hear that “5G is here!” and “5G is real!” – just as we have in previous years. But as the real-world challenges of 5G deployments draw nearer for operators, RAN vendors will need to devote some messaging to assuaging operators’ fears. In fact, this has already begun, and it takes the form of RAN vendors emphasizing 5G benefits that are, in fact, more like remedies to problems posed by 5G itself.

Since taking the reins at Cisco in 2015, CEO Chuck Robbins has projected an image of stability, even as the company navigates tricky challenges like the move from hardware-centric to software-defined networks. However, the company has seen a steady stream of executive departures since Robbins’ tenure began.
• Samsung’s bold announcement of $160 billion investment in the future missed an opportunity to highlight its 5G mobile access infrastructure capabilities.
• At this crucial inflection point in the run-up to the 5G era, Samsung’s longtime-underdog RAN business shouldn’t take a back seat in high-level messaging.
Samsung this week announced sweeping plans to invest a total of KRW 180 trillion (or about $160 billion) over the next three years in future growth areas including artificial intelligence (AI), 5G, automotive electronics components, and biopharmaceuticals.
Given the intended impact of the announcement, it’s surprising that Samsung didn’t take the opportunity to make a stronger statement about its role in 5G mobile access infrastructure. True, the release does state that the Korea-based tech giant “will also invest aggressively to become a global player in the advanced markets for 5G chipsets and related devices and equipment.” If that last word can be read to include mobile networking gear, then at least part of a single word in the 820-word message was aimed at capturing 5G networking mind share – not exactly a ringing bell.

Support from AT&T, Verizon, and Rahi Systems is a big thumbs up for both Lumina in particular and hardware-agnostic SDN in general.
The fact that Lumina needs external funding to grow shows that growing organically in the SDN business is still difficult.
At its launch last year as Brocade’s networking business spinoff, Lumina Networks’ value proposition focused on building a service-oriented business, catering open-source, hardware-agnostic SDN solutions to telcos and enterprises. Last week’sannouncement of the company’s successful $10 million funding round (of which $8 million was from Verizon Ventures) validates this value proposition and underlines the confidence large telcos like AT&T and Verizon have in the company’s solutions and business model.

• Segment Routing Deployed in a Backbone Network: Cisco and China Unicom collaboration, a two year endeavor, enables the operator’s nationwide MPLS VPN network to support on-demand services. Cisco notes that this represents China’s first Segment Routing (SR) deployment and leverages its SDN technologies to provide an end-to-end solution. SR also helps mitigate the use of more complicated IP protocols (like RSVP-TE), which is a big advantage and leverages the power of SDN’s centralized management model. .
• Advanced Vendor Services Accelerated Delivery: Cisco’s Advanced Services teams provided full life cycle support and coordination with China Unicom and third-party suppliers, and tackled SDN, NFV, cloud computing, ultra-broadband networking, and related technology issues for the operator. The use of vendor supplied services has always been part of the “vendor – operator” model, but virtualized technologies pose additional time-to-market issues such as mastering new technologies and dealing with the complexity of integrating multiple components.
The announcement by Cisco and China Unicom represents a tangible example of how current infrastructure networks can be transformed to deliver flexible cloud-based services by exploiting new routing and networking techniques, such as segment routing which aligns well with centralized management and control (i.e., SDN) paradigms. What makes the solution significant is the combination of multiple technologies, SR, SDN controllers, service orchestration, and the ability to quickly compute optimal traffic paths through an IP network using a path computation engine (PCE). Individual components on their own cannot deliver the resultant end-to-end solution, which supports China Unicom’s ability to offer a range of named cloud-based services (Cloud Network Connection, Cloud Networking, Cloud Broadband, Unicom Cloud Shield, Intelligent Boutique Video Network, and Boutique Financial Network) which it noted in a joint press release with Cisco.
