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.
• Webscale influence on new product developments is being felt in data center interconnect and massively scalable switching and transport gear.
• Traditional telcos, however, are using these new Webscale-driven platforms to retool their own networks and prepare to deliver more agile services to protect their service base.
Since the first public networks were built, incumbent telcos like Vodafone, Deutsche Telekom and AT&T have ruled network equipment roadmaps and investments – dictating the features, operation and capabilities of new networking products. However, more recently Webscale operators are the influencers. Whereas vendors had been focused on providing the high capacity and broad coverage required by rapid smartphone adoption and a massive increase in video traffic, the focus has steadily turned to support massive, low-latency throughput between the data centers that serve the most popular brands on the Internet, dubbed FAMGA (Facebook, Apple, Microsoft, Google and Amazon). Traditional network operators are scrambling to adapt to this change in service delivery focus, and better prepare their networks for the emerging 5G and Internet of Things (IoT) era.

New base station introductions in the run-up to 5G pose challenges depending on both their timing relative to competitors’ moves and their messaging relative to legacy products.
All major RAN vendors have faced challenges unveiling new base stations recently, including Huawei, which was forced to make big changes in response to shifting market demands.
Everywhere you look, people are talking about the coming migration to 5G mobile networks. A much less talked about – but perhaps no less challenging – transition is the one radio access network (RAN) equipment vendors are making from base stations that were optimized for LTE to ones designed to lead operators into the 5G era. Yet, in the waiting period before 5G’s true arrival, marketing new base stations aimed at future networks alongside the current generation of base stations is a balancing act akin to stepping from an unmoored boat to a pier.

Turbulence in the NFV MANO market is high; that can be good to shakeout problems, but it also makes for an uncomfortable flight.
Some operators have decided to take matters into their own hands; others are engaging a trusted vendor to “just make it work”.
As with any long haul flight, the risk of experiencing periods of turbulence is ever present. The flight metaphor is also appropriate to long haul telecom network transformation projects, and NFV is certainly the largest to be navigated by the industry in the past 20 years. The NFV management and network orchestration (MANO) architectural block is a good indicator of the “flight status” of the whole NFV project, which now seems to be entering a new phase of turbulence. A couple of recent announcements have highlighted some major, and sometimes forgotten, basics: Continue reading “NFV MANO – Entering Yet Another Bout of Turbulence”→
Introduces Slicing for Backhaul: The ZXCTN 609 supports separate backhaul slices (tunnels), each with independent performance characteristics, meeting 5G demands for low-latency, high-speed, flexible connections.
100G Backhaul Link Support: The ZXCTN 609 expands ZTE’s Flexhaul series to support 100G links to handle expected high-bandwidth 5G backhaul speeds, with high-availability features such as protection switchover and SDN control.
ZTE leveraged this year’s MWC Shanghai 2017 to further its stake in the emerging 5G infrastructure market by expanding its Flexhaul series backhaul platform to support 100G links. 100G is needed to cope with the massive capacity requirements expected as 5G comes to life in the next few years. The ZXCTN 609 also includes the company’s FlexE tunnel technology, which it announced as part of the ZXCTN 6180H launch, bringing the equivalent of network slicing to the backhaul network. ‘Flexibility’ is clearly the focus, with FlexE supporting a variety of service characteristics for applications such as enhanced mobile broadband (eMBB), massive machine type communications (mMTC), and ultra-reliable and low-latency communications (uRLLC), which have vastly different transport requirements. ZTE has collaborated closely with multiple operators to craft mobile network solutions that meet a range of application types and capacities. In addition to being visible in China Mobile and Ncell Axiata, ZTE successfully completed tests in seven major scenarios that are part of the second phase of China’s national 5G tests and set multiple records for network speeds and performance.

The 2017 edition of TM Forum Live! is in Nice, France next week, and with the nature of telco IT-network interactions undergoing radical change, the ‘Live!’ suffix is more appropriate than ever.
NFV MANO, advanced network analytics and 5G network slice management are all hot topics with operators and vendors alike, and all play their part towards the goal of autonomous network operation.
In the same way that Mobile World Congress has steadily evolved over the years to be far more than just a mobile network event, next week’s annual TM Forum event has continued to expand. It used to be the place for ‘telco IT’ systems and carrier operation based on OSS and BSS, and if there was any direct linkage to the telecom network, it would be largely in terms of non-real time network management interactions. In fact, the nearest to ‘real time’ these network-telco IT interactions operated at was as a continuous and one-way ‘blast’ from the network to the telco IT systems delivering such things as fault reports. OSS and carrier operations staff then had to filter all these reports, prioritize them and finally decide what to do about them; that was (and largely still is) very far from real time. Now, however, everything is changing with the advent of network functions virtualization (NFV) and NFV management and orchestration (MANO). These new telco IT-network interactions must be both two-way and very close to real time for the network to remain operational at all, similar to the manner in which some modern fighter aircraft would literally fall out of the sky without automated, real-time aerodynamic trimming.

• The telco cloud requires an IP and optical core that can handle massive traffic growth and data center interconnection requirements. Huawei’s Network Cloud Engine (NCE) solution brings a cloud operational model to the network core.
• Huawei’s NetEngine 9000 (NE9000) IP core router delivers leading capacity to address massive 100G-centric connectivity requirements, from drivers such as 4K video.
This year, at Huawei’s 14th Annual Analyst Summit, affectionately referred to as HAS2017, we found a strong focus on the infrastructure layers of the network – specifically the IP core and optical core. The attention given these network layers has historically been sporadic, driven by necessary upgrades in link and/or switching capacity to keep up with growing traffic demands, a cycle that has occurred in four to eight year cycles, and further paced by technological breakthroughs. Recent industry discussion related to telco cloud seemed to be focused on network functions virtualization (NFV) in an effort to create an environment capable of supporting traditional carrier connectivity businesses and counter the threat from OTT players. However, with the arrival of web-scale providers and moves by operators to adopt a more flexible data center-centric architecture, attention is now focused on optimizing the core layers of the network.
With respect to SDN, the IP and optical domains have evolved separately, each having developed software to enable programmable control and management for the elements in their respective domains. To establish a common solution platform, Huawei introduced its Network Cloud Engine (NCE) to provide an integrated end-to-end solution for each domain, as well as provide the ability to combine multiple domains and multiple layers. In addition to the IP and optical domains, NCE includes additional solutions designed to address the access, metro and other network layers (to be covered in separate reports and blogs). Huawei has also expanded its flagship Network Engine 9000 (NE9000) core router portfolio and provided an update on its progress and new capabilities. The idea of providing a common control and management model for a multi-layer multi-level core infrastructure is not new, competitors are also pursuing similar approached to optimize the performance and efficiency of their core infrastructures.
CloudBackbone: The IP core layer, under Huawei’s NCE architecture, is controlled by the CloudBackbone solution, which includes the company’s Agile controller for IP, network service orchestration and a suite of common management functions. CloudBackbone provides support to address services such as HD video and features like automated service provisioning and network security. Also included is the ability to optimize traffic across the optical layer, which promises to deliver significantly greater bandwidth efficiency, support traffic on demand and improve provisioning efficiency.
CloudOptiX: The optical layer, under Huawei’s NCE architecture, is controlled by the CloudOptiX solution, which provides the equivalent management for the core optical transport layer as CloudBackbone does for the IP layer. CloudOptiX leverages Huawei’s Agile TSDN controller as well as common management functions and orchestration. By integrating IP + Optical, Huawei projects a 40% TCO savings through multi-layer planning and improvements in reliability with multi-layer restoration.
IP Core Advances: Along with Huawei’s NCE launch, the vendor provided an update on its flagship NetEngine 9000 (NE9000) IP core router portfolio which addresses massively scalable data center-centric interconnection (DCI) requirements, as well as traditional and emerging IP core routing functionality. The NE9000 (initially launched at HAS2015 in a 20-slot version) now includes a smaller 8-slot version, targeted to smaller core applications. Both models provide massive low latency 100G connectivity with port densities up to 400/160 per chassis, respectively. The design provides improved power/space efficiency through the use of advanced thermal techniques and expanded network programmability via Huawei’s programmable “Solar 5.0” silicon. Huawei further noted that the NE9000 is now deployed in ten service provider networks, and the NE9000-8 model will be commercially available in October 2017, along with 4 Tbps per slot line cards, to further increase capacity and density. The ability to support network slicing is also included, which enables operators to leverage one platform to support fixed, mobile and enterprise core applications.
The NCS and new NE9000 routing capacities highlighted at HAS2017, help us to remember that behind the software, is a highly capable data plane to deliver on the promise of next generation services. Capabilities such as Huawei’s NCE are well timed to support carrier transition to a DCI to cope with increased east – west traffic patterns, expected to grow >30% CAGR; support the adoption of fewer, but larger data centers, located outside of populated areas to address factors such as facility cost and power consumption; and adopt a more cloud-based operational model to automate provisioning and improve time to service. The noted capabilities also support the notion that carriers will want to manage their networks and cloud environments together, not as independent silos.
• The 2017 edition of Huawei’s Global Analyst Summit (GAS) presented the company’s “ALL CLOUD” strategic vision.
• “ALL CLOUD” goes further than most, if not all, of the company’s peers. Huawei will certainly execute but carriers will need to commit.
As is customary for the Huawei’s annual GAS, analysts are presented with a firehose of increasingly detailed information and presentations over three days. On Day 1, key executive strategy sessions kick off the show. Day 3, then, ends with one-on-one analyst briefing on specific products and services. During the three days, the company also makes every effort to show that the key themes of Day 1 cascade down into ever corner of its business.
