As Principal Analyst of Transport and Routing Infrastructure, Glen analyzes technology, product, and partnership initiatives of vendors who supply carrier infrastructure equipment. Specifically, focusing on vendors that produce core routers, edge switching, optical transport, data center interconnection, mobile backhaul, network management and operational support systems.
• 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.

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 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.
Increased east-west server-to-server data center traffic leaves traditional perimeter defense mechanisms challenged to provide adequate trust and privileges for virtual machines (VMs) while current zero-trust mechanisms consume valuable server resources.
Netronome’s new Agilio CX intelligent server adapter promises to deliver 25 Gbps of throughput; integration with Open vSwitch firewall and Mirantis OpenStack delivers the benefits of hardware acceleration and improved VM performance.
At the August 2016 OpenStack Summit, Netronome announced enhancements to its Agilio Server Networking Platform with the introduction of the Agilio CX dual-port 25GbE intelligent server adapter (ISA) and Agilio OVS Firewall software. The new platform is integrated with the Mirantis OpenStack solution, with the goal of easing cloud-based provisioning, and promises to improve performance and scale when implementing Linux Firewall-based as well as zero-trust security using OpenStack security groups. As service providers migrate their infrastructures to a data center model to meet growing demands for cloud-based services, issues such as scale and security increase ever more.

• Supports Both VM and Container Stacks: Cloudify 3.4 simultaneously supports VM stacks, container stacks and hybrid stacks; providing support for current VM deployments while migrating to more efficient container-based solutions.
• Leverages Open Source Innovation: Cloudify 3.4 leverages open source innovations such as Kubernetes technology, which helps support distributed container-based applications and deliver the hybrid stack capabilities.
The new Cloudify 3.4 release from GigaSpaces removes significant deployment barriers for service providers (and enterprises) that are considering migrating their virtualization architectures from a virtual machine (VM)-based model to a more streamlined and efficient container-based architecture to support microservices. The merits of this transition are covered well in many industry blogs and reports and will not be the focus here. However, what’s new is that this new version of Cloudify supports both environments (VM and container) as well as a combination of the two (hybrid). This is an important capability, because as the industry moves beyond simply proving the basics of network virtualization, traditional service provider strengths such as performance, scalability and efficiency move front and center. Cloudify 3.4 promises to support current implementations while enabling new applications to be container-based, thereby providing users a flexible migration path to the future. In addition to the dual-stack support, the new release supports fully automated “in-place” infrastructure upgrades, which helps to minimize down-time and eases migration to new software versions without impacting on-going services.
Operators seeking new revenue opportunities find SD-WAN a lucrative addition to their traditional enterprise service offering; enterprises like the idea of more transport choices and on-demand services.
Juniper is expanding its Cloud-Enabled Branch CPE solution by adding incremental SD-WAN support based on its virtual SRX, to deliver scalable and secure networking features.
Juniper joins its competitors in offering an SD-WAN solution. There is little doubt regarding service provider interest in delivering new, more agile WAN services, and even less doubt that enterprises will also see the benefits. Given today’s desire to have everything on demand, enterprises like the concept of controlling their networks from a central location and moving bandwidth and connectivity around based on real-time business needs. So, what is needed to deliver a compelling SD-WAN solution? It has already been established that virtual customer premises equipment (vCPE) solutions address many of these requirements. As described in Juniper’s earlier Cloud CPE launch, vCPE promises to enable operators to create and automatically deploy services faster, at industry-leading scale, in on-premises, cloud or hybrid service delivery models.

• CE 2.0 certified services form the foundation for “Third Network” connectivity services, enabled by emerging Lifecycle Service Orchestration (LSO), SDN, and NFV technology solutions.
• Some 55 service providers, to date, have earned CE 2.0 service certification, with 16 added in 2015, showing that aside from the march to SDN/NFV utopia, fundamental service delivery remains king.
Using the MEF’s upcoming Gen15 networking event in Dallas as a backdrop, it is obvious that vendors and operators alike continue to see the merits of obtaining CE 2.0 service certification in order to deliver on fundamental Ethernet services. Not only are vendors and operators spending the resources necessary to obtain certification, but they are also actively engaged in the upcoming Gen15 event. During 2015, trials and PoCs involving NFV and SDN are clearly moving to the very real beginnings of deployment – this is where the value of CE 2.0 really begins to shine. Not only can operators continue to offer an industry standard set of Ethernet services (E-LAN, E-Line, E-Tree and E-Access), but now with the added agility that is promised by NFV implementations (e.g., CE 2.0 as a virtual network function [VNF]), and with broad industry cooperation, customers can also expect that these more dynamic services will continue to be interoperable across vendor platforms and across multiple operators.

Uses ICONA, an application developed on top of ONOS, to extend its capabilities to support intra-domain sessions which leverage BGP to established router-to-router connectivity.
Uses an ONOS SDN-IP peering application hosted on Americas Lightpaths (AmLight), creating SDN facility based on OpenFlow which interconnects five Latin American research and education networks (RENs).
ONOS continues to gain exposure and provide an effective platform for researchers and network developers to continue to evolve SDN-based solutions and help the industry transform from closed vendor-specific network devices to those using open software and COTS hardware. First, ON.Lab announced, in concert with GEANT, an ONOS deployment in a pan-European network that interconnects Europe’s national research and education networks; a second announcement, in concert with Florida International University, involved deployment to interconnect five Latin American RENs. Both announcements provide valid proof points to support the goal established by ON.Lab, which is to create a carrier-grade platform to host critical network applications using open source software.

Virtual EPCs (vEPC) begin to see commercial application, but PoCs and trials still outweigh deployments by a wide margin.
Operators appear to be sampling the wares of multiple vendors before taking the plunge – small and larger vendors claim significant operator interest in their solutions.
Current Analysis recently updated its mid-year assessments of the products of the six primary mobile core vendors, all of which continue to add enhancements to their traditional physical EPC solutions; but over the past period they have also expanded their virtual EPC (vEPC) offers and note considerable traction (albeit mostly on the trial and PoC front) with operators from all geographies. This is only natural since the promise of network virtualization, if only partly realized, could significantly change network architectures, benefiting both consumers and operators.

ODL’s third release (Lithium) appears to close the gaps from earlier versions, such as testing, performance, native support of OpenStack Neutron and broader community participation.
ONOS logs its first commercial/production deployment since its release in December 2014. It should mark the beginning of many more, as it touts the carrier-grade characteristics needed to run live traffic.
Why is the OpenDaylight (ODL) Lithium release (its third) an important step in the evolution of the controller? Although the details are many, several features stand out as being important for adoption in a service provider environment. These features include support for: quality of service data, because RestAPIs are more robust in the data identification process; service chaining, to provide the infrastructure needed to provision a service chain and provide the end-user application for defining it; rigorous testing, to characterize multiple use cases to help boost scalability and performance; and better support of security and automation, because with most network functions going virtual, the need for a security architecture becomes more critical, and the ability to automate functions to minimize human errors and improve productivity helps operators reduce the risk of security breaches while reducing overall operational expenses.
