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.
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.

Virtual EPC investments pay off for start-ups as major vendors open their wallets, filling portfolio gaps and strengthening their virtual network propositions.
Multiple vEPC wins add credibility and a level of completeness to the virtual networking solutions; customers bite and move on from PoCs and trials to commercial services.
This year’s Mobile World Congress is obviously the show to attend and at which to exhibit, and as we predicted, this is the year when the industry rapidly sets aside its safety blanket of trials and proofs of concept (PoCs) in favor of making serious commitments to virtualized solutions. Several announcements appear to demonstrate that vendors and operators have set aside pure PowerPoint and replaced it with checks from acquirers (for startups) and from operators (to vendors) for serious deployments.

For the broadband network, NETCONF deserves strong consideration for its ability to work from flexible data models (YANG) and control all devices in the service chain.
NETCONF, initially standardized in December 2006, has managed thousands of routers and switches, and it works well with SDN.
OpenFlow versions 1.4 and 1.5 appear to have the requisite functionality needed for WAN device management and control; however, although standardized in October 2013 and December 2014, respectively, vendor commitment to date appears tepid.
Since the beginning of the SDN and NFV discussion a few years back, proponents of OpenFlow have been behind the movement to control all devices in the network. This has unquestionably been the case within the confines of the data center. OpenFlow appears to solve data center issues well, even the early 1.0 version which is widely deployed, according to many sources. However, consider the many cases where, in order to provide an end-to-end WAN service or provide inter-data center connectivity, the use of OpenFlow falls short, at least until now. Continue reading “The Quest for Dominance: OpenFlow or NETCONF for Networks Outside the Data Center?”→
