OneAccess launches OVP Design Studio for NFV

OneAccess Networks of France announced the launch of OVP Design Studio, a software tool designed to enable communication service providers and managed service providers to accelerate the creation and delivery of NFV-based services.

The new OVP Design Studio provides a graphical software tool with a 'drag and drop' design environment within which operators can model, design, test and validate complete virtual network function (VNF)-based service chains.

Once a service had been tested and validated, OVP Design Studio allows the user to export it either as an XML template or a network service descriptor (NSD) for integration into any NetConf-capable orchestration system, enabling a significant time-saving compared to current service design and deployment methods.

OVP Design Studio is designed to be used in conjunction with OneAccess' Open Virtualization Platform (OVP), a hosting platform featuring integrated vRouter for OneAccess and third-party VNFs. The solution is designed to simplify the process of creating virtual network services by quickly instantiating and interconnecting VNFs, defining the service parameters and troubleshooting the resulting service chain.

OVP Design Studio is a key element of the OneAccess OVP portfolio, which targets applications in branch offices where users wish to create virtualised deployment of on-premise services.

In October 2016, OneAccess Networks launched its OVP Linux-based middleware platform that enables lifecycle management of both OneAccess VNFs and those from third-party vendors. The platform included a drag and drop GUI that combines the NetConf, SNMP and CLI APIs in a single VNF management interface. OVP can also be bundled with OneAccess' range of white-box CPEs and VNF catalogue.

OneAccess unveiled a range of carrier-grade physical and virtual network functions designed to enable service providers to deploy NFV (network functions virtualisation) in an open and interoperable environment earlier last year. The solution includes OVP, a carrier-grade VNF catalogue and whitebox CPE.

OneAccess Outlines NFV Migration Strategy

OneAccess unveiled its service migration strategy to help Service Providers leverage virtualization technologies while taking into account their existing IT environment.

The company said its strategy emphasizes gradual NFV deployment, leveraging existing provisioning services where necessary,.  New virtualized network functions (VNFs) can in effect be activated and chained to today's legacy services. This service migration approach avoids the leap-of-faith pitfall of alternative green field approaches.

The first step of OneAccess NFV strategy is the introduction of a vCPE Adapter or virtual adapter that enables the full functions of a traditional branch-office CPE to be placed directly in the service chain of an NFV infrastructure. The vCPE Adapter enables all or part of the targeted enterprise network services to be set up using either Netconf, existing legacy protocols or a combination of both.

"Until now, operators and CSPs have been presented with two basic approaches to NFV migration," said Pravin Mirchandani, CMO and NFV evangelist."On the one hand, the big five networking vendors are saying 'Trust us. We'll get you there.' which, in effect, is a fairly transparent invitation to consolidate into inflexible vendor lock-in, something the operators desperately want to avoid. On the other hand, various Layer 2 vendors are advocating a disruptive 'rip and replace' strategy, in a bid to introduce an x86 computing platform into their customers' networks using their equipment. Neither of these approaches takes into account the need to co-exist with existing IT systems or even current upgrade plans to expand or enhance existing enterprise services."

Blueprint: NFV Needs to Get Back to (Virtual) Reality

by Pravin Mirchandani, CMO, OneAccess

Calls for ‘plausible NFV’ amid a world of short-sighted proof-of-concepts

NFV has been voraciously hyped and with good reason; there is much to get excited about. The potential benefits to operators and communication service providers (CSPs) of enabling a virtualized and service oriented network environment are vast: increased network flexibility, additional security, reductions in network OPEX/CAPEX, dynamic capacity adaptation according to network needs and, perhaps most crucial of all, reduced time to market for new, revenue generating network services that can combat declining ARPUs.  NFV really could be the silver bullet that operators and CSPs have been looking for.

Breaking Vendor Lock-in with NFV

But there’s a storm brewing for 2015. So excited has the networking industry become that its NFV gaze has focused almost universally on the end-game: an idealized world in which new services are ‘turned up’ as part of a complete virtualized service chain. Perilously little has been said about how operators will migrate to utopia from the battlegrounds of today.

To date, the central migration message coming from the big five networking vendors has been: ‘Trust us. We’ll get you there.’ Needless to say operators, whose collective future may be determined by their success with NFV, are far from comforted by such assurances. Many have endured vendor lock-in for decades and, as a result, are rightly viewing this first wave of proprietary NFV proof-of-concepts (POCs) with a healthy dose of skepticism. Given a viable and open alternative, NFV could be their chance to break free.

It’s not only vendor lock-in that operators should fear. In their haste to establish NFV dominance, many vendors have NFV-ized their existing lines of routers and switches by installing x86 cards and are now conducting operator POCs via this generic computing environment. This is sledgehammer NFV in action; it may prove that the theory behind NFV is possible, but it is seriously lacking in plausibility when any kind of scaled migration path is considered.

Cash-strapped operators are highly unlikely to stomach the significant price premium required to install x86 cards across their entire CPE infrastructure. Moreover, x86 does not always deliver the optimized performance needed for the volume packet handling and SLA requirements for today’s network services, and in the operators’ last-mile network, there are far too many access link combinations required to enable the physical hardware to be done away with any time soon. ADSL, VDSL, S.HDSL, among others, plus cellular for radio access (frequently used for backup), together with SFP ports to support different fiber speeds and optical standards, are not readily available in an x86 platform, and could only be made so at a prohibitive cost.

Operators Should Focus on Virtual Network Functions (VNFs)

Most importantly, however, is the need for operators to focus on the services, or virtual network functions (VNFs), that they wish to deliver. Today (over their legacy infrastructures) operators are just starting to introduce bundles of managed network services to enterprise customers and are generating much needed revenues as a result. In cash terms, the most valuable of these services (VPN encryption, application performance management and WAN optimization, are good examples) rely on intelligence being present at the edge of the network, as well as in the core. Locating ‘dual-headed’ functions such as these on the router itself makes by far the most sense, but will be a huge technical challenge to achieve via an x86 card.

Operators may go to sleep dreaming of a fully functioning virtualized infrastructure, but the tough truth is that they’re not going to wake up to one any time soon. Theirs is a world where every cent of network investment must be pegged against immediate performance gains. The slim budgets which do exist are focused on network imperatives, like tackling legacy infrastructure obsolescence and reducing TCO.

For operators to commit to NFV beyond today’s POCs, they will need a staged, scalable and flexible migration strategy, which neither increases costs nor diverts budgets away from more immediate priorities. They also need managed migration. This means the ability to ‘activate’ VNFs only when they are ready to do so, otherwise the money simply won’t be spent. It’s high time that the vendor community understood this and adjusted their management of these customers accordingly.

With this in mind, OneAccess has spent the last three years preparing its product portfolio to address precisely these issues. While the big five have vied for influence in NFV, scrapping over ‘who leads the market’, OneAccess has been doing the heavy lifting. It has successfully separated the hardware-dependent forwarding plane from the ripe-for-virtualization control plane in its CPE routers and integrated the tail-f management framework; something that no other CPE vendor has accomplished.

As a result, it can now enable both the virtualized management of each router and support the continued delivery of today’s legacy services as well as support dual-headed functions as VNFs.  And finally, because OneAccess is an operator service-enablement specialist, its router platforms are purpose designed for this environment which, in the context of NFV, means they are open. Not only does this guarantee interoperability with each operator’s existing infrastructure, it also hands them a skeleton key which they can use to force the bigger vendors to follow suit.

As we move into 2015, fever-pitch excitement over all things NFV will subside and the serious business of service migration will take center stage. For the sake of the operators, vendors in the networking industry can’t get back to (virtual) reality soon enough.
