NSN’s Liquid Net Picks Up Where Liquid Radio Left Off, Moving Into Backhaul and the Core | Sep 21, 2011 | Mobile Access Infrastructure | Analyst: Peter Jarich Event Summary September 20, 2011 -- Nokia Siemens Networks launched Liquid Net, umbrella solution messaging linking its Liquid Radio announcement from earlier in the year to added capacity and flexibility in the core (Liquid Core) and backhaul (Liquid Transport) networks. Core capacity flexibility is delivered thanks to core virtualization, broadband traffic management and content optimization. Backhaul efficiencies are obtained through “flexible optics, multi-layer optimization and intelligent control.” | Read Press Release | Quick Take Analytical Summary • Current Perspective: Positive on NSN’s Liquid Net launch, even if operators looking to the announcement for a deep technical understanding of how NSN plans to deliver added scalability and flexibility in the backhaul and core networks (all while tying into improved service delivery) will be disappointed. Fortunately, they can always engage with the vendor for those details. Regardless, where Liquid Radio was about supporting capacity growth and flexibility in the radio access network (RAN), Liquid Net subsumes Liquid Radio into a broader message that includes transport and core networks, promising an optimization of not only user traffic, but also CapEx investments. Perhaps most importantly, Liquid Net speaks to a need for solutions rather than point products; while components can be deployed as part of a multi-vendor solution, the combination of Liquid Radio, Liquid Core and Liquid Transport into Liquid Net speaks to holistic thinking around operator concerns and demands. • Vendor Importance: High to NSN, because similar to any wireless infrastructure vendor circa 2011, the company faces a dual imperative of matching competitor efforts at addressing burgeoning mobile data traffic while simultaneously differentiating its solutions in the marketplace. To this end, Liquid Radio was a good beginning, showcasing tools for growing RAN capacity and capacity flexibility. Liquid Net, however, is in many ways more important; core and backhaul capacity have often been painted as a mobile broadband bottleneck and the larger message helps to move NSN away from competitors which are promoting RAN improvements in isolation. • Market Impact: High on the wireless infrastructure market, because Liquid Net highlights the need to address mobile broadband traffic demands that also occur outside the RAN. Base stations will, doubtlessly, always garner more attention than the backhaul and core networks which back them up. Those networks, nevertheless, are critical components of operator CapEx and OpEx, as well as critical components in a solid user experience. While the past year has been largely dominated by wireless infrastructure vendors promoting their active antenna, cloud RAN and SON solutions, Liquid Net brings attention to broader mobile broadband solution demands and likely sets the tone for competitor marketing through next year’s Mobile World Congress.

Nokia Siemens Networks taps into future of broadband with Liquid Net

Espoo, Finland - September 20, 2011

- Radical new approach shares resources to meet unpredictable broadband demand
- Delivers services and content fluidly across the network, anywhere at any time
Nokia Siemens Networks has today launched Liquid Net, a new way to deliver broadband. Liquid Net allows an operator to set up its network to self-adapt to meet capacity and coverage requirements based on demand. The new approach also aims to significantly improve the quality of broadband services worldwide. With Liquid Net, operators can unleash the full potential of their existing business assets and create new revenue sources.

Spectacular broadband growth means networks must be ready to cope with personal data consumption of more than 1GB per mobile user per day1. Demand is also highly unpredictable, fluctuating between locations at different times as people use broadband at home, at work and on the move. Abrupt changes in broadband use can also occur when, say, new device software is launched, or updates to popular applications and over-the-top services are released, leaving operators no time to prepare.

Capacity in today’s conventional networks is typically frozen in separate places; at individual base station sites, in parts of the core network that manage voice and data services, or in the optical and IP transport networks,¡¨ said Marc Rouanne, head of Network Systems at Nokia Siemens Networks. Each is a potential bottleneck to someone getting the broadband service they want at a particular moment. Fluctuating, unpredictable demand in one part of the network means huge chunks of capacity can be left idle elsewhere, making poor use of existing investments. For example, as much as 50% of a conventional core network.s capacity can be dormant. Instead, Liquid Net unleashes frozen network capacity into a reservoir of resources that can flow to fulfill unpredictable demand, wherever and whenever people use broadband.¨

Nokia Siemens Networks has created Liquid Net2, to free-up unused capacity and allocate it instantly across the whole network wherever and whenever it is needed. Liquid Net uses automated, self-adapting broadband optimization to deliver services and content to ensure the best customer experience by always being aware of the network’s operational status and the services being consumed. In addition, Liquid Net channels traffic in the transport network along the path of least resistance and lowest cost between operator sites.

Not only does Liquid Net help operators to raise customer loyalty, but it also opens up new business opportunities. Liquid Net builds on the principles of Nokia Siemens Networks. Liquid Radio architecture3. It adds Liquid Core and Liquid Transport functionality to the network which can be implemented either separately in multi-vendor environments or in concert across an operator’s entire network to bring the full benefits of Liquid Net to bear.

Where Liquid Radio was about supporting capacity growth and flexibility in the Radio Access Network (RAN), Liquid Net smartly carries the theme forward to transport and core networks promising an optimization of not only user traffic but CAPEX investments¨, said Peter Jarich, Current Analysis, service director for Service Provider Infrastructure. “Perhaps most importantly, Liquid Net speaks to a need for solutions rather than point products; while components can be deployed as part of a multi-vendor solution, the combination of Liquid Radio, Liquid Core and Liquid Transport into Liquid Net speaks to holistic thinking around operator concerns and demands.¨

Liquid Radio, Liquid Core and Liquid Transport can be implemented together or separately in the network for fluid capacity, coverage and services at any time, which can be advantageous in multi-vendor networks. Yet by evolving the whole network, the full potential of fluid capability can be achieved. In short, the more fluid thinking that can be applied, the better,¡¨ concluded Rouanne.
