Nokia Siemens Networks has launched a new way to deliver broadband, Liquid Net. The Liquid Net system allows an operator to set up its network to self-adapt to meet capacity and coverage requirements based on demand. The new approach is aimed at improving the quality of broadband services delivered worldwide.
The sudden surge in demand for real broadband means networks must be ready to cope with personal data consumption of more than 1GB per mobile user per day. Broadband demand has also become 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.”
Liquid Net 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.
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.
