New carrier ethernet solutions to drive 4G evolution

Ciena Corporation have announced the expansion of its Carrier Ethernet Service Delivery (CESD) portfolio with the addition of new switching products designed to
address LTE backhaul networking requirements.

EthernetFeaturing flexible connectivity options and traffic type awareness, the new platforms empower service providers to meet the rapidly growing demand for data services
with speed, scalability and resiliency, while reducing network complexity and lowering operating costs.

Market Background:

It is widely accepted that the proliferation of next generation mobile devices and associated data applications is forcing network operators to invest in additional capacity and move to 4G technologies to accommodate growth and support new service demands.

To do that, service providers are increasingly turning to high speed, low latency LTE technologies that improve network performance and lower operating costs while
supporting the need for additional bandwidth all within their existing spectrum. As a result, however, operators are facing more pressure on the critical wireless backhaul portion of the network that ensures the traffic flows between cell towers and the terrestrial core network.

When planning the migration to 4G, service providers must ensure their backhaul networks contain these three design attributes, scalability to ensure rapid response to evolving bandwidth needs, partially driven by an increase of IP-connected devices.

Ciena’s Approach:

By deploying Ciena’s Carrier Ethernet solutions for LTE wireless backhaul, wholesale capacity suppliers and mobile network operators can realize up to 30 per cent savings in capital expenses and up to 80 per cent reduction in turn up times at a base stations as compared to alternative packet technologies.

Ciena’s portfolio offers a number of architectural advantages, including, sophisticated network resource provisioning and optimization to more efficiently control, manage and monetize unpredictable traffic over the network, MEF compliant Carrier Ethernet based infrastructure options for network access, coupled with scalable, converged optical Ethernet solutions to simplify transport in aggregation or metro core networks and configure the backhaul network to be transparent to the wireless layer’s IP protocols, a common service aware operating system to address a multitude of backhaul scenarios depending on the availability of fiber, the degree of multi tenancy, and various generations of radio base stations for greater cost and resource savings.
