Cyta Hellas, a wholly owned subsidiary of the National Telecommunications Organization of Cyprus, is the latest network operator to deploy Cisco’s Dense Wavelength Division Multiplexing (DWDM) transport solution for a new high-speed backbone. Cyta is the most recent service provider to be licensed in Greece, which is part of the mother company’s effort to expand to new markets. In almost six years, Cyta has achieved nearly 17% market share and is still growing, despite challenging economic conditions. Today, the company operates a network of over 5,000 km one of the largest privately owned fiber optic networks in Greece.

Cloud consumption models are gaining traction across all company sizes and industries. Whether software as a service (SaaS), infrastructure as a service (IaaS), or platform as a service (PaaS), the value propositions of virtualization are being sought by IT decision makers.
Cisco Consulting Services sees an opportunity for network service providers (SPs) to deliver a similar experience through a new solution architecture that we call network as a service (NaaS). NaaS does for the network what SaaS and IaaS have done for the data center — offering many of the same value proposition components, such as lower OpEx and increased agility, as well as new business model levers and distribution benefits.
A Simple NaaS Architecture Delivers Broad Benefits
To illustrate the value, this paper focuses on NaaS for mobile operators, although similar value could be articulated across all SP segments. Today, the various engineering and operational functions required to enable new customers, new services, and repairs are buried behind monolithic and independent network elements. The goal of NaaS is to simplify the architecture through virtualization, bringing disparate software solutions onto common hardware.
At the heart of mobile NaaS is an intelligent core with the service elements needed to deploy mobile data services (Figure 1). Traditionally, each software element runs on dedicated hardware, but under NaaS, these elements are separated so the software can run on shared virtual machines. The model also includes a common storage and compute infrastructure that can be delivered to the intelligent core as needed through a virtual machine approach. The intelligent core should work across a variety of licensed and unlicensed access technologies, shown at right. The active service catalog represents the SP’s ability to create unique service environments by combining service elements in an automated and simplified way. Finally, the secure portal enables consumers and business customers to access and manage their own network instances.

Since its founding in 1999, Cbeyond, the Atlanta-based managed services provider, has tried to remain true to its name. The company which focuses exclusively on small- and medium-sized businesses must observe and act on technology trends well in advance to maintain its position with its customers as both a communications and hosted IT provider.
We recently had an opportunity to interview Brent Cobb, Cbeyond’s Chief Revenue and Customer Officer to hear how Cbeyond enables its small business customers to reap the benefits of advanced technology usually unavailable without the IT infrastructure of a big business.
