Long anticipated, it now appears that the boundaries between fixed and mobile network infrastructure are fading. Demand for bandwidth coupled with service providers' urgent need to control costs is forcing convergence of network infrastructure, while enthusiastic adoption of wireless devices in all market segments (wireline, mobile, enterprise and consumer) is further blurring the service boundaries.
As data center providers look for ways to reduce capital expenditures, such as data center interconnect and multi-layer optimization, a new opportunity has emerged for software defined networking: transport SDN. However, transport networks face significantly different challenges than packet networks.
Network traffic growth driven by widespread adoption of smartphones, tablets, video content, and cloud computing is exploding. Service providers' revenues are not keeping pace and, thus, the cost to support the traffic growth threatens service providers' operating margins. Which providers will survive this rapidly shifting market?
U.S. broadband has reached the end of its growth phase. Now, the industry faces the challenge of shifting from building infrastructure and acquiring customers to creating sustainable business models. In a maturing market, how must operators adjust their service offerings in order to keep revenue on a growth track?
On the surface, cloud or IT infrastructure service initiatives appear to be attractive offerings for telecom service providers, but are they? Cloud or Infrastructure as a Service (IaaS) explicitly involves network services and hosting/IT infrastructure services. However, telecom operators have been slow to adopt these new services.
Though much has been said and written about SDN (software defined networking), little has been said about its business case. At a high level the board members of the Open Networking Foundation including Deutsche Telekom, Facebook, Google, and Verizon view SDN as a means to reduce their costs and increase service delivery velocity. A more detailed view of the SDN business case can be developed by digging into the cost structures of these large service providers.
Whether standalone entities or branch offices of large enterprises, medium-sized business establishments have been the neglected stepsisters of the telecom services market. Now, those businesses are moving in a major way to Carrier Ethernet services, thanks to improved quality and reliability as service providers finally overcome tough technical obstacles to delivery.
New, more sophisticated IP services are emerging, as are the associated service delivery platforms to meet the changing use and nature of the Internet. And a number of underlying trends also are driving service providers to emphasize service monetization, better network scaling, and better resource utilization in their business models. Read more
Software Defined Networking (SDN) began as a conceptual extension of data center virtualization and as such its true form has been tough to visualize. Now, as SDN use cases are being revealed on the web and in public forums, it is becoming clearer what SDN is, how it will be implemented and who will benefit or be hurt by its adoption.
Software defined networking architecture that has its origins in data center networks is a promising approach for upgrading or building out metro networks. How will SDN be integrated into the service provider's business case?
