Overlay networking is often proposed as a means to implement an SDN architecture. By encapsulating traffic into overlay tunnels for easy transport over an IP network, overlay networking can avoid the challenges of explicitly configuring the networking infrastructure and can facilitate network virtualization and rapid connectivity between virtualized compute and storage resources. However, as carriers’ SDN strategies begin to expand beyond the data center and extend into the WAN, the need to manage the underlay network and to better coordinate the collective networking resources of the multi-layer WAN becomes critical. Overlay networking creates an opacity in the network that creates a visibility challenge to monitor SLAs and deliver differentiated services. The growth in overlay networking is creating an emerging need for carriers to engineer and control the aggregate traffic that the underlay network is transporting, ensuring maximum efficiency and utilization of resources while also ensuring QoS is maintained according to application or customer performance SLAs.
This presentation will examine the limitations of overlay networking and the key drivers for underlay networking for inter-data center WANs, particularly as the trend towards packet/optical convergence and increased flexibility within the optical transport network continues. The presentation will compare and contrast application use-cases, describe the basic capabilities the underlay network needs to enable, and detail how multi-layer SDN can help optimize inter-data center networking efficiency while ensuring proper performance SLAs for data center applications. Finally, it will explore the business benefits of enabling underlay networking as well as identify some of the key challenges in enabling SDN for inter-data center networking.

Cloud computing has dramatically changed the way telcos sell and provision compute and storage capabilities, but the network has been slow to catch up. Advancements in Software-Defined Networking (SDN) have enabled telcos to easily provision bandwidth within minutes via a customer-facing graphical user interface (GUI), enabling customers to order the bandwidth they need, when and where they need it --- as well as specify the speed, duration and quality they require. SDN-based bandwidth on-demand service can be further enhanced by providing customers the ability to order network functions such as routing, firewall, application acceleration, on demand via the same GUI. With SDN and Network Functions Virtualization (NFV) making the network less rigid and more elastic, customers are able to support unforeseen and ad hoc network resource requirements. However, this could also mean losing the ability to tie customers into annual bandwidth and traditional managed Customer Premises Equipment (CPE) contracts that provide a steady source of revenue.
This industry briefing will discuss the benefits of cloudifying your network by:
1. Supporting on-demand delivery of bandwidth and other network resources by reconfiguring your current network environment;
2. Generating new revenue streams without cannibalizing your traditional and core network revenue sources by leveraging SDN and NFV; and
3. Understanding the critical success factors that benefit and retain customers including trust and security, service usability and scalability.

Mobile operators and regulators agree that the mobile industry need for additional spectrum is real and must be addressed soon. Regulators are under pressure to make spectrum timely available for mobile network operators (MNOs) and ultimately will need to take calculated and carefully planned actions to mitigate the associated risks. Spectrum sharing can take a variety of forms and will be highly dependent on the specifics of each sharing situation between an incumbent and the MNO. Because of this inherent need for customized solutions, regulators need to avoid both micromanaging the arrangements and crafting regulations that any broad sharing would materially reduce the value of the spectrum to the MNO. Government and MNOs must craft terms that enable both parties to maximize utility of the shared spectrum. While regulators should aim to provide a light regulatory touch, the bulk of sharing negotiations should be left to the incumbents and the MNOs. Regulators, however have important roles in facilitating the sharing process by identifying sharing opportunities and facilitating band harmonization and standardization within and across countries and structuring an incentive system to reward incumbent participation.
