- Special Report: TSIC uses DTN-X to Differentiate [93 KB]
TeliaSonera International Carrier (TSIC), the wholesale arm of TeliaSonera Group, provides a good case study of how global carriers are using 100G-optimized optical infrastructure to support new or expanded business models. Using Infinera's 500G-based DTN-X to underpin its business strategy, TSIC is equipped to attack its long-term goal to become the global leader in wholesale services. TSIC's business helped Infinera ascend to and strengthen its position as the leader in annualized 100G sales in North America.
- ICT Core Networks: Towards a Scalable, Energy Efficient Future -- The Institute for Energy Efficiency, UC Santa Barbara Report [1.1 MB]
The past 15 years have been a time of tremendous growth in the availability and fidelity of communication technologies. Pervasive availability and the growing richness of content have resulted in exponential growth of communications traffic related to Internet, multimedia, and cloud computing applications and services. The combined efforts of industry, government, academia, and investors have kept pace with this demand, but the growing cost, heat, and energy requirements challenge the scalability and energy efficiency of future networks.

The results show a stronger preference for OTN switching in general and greater emphasis on integrating OTN switching with WDM interfaces in the same hardware platform. By 2016, 94% of respondents who plan to use OTN switching in the core want WDM interfaces integrated in the OTN switching equipment.
- 100G & Beyond: Preparing for the Terabit Era -- A Heavy Reading Report [1 MB]
100G transport is a great industry success story, and one that Light Reading and Heavy Reading have been tracking since the technology's inception. In our January 2012 100G Industry Initiative white paper "Deploying 100G Transport Networks Today," we made the case that, following years of development and trial activity, 100G had "arrived" and the stage was set for wide-scale adoption to begin. Looking back on last year, we can say that our assessment was on the mark and that commercial adoption is actually exceeding our expectations. There are well over 170 commercial 100G wins to date, all over the world.
- ACG Research analyzes business case for Shared Mesh Protection -- ACG Market Impact Report [809 KB]
Current approaches to network resiliency are inadequate to meet evolving network performance and cost requirements. Existing schemes such as 1+1 protection meet the sub 50 ms performance requirement but only protect against single failures and are too costly. Best-effort approaches such as software-based GMPLS mesh restoration are cost effective, handle multiple failures but do not meet the sub 50 ms performance requirement. MPLS FRR can protect against multiple failures and achieve local 50 ms performance but requires longer time frames for end-to-end convergence and uses more costly router ports.
- Transport Software Defined Networking: Part 1: Grabbing the Low-Hanging Fruit -- A Current Analysis Report [131 KB]
In October 2012, network operators and vendors gathered with software-defined networking (SDN) developers and academics in Darmstadt, Germany, at the SDN & OpenFlow World Congress to give the SDN community a voice to share its thoughts and provide some structure to what has become a broad, and in many ways, unstructured, debate. This was the first SDN conference to draw heavy service provider participation, so it provided a stage on which operators and vendors could address what SDN should (or could) mean for service providers.
- Virtualized Optical Networks via OTN -- An Infonetics Research, Inc Report [2.5 MB]
Virtualization is the practice of abstracting a pool of common resources for use by multiple services--virtualization has revolutionized computing in enterprise and large datacenter applications. Virtual machines (VMs) in the data center allowed computing resources (hardware) to be decoupled from applications/services, improving hardware utilization and efficiency to save capex. VMs also reduce opex by bringing centralized management of these hardware resources and services. Services with different priorities cab be quickly shifted and cloned on top of a homogenous hardware resource pool.
- CenturyLink Deploys Infinera's DTN-X -- A Heavy Reading Paper [141 KB]
Infinera has announced that CenturyLink has deployed the Infinera DTN-X system on its nationwide fiber-optic backbone. The deployment was announced today in a brief press release that states that the DTN-X 100G backbone will support video, mobile and cloud services as well as extend the operator's ability to deliver services up to 100-Gigabit Ethernet to its own data centers and customer facilities nationwide. No contract value was announced.
- Infinera Delivers Instant Bandwidth - An ACG Market Impact Report -- ACG Market Impact Report [376 KB]
Operators are focused on accelerating service delivery, because the faster you deliver a service, the faster you recognize revenue and win more deals. Once revenue is recognized, an operator can then up-sell on that service as well as bundle it for additional revenue.
Today, the service delivery for bandwidth is fairly slow: an order passes through planning; is handed to procurement; then equipment must be delivered, installed and activated. This process typically takes eight weeks or more and may vary geographically; it could be much longer in other regions. This lengthy process contributes to cash flow management issues, delays revenue and impacts an operator's competitive position. If another competitor can deliver services faster, the operator may lose the business. Shortening the duration of service deployment and the operational cycle at nodes decreases the number of steps when adding bandwidth to the network. Infinera has announced an innovative solution that enables a just-in-time link between the customers' business processes and their operational procedures. This model provides by a simple software command a large, flexible pool of "instant bandwidth" that is available in 100G slices. It shortens the service cycle from eight weeks to minutes, enabling better cash management and delivering a significant competitive advantage.
- The Benefits of Photonic Integration in Next-Gen Transport & Switching Systems -- A Heavy Reading Paper [532 KB]
For years, core networks received little attention while operators focused their
investments on upgrading their metro core, aggregation and access networks to
deal with IP traffic growth and new services on both the wireline and wireless side. Over the past couple years, however, we have seen a core network renaissance begin. With upgrades in metro and access networks complete, operators are finding that the core network has become the bottleneck. As operators invest in the next round of core networks, they will take advantage of the latest technologies available in order to squeeze the greatest efficiencies out of their finite bandwidth and to future-proof their networks against continued traffic growth. The first move in this direction is being seen as super-channel line card implementations beginning to address the emerging 100G market, and competing directly with non-integrated implementations of 100G.
- Super-Channels: The Next Optical Frontier -- An ACG Market Impact Report [392 KB]
Operators and content providers are experiencing increasing demand for core network capacity, driven by video distribution and data center connectivity. Traditional service providers have estimated that traffic will grow at a conservative rate of 40 percent a year; content providers see an even higher rate. Because of this growth, transport network resources face constraints as 100G wavelengths are increasingly being deployed to enable more bandwidth for these applications.
