IHS MARKIT TECHNOLOGY Solving the DAA Capacity Crunch with Packet Optical Transport The combination of fiber-deep and Distributed Access Architectures (DAA) is driving a new investment cycle in cable operator aggregation and metro networks, opening up a significant new opportunity for cable network-optimized wavelength-division multiplexing transport solutions. This paper explores the impact of DAA on cable access network infrastructure and the resulting opportunity for coherent packet-optical transport solutions in support of this transition.
Infinera Unveils ICE5 Next-Generation Optical Engine Infinera continues to build upon its strong heritage and deep experience in photonic integration. In 2017, the company delivered the 1.2 Tb/s Infinite Capacity Engine (ICE4) with the fourth-generation PIC and FlexCoherent DSP. ICE4 supports up to six, 200Gb/s per wavelengths with super-channel support for up to 1.2 Tb/s. ICE4 technology is broadly deployed across the Infinera product portfolio, including the Cloud Xpress 2, XT/XTS-3300 meshponder and the flagship DTN-X XTC series.The 2.4 Tb/s ICE5 triples per-wavelength capacity, supporting up to four 600 Gb/s wavelengths and doubles the capacity of the ICE4 engine.
ACG Market Impact Report: Instant Network Infinera, a company long known for its industry-leading photonic integration, is taking another step in its journey toward cognitive networking with the introduction of Infinera Instant Network. Infinera Instant Network builds upon three of the company's foundational technologies: fourth-generation sliceable, multi-terabit, photonic integration; open, programmable network interfaces with the Xceed SDN Software Suite and Instant Bandwidth software activation of service-ready optical capacity.
Infinera Delivers the Xceed Software Suite Infinera’s Xceed Software Suite delivers dynamic service applications over an open source SDN controller with advanced multi-layer path computation and a rich network abstraction layer. Xceed’s automated and programmatic approach helps service providers achieve profitable growth by maximizing multi-layer networking efficiency and minimizing operational costs.
Infinera Delivers Instant Bandwidth - An ACG Market Impact Report Infinera’s Instant Bandwidth™ offering will enable it to expand its customer base by offering options to operators that may not have been able to purchase 500G or do not need 500G right away.
Keep in mind that operators are building entire networks, and 500G of bandwidth will be the required capacity for many network routes when doing an upgrade. Yet, offering it in 100G increments still retains the benefits of integrated OTN switching and super-channels with excellent PMD compensation and enables routes to be deployed at increasing distances with lower impairments.
This option closely coupled with network capacity deployment and customer service requirements delivers real cost savings.
Looking forward, we expect this software- and hardware-based instant bandwidth utility model will enable Infinera to widen its potential market base and increase its global market share in 2013 and 2014.
Architecting the New Metro Network for the Cloud Era Metro networks are entering a period of profound change and disruption driven not only by the continued growth in metro IP traffic but, even more significantly, by the changing demands and requirements for network services driven by the cloud. The gap between the flexible and on-demand requirements of cloud applications and the static nature of today’s metro networks is unprecedented, and is leading network operators globally to radically re-think how networks are built and operated. In short, cloud services (Layer C) are the business drivers for metro network transformation, part of the intelligent transport (Layer T). While NFV will ultimately drive the virtualization of hundreds of network functions, not all functions will be virtualized. The job of the next generation metro transport network will be to combine state-of-the-art photonic innovations with the right mix of packet switching in order to support Layer C. Heavy Reading outlines the key building blocks for next generation metro networks in this whitepaper.
The New Simplified Network Model Rapid network traffic growth is driving constant change in the infrastructure as operators strive to scale their networks to keep up with the growth. In addition to the capital expense of this infrastructure expansion, the network is becoming more complex, which has led operators to employ the IT tool of virtualization, in the form of network functions virtualization (NFV), to reduce network complexity. NFV is becoming a reality in the network as equipment designers have virtualized numerous network elements such as the firewall, evolved packet core (EPC) and provider edge (PE) router. As virtualization subsumes many functions that modify services and connections which were otherwise performed in physical network elements, vendors are freed to develop network elements that are focused on moving bits and/or packets (which cannot be virtualized), and not performing ancillary network functions. This segregation of network functions into virtual versus physical processes suggests a two-layer model, which can simplify network planning and result in a more effective and efficient network.
100G+ and ROADM Strategies: Global Service Provider Survey Deployment of 100G WDM ports tripled in 2013 and continues to grow rapidly through 2014. But by 2016 deployment of this technology in core networks saturates— and then the opportunity for coherent WDM technology at rates for 100G and beyond really lies in the shorter spans of the metro. We discovered that the killer app for metro 100G in the next 12 months is data center interconnect (DCI).
Rise of High-Capacity Data Center Interconnect in Hyper-Scale Service Provider Systems The growth of cloud-based services in consumer and business applications during the past five years has been spectacular. Projections are that this trajectory will continue during the next five years. By 2019 mobile network traffic is forecasted to increase tenfold. Half of this increase will be in video services, and an additional 10 percent will be in social networking applications. At the same time, business cloud computing services are expected to increase at a 40 percent average annual rate. By 2019 there will be 60 percent more data centers in the world’s metropolitan areas than there are today, and data center interconnect volumes will increase by more than 400 percent.
ICT Core Networks: Towards a Scalable, Energy Efficient Future 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.
