W h i t e Pa p e r ™ An Overview of the Optelian FLEX Architecture™ Enabling Intuitive Packet Optical Networking January 2014 Keeping up with bandwidth demand is not just a matter of boosting capacity: next generation networks also need flexibility so they can accommodate new services and applications while keeping costs low. The Optelian FLEX Architecture™ provides an adaptive, modular networking approach - delivering extensive capabilities - to address a broad range of applications and delivering the optimal foundation for service delivery. W h i t e Pa p e r Beyond the data explosion It is hardly news that today’s networks are under some fairly intense pressure. Not only do they have to handle massive data volumes, but they also need new levels of flexibility and intelligence to efficiently manage the continuous and dramatic growth. Video services The dominant driver of global IP traffic growth is video. Video already comprises more than 60% of all IP traffic today, and, when combined with peer-to-peer video distribution, is anticipated to represent as much as 90% of total Internet traffic by 2017. This includes not only streaming services, such as Netflix, Hulu and Amazon Prime, which are expected to triple in traffic, but also user generated content, business video conferencing and VoD television services. Compounding this growth is a significant increase in high definition content which is typically about four times the size of standard definition video. The emergence of video as the dominant form of IP traffic has also changed network usage patterns. Where other forms of internet traffic (eg. Web browsing or file sharing) are evenly distributed throughout the day, video more closely follows traditional television usage patterns, which are characterized by “prime-time” periods where usage spikes. In addition, the majority of this traffic is highly asymmetric, with very little upstream data. Together, these asymmetric, lumpy traffic patterns put even more stress on the underlying data networks, since network planners must plan for peak volumes. Next generation network requirements • Provide an agile and adaptive optical infrastructure • Address all service requirements with multiprotocol support and L1/L2 capabilities • Enable optimized service delivery through aggregation and deterministic performance • Ensure SONET/SDH-like high reliability and availability for equipment and services • Provide intuitive service and network management for visibility and control across all layers Cloud services Storing data in the cloud is a fairly recent trend but it is one that is expected to grow by five times to reach 36% of traffic by 2016. Analysts predict that cloud services will become a US$127B industry by 2017, driven by enterprise mobility, business continuity, and increased adoption by small and medium enterprises. Of course, storing and retrieving data from the cloud requires increased network infrastructure to handle the load and faster transfer speeds to ensure that the information is readily available. If there is a significant delay, users will revert to internal hard drives for faster access. Wireless services Mobile devices such as tablets and smartphones are proliferating at an amazing rate. In 2012, for the first time ever, more smartphones were sold than computers, driven by decreasing price points and an increase in consumer appetite for mobile web browsing, streaming video, and apps. While improved graphics and faster processors enhance the experience, increased usage is primarily facilitated by the growing availability of high speed data connections over LTE/4G and Wi-Fi networks. In fact, the average mobile connection speed in 2012 was just 526 kb/s, but is projected to rise to 3.9 Mb/s by 2017, driven by increased deployment of 4G infrastructure. Nearly 31% of mobile devices in North America will be on 4G networks by 2017 (10% globally) which will account for 45% of all mobile traffic. The rapid evolution of Internet traffic, both in terms of overall volumes of data as well as ever-changing usage trends, puts increasing emphasis on network scalability, efficiency and flexibility. Any network installed today must be capable of cost effectively delivering increased bandwidth, with the flexibility to quickly and easily accommodate the unforeseen changes in traffic patterns that are bound to emerge. The Optelian FLEX Architecture is purpose-built to meet these next generation network requirements, providing an adaptable platform that supports application innovation. An Overview of the Optelian FLEX Architecture™2 W h i t e Pa p e r Introducing the Optelian FLEX Architecture The Optelian FLEX Architecture is specifically designed to meet service provider’s next generation packet optical network requirements. Efficient, effective, and modular, it supports a wide range of solutions, from access to core, passive to packet and 100M to 100G. These include applications such as simple point-to-point architectures to full mesh networks with multi-degree ROADMs. Its scope covers the breadth of functionality of packet optical network layers 0, 1, and 2, corresponding to LightFLEX, CircuitFLEX, and PacketFLEX respectively, together with intuitive management (FLEXManager) and modular Platforms that can be configured to support any combination. It enables both pure packet or circuit-centric transport, to best suit the needs of a specific application, or a combination of both on the same platform to address the specific need of each service at each point of presence. The modular nature of the Optelian FLEX Architecture ensures optimal “first-in” costs with affordable scalability, avoiding expensive upgrades. Network operators, whether they be MSOs, wireless operators, wholesale/carriers, data center operators, utilities, research & education network operators, or any other kind of enterprise, can easily establish a solid yet cost-effective next generation network foundation, and add functionality as their business grows and evolves. PacketFLEX FLEXManager CircuitFLEX Platforms LightFLEX LightMUX FLEX Architecture - The Optelian FLEX Architecture defines the Optelian network solution and break it out into six interoperable components: • FLEXManager - intuitive SDN-based service-centric management • PacketFLEX - packet service networking and aggregation • CircuitFLEX - multi-protocol, low latency, and deterministic service delivery • LightFLEX - agile WDM networking foundation • Platforms - modular Packet Optical Transport systems • LightMUX - FTTx passive solutions The components of the FLEX Architecture integrate seamlessly to effectively deliver a complete solution that address infrastructure and service delivery applications. All together, the Optelian portfolio allows network operators to deploy, adapt and scale the network to address wavelength- and packet-based service delivery for a wide range of applications in wireless backhaul, data center interconnect, research and education, business service and residential service networks. An Overview of the Optelian FLEX Architecture™3 PacketFLEX FLEXManager Platforms CircuitFLEX FlexManager W h i t e Pa p e r LightFLEX LightMUX FLEXManager - Streamline operations with Intuitive service-centric management Operators continue to replace legacy SONET/SDH infrastructure with next generation Packet Optical systems to reduce capital expenditure and offer more flexible, value added services. As a result, creation and management of services is technology-centric and operations staff need in-depth understanding of the various technologies used to deliver services from access to core. Optelian’s FLEXManager leverages Service Driven Networking to eliminate the technology from the creation and management of services, reducing the cost and complexity of operations. Enhance visibility - FLEXManager provides a comprehensive view of the network through a graphical management interface that intuitively presents details on services, inventory, software upgrades and equipment configuration, all stored in a centralized management system. Node locations, topology awareness, port availability, connectivity status and shelf-level configuration details paint a complete picture of network operations and service connectivity. Maintain control - FLEXManager unlocks the capabilities of network solutions, simplifying provisioning and ongoing management of the network and services. The ability to manage all aspects of the network, from QoS attributes to OTN encapsulation, makes it easier to use the full set of the network’s functional capabilities and provision services for optimum performance. Respond rapidly - With a complete view of alarms, events and key performance indicators, FLEXManager enables rapid troubleshooting. Comprehensive monitoring of equipment, connectivity and services allows operators to address issues before they affect service. Key capabilities of FLEXManager • Deliver services the way they are sold • Customizable network and service details at a glance • Simplified operations with template based workflow for pre-defined service offerings • Quickly identify, troubleshoot and resolve issues on a single screen Ethernet Service Manager An Overview of the Optelian FLEX Architecture™4 PacketFLEX FLEXManager Platforms CircuitFLEX PacketFlex W h i t e Pa p e r LightFLEX LightMUX PacketFLEX - Packet service networking and aggregation with tight integration to the optical layer The PacketFLEX networking solution combines the advantages of TDM transport and packet networks. With connection-oriented service delivery, OAM, and rapid (sub-50 ms) protection switching, it provides flexible service architectures and enables the efficiency of statistical multiplexing with private and virtual service flows. Streamline delivery - Managed as integrated components, PacketFLEX service cards simplify the operation, management, and provisioning of residential, wireless backhaul, and Ethernet business services. Combining packet with optical means that single-screen management to define a service and implement end-to-end connectivity is possible which simplifies operations and speeds service time to market. Connect flexibly - PacketFLEX network cards can be connected in point-to-point, linear, mesh, and ring topologies for a suite of MEF services with both private and virtual service constructs. Full service engineering, support for high availability protection strategies, and the use of pluggable client- and line-side interfaces make PacketFLEX a flexible and adaptive solution for a diverse range of service networking needs. Software-selectable OTN line encapsulation provides extended reach and enhanced throughput where and when needed. Key capabilities of PacketFLEX • E-Line and E-LAN services with flexible bandwidth provisioning • Carrier Ethernet for scalability, service management, and resiliency • Packet-centric transport with Layer 2 aggregation and switching efficiency, and OTN line-side connections Path labels - Multiprotocol Label Switching Transport Profile (MPLS-TP) provides carrier grade transport for true layer 2 networking solutions. It allows for easier network configuration by directing data transfer between nodes based on short path labels rather than long network strings, enabling SONET-like services. This creates virtual links between nodes rather than endpoints by looking at labels rather than the content of the packet itself. Detect and recover - PacketFLEX network cards can rapidly detect, respond to and recover from network events - without affecting enduser connectivity - and do so in a manner (and timeframe) that companies are accustomed to based on previous SONET/SDH network technologies. PKX-1640 & MPX-81-EXO An Overview of the Optelian FLEX Architecture™5 PacketFLEX FLEXManager Platforms CircuitFLEX CircuitFlex W h i t e Pa p e r LightFLEX LightMUX CircuitFLEX - Multi-protocol networking with low latency bandwidth, efficient aggregation, and dynamic interconnect capabilities Many of today’s services require dedicated bandwidth with deterministic low latency, especially mission-critical services with stringent performance requirements. These networks require true Layer 1 circuits, and Optelian’s CircuitFLEX delivers them. Accommodate any protocol - CircuitFLEX offers transparent and OTN-based transponders and muxponders, accommodating any protocol at a wide range of speeds from 100M to 100G. Transponder service cards offer fully transparent, private line transmission optimized for low latency. Muxponder service cards map any service protocol into TDM or OTN circuit flows, providing a guaranteed bandwidth with network capacity efficiency, and enabling transition of legacy networks to packet services. MPX-9110 Key capabilities of CircuitFLEX • Addresses a comprehensive set of network protocols • Provides high capacity, true private line connectivity, with sub-wavelength aggregation and networking • Offers OTN wrapping on network trunk connections for error-free services with extended reach Harmonize technology - CircuitFLEX service cards offer pluggableand tunable-based interfaces, providing approaches that best meet your deployment strategy. Pluggable interfaces provide simplified sparing and allow connecting to customer equipment via any type of physical interface. These make it easy to integrate CircuitFLEX service cards into existing network systems, limiting sparing infrastructure requirements, and streamlining deployment. Boost efficiency - Lower rate wavelengths do not make effective use of available bandwidth. CircuitFLEX service cards can aggregate lower data-rate services into 10 Gb/s or 100 Gb/s wavelengths, improving spectral efficiency versus transponder-only approaches. Connect dynamically - Traditional WDM networks are limited by the point-to-point nature of wavelength connectivity, forcing service providers to deploy costly, centralized Layer 1 switch fabrics to boost efficiency and enable cross-connect capabilities. CircuitFLEX offers a modular alternative, eliminating the need to build the entire network around a TDM-only networking platform. It allows sub-wavelength services to be added, dropped or passed through nodes along linear ADM chains or around rings with OTN line-side transport. These service cards map clients efficiently to maximize line bandwidth while offering error-free services with superior reach and per-service protection capabilities. FLX-1610 An Overview of the Optelian FLEX Architecture™6 PacketFLEX FLEXManager Platforms CircuitFLEX LightFlex W h i t e Pa p e r LightFLEX LightMUX LightFLEX - A WDM network foundation that maximizes fiber capacity while providing agile wavelength connections across any network footprint Accelerating time to market while keeping costs low demands a dynamic, reconfigurable network foundation one that can scale fast and roll out new applications and services quickly. LightFLEX is specifically designed to provide the capacity, agility and reach required. Maximize capacity - LightFLEX supports up to 80 wavelengths on a single fiber pair. It supports service cards that address the full complement of protocols that are the common currency of today’s service delivery networks and can be added to incrementally as demand rises. Increase agility - ROADM elements make a network more flexible and minimize the need for pre-planning. They make it easy to add wavelengths and services, especially compared to conventional DWDM networks with fixed OADMs and banded architectures. LightFLEX stands out for its ability to deploy ROADM elements when and where they are needed instead of requiring an all-or-nothing approach, helping control capital costs. Optelian’s ROADM elements offer flexible bandwidth to support future bit rates with full-spectrum access for both 40 and 80-channel DWDM systems. Key capabilities of LightFLEX • Network scalability with CWDM, and DWDM wavelength plans • Agile network foundation empowered by multi-degree ROADM capabilities • Extensive link engineering capabilities to address diverse network footprints Scale faster - Optical channel management functionality makes it quick and easy to add wavelengths and services to a network, without extensive re-engineering or service disruption. Using sophisticated and robust control algorithms, power levels at every node are dynamically controlled for the life of the network. LightFLEX networks can be expanded and grown with no downtime or alteration to existing network segments. Reach farther - LightFLEX includes amplification capabilities to optimize reach in metro, regional, and long-haul networks. Dispersion compensation strategies address chromatic dispersion while eliminating high insertion loss, latency and non-linear degradation. Fiber Bragg Grating (FBG) compensators are compatible with coherent transceiver technology, allowing networks to support today’s common connection rates and are also 100 Gb/s ready. RDM-4100, OCM-8400 & OFA-1730 An Overview of the Optelian FLEX Architecture™7 PacketFLEX FLEXManager Platforms CircuitFLEX Platforms W h i t e Pa p e r LightFLEX LightMUX Platforms - Modular configuration capabilities for Ethernet and wavelength service delivery and WDM network infrastructure Whether it is a stand-alone solution that has integrated functionality from other layers of the FLEX Architecture in an enclosed platform, or a multi-service shelf unit that service cards are placed into, Optelian Platforms flexibly address access, aggregation, and ring interconnect deployments, a broad range of service density requirements and provide integrated management, cooling, and Optical Supervisory Channel (OSC) connectivity. Install now for future deployment - When setting up a network it often makes sense to install a shelf that will accommodate future expansion without requiring hardware changes which can temporarily shut down a network. Optelian offers a variety of shelf sizes, ranging from 1RU to 7RU for service card flexibility and optimal initial cost. Managed or Unmanaged - Depending on the network, you may need a passive optical network or a powered packet optical service delivery platform. Optelian has solutions for both deployment schemes. MPX-9110 Integrated Functionality - In addition to multi-service shelf units, Optelian also offers stand-alone managed Platforms. These units are powered and cooled with integrated management capabilities for fast network deployment to alleviate the concerns of system planning due to the flexible functionality and intuitive network management provisioning software. Key capabilities of Platforms • Platforms offer configuration flexibility and universal slot densities to address a broad range of network applications • A low ‘first-in’ cost simplifies deployment with capacity and functionality growing with network demand • Portfolio capabilities to address customer premise through core/regional networking • Options for environmentally hardened deployments OMS-7190, OMS-2190 & OMS-119 An Overview of the Optelian FLEX Architecture™8 PacketFLEX FLEXManager Platforms CircuitFLEX LightMUX W h i t e Pa p e r LightFLEX LightMUX LightMUX - Passive elements to address terminal and add-drop requirements for the full CWDM and DWDM wavelength plans Optelian’s LightMUX portfolio offers standardized passive multiplexing capabilities to address CWDM and DWDM applications. The modules provide service wavelength add/drop at Central Office (CO) facilities and along a linear path or ring for business services, FTTx connectivity, or residential broadband service distribution. Broad portfolio - LightMUX addresses the full 16-channel CWDM and 40-channel DWDM wavelength plans offering multiple options to meet any network design or passive application requirements. High availability - The components provide East/West separation which helps with ease of maintenance to distinguish between the traffic flow direction. Adjacent wavelength - Multi-channel optical add-drop multiplexers (OADMs) provide full add drop capabilities across any adjacent channels (i.e. channel 1/2, 2/3, …) to enable a flexible network structure where a subset of channels from the composite (line) in from one direction while allowing untargeted wavelengths to express through. Key capabilities of LightMUX • Addresses terminal and add-drop requirements • Supports 16-channel CWDM and 40-channel DWDM • Includes OADMs, Mux-Demux pairs, Terminal Mux-Demux and Band OADMs Flexible Packaging - Deployed using standardized packaging for easy installation and temperature hardened for outside plant deployment from -40°C to 65°C (-40°F to 149°F).
