Keeping up with Data Centre Interconnect
Stu Elby, senior vice president of cloud network strategy and technology at Infinera, discusses the growing demand for inter-data centre traffic and the efficient solutions which should respond to this challenge.
TUESDAY 03 March, 2015
“…In the early days of cloud, the same equipment was used for both Data Centre Interconnect and end-user traffic. However, with the rise of social media and machine-to-machine communication, bandwidth requirements across DCI have taken off and require a new class of equipment.
With this shift in speed and demand for terabits, operators cannot provide a solution that chews up half a rack of equipment and requires a kilowatt of power – that model simply would not fit into a data centre real estate or energy profile…
At Infinera we have attacked this challenge by applying our photonic integrated circuit technology which allows us to achieve very efficient power and space profiles – the purpose-built Cloud Xpress box…”

MRV joins the ONF, focuses on SDN and NFV
MRV Communications(TM), Inc. (OTCQB: MRVC) (“MRV(R)”), a leading provider of innovative packet and optical solutions, today announced it has joined the Open Networking Foundation (ONF) and is participating in the European Telecommunications Standards Institute’s (ETSI) Network Functions Virtualization (NFV) Industry Specification Group. MRV will bring over 25 years’ expertise in packet and optical networking to the standards bodies. Together they will focus on leveraging software and virtualization to architect innovative, next-generation networks. The company’s participation reflects its strategic roadmap towards network virtualization and software-driven services that will help carriers, data centers and content delivery providers achieve a more intelligent network, reduce OPEX and deliver high-value, revenue-generating services easier and faster.
“MRV is a trusted partner in the access and metro networks, and through long-standing customer relationships, we have gained a deep understanding of what it takes to create better, more open networks,” said Edna Ganon, director of technology, MRV Communications. “With virtualization of the metro network providing the next step for optimum network usage and dynamic behavior, collaboration within the industry is key to delivering exactly what the market needs. We look forward to working with our colleagues in the ONF and ETSI communities on bringing interoperability and standardization to the next generation of software-based networks.”
Many networks today are not optimized to support the rise in demand for cloud and mobility services, or the bandwidth-rich content that comes with them. Networks must evolve in order to keep up with exponential traffic growth and new traffic patterns. Much of this evolution will occur at the access and metro levels, where most of the transactions take place and individual services are created. Software-Defined Networking (SDN) and NFV approaches will help in this process as they look to streamline network operations so advanced services are easier to manage and providers can more easily meet high service levels. The NFV initiative–lead by ETSI–is focused on using virtualization to decrease the amount of proprietary hardware needed to launch and operate services. SDN is an approach lead by ONF in which network control is decoupled from hardware and moved to a software-based controller.
“ONF is a user-driven organization, that brings consumers and suppliers of SDN technology together to address real-world networking challenges in markets that include data centers, metro networks, and wide area networks,” said Dan Pitt, executive director, Open Networking Foundation. “The collaboration between these leading global companies is critical for enabling extremely dynamic, manageable and cost-effective architectures. These standards will ensure better integration and interoperability throughout the SDN ecosystem and accelerate the delivery of SDN benefits to today’s operators and enterprises.”

TRANSPACKET H1; a fusion networking add-drop muxponder
TransPacket addresses the increasing demand for high capacity and high quality optical network transport services, dynamic networking and management simplicity. TransPacket?s unique and patented Fusion Networking allows wavelength-grade Quality of Service (QoS): Ultra-low latency, ultra-low latency variation and zero packet loss, enabling transparent transport of e.g. synchronization information (IEEE1588) and high-quality video. Additionally, the high capacity utilization known from packet switching is achieved using statistical multiplexing on top of the circuits. Through combining circuit switching of packets and packet switching of packets within a single wavelength and without using time-slots, fusion networks combines the best properties of circuit and packet switching in a unique way.
Addressable markets and applications
Mobile backhaul
TransPacket H1 features important functionalities for mobile-backhaul. Ultra-low latency variation enables synchronization through transparent tunneling of IEEE1588 packets. Additionally, H1 supports SyncE (G.8262). Ultra-low latency and latency variation, as well as zero packet loss enable transport of QoS-demanding services, while statistically multiplexed packet transport at the same time, enables efficient utilization of resources in the network.
Metro network
A Metro network should be able to transport and aggregate traffic from a diverse type of services like e.g. mobile services, gigabit lines from business customers, aggregated traffic from DSLAM?s, High-quality video traffic for broadcasters, etc. The unique TransPacket fusion technology enables easy transport of all these services within a single wavelength. The Add/drop functionality of H1 allows aggregation and redundancy in a ring-network structure. Furthermore, the deep buffering of H1 enables efficient statistical multiplexed aggregation.
Efficient and secure business access
TransPacket H1 enables transparent transport of traffic from business customers. Fusion networking allows isolation between business customers, increasing security, performance and availability. Furthermore, a centralized approach for controlling the services increases simplicity, reducing OPEX. The H1 meets a set of requirements within the business segment, such as low latency, transparent transport layer, ease of operation and maintenance, rack space limitations, dual redundant power feeds, low power consumption and pluggable optics. It serves the growing bandwidth and QoS demands for numerous business applications through wavelength grade QoS and transparent GE lines along with optical diagnostic and protection capabilities. The unit comes with complete performance monitoring, and can be integrated in your existing management systems using CLI, SNMP, RMON and Netconf management.

Fibre Management and Its Role in Cloud Computing
Memoriesare life’s most prized possession. And because of that I go to great lengths toensure they are protected against what would be a disaster if I lost them all.Besides my iMac, I store to a router/backup on a regular schedule. I also backup monthly to a portable hard drive that should be kept off site but for now isin the house. Music is further backed up (with some tricks) on what seems likea dozen iPods among the family. I also save to storage in the cloud using asubscribed service. The cloud is my absolute failsafe should all other measuresfail. I have entrusted all my data and assets to reside somewhere out there inthe cloud and in the data centers of the world. And they are doing everythingthey can to protect them, right?

arcutronix supports the quality rating of LTE infrastructure
The 4th generation mobile technique LTE(Long Term Evolution) is demanding much higher requirements on clocking andsynchronisation as with former technologies. Even more, the back-hauling of theantennas for LTE (eNodeB) is purely based on Ethernet, which did not offerspecial features for clock and synchrony up to now. Ethernet is normally anasynchronous and packet-oriented transmission technology mainly used in LAN.Due to that there was no need to fulfil any demands on these quality featuresand in regular products nothing was prepared to support them.
Understanding the newdemands of back-hauling antennas via Ethernet, arcutronix implements in itsaccess devices synchronous Ethernet (Sync-E) and PTP.
Sync-E works onphysical layer similar to SDH. The Precision-Time Protocol, defined by IEEErecommendation 1588v2-2008, is a packet-based method to synchronise clocks andis independent to the physical transport, which is a big difference to Sync-E.Using Master-Slave architecture, the timing source (Grandmaster) sendsperiodically packets, which are carrying the actual time/clock. In amulti-stage procedure, each attached slave determines the packet-delay betweenitself and the Grandmaster. Knowing this individual packet-delay the slave canadjust its clock correctly. The algorithm used to calculate the delay of thetiming-packets requires precise timestamps for the sending and receiving time.Depending on the quality of the timestamps, the slave’s established clock canbe the same as on the Grandmaster, varying only a few Nano-seconds.
As for all packet-oriented procedures, thereare variations in the packet-delay for PTP packets and so the value is notconstant, but slightly fluctuating. The smaller the packet-delay variation, thebetter is the result for the calculated clock at the PTP slave. In addition,any change in the topology of the network, caused by failure of lines or nodes,will lead to massive change in the mean-packet-delay between Grandmaster andslave.
The calculation of the packet-delay betweenslave and Grandmaster plus the optimisation of the network to smallpacket-delay variations is one of the big challenges for operators andproviders. The used network models are never matching to existing lines. Theycan only be seen as a generalisation of common known networks.
arcutronix offers in its products the optionto log the calculated packet-delays and to store this over a long period oftime (up to 3 years). Using these loggings, conclusions about the network canbe done and ways for corrections can be found. Any changes in the topology canbe back-tracked and the influence on the quality-level of the PTP. So this newfeature is not only a mighty tool for operators but also very well suited intest cases and to improve further models of existing topologies.
