Mid-Atlantic Crossroads Tests 400/800G Optical Transport with Fujitsu

Mid-Atlantic Crossroads (MAX), which is is a multi-state research network led by the University of Maryland, has successfully tested 400G and 800G optical transport in partnership with Fujitsu Network Communications.

The trial, which was conducted over a live network route from Baltimore to McLean, Virginia, carried 400 Gbps and 800 Gbps transmissions alongside the existing 10 Gbps and 100 Gbps channels using the Fujitsu FLASHWAVE 9500 Packet Optical Networking Platform (Packet ONP).

Channel spacing was reduced 25% over conventional dense wavelength division multiplexing (DWDM). The trial employed advanced modulation techniques, including dual-polarization quadrature phase shift keying (DP-QPSK) and dual-polarization 16-ary quadrature amplitude modulation (DP-16QAM), yielding a super-channel that allows more than 2.5 times increase in bandwidth in the same amount of spectral width as current DWDM technologies. Both the 400G and 800G transmission operated error-free.

“This field trial provided a significant opportunity for MAX and Fujitsu to collaborate on a leading technological advancement in the optical networking field,” said Tripti Sinha, Executive Director of MAX. “The achievement of such a fast networking speed will not only benefit MAX participants, but it will also set the standard for the future of advanced networking, helping to unlock previously unavailable resources for researchers across the world.”

Fujitsu also noted that the trial also employed Nyquist filtering techniques that leverage spectral shaping, resulting in an increase in spectral density. With nonlinear fiber impairments being a major limiting factor of optical transmission, the field trial demonstrated nonlinear compensation (NLC) techniques to reduce the resulting optical penalties and extend the achievable transmission distance. All of these advancements enable a much higher utilization of costly fiber infrastructure and maximize the bandwidth available for demanding R&E applications.

ONS 2014 Google Keynote: Software Defined Network Virtualization at Scale

Google is a big believer in cloud networking because it promises an easier operational model and opens the doors to state-of-the-art infrastructure and services, said Amin Vahdat, Distinguished Engineer and Technical Lead for Networking at Google, in a keynote for Open Networking Summit 2014 in Santa Clara, California.

Google's Cloud Platform is enabled by its "Andromeda Network Virtualization" platform -- a software-defined networking (SDN) framework extending across the entire hardware/software stack.  Google takes a holistic approach to all layers in order to achieve QoS, latency parameters and fault tolerance.   Google is making huge investments in its cloud data centers -- at least $2.9 billion in additional planned data centers worldwide in support of cloud services. As reported in the press, managing the energy consumption of these huge facilities is as important as ongoing capital spending.  The company has an extensive CDN footprint to reduce delivery times to end users.

In talks at previous Open Networking Summits, Google first described its global Software-defined WAN, describing the massive backbone as a homegrown project that has enabled the company to treat WAN bandwidth as though it were LAN bandwidth.

Some notes from Amin Vahdat's presentation:

  • Google adopted a share infrastructure model pretty much since its inception.  Hundreds of application run across the same cloud platform.
  • Google is into cluster networking, where storage is disaggregated into pools for virtual machines
  • Google has found that a logically centralized/hierarchical control plane with a peer-to-peer data plane beats out decentralized models.
  • The Andromeda Network Virtualization stack runs on this centralized/hierachical control plane model.
  • Network virtualization bring challenges:  virtual networks must be isolated from each others, DDoS attacks are a threat, network functions virtualization is key to the operation of these networks.
  • Looking ahead a few years, based on Amdahl's Law, Google calculates that future clouds will require extremely high bandwidth and low latencies to interconnect compute resources and shared pools of Flash storage.
  • Virtual machine migration capabilities will be key to support high-availability infrastructure.
  • Vahdat believes that commodity servers running control protocols will be widely used for SDN.
  • Google wishes to eliminate 'one-off' protocols and siloed middle boxes in its network.
  • Google is looking at programmable packet processors to extend network functionality
  • NFV is really about virtualized SDN
  • Andromeda is capable of splitting NFV between soft switches and commodity packet processors.
  • Andromeda capabilities also include cloud load balancing, virtual machine migration, storage services, bandwidth provisioning, and network configuration tools (ACLs, firewall and isolation)
The full keynote has now been posted online by @OpenNetworking Summit.

ONS 2014 AT&T Keynote: SDN Innovations Drive Transformation

AT&T is on a mission to transform its networks, operations, business models and even culture by leveraging a new spirit of innovation, said John Donovan, Senior Executive Vice President for AT&T Technology and Network Operations, in a key note address at Open Networking Summit in Santa Clara, California.

A key theme driving this transformation is openness, said Donovan, and AT&T is moving aggressively to implement "the network of the future" - what it calls the User-Defined Network Cloud, a multi-service, multi-tenant platform where equipment is flexible.

AT&T's User-Defined Network Cloud is all about becoming fast, nimble and more customer-focused, said Donovan.  AT&T will take an evergreen approach, preferring to build a new network rather than overlays on the legacy infrastructure.  AT&T will look at new, non-traditional networking vendors, the academic community and the open source movement.

Some notes on Donovan's presentation:

  • AT&T has led the way through several technology transformation inflection points over the course of its long history.  This will be one of them.
  • Over time, all of AT&T's network capabilities will become cloud-centric workloads
  • Customers will have more control to adapt their applications in real time.
  • Applications will pivot from traditional networking to cloud models.
  • AT&T will pursue openness everywhere, including with its Domain 2.0 program, to encourage opinions and innovations.
  • AT&T has half a dozen "beach-head" projects underway in NFV.
  • At times, AT&T will develop its own solutions.  For instance, the control plane of the AT&T backbone is already a software-defined network that manages the 4 million routes of the footprint.
  • AT&T is actively recruiting people with skills in these areas.

One question after the keynote was "why are you really moving to SDN?"  Donovan's answer:  "Because no army can hold back an economic principle whose time has come"

The entire keynote has now been posted on YouTube.
