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)

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.

Open Networking Summit 2014 Gets Underway in Silicon Valley

Open Networking Summit 2014 got underway in Santa Clara, California.  This year's ONS features high-profile keynotes from AT&T, Google, Microsoft and Khosla Ventures.

The conference offers sessions on topics such as "Bare Metal Switching & Programming", "SDN for Cellular Networks" and "SDN Deployment Experiences."  It also features over 60 SDN exhibits; a Demo Track with SDN Idol Finalists, and an SDN Solutions Showcase.

Two keynotes are scheduled for Tuesday:

08:30A - 09:30A: "SDN AS A DISRUPTIVE INNOVATION," Vinod Khosla, Khosla Ventures

11:45A - 12:30P: "HOW AT&T PLANS TO TRANSFORM ITS INFRASTRUCTURE WITH SDN", John Donovan, Senior Executive Vice President—AT&T Technology and Network Operations, AT&T Inc.

NEC Debuts OpenFlow-based Data center Interconnect Solution

NEC announced the commercial release of Version 5.1 of its ProgrammableFlow Networking Suite, which introduces a new OpenFlow-based, software-defined data center interconnect solution – the Unified Network Coordinator (UNC).

NEC says its new UNC significantly improves the scalability of the network controller by 10 times over previous ProgrammableFlow controllers. This enables construction and orchestration of virtual networks across multiple controllers within a data center as well as across interconnects between data centers. The UNC's capability of linking virtual networks across and between data centers gives customers the ability to link to specific policies within the UNC. In turn, users gain the ability to have an end-to-end policy across multiple controllers and multiple domains.

"We've found that our customers are looking for a policy-based approach to managing their data centers, which is now possible with NEC's UNC," said Don Clark, director of business development, NEC Corporation of America. "The ProgrammableFlow version 5.1 controller allows for better resource utilization and it simplifies data center management, both of which can increase service agility and reduce operating costs. Customers can deploy the UNC to move workloads across multiple data centers and control how traffic flows across WAN links. This allows the pooling of resources, which equates to better utilization of not only networks, but also storage and servers."

As an illustration of its 10x* scalability, each ProgrammableFlow UNC controls up to:

  • 10 controllers or 10 sites or 10 zones in a large data center
  • 2,000 switches (compared to 200 switches per controller in previous version)
  • 30,000 Virtual Tenant Networks (VTN)
  • 100,000 VLANs
  • 10 million flows

ONF Releases Educational Network Tapping Application

The Open Networking Foundation (ONF) released an open-source network tapping application built on OpenFlow and designed to serve as an educational resource for programmers.

The application was developed with Wiretap Labs, a Silicon Valley-based consultancy specializing in custom development for cloud, security and SDN solutions. of March 2014. It is based on OpenFlow 1.0 and was written to run on an OpenDaylight controller. SampleTap has been tested and will be demonstrated with OpenFlow Conformance-Certified NEC switches. It was based on OpenFlow 1.0 because the recently announced OpenDaylight Hydrogen release, which supports OpenFlow 1.3, was not available at the time of the app’s writing. It was also designed for easy portability to other network operating systems and support later versions of OpenFlow. The ONF noted that a number of its member companies, including Big Switch Networks, Cisco, Gigamon, HP, IBM, Ixia (Net Optics), NEC, and NetScout, offer or plan to offer commercial-grade network tapping products.

“In evaluating potential educational applications, we selected network tapping as it is broadly understood and easily deployable by network operators,” said Dan Pitt, executive director of the Open Networking Foundation. “We see our app as an OpenFlow teaching tool that allows network operators to get experience with OpenFlow without changing how they actually do the switching and routing, since tapping doesn’t use OpenFlow for forwarding.”

"We hear tremendous interest from users who want to test OpenFlow in their networks and this app is the perfect way for them to get started," said Neela Jacques, executive director, OpenDaylight. "We are excited that ONF used OpenDaylight's controller for this and look forward to hearing how these open source technologies are being implemented in software-defined networks."

ONF will be demonstrating the SampleTap application at this week's Open Networking Summit in Santa Clara.
