Video: White box Adoption Moves to the Edge

White boxes are not just a data center story anymore, says Pica8's Calvin Chai.

New use cases are emerging for delivering network services at the customer prem. This will be a key opportunity for white boxes. Another consideration, the risk profile for using white boxes at the customer edge is lower than for whiteboxes in a data center.

Azure Service Fabric Powers Microsoft's Cloud

Microsoft's Azure Service Fabric is a microservice application platform that allows developers to decompose their work into logical subsystems that are loosely coupled and can be updated independently.

In this video, Mark Russinovich, Chief Technology Office for Microsoft Azure,  talks about how Azure Service Fabric is becoming a key differentiator for the company's cloud initiatives.

Recorded at Open Networking Summit 2015 in Santa Clara, California.

#ONS2015 - Microsoft Azure Puts SDN at Center of its Hyperscale Cloud

To handle its hyperscale growth, Microsoft Azure must integrate the latest compute and storage technologies into a truly software-defined infrastructure, said Mark Russinovich, Chief Technology Officer of Microsoft Azure in a keynote presentation at the Open Networking Summit in Santa Clara, California. The talk covered how Microsoft is building its hyperscale SDN, including its own scalable controllers and hardware-accelerated hosts.  Microsoft...

Open networking shifts the dynamics to SDN apps

The whole Open Networking revolution is really about transforming how infrastructure is built, and changing the dynamics from switches and protocols to the business applications, says Kumar Srikantan, President and CEO of Pluribus Networks.

If you think about this, it's no different that what has happened in the world of mobile devices.  Android and iOS are not really about mobile telephony but rather a platform for other applications.

Open networking is all about enabling the next generation of applications.

Open is the way to innovate in your network, says Guido Appenzeller

Open is the way to innovate in your network, says Guido Appenzeller, Chief Technology Strategy Officer for VMware's Network & Security business unit.

If you go back 15 years, servers were closed too. Today, there are many choices for servers and it only takes a few clicks to spin-up a new VMs.  Networks need this same DevOps mindset.  The ability to pick the software that runs your network independently of the hardware is a huge step forward and will usher in the 'golden age of networking.'

Open networking is driven by sound economics says Cliff Young

Open networking is driven by sound economics, says ClearPath Networks' Cliff Young.

To head off the over-the-top challenge, network operators need solutions that are much more interoperable, much more flexible and much more software-defined.

Clearpath is excited about OPNFV as the common platform for service providers. Virtual CPE offers the potential to extend network functions directly to the customer.

By open, we mean not controlled by a single party, says Dan Pitt

Customers love open... but "open" has many different flavors and varieties, says Dan Pitt, Executive Director of the Open Networking Foundation.

"We've been strong advocates of open SDN for a long time. "

"By open, we mean not just published, but not controlled by a single party. It is good that people are opening up and publishing. There are open standards, open specifications, and open interfaces.  It is important that they be community-defined."

Everything that can be virtualized will be virtualized, says @Infinera's Stuart Elby

Open networking brings experts from across the industry together to focus on common problems, says Stuart Elby, SVP, Data Center  Business Group at Infinera.  This leads to faster time-to-market, more use cases, and more security, as more eyes can look out for vulnerabilities.

Disruptive innovations first occur through proprietary solutions but are later subsumed by the open source community.  We are on the verge of seeing that for SDN and NFV.

Everything that can be virtualized will be virtualized. However, no one has figured out how to virtualize photons. This means there are still real optical layer with photons moving through ROADMs, transponders and amplifiers.

#ONS2015 - A Look Inside Google's Data Center Network

Networking is at an inflection point in driving next-gen computing architecture, said Amin Vahdat, Senior Fellow and Technical Lead for Networking at Google, in a keynote address at the Open Networking Summit in Santa Clara, California. Creating great computers will largely be determined by the network.

In constructing its "Jupiter" fifth-generation data centers, Google is essentially the bandwidth equivalent of the Internet under one roof.

Some key takeaways from the presentation:
  • Google will open source its gRPC load-balance and app flow-control code 
  • Google's B4 software-defined WAN links its global data centers and is bigger than its public-facing network
  • Andromeda Network Virtualization continues to advance as a means to slice the physical network into isolated, high-performance components
  • Google is deploying its "Jupiter" fifth-generation data center architecture.  Traditional designs and data center switches simply cannot keep up and require individual management, so Google decided to build its own gear.
  • Three principles in Google's data center network are: Clos Topologies, Merchant Silicon, and Centralized Control. Everything is designed for scale-out.
  • Load balancing is essential to ensure that resources are available and to manage cost.
  • Looking forward, a data center network may have 50,000 servers, each with 64 CPU cores, access to PBs of fast Flash storage, and equipped with 100G NICs.  This implies the need for a 5 Pb/s network core switch -- more than the Internet today!

#ONS2015 - Microsoft Azure Puts SDN at Center of its Hyperscale Cloud

To handle its hyperscale growth, Microsoft Azure must integrate the latest compute and storage technologies into a truly software-defined infrastructure, said Mark Russinovich, Chief Technology Officer of Microsoft Azure in a keynote presentation at the Open Networking Summit in Santa Clara, California.

The talk covered how Microsoft is building its hyperscale SDN, including its own scalable controllers and hardware-accelerated hosts.

 Microsoft is making a massive bet on Azure.  It is the company's own infrastructure as well the basis for many of its products going forward, including Office 365, Xbox and Skype.

Some highlights:
  • Microsoft Azure's customer facing offering include App Services, Data Services and Infrastructure Services
  • Over 500 new features were added to Azure in the past year, including better VMs, virtual networks and storage.
  • Microsoft is opening new data centers all over the world
  • Azure is running millions of compute instances
  • There are now more than 20 ExpressRoute locations for direct connect to Azure.  
  • Azure connects with 1,600 peered networks through 85 IXPs
  • One out of 5 VMs running on Azure is a Linux VM
  • A key principle for Microsoft's Hyperscale SDN is to push as much of the logic processing down to the servers (hosts)
  • Hyperscale controllers must be able to handle 500K+ server (hosts) in a region
  • The controller must be able to scale down to smaller data centers as well
  • Microsoft Azure Service Fabric is a platform for micro-service-based applications
  • Microsoft has released a developer SDK for its Service Fabric
  • Azure is using a Virtual Filtering Platform (VFP) to act as a virtual switch inside Hyper-V VMSwitch.  This provides core SDN functionality for Azure networking services. It uses programmable rule/flow tables to perform per-packet actions. This will also be extended to Windows Server 2016 for private clouds.
  • Azure will implement RDMA for very high performance memory transport between servers. It will be enabled at 40GbE for Azure Storage.  All the logic is in the server.
  • Server interface speeds are increasing: 10G to 40G to 50G and eventually to 100G
  • Microsoft is deploying FPGA-based Azure SmartNICs in its servers to offload SDN functions from the CPU. The SmartNICs can also perform crypto, QoS and storage acceleration.

#ONS2015: AT&T Envisions its Future as a Software Company

Over the new few years, AT&T plans to virtualize and control more than 75% of its network functions via its new Domain 2.0 infrastructure.  The first 5% will be complete by the end of this year, laying the foundation for an accelerated rollout in 2016.

In a keynote at the Open Networking Summit 2015 in Santa Clara entitled "AT&T's Case for a Software-Centric Network", John Donovan provided an update on the company's Domain 2.0 campaign, saying this strategic undertaking is really about changing all aspects of how AT&T does business.

Donovan, who is responsible for almost all aspects of AT&T's IT and network infrastructure, said AT&T is deeply committed to open source software, including contributing back to open source communities. The goal is to "software-accelerate" AT&T's network.  In the process, AT&T itself becomes a software company.

Here are some key takeaways from the presentation:

  • Since 2007, AT&T has seen a 100,000% increase in mobile data traffic
  • Video represents the majority of traffic on the mobile network
  • Ethernet ports have grown 1,300% since 2010
  • AT&T's network vision is rooted in SDN and NFV
  • The first phase is about Virtualizing Functions.
  • AT&T's Network On-Demand service is its first SDN application to reach customers. It went from concept to trials in six months.
  • The second phase is about Disaggregation.
  • The initial target of disaggregation is the GPON Optical Line Terminals (OLTs), which are deployed in central offices for supporting its GigaPower residential broadband service.  AT&T will virtualize the physical equipment using less expensive hardware.  The company will release an open specification for these boxes.
  • AT&T will contribute its YANG custom design tool to the open source community.
  • AT&T is leading a Central Office Re-architected as Data Center (CORD) project.

Internet2 Deploys ONOS to Provision Virtual Nets

Internet2 has deployed the Open source SDN Network Operating System (ONOS) on its nationwide research and education (R&E) network.

Five higher education institutions — Duke University, Florida International University, the Indiana GigaPoP, MAX and the University of Maryland – College Park, and the University of Utah — are connected to a virtual slice of the Internet2 nation-wide network that is piloting this next-generation advanced network technology.

Internet2 said it is using the capabilities of its SDN substrate to provision virtual networks based on FlowSpace Firewall. An ONOS cluster is deployed in a virtual network slice on the Internet2 network, controlling 38 OpenFlow-enabled Brocade and Juniper switches. The SDN-IP Peering application deployed atop ONOS peers with other, traditional networks. An SDN-based network like Internet2 provides benefits such as network programmability, lower TCO and removal of vendor lock-in. In this particular case, the centralized control plane leads to significant improvements in network operation efficiency for the Internet2 network.

“We worked closely together in a lab environment to prepare ONOS for production deployment on the Internet2 Network, providing many valuable insights on production deployment of SDN-controlled virtual networks in a multi-tenant environment,” said Luke Fowler, director of software and systems for the GlobalNOC.

“A primary feature of the Internet2 Network is its ability to serve as a ‘playground’ for piloting new advanced networking capabilities in a real-world environment with demanding users and advanced applications capabilities,” said Vietzke. “The ONOS and SDN-IP peering deployment is another demonstration of how Internet2 and the academic community continue to be a large scale platform in which pre-market innovations can be prototyped at scale.”

"ON.Lab, the ONOS Project and Internet2 have a very synergistic collaboration. At ON.Lab we develop interesting open source SDN platforms and Internet2 is a keen early adopter bringing new capabilities to its customers,” said Bill Snow, vice president of Engineering for ON.Lab. “With the deployment of ONOS on Internet2’s nationwide network, we get to validate and demonstrate ONOS’s scalability, performance and high availability in a production setting and learn from this experience to make ONOS better.”

AT&T and ONOS to Show Central Office Re-architected as Data Center (CORD)

At next week's Open Networking Summit (ONS2015) in Santa Clara, California, AT&T, ONOS project, PMC-Sierra and Sckipio will showcase the first public demonstration of the Central Office Re-architected as Data Center (CORD) proof-of-concept (POC).

The idea behind CORD is to use SDN and NFV to transform carrier functions into workloads that are hosted on common, commodity infrastructure. The CORD solution POC spans the Telco Central Office, access including Gigabit-capable Passive Optical Networks (GPON) and as well as home/enterprise customer premises equipment (CPE). CORD enables service providers to build an underlying common infrastructure with white boxes using ONOS (carrier-grade open source SDN Control Plane), OpenStack (virtual infrastructure management), and XOS (an open source service orchestration/management platform built on OpenStack) with a diversity of organizations building the services and solutions that ride above.

Key capabilities demonstrated at ONS will include:
  • Proof-of-concept Central Office: Highlights the open software and hardware building blocks for CORD - ONOS, XOS, OpenStack, white box switches, commodity servers, OpenFlow-enabled GPON OLT MAC from PMC, and OpenFlow-enabled distribution point unit (DPU) connected to a CPE bridge from Sckipio.
  • Service Provider-focused capabilities
  • SDN Control, orchestration and management with ONOS, OpenStack and XOS on commodity infrastructure
  • An open high-performance leaf-spine fabric
  • OpenFlow-enabled PON OLT MAC hardware enabling virtualization of the traditional OLT
  • OpenFlow-enabled DPU
  • Access-as-service, Subscriber-as-a-service, Internet-as-a-service Caching/Content delivery-as-a-service, Virtualized functions including Firewall, URL Filtering, Parental Control, BNG
  • Service Provider portal for intuitive provisioning, management, monitoring of infrastructure and services
  • Subscriber-focused capabilities
  • A simple CPE that replaces existing complex CPEs and can be managed by ONOS
  • Subscriber Services: Internet, Firewall, Parental Control
  • Subscriber portal for signing up for and managing services
  • Third-Party Provider-focused capabilities
  • Third-party provider services: Content delivery (Caching) for its own content in the Service Provider network
  • Third-party provider portal for signing up for and managing services
  • CORD POC software used for the demo at ONS 2015 will be available publicly in the ONOS "Drake" release that is slated for the end of August, 2015. Beyond the ONS demo, the CORD solution will undergo the next phase of development and advance to lab trials. A CORD "Pod" bundling together the software and hardware building blocks into a ready-to-use system, will be made available for service provider lab trials by the end of 2015.

"SDN and NFV are speeding up innovation, as seen in projects like CORD," said Tom Anschutz, Distinguished Member of Technical Staff at AT&T. "These technologies create systems that do not need new standards to function and enable new behaviors in software, which decreases development time. Faster development time leads to rapid innovation, something the industry needs to continue satisfying data-hungry customers."

"The first CORD proof-of-concept is a big step towards demonstrating AT&T and other providers' vision of reinventing the central office to bring data center economies of scale and cloud-style agility to their networks," said Guru Parulkar, Executive Director, ON.Lab and ONRC. "With CORD, service providers can architect their central offices using common, commodity infrastructure such as ONOS, OpenStack, XOS, white box switches and servers. CORD also represents an open and unique opportunity with AT&T as the leading service provider, ON.Lab and ONOS project as providers of open source software platforms, and merchant silicon vendors PMC-Sierra and Sckipio. This team plans to enhance the solution with new features and harden it, bring in new players and advance CORD from lab trials all the way to deployment."
