Video interview with Cisco: What is OpFlex?

In this video, Tom Edsall, CTO of the Insieme business unit at Cisco, introduces OpFlex, a new policy protocol designed to support physical and virtual switching infrastructure.  OpFlex
provides an abstraction that Cisco believes is better suited than OpenFlow is scaling out policy.

Cisco has published an OpFlex draft in the IETF and will be releasing an OVS implementation in the public domain as well as a controller in the Open Daylight consortium.  The company hopes that open APIs will enable more equipment to be brought in under the OpFlex policy umbrella.  OpFlex fits in with Cisco's Application Centric Infrastructure vision.  Edsall describes differences between the imperative control plane model of "traditional SDN" and the declarative control plane of its ACI model, saying that some things should be centralized while others are best to be distributed.

In April, Cisco introduced OpFlex - a new networking protocol designed to open up its vision of Application Centric Infrastructure (ACI) in the data center for automated applications and interoperability with other software-defined networking (SDN) elements.


OpFlex is a southbound protocol that is co-authored by Citrix, IBM, Microsoft, and Sungard Availability Services. It provides a mechanism that enables a network controller to transfer abstract policy to a set of “smart” devices capable of directly rendering rich network policy on the device.  OpFlex will enable leading hypervisors, switches and network services (layer 4-layer 7) to self-configure driven by application policy.

Cisco is submitting to the IETF for standardization. It is also an open source Contribution that Cisco is making to OpenDaylight in partnership with IBM, Plexxi and Midokura.  Other companies that are supporting OpFlex include Microsoft, RedHat, F5, Citrix, Canonical, and Embrane.  Hypervisor and software vendors will support OpFlex-enabled virtual switches and extend the Cisco ACI policy framework in their virtual environments. Network services vendors like Avi Networks, Citrix, Embrane, and F5 Networks will be shipping an OpFlex agent with their appliances.

In addition, Cisco is working with OpenDaylight to create a 100 percent open source, ACI-compatible policy model and OpFlex reference architecture.

Compared to the current SDN model, Cisco said its Application Centric Infrastructure avoids the scalability/resiliency challenge of having a single SDN controller managing the state of the network. Its ACI approach is to distribute complexity to the edges and operate disconnected from a central policy manager.  It also would not require application developers to describe their requirements with low level constructs.

Cisco is planning to support the OpFlex Protocol on the following Cisco products:
  • Cisco Application Centric Infrastructure, Nexus 9000 Series
  • Cisco Nexus 1000V
  • Cisco ASR 9000 Series
  • Cisco Nexus 7000 Series
  • Cisco ASA
  • Cisco SourceFire

Cisco Expands its Service Provider Virtualization Platform

Cisco introduced an Evolved Services Platform (ESP) for Service Providers that leverages its software-defined networking (SDN) and network function virtualization (NFV) offerings.

The Cisco ESP is a unified virtualization and orchestration software platform that creates, automates and provisions services in real time, across compute, storage and network functions, to deliver desired business outcomes for applications running across multiple domains.

Cisco said the primary characteristics of this virtualization and orchestration software platform are:

  • Open: Cisco ESP is multi-vendor and based on open standards and incorporating Openstack and Open Daylight (SDN) protocol suite, it is fully compliant with ETSI NFV MANO, 3GPP and more. With interoperation of third-party software, Cisco ESP works with Cisco’s virtual functions and with other vendors’ functions and applications such as Metaswitch Networks and Openwave Mobility.
  • Extensible: Cisco ESP offers the most comprehensive broad set of capabilities with more on the way and spanning across the entire service provider architecture – cloud, video, mobile and fixed – to provide service providers greater means to optimize their networks or create, automate the creation of new services as the business needs dictate.
  • Elastic: Cisco ESP allows service providers to seamlessly and dynamically scale their existing services while also dramatically accelerating deployment of new services and network functions. Resources are harnessed in an automated way when and where they are needed to enable providers deliver “On Demand” offerings at web speed.

As part of this ESP framework, Cisco is announcing the the first two modules:

  • Video: Cisco Videoscape Cloud DVR Solution – cloud-driven video recording with capture and storage in the cloud instead of the end device. Consumers can restart shows, catch up on past programs, and play back digital video recorder-captured content from anywhere, on any screen. For the service provider, it enables new multi-screen offers. It is currently deployed in a major North American video operator.
  • Mobility: Cisco Virtualized Mobile Internet – New virtualized mobile services, such as sponsored data, where the content provider pays to deliver data to the user, provide new revenue opportunities for service providers. Such capabilities are now possible in an even broader use case with the introduction of the Cisco Quantum Virtualized Packet Core (vPC), the Cisco Virtual Gi-LAN capabilities and the Cisco Quantum Services Bus. It is currently in trials at China Mobile as well as other service providers.


Significantly, Cisco will sell these SDN + NFV solutions in four ways:

Virtual Functions: Individual virtual functions may be purchased independently as a separate module and run in a network over general computing (e.g., hardware independent and hypervisor independent).

Orchestrated: Virtualized functions and orchestration, which enables the benefits of the all the different capabilities to work in a “networked” or “service chaining” approach  to deliver expanded functionality and address even wider market opportunities.

Pod: Virtualized service functions combined with orchestration and a hardware package -- implementation in a Pod approach -- Cisco leads the deployment of the Cisco ESP and offers service level agreements and guaranteed performance, working atop of Cisco infrastructure and including Cisco integration consulting services.

“As a Service”: A model where complete service offers that include virtualized service functions combined with orchestration and delivered through a hosted or third-party cloud for faster time-to-market, using a pay-as-you-go model.

“Service providers success is dependent on providing a consistent experience, agility to roll out new services and the ease at which these services can be ordered, automated, managed and delivered,” said Pankaj Patel, executive vice president and chief development officer, Cisco. “Service providers globally view virtualization not just to reduce costs but to have it work with their infrastructure to provide even greater value by means of increased agility and elasticity. As the industry leader in networking, we are not only committed to but executing on our strategy to enable our customers through this transition.”

In January, as part of its recently launched Application Centric Infrastructure (ACI) initiative, Cisco introduced an Application Policy Infrastructure Controller (APIC) Enterprise Module for extending high-performing applications from the data center to wide-area networks (WAN) and local access networks (LAN). The goal is to provide enterprises with complete visibility into their networks, automating network and policy configuration while managing applications across the WAN and access networks.

The Cisco APIC serves as the single point of automation and fabric element management in
both physical and virtual environments.

The Cisco APIC Enterprise Module is constructed of three elements: a consolidated network information database, policy infrastructure and automation.

To address security concerns, Cisco APIC automates network-wide rapid threat detection and mitigation by integrating and automating Cisco Sourcefire  security solutions.  For compliance management across branches and headquarters, Cisco APIC also provides network-wide Quality of Service (QoS), and accelerates Intelligent WAN (IWAN) deployments. It can also be used with third-party solutions to provide an end-to-end WAN orchestration and management.
