After living and breathing open source since experimenting in high school, there is nothing as sweet as sharing your latest project with the world! Today, CableLabs is thrilled to announce the extension of our SNAPS-OO initiative with two new projects: SNAPS-Boot and SNAPS-OpenStack installers. SNAPS-Boot and SNAPS-OpenStack are based on requirements generated by CableLabs to meet our member needs and drive interoperability. The software was developed by CableLabs and Aricent.

SNAPS-Boot

SNAPS-Boot will prepare your servers for OpenStack. With a single command, you can install Linux on your servers and prepare them for your OpenStack installation using IPMI, PXE and other standard technologies to automate the installation.

SNAPS-OpenStack

The SNAPS-OpenStack installer will bring up OpenStack on your running servers. We are using a containerized version of the OpenStack software. SNAPS-OpenStack is based on the OpenStack Pike release, as this is the most recent stable release of OpenStack. You can find an updated version of the platform that we used for the virtual CCAP core and mobile convergence demo here.

We encourage you to go to GitHub and try for yourself: 

Why SNAPS?

SNAPS (SDN & NFV Application Platform and Stack) is the overarching program to provide the foundation for virtualization projects and deployment leveraging SDN and NFV. CableLabs spearheaded the SNAPS project to fill in gaps in the open source community to ease the adoption of SDN/NFV with our cable members by:

Encouraging interoperability for both traditional and prevailing software-based network services: As cable networks evolve and add more capabilities, SNAPS seeks to organize and unify the industry around distributed architectures and virtualization on a stable open source platform to develop baseline OpenStack and NFV installations and configurations.

Network virtualization requires an open platform. Rather than basing our platform on a vendor-specific version, or being over 6 months behind the latest OpenStack release, we added a lightweight wrapper on top of upstream OpenStack to instantiate virtual network functions (VNFs) in a real-time dynamic way.

Seeding a group of knowledgeable developers that will help build a rich and strong open source community, driving developers to cable: SNAPS is aimed at developers who want to experiment with building apps that require low latency (gaming, virtual reality and augmented reality) at the edge. Developers are able to share information in the open source community on how they optimize their application. This not only helps other app developers, but helps the cable industry understand how to implement SDN/NFV in their networks and gain easy access to these new apps.

At CableLabs, we pursue a “release early” principle to enable contributions to improve and guide the development of new features and encourage others to participate in our projects. This enables us to continuously optimize the software, extend features and improve the ease of use. Our subsidiary, Kyrio, is also handling the integration and testing on the platform at their NFV Interoperability lab.

You can find more information about SNAPS in my previous blog posts “SNAPS-OO is an Open Sourced Collaborative Development” and “NFV for Cable Matures with SNAPS

Who benefits from SNAPS?

  • App Developers will have access to a virtual sandbox that allows them to test how their app will run in a cable scenario, saving them time and money.
  • Service providers, vendors and enterprises will be able to build more exciting applications, on a pure open source NFV platform focused on stability and performance, on top of the cable architecture.

How we developed SNAPS:

We leverage containers which have been built and tested by the OpenStack Kolla project. If you are not familiar with Kolla, it is an OpenStack project that maintains a set of Docker containers for many of the OpenStack components. We use these scripts to deploy the containers because the Kolla-Ansible scripts are the most mature and include a broad set of features which can be used in a low latency edge data center. By using containers, we are improving the installation process and updating.

To maximize the usefulness of the SNAPS platform, we included many of the most popular OpenStack projects:

Additional services we included:

Where the future of SNAPS is headed:

  • We plan to continue to make the platform more robust and stable. 
  • Because of the capabilities we have developed in SNAPS, we have started discussions with the OPNFV Cross Community Continuous Integration (XCI) project to use SNAPS OpenStack as a stable platform for testing test tools and VNFs with a goal to pilot the project in early 2018.
  • Aricent is a strong participant in the open source community and has co-created the SNAPS-Boot and SNAPS-OpenStack installer project. Aricent will be one of the first companies to join our open source community contributing code and thought leadership, as well as helping others to create powerful applications that will be valuable to cable.
  • As an open source project, we encourage other cable vendors and our members to join the project, contribute code and utilize the open source work products.

There are three general areas where we want to enhance the SNAPS project:

  • Integration with NFV orchestrators: We are including the OpenStack NFV orchestrator (Tacker) with this release and we want to extend this to work with other orchestrators in the future.
  • Containers and Kubernetes support: We already have some support for Kubernetes running in VMs.  We would like to evaluate the benefit of running Kubernetes with or without the benefit/overhead of VMs.
  • Serverless computing: We believe that Serverless computing will be a powerful new paradigm that will be important to the cable industry and will be exploring how best to use SNAPS as a Serverless computing platform.

Virtualization

SNAPS-OO is an Open Sourced Collaborative Development Resource

Randy Levensalor
Principal Architect, Future Infrastructure Group, Office of the CTO

Mar 21, 2017

In a previous blog, I have provided an overview of the SNAPS platform which is CableLabs’ SDN/NFV Application development Platform and Stack project. The key objectives for SNAPS are to make it much easier for NFV vendors to onboard their applications, provide transparent APIs for various kinds of infrastructure and reduce the complexity of integration testing.

I am thrilled to share our latest SNAPS success.  We have written an OpenStack API abstraction library that also contains many automated tests and we have contributed it to the Open Platform for NFV (OPNFV) project at the Linux Foundation.  OPNFV is a project where service providers and network vendors collaborate to improve the capabilities and adoption of open source Network Functions Virtualization (NFV). Our results have also been shared at NFV World Congress, SDN World Congress, OPNFV Summit [video], Open Networking Summit (ONS) [video] [pdf] and the Big Communications Event (BCE).

The Rationale for our Approach

CableLabs has deep expertise developing specifications by following a collaborative, iterative approach.  In many ways, the open source software development process mirrors many of these specification development processes.  In the open source communities, CableLabs provides source code and feedback coming from our integration and debugging activity.  In fact, CableLabs contributions are included in key open source projects such as OpenStack and OpenDaylight.  In this way, we are making it easier for vendors to use open source projects to build solutions for the benefit of the entire ecosystem.

We have generated practical knowledge and insights through our hands-on experience of building and operating an active SDN/NFV application development lab.  And we took vendor neutrality to the next level by basing our software stack on purely open source solutions and based on the OPNFV reference configuration.  We did not use versions of OpenStack, OpenDaylight, etc. that have been tested and customized by a vendor.  This allowed us to interact with a much larger community for new features and fixes.

The CableLabs team supported by vendors and services providers has moved our project into OPNFV as “SNAPS-OO”, based on the idea that it is an Object Oriented way to work with our SDN/NFV Application development Platform and Stack.  The project was quickly accepted and is now being used by the release testing team to verify each OPNFV build.  With the integration of SNAPS-OO into the OPNFV FuncTest project, our contributions are now part of the release criteria and suite of tests that will be used at the upcoming OPNFV PlugFest next month.

Some of the benefits that SNAPS-OO delivers are:

  • Ease of use for new developers
  • A rich library of example applications and test suites
  • Support for accessing multiple secured clouds
  • Automated cleanup of the NFVI when updates are applied
  • Quick identification of component failure(s)

As a result of this open source approach, and in just a few weeks since SNAPS-OO was released, we have seen a significant increase in the level of contributions and adoption.

Next Steps

  • Continue to expand the capabilities supported by SNAPS-OO.
  • Encourage additional OPNFV projects to use SNAPS-OO.
  • Use SNAPS-OO and other tools to run much more sophisticated SDN/NFV workloads.
  • Share SNAPS-OO with more open source communities.

How SNAPS-OO Benefits Our Membership

SNAPS-OO is helping to improve the quality of the open source projects associated with the NFV infrastructure and Virtualization Infrastructure Managers that many members are using today and plan to use in the future.  SNAPS-OO can be used to validate that the infrastructure is installed properly and it will be playing a key role in the Kyrio NFV Interoperability lab.  Future NFV development provided by vendors will benefit from the use of SNAPS-OO.  With the variety of workloads that we will be running on our SNAPS platform, we will be able to specify a single configuration that can run future NFV workloads alongside other cloud hosted applications.
