FRINX UniConfig is now powered by PANTHEON.tech’s lighty.io

What is lighty.io?

lighty.io is an SDK that provides components for the development of SDN controllers and applications based on well-established standards in the networking industry. It takes advantage of PANTHEON.tech’s extensive experience from the involvement in the OpenDaylight platform and simplifies and speeds up the development, integration, and delivery of SDN solutions.

lighty.io also enables SDN programmers to use ODL services in a plain JavaSE environment. lighty.io enables a major OpenDaylight distribution vendor to build and deploy their applications faster.

FRINX UniConfig

FRINX UniConfig provides a common network API across physical and virtual devices from different vendors. It leverages an open source device library, which offers connectivity to a multitude of networking devices and VNFs.

The API provides the ability to store intent and operational data from services and devices, enables to commit intent to the network, syncs from the network so that the latest device state is reflected in the controller, compares intended state and operational state and provides device and network wide transactions. All changes are applied in a way that only those parts of the configuration that have changed are updated on the devices.

The UniConfig framework consists of distinct layers, where each layer provides a higher level of abstraction. APIs of the lowest layer provides the ability to send and receive unstructured data to and from devices. The unified layer provides translation capabilities to and from OpenConfig. The UniConfig layer provides access to the intent and the actual state of each device plus the capability to perform transactions and rollback of configurations.

NETCONF devices can be configured via their native YANG models or via OpenConfig. Finally, FRINX UniConfig also provides service modules based on IETF YANG models for the configuration of L2VPNs, L3VPNs and enables the collection of LLDP topology information in heterogeneous networks.

The UniConfig Framework is based on open source projects like OpenDaylight and Honeycomb. It publishes all translation units under the Apache v2 license. Customers and integration partners can freely contribute, modify and create additional device models, which work with the UniConfig Framework.

How did PANTHEON’s lighty.io help?

PANTHEON.tech’s lighty.io helped to make UniConfig run and build faster.

Porting UniConfig to lighty.io required no changes to the application code and has brought many measurable improvements. UniConfig now starts faster, has a smaller memory footprint, and most importantly – significantly reduces build time.

lighty.io packs many features, some of which are:

  • Client libraries for communication with ODL back end for Java, Python, and Golang
  • Enhanced NETCONF device simulator
  • Microservice friendly structure
  • Easy to use utilities for YANG model data serialization and deserialization

lighty.io core becomes Open-Source

PANTHEON.tech, the proven supporter of open-source software and its communities, and leader in Software Defined Networking (SDN) and the OpenDaylight (ODL) platform, decided to open-source the core components of the current go-to SDN controller development kit: lighty.io.

Last Open Networking Summit, USA witnessed the announcement of lighty.io. This ONS will be the place where all OpenDaylight users will remember.

Today, PANTHEON.tech continues to push forward the open-source community projects and its commercial applications developed on open-source software, especially the lighty.io core.

What is lighty.io?

lighty.io journey started when we realized the way to move the upstream project to the direction we envisioned was to provide a solution rather than talk about it. Therefore we’ve focused on a solution of the biggest pain point of current ODL, and turned it into the idea-bearer of the whole product. We’ve taken the biggest obstacle – Apache Karaf, out of the ODL developers lives, and hence improving their efficiency tremendously.

On the other hand the lighty.io commercial product is available for purchase is developed using the same lighty.io core which gets open-sourced today. We are tirelessly adding new features with the demand and cooperation with our customers. Such as the lighty.io Network Topology Visualisation Component, Go/Java/Python RESTCONF clients, improved RESTCONF notifications with HTTP 2.0 support, improved southbound NETCONF plugin with the implemented support of YANG actions, NETCONF simulator to name a few.

Our vision from the start was to enhance the commercial version of lighty.io with bleeding edge features and improvements that are not yet in open-source ODL. This will leverage lighty.io users capability to speed up their development and deployment. Today lighty.io users will get the chance to experience these changes, instead of waiting until such improvements appear in the upstream or developing themselves.

PANTHEON.tech released lighty.io core components under Eclipse Public License v1.0 as a continuous support to the community.

Future of SDN

We believe this generous act will result in spinning up new projects based on OpenDaylight components making them faster and cheaper to develop and will give you a competitive edge in today’s fast evolving world of micro service and cloud-oriented deployments.

We encourage all OpenDaylight users, Data Center managers, Telco and Service Provider DevOps to give lighty.io a try with their existing applications. It will be amaze you.

Today, PANTHEON.tech will officially release the lighty.io core as free and open-source software at the event. Please join us in the Open Networking Summit Europe/Amsterdam at booth #14.

There is more to come, as we will reveal how lighty.io cuts down the software development costs and time, helping our customers to consume complex data center management features with ease.

Stay tuned and watch this space for the other great announcements around lighy.io which will take space in the event. Be there to witness the amazing.

lighty.io powers datacenter management at kaloom.com


Complete automation and full forwarding plane programmability

Private data centers are the hot topic for companies and enterprises who are not willing to push all the data into public clouds. Kaloom Software Defined Fabric™ (Kaloom SDF) is the world’s first fully programmable, automated, software-based data center fabric capable of running VNFs efficiently at scale. This is the first data center networking fabric on the market that provides complete automation and full forwarding plane programmability.

 approached PANTHEON.tech last year, knowing Pantheon’s intensive and long involvement in SDN, particularly iOpenDaylight project. OpenDaylight (ODL) is a modular open platform for orchestrating and automating networks of any size and scale. The OpenDaylight platform arose out of the SDN movement, in which PANTHEON.tech has expertise and experience. Hence, it was a logical step to utilize this expertise in this project and leverage what has already been done.

Traditional ODL based controller design was not suitable for this job because of bulkiness of the Karaf based deployments. Kaloom requested a modern web UI which vanilla ODL platform does not provide. lighty.io as a component library provides an opportunity to run ODL services such as: MD-SAL, NETCONF and YANG Tools in any modern web server stack, and integration with other components like MongoDB

Architecture

The following architecture is starting to be like a blueprint for SDN applications today. We utilize the best of both worlds:

  1. MD-SAL, NETCONF and YANG Tools from ODL
  2. Updated modern web stack Jetty/Jersey and
  3. MongoDB as a persistent data store.

 

This is how Kaloom Fabric Manager (KFM) project has started. After several months of  customizing development, we have deployed a tailored web application which provides management UI for Kaloom SDF. We have changed and tailored our Visibility Package application to suit Kaloom’s requirements and specifics. This specialized version uses the name of KFM. The architecture diagram above shows details/internals of the KFM and how we interconnect with Kaloom’s proprietary Fabric Manager/Virtual Fabric Manager controller devices.

The solution for physical data centers

lighty.io based back-end of the KFM with NETCONF plugin provides REST services to the Angular UI, which is using our Network Topology Visualization Component for the better topology view visualization and user experience. Using these REST endpoints, it is easy to send specific NETCONF RPC to the Kaloom SDF controllers.

While working on this next-gen Data Center Infrastructure Management software, we have realized that integrating all moving parts of the system is a crucial step for final delivery. Since different teams were working on different parts, it was crucial we could isolate the lighty.io part of the system and adapt it to the Kaloom SDF as much as possible. We have used our field-tested NETCONF device simulator from our lighty.io package to deliver the software which was tested thoroughly to provide stability of the KFM UI.

Kaloom SDF provides a solution for physical data centers administrated by Data Center Infrastructure Provider (DCIP) users. A physical data center can be easily sliced to virtual data centers offered to customers, called virtual Data Center Operator (vDCO) users. The DCIP user can monitor and configure the physical fabrics – PODs of the data center. KFM WEB UI shows the fabrics in topology view and allows updating the attributes of fabric and fabric nodes.

Topology View of Fabric Manager

Advantages for DCIP

The main task of DCIP user is to slice the fabrics to virtual data centers and virtual fabrics. This process involves choosing servers through associated termination points and associating them with the newly created virtual fabric manager controller. Server resources are used through the virtual fabric manager by vDCO users.

vDCO users can use the server resources and connect them via network management of their virtual data center. vDCO can attach server ports to the switches with proper encapsulation settings. After the switch is ready, vDCO can create a router and attach switches to it. The router offers different configuration possibilities to follow vDCO user’s needs: L3 interface configuration, static routing, BGP routing, VXLANs and many more. KFM offers also topology view of virtual data center network, so you can check relations between servers, switches, and routers.

Topology View of Fabric Manager

For more details about the KFM UI in action, please see the demo video with NETCONF simulator of Kaloom SDF bellow, or visit kaloom or kaloom academy

lighty.io runs 5G on xRAN

In April 2018, the xRAN forum released the Open Fronthaul Interface Specification. The first specification made publicly available from xRAN since its launch in October 2016. The released specification has allowed a wide range of vendors to develop innovative, best-of-breed remote radio unit/head (RRU/RRH) for a wide range of deployment scenarios, which can be easily integrated with virtualized infrastructure & management systems using standardized data models.

This is where PANTHEON.tech came to the scene. We became one of the first companies to introduce full stack 5G compliant solution with this specification.

Just a few days spent coding and utilizing the readily available lighty.io components, we created a Radio Unit (RU) simulator and an SDN controller to manage a group of Radio Units.

Now, let us inspect the architecture and elaborate on some important details.

We have used lighty.io, specifically the generic NETCONF simulator, to set up an xRAN Radio Unit (RU) simulator. xRAN specifies YANG models for 5G Radio Units. lighty.io NETCONF device library is used as a base which made it easy to add custom behavior and 5G RU is ready to stream data to a 5G controller.

The code in the controller pushes the data collected from RUs into Elasticsearch for further analysis. RU device emits the notifications of simulated Antenna Line Devices connected to RU containing:

  • Measured Rx and Tx input power in mW
  • Tx Bias Current in mA (Internally measured)
  • Transceiver supply voltage in mV (Internally measured)
  • Optional laser temperature in degrees Celsius. (Internally measured)

*We used device xRAN-performance-management model for this purpose.

lighty.io as a 5G controller

With lighty.io we created an OpenDaylight based SDN controller that can connect to RU simulators using NETCONF. Once RU device is connected, telemetry data is pushed via NETCONF notifications to the controller, and then directly into Elasticsearch.
Usually, log stash is required to upload data into Elasticsearch. In this case, it is the 5G controller that is pushing device data directly to Elasticsearch using time series indexing.
On Radio Unit device connect event, monitoring process automatically starts. RPC-ald-communication is called on RU device collecting statistics for:

  • The Number of frames with incorrect CRC (FCS) received from ALD – running counter
  • The Number of frames without stop flag received from ALD – running counter
  • The number of octets received from HDLC bus – running counter

*We used xran-ald.yang model for this purpose.
The lighty.io 5G controller is also listening to notifications from the RU device mentioned above.

Elasticsearch and Kibana

Data collected by the lighty.io 5G controller via RPC calls and notifications are pushed directly into Elasticsearch indices. Once indexed, Elasticsearch provides a wide variety of queries upon stored data.
Typically, we can display several faulty frames received from “Antenna Line Devices” over time, or analyze operational parameters of Radio Unit devices like receiving and transmitting input power.
Such data are precious for Radio Unit setup, so the control plane feedback loop is possible.

By adding Elasticsearch into the loop, data analytics or the feedback loop became ready to perform complex tasks. Such as: Faulty frame statistics from the “Antenna Line Devices” or the  Radio Unit operational setup

How do we see the future of xRAN with lighty.io?

The benefit of this solution is a full stack xRAN test. YANG models and its specifications are obviously not enough considering the size of the project. With lighty.io 5G xRAN, we invite the Radio Unit device vendors and 5G network providers to cooperate and build upon this solution. Having the Radio Unit simulators available and ready allows for quick development cycle without being blocked by the RU vendor’s bugs.

lighty.io has been used as a 5G rapid application development platform which enables quick xRAN Radio Unit monitoring system setup.
We can easily obtain xRAN Radio Unit certification against ‘lighty.io 5G controller’ and provide RU simulations for the management plane.

lighty.io in Data Center Management

The advantages of deploying lighty.io in Data Center Infrastructure Management (DCIM)

The DCIM market is continuing to evolve and large enterprises continue to be the primary adopters of new DCIM software solutions. The goal of a DCIM software initiative is to provide administrators the ability to identify, locate, visualize, and manage all physical data center assets with a holistic view.

PANTHEON.tech has developed lighty.io based on OpenDaylight in Java SE. It is a great software for implementation of customized DCIM solutions such as SDN controller, NFV orchestrator or VNF management etc.

Some of the great features, you will benefit from while managing your data center are listed below.

lighty.io scheme and use-case description

Model-driven approach

lighty.io implements a model-driven approach to data center infrastructure management. Because of the common models being used, intercommunication of configurational, operational, monitoring and telemetry data in all the parts of the systems becomes possible which are based on lighty.io.

These models define structure, syntax, and semantics of the data processed by each part of the system. Usage of standardized models by vendors (e.g., models from OpenConfig or IETF) leads to seamless migration from one vendor to another.

Scalability and controller hierarchy

  • Horizontal scalability – lighty.io supports clustering. A feature, which allows horizontal scaling of the system by adding more instances (nodes) of the controller into a cluster
  • Controller hierarchy – NB plugins of lighty.io allow the implementation of upper layer applications running as micro services and performing operations using the controller’s NB plugin API. It is also possible to design a hierarchy of controllers where the upper layer controller(s) performs operations using the lower layer controller’s NB plugins. One of the implemented NB plugins is a plugin that implements the NETCONF protocol. Using this NB plugin in the hierarchy of controllers makes possible to manage the lower layer controllers as NETCONF devices.

Security

lighty.io is implemented in Java, which is in nature a Type-Safe programming language. Type safety leads to more secure software than other software written e.g., in C/C++, while reaching a good performance. The model-driven approach and the source code generation also support software security.

These features minimize the possibility of error in the code by implementing the requirement of the verification of the input data from external applications and connected devices. Cyphering, authorization, and usage of these certificates are the matter of course.

Legacy and heterogeneous systems support

lighty.io implements the main SDN standards e.g., NETCONF, RESTCONF, YANG. Moreover, the legacy technologies that are already implemented in lighty.io makes SNMP southbound plugin possible. This shows that the capability of lighty.io being used not only in green-field deployments (implementing the system from scratch) but also brown-field deployments where it is needed to manage a heterogeneous set of networking devices.

Extensibility

As a software design principle, the model-driven approach speeds up and simplifies implementation of extensions with the architecture of lighty.io results in great extensibility. The architecture of the lighty.io defines Northbound – NB and Southbound – SB plugins implementations as a model-driven module.

NB & SB Plugins

NB plugins enable the communication of the controller with the upper layer applications. Such as dashboards, upper layer controllers, interDC orchestrators etc. The upper layer applications can be implemented as an external service or as a native module of the controller.

The upper layer applications mostly implement application logic, business logic, administration interfaces, data analytics, data transformation etc. NB plugins can be used to:

  • submit commands to the SDN controller,
  • send notifications to upper layers by the controller,
  • send telemetry data to upper layers by the controller,
  • monitor the controller by upper layers,
  • read the operational data of the controller and devices orchestrated by the controller,
  • the configuration of the controller itself or specific device orchestrated by the
    controller.

SB plugins implement protocols and technologies extending the SDN controller capabilities with new standards and technologies allowing connections of new network devices. SB plugins can be used for:

  • the configuration of networking devices,
  • fetching operational (state) data of the networking devices,
  • receiving telemetry data,
  • monitoring of devices,
  • submitting commands to the devices,
  • receiving notifications from devices.

Models and model-driven approach simplify the implementation of new plugins and upper layer applications because the usage of these models allows source code generation of classes (OOP construct) and related code which verifies the syntax and semantics of the data minimizes the probability of errors in implementation caused by human interactions.
