SDN NFV

The emergence of Network Function Virtualization (NFV) and Software-Defined Networking (SDN) has brought closer to reality each operator's quest to create and orchestrate end-to-end, virtual connectivity services for their subscribers.

Intracom Telecom, provides a number of applications and tools enabling Communication Service Providers (CSPs) to deploy virtualized access services on-demand, minimizing time-to-market and upfront investments.

Virtualized WiFi

Use Case: Smart Lighting with Virtualized Wi-Fi

Intracom Telecom has developed a state-of-the-art innovative solution that allows CSPs to collaboratively share & monetize a common Wi-Fi infrastructure, while maintaining service and brand differentiation.

This first fully ETSI NFV-compliant virtualized Wi-Fi solution seamlessly integrates with and virtualizes both indoor and outdoor access points within a fully customizable cloud environment. At a click of a button each hosted operator can choose to deploy virtual network functions (VNFs) between either a pre-configured, out-of-the-box library of VNFs or any other third-party VNF vendor.

Through NFV-enabled Wi-Fi access points, deployed across a Smart City, multiple CSPs can simultaneously utilize virtual slices as if each of them was the sole owner of the respective physical resources.

With Intracom Telecom's virtualized Wi-Fi solution, multiple Wi-Fi vendors can unify all Access Points and provision vendor's controllers or directly control access points. In this way, CSPs can collaboratively share & monetize a common Wi-Fi infrastructure through Wi-Fi infrastructure unification.

Software Defined Carrier Ethernet

Intracom Telecom contributes to the collaborative open source OpenDaylight project as Silver Sponsor and innovates in the OpenDaylight community to deliver MEF-specified Ethernet services over the SDN architecture.

MEF services implemented include:

  • Ethernet Private Line (EPL)
  • Ethernet Virtual Private Line (EVPL)
  • Ethernet Private LAN (EP-LAN)

Northbound interface

  • Configuration of MEF services, Bandwidth profiles, and Layer 2 control plane profiles
  • Report on state of MEF services and their utilized paths (nodes and links)

Graphs algorithms

  • Use of Dijkstra algorithm for shortest path calculations
  • Computation of alternative paths for fast failover
  • Computation of Minimum Spanning Trees

Extra Functionality

  • Fast Failover after link/node failure without the intervention of the SDN controller (<50 msec)

Transport mechanism

  • QinQ

NFV Accelerator

Intracom Telecom has developed an NFV Accelerator which is an NFV stack add-on enabling VNF performance optimization and energy savings.

Within NFV Accelerator, the following policies are being targeted:

  • Data Flow Aware placement (DFA)
  • Memory Access Aware placement (MAA)
  • I/O Aware placement (IOA)
  • SMT (Hyperthreading) Aware placement (SMTA)
  • Power Aware placement (PA)

Open Source SDN Projects and Free NFV Stack

SDN & NFV open source

While conducting advanced R&D on SDN & NFV domains, Intracom Telecom is donating to the international development community through Open Source which comprises a collection of open source tools related to SDN and NFV.

The entire set of tools can be downloaded from GitHub at http://intracom-telecom-sdn.github.io/
