SDN and NFV

Software Define Networking (SDN), Network Function Virtualization (NFV) and White-box based solutions have transformed the ways of telecom service delivery. Aricent offers a wide range of SDN enabled cloud virtualization solutions that accelerate application deployment and delivery, through policy-enabled workflow automation. Our SDN & NFV software frameworks in conjunction with consortium-based open APIs, open design and open source solutions lead to faster development of differentiated and profitable solutions.

Software Defined Networking (SDN)

SDN decouples the control and data planes to enable limitless possibilities in programming the switch as per network needs. By optimizing and centralizing innovative applications, SDN offers unprecedented OpEx and CapEx savings. Aricent provides comprehensive software frameworks and product engineering services spanning all three layers of SDN—the infrastructure, the controller and the application layer. Our SDN software offerings help Communication Equipment Providers (CEPs), Independent software Vendors (ISV) and semiconductor vendors to optimize R&D costs and accelerate the time-to-market for innovative SDN solutions.

Aricent’s frameworks for SDN include:

  • SDN Controller Applications
  • OpenFlow Client
  • Hybrid Routing and Switching Framework

SDN Controller Applications

Our applications offer SDN-based solutions for challenges faced in datacenter, transport and carrier networks today. These applications are pre-integrated on popular controller platforms and can easily be ported to any custom controller. The controller platforms may support different southbound interfaces, such as NETCONF,OpenFlow or others. Several protocols from our proven ISS framework have also been repurposed as controller applications. The SDN applications are customizable and thus offer differentiated applications on a choice of controller platforms, accelerating time-to-market and reduced R&D costs.

OpenFlow Client

Aricent’s OpenFlow Client (OFC) is a portable implementation of the OpenFlow client functionality and is compliant with version 1.3.1 of the OpenFlow Switch Specification. OFC is platform agnostic and is pre-integrated on leading silicon platforms (e.g. Broadcom OFDPA). OFC is also pre-integrated with Aricent’s industry leading ISS solution that can be leveraged to build hybrid OpenFlow switches and routers.

Hybrid Routing and Switching Framework

Our Hybrid Routing and Switching Framework supports both OpenFlow based and traditional L2/L3-based routing and switching. This framework is compatible with a hybrid switch implementation, and is pre-integrated on leading silicon platforms. It provides:

  • Generic APIs for easy integration with existing software architecture
  • Comprehensive set of MIB objects for management through SNMP& NETCONF
  • Support for all OpenFlow messages and configuration through the OF-Config Interface

Network Function Virtualization (NFV)

As defined by the European Telecommunications Standards Institute (ETSI), Network Function Virtualization (NFV) aims to transform service provider networks by implementing virtualized network functions that run over industry-standard server hardware—consolidating many network equipment types onto industry-standard high volume equipment.

Aricent’s NFV solution leverages the large portfolio of technology framework to realize customizable solutions and accelerated the time-to-market factor. The pre-integrated saves significant R&D spend.

  • Control Plane Software
  • Data Plane Software
  • Open source based platform software to address the performance and service fulfillment challenges (OVS Offload).
  • Leveraged open source based Management and Orchestration (MANO) solutions for VNF Service Life Cycle management.
  • Pre-integrated Software Framework e.g.
    • vCPE Solution
    • vRouter

Virtual Network Functions

Aricent’s Virtual Network Function (VNF) leverages its proven and deployed control plane software (e.g. ISS is a L2/L3 switching and routing solution that has been deployed in more than 100 commercial networking products). These have been re-architected so that it can be deployed in cloud based platform.

 Fast Path Accelerator

Aricent’s Fast Path Accelerator (FPA) leverages the power of multi-core architecture in a virtualized switch or virtualized network application, to implement a high-performance switching and forwarding logic. FPA is an implementation of OpenFlow pipeline processing requirements given in Open Networking Foundation (ONF) OpenFlow specification version 1.3.1. FPA is implemented on Intel’s Data Plane Development Kit (DPDK) for multi-core platforms and has been extended for ARM based SoC.The FPA’s architecture is modular with flexible building blocks that can easily be extended to other multi-core switch platforms. The building blocks also facilitates the plugging-in of custom modules. Besides implementing the OpenFlow Pipeline, the FPA also implements the traditional switching and routing pipelines.

Platform + Orchestrator Software

Aricent’s NFV solutions leverages the open source Linux based KVM hypervisor to implement the NFV Infrastructure layer (NFVI) and the OpenStack based Management and Orchestration and OPNV Platforms.

Pre-integratedSolution: vCPE

Aricent’s cloud-based vCPE is a software framework that virtualizes several CPE network functions such as Firewall, Layer 3, NAT, DHCP, Policy Management etc. This framework can be leveraged by our customers to build the full ETSI NFV standards-based vCPE solutions. The solution uses Aricent’s widely deployed and industry-leading Intelligent Switching Solution (ISS) as the control plane and the Fast Path Accelerator (FPA) while leveraging the open source based platform and orchestrator platform.
