Virtualized Network Services and SD-WAN 2.0

VSP enables large enterprises and Communication Service Providers (CSPs) to offer Virtualized Networks Services (VNS) offering the industry’s first SD-WAN 2.0 capability.

With SD-WAN 2.0 as the enabling technology
enterprises can solve the following challenges:

img platform 1

The Multicloud Challenge

Business applications are changing rapidly, and the workloads that serve them have moved beyond private data centers. Compute resources and associated cloud services are exploding, and traditional enterprise network boundaries have expanded into the public cloud, branch locations, and intelligent edges. You need a single end to end SD-WAN solution that provides a flexible multicloud strategy to address this new reality.

Scaling Challenge

The scaling requirements in this new era of cloud automation are staggering. Thousands of applications, hundreds of locations, a multitude of cloud services and distributed compute, serving mobile users, IoT-enabled people and things will create a scaling issue that needs to be addressed. You need an SD-WAN solution that is built for this level of scale.

The Security Challenge

The era of cloud-based architectures is upon us and traditional security measures are not enough to protect your network from end to end within its perimeter. The massive volume and “ephemeral” nature of today’s applications create a new threat landscape that can infect your network from within laterally and a new set of software-defined security measures need to be implemented.

The Branch Virtualization Challenge

The sprawl of dedicated branch devices to support network functions like L7 FW, WAN optimization, IPS/IDS, etc. is operationally difficult to manage and in the era of virtualization, enterprises are moving toward hosting these functions as a VNF on a uCPE. The right SD-WAN solution can provide a holistic approach to securely managing the connectivity of these VNFs and uCPEs across all locations using centralized policies.

The remote worker challenge

Enterprises need to find ways to embrace the growing number of home teleworkers and mobile users through a common policy and control framework

Virtualized Cloud Services

Virtualized Cloud Services (VCS) is the data center and cloud networking framework enabled by Nuage Networks Virtualized Services Platform (VSP). It enables CSPs and their Telco Cloud deployments as well as large enterprise data center customers to automate the configuration, management and optimization of virtual networks, including security services that provide tenant isolation and access controls to individual applications and workloads.

VCS is a non-disruptive software-defined networking (SDN) overlay for all virtualized and non-virtualized server and network resources. It is transparent to the underlying physical infrastructure and provides a complete cloud networking framework that requires no specialized hardware. VCS can be deployed in any mixed environment including Docker containers, multi-hypervisor Virtual Machines (VMs), or bare metal servers.

VCS helps eliminate the constraints and complexity of cloud networking so that CSPs and enterprise data centers can:

Flexibly support any open and mixed environments

Reduce integration and compatibility issues by supporting open-source products and tools and any mixed environment (containers, VMs, and bare metal).

Make network infrastructure programmable and consumable

Make the network infrastructure programmable and consumable for the upcoming massive scale and latency requirements of 5G and IoT.

Apply granular security policies

Apply granular security policies in an intelligent, consistent and provable way across the entire cloud.

scalable

Make network infrastructure programmable and consumable

Make the network infrastructure programmable and consumable for the upcoming massive scale and latency requirements of 5G and IoT.

dynamic

Make the network dynamic and optimized

Make the network as dynamic as the compute resources themselves by automating and optimizing all aspects of the network.

Virtualized Service Platform (VSP)

Nuage Networks Virtualized Service Platform (VSP) is the common platform where both Virtualized Cloud Services (VCS) and Virtualized Network Services (VNS) are offered. VCS is Nuage Networks data center SDN solution. VNS is Nuage Network’s SD-WAN 2.0 solution.

Network Services Gateway (NSG)

The Network Services Gateway (NSG) constitutes the network-forwarding plane for VNS. The NSG encapsulates data traffic, enforcing Layer 2 to Layer 4 network policies as well as establishing Layer 2 or Layer 3 overlay VPNs as defined by the VSD. The NSG family also supports built-in Wi-Fi access as well as LTE uplink as well as other inherent built-in advanced services.

Virtualized Service Directory (VSD)

The Virtualized Services Directory (VSD) is a programmable policy and analytics engine. It provides a flexible network policy framework that enables network administration teams to define, apply, and enforce business policies across the network service in a user-friendly manner. The VSD also offers a multi-tenant enterprise portal that enterprise customers can use to visualize, configure, maintain their network.

Network Services Gateway (NSG) - v

The NSG–v is the virtualized software image of the VSG and can be deployed in any x86-based virtualized environment and is the software that is deployed in public clouds to extend SD-WAN 2.0 visibility and control.

Virtualized Service Controller (VSC)

The Virtualized Services Controller (VSC) is the industry’s most powerful SDN controller. It functions as a centralized and robust network control plane for the network services, maintaining a full view of the network and service topologies. Through the VSC, virtual routing and switching constructs are established to program the network-forwarding plane.

Virtual Routing & Switching (VRS)

Virtual Routing & Switching (VRS) is a software agent that resides in a virtualized server environment of a data center that serves as a virtual endpoint for network services. Through the VRS, changes in the compute environment are immediately detected, triggering instantaneous policy-based responses in network connectivity to meet the needs of applications.
