Software-defined networking (SDN) employs software rather than networking appliances to provision and manage network services, leading to more programmable, scalable, dynamic application delivery and greater mobility. SDN automates configuration and provisioning without hardware constraints, monitoring and adapting the network to best serve demand.

Aruba SD WAN, managed via Aruba Central simplifies WAN routing, reduces costs and  delivers increased visibility and control over Internet traffic.

Key features include:

  • Integrating SD-WAN with existing management tools. Aruba Central provides cloud management for SD-WAN, WLAN, and LAN to provide IT with end-to-end network visibility.
  • Optimize traffic with role-based awareness, via features such as policy-based routing for 2600+ applications; and dynamic path selection, enabling granular decisions to optimise branch experience and performance.
  • Simplicity at scale, integrate SD-WAN with WLAN and LAN under a software defined network architecture to improve management and visibility.
  • Secure network access and control, offering improved WAN intelligence and security with context into users and devices at every branch. Centralised policy definitions for WAN, WLAN, and LAN deliver consistent branch experiences securely.
  • Up to 6 Gbps of stateful firewall throughput for each branch deployment
  • Integration with web security gateways and on- premises security firewalls

 

Core components:
ARUBA CENTRAL - NETWORK MANAGEMENT
Cloud-based policy, configuration, and monitoring capabilities simplify and improve deployment, performance and maintenance. Simple-to-use dashboards provide visibility and flexible options for deploying and configuring Aruba branch and headend and gateways.

BRANCH GATEWAYS
Aruba 7000 Series hardware- based appliances support SD-WAN deployments for all sizes of branch, supporting multiple connection types including WAN, WLAN, and LAN interfaces. Features policy-based routing, an application and user aware firewall, WebCC for content filtering, and WAN compression. For High Availability (HA), can be deployed in active/ standby or active/active mode.

HEADEND GATEWAY
Aruba 7200 Series appliances are used as headend gateways, or VPN concentrators (VPNC), to terminate branch gateway connections. They scale to meet the needs of hundreds or thousands of branch networks. In a typical dual hub-and-spoke model, For HA, multiple headend gateways can be deployed at a single site or pairs of headend gateways can deployed at multiple sites.

EXTENDED FEATURES

Stateful Firewall – Enforces consistent user, device, and application policies across WLAN, LAN, and WAN.

Dynamic Segmentation – All traffic is tunnelled to a branch gateway for inspection, thereby simplifying policy enforcement and improving consistency of user and IoT devices.

Zero-touch Provisioning – Hardware gateways factory-shipped and deployed onsite with Aruba ActivateTM.

White Glove Device Onboarding – Allows on-site personnel to use a mobile app to onboard gateways.

Application Visibility and Control – AppRFTM continuously evaluates and optimizes performance for over 2,600 applications to ensure the highest possible Quality of Service (QoS)

Policy-based Routing (PBR) and Dynamic Path Steering (DPS) Traffic can be routed across multiple private or public WAN uplinks based on application health or type, user role, or destination.

Web Content Filtering – Classifies websites by content category and their reputation rating, can easily block, apply QoS, bandwidth-limit, mirror, and log web content.

Unified Communications and Collaboration (UCC) Visualize and troubleshoot networks based on call quality metrics such as MOS, latency.

Third-party security gateway and firewall support – For advanced malware or antivirus protection.
