On-premises deployment, on the other hand, provides organizations with greater control over data, compliance, and integration with existing security infrastructure. It is suitable for highly regulated industries or organizations with strict data residency requirements. The on-premises orchestrator offers similar functionalities as the cloud version but requires dedicated hardware or virtual machines within the organization’s data center.

Configuring the VMware SD-WAN orchestrator involves setting up policies such as traffic steering, application prioritization, and security rules. Example CLI snippets for policy configuration may include commands like:

set policy application-priority  
set traffic-steering   

This centralized management simplifies large-scale deployments and ensures consistent policy enforcement across all sites, whether managed via cloud or on-premises. For detailed step-by-step tutorials, visit Networkers Home Blog.

VeloCloud Gateways — Cloud Gateways & Multi-Path Optimisation

VeloCloud gateways serve as the critical points that facilitate traffic routing, security, and optimization between the WAN endpoints and cloud or data center resources. These gateways are strategically deployed in the cloud or on-premises to ensure seamless connectivity, security, and multi-path traffic management. VMware VeloCloud SD-WAN uses multiple gateway types, including edge gateways, regional gateways, and cloud gateways, to optimize performance.

Cloud gateways are typically deployed at major cloud provider locations such as AWS, Azure, or Google Cloud. They act as termination points for encrypted tunnels, providing secure and reliable paths for inter-site communication and cloud access. These gateways support dynamic path selection, ensuring optimal routes are chosen based on real-time network conditions, latency, and application requirements.

Multi-path optimization (MPO) is a key feature of VeloCloud SD-WAN gateways. It enables traffic to be split intelligently across multiple links, such as broadband, LTE, or MPLS, to maximize throughput and reduce latency. For example, real-time applications like VoIP or video conferencing benefit significantly from MPO by reducing jitter and packet loss.

Configuration of gateways involves setting up routing policies, security rules, and link monitoring parameters. For instance, a typical configuration snippet for a gateway might include:

configure gateway 
set link monitor   
set route  

VeloCloud gateways also support network address translation (NAT), firewall, and VPN functionalities, which are integrated into the overall SD-WAN fabric. This reduces the need for additional hardware and simplifies network architecture.

Broadcom SD-WAN hardware solutions often integrate with VeloCloud gateways, enhancing performance and security. To explore gateway deployment strategies, visit Networkers Home's Cisco SD-WAN courses.

Edge Devices — Hardware, Virtual & BYOD Options

The edge device in VMware VeloCloud SD-WAN refers to the physical, virtual, or Bring Your Own Device (BYOD) endpoints that connect branch sites to the SD-WAN fabric. These devices are responsible for establishing tunnels with gateways, executing traffic policies, and providing local security functionalities. The versatility in edge device options allows organizations to tailor deployments based on site requirements, size, and budget.

Hardware Edges: Physical appliances like VeloCloud Edge devices are purpose-built for enterprise environments. They come with dedicated processors, multiple interfaces, and integrated security features. Examples include the VeloCloud Edge 1100 and 2100 series, which support high throughput and advanced security capabilities. These devices are typically deployed in branch offices, data centers, or remote sites requiring robust performance.

Virtual Edges: For virtualized environments, VMware offers VeloCloud Virtual Edges that run as VM instances on hypervisors like VMware ESXi, Hyper-V, or KVM. Virtual Edges are ideal for smaller sites, data centers, or cloud deployments where hardware deployment is impractical. They provide similar features as physical appliances, including tunnel termination, policy enforcement, and security.

BYOD & Software Options: BYOD (Bring Your Own Device) options such as client VPNs or software-based agents offer flexibility for remote workers or mobile users. These agents establish secure tunnels back to the SD-WAN fabric, ensuring consistent security and policy enforcement across all endpoints.

Configuration of edge devices involves setting up interfaces, tunnel parameters, and security policies. For example, configuring a physical VeloCloud Edge may involve CLI commands like:

configure interface gigabitEthernet0/1
set ip address 192.168.1.1/24
configure tunnel
set remote peer 
set encryption aes-256

Edge devices also support zero-touch provisioning (ZTP), enabling rapid deployment without manual configuration at each site. This reduces deployment time and errors, making SD-WAN adoption scalable across large enterprises.

Dynamic Multi-Path Optimisation — DMPO Technology

Dynamic Multi-Path Optimization (DMPO) is a cornerstone feature of VMware VeloCloud SD-WAN, enabling real-time traffic steering across multiple links based on network conditions. Unlike static routing, DMPO continuously monitors link health, latency, jitter, and packet loss, dynamically adjusting traffic flows to ensure optimal application performance and user experience.

DMPO employs algorithms that analyze real-time metrics and make intelligent decisions for traffic distribution. For example, VoIP traffic can be prioritized over less sensitive data, and high-latency links can be bypassed for time-critical applications. The technology uses techniques such as forward error correction (FEC), packet duplication, and adaptive path selection to mitigate packet loss and jitter.

Implementation involves configuring link monitors and path preferences within the VMware SD-WAN orchestrator. An example setup might include setting thresholds for latency or packet loss, triggering path adjustments when exceeded:

set link monitor name WAN1 threshold latency 50ms
set link monitor name WAN2 threshold packet-loss 1%
set path preference high-priority  via WAN1
set path fallback  via WAN2

DMPO's efficacy is evident in scenarios like multi-site enterprise connectivity, where links such as LTE and broadband are combined. During a fiber outage, traffic can seamlessly shift to LTE, maintaining application continuity without manual intervention.

Real-world examples include deploying DMPO for critical cloud applications like Microsoft 365 or AWS workloads, where performance consistency is vital. VMware VeloCloud SD-WAN's DMPO significantly reduces latency, jitter, and packet loss, leading to improved user productivity and reduced operational overheads.

Business Policies & Traffic Steering Rules

Central to VMware VeloCloud SD-WAN's effectiveness are its business policies and traffic steering rules. These enable granular control over how different types of traffic are prioritized, routed, and secured across the WAN fabric. By defining policies, organizations can ensure critical applications receive the necessary bandwidth and low latency, while less important traffic is relegated to secondary links.

Traffic steering rules are configured based on application type, user identity, source/destination IP, or even time of day. For example, office VoIP calls can be assigned the highest priority and routed exclusively over low-latency links, whereas bulk data transfers can be scheduled during off-peak hours.

Policy configuration involves defining rules within the VMware SD-WAN orchestrator, often through GUI dashboards or CLI commands. An example CLI snippet might include:

set policy application-policy VoIP
set application-traffic  priority high
set route  
set security  permit

Further, policies can be tied to user groups or device types, ensuring role-based access and control. For instance, remote workers accessing critical SaaS applications might be routed through secure VPN tunnels, while guest users are isolated via segmentation policies.

Implementing these policies requires detailed planning and understanding of application SLAs. VMware VeloCloud SD-WAN also supports AI-driven policy recommendations, simplifying optimization. For advanced policy design examples, see Networkers Home Blog.
