Optimize Connections with Intelligent Routing
Traditionally, many business applications were hosted on private servers located in the company’s headquarters, and the use of MPLS to route all network traffic to the central site made this model highly efficient.
Overview
SD-WAN
Optimize Connections with Intelligent Routing
Digital Transformation with SaaS/Cloud
Why SD-WAN
As more and more companies adopt SaaS and private/public cloud applications, new technologies are needed to route network traffic efficiently and dynamically, either to the central site or directly to the cloud.
SD-WAN simplifies this complex routing. Beyond traditional load balancing and failover, SD-WAN improves the user experience by focusing specifically on interface and application quality.
Auto VPN
DrayTek SD-WAN solution provides the easiest way to setup VPN tunnels from scratch.
Hub-and-Spoke
- Select the Hub device
- Done! VigorACS will automatically create one IPSec tunnel from each Spoke to the Hub.
Full Mesh
- Done! VigorACS will automatically design and create one IPSec tunnel between each router.
Interface Quality At a Glance
Interface MOS
Wired WAN, Wireless WAN (including wireless 2.4G/5G WAN, LTE WAN, and USB WAN), and VPN quality are monitored 24/7.
The “Average” MOS shows the Network Admin how stable quality has been over a past period.
“Active” Interface Quality, on the other hand, shows interface quality at this moment.
MOS Compliancy
This percentage shows the reliability of the connections. Ideally, connections should always stay above the target MOS threshold.
Interface Quality From Macro to Micro
For every Interface on every CPE
If the Dashboard shows a suspicious interface quality result, the Network Admin can easily drill down into the details.
Data usage, latency, jitter, and packet loss are recorded for each interface on each CPE.
Intelligent VoIP Optimization
From the start of each VoIP call to the end, SD-WAN provides intelligent VoIP optimization.
Auto VoIP WAN
Based on interface quality, SD-WAN intelligently assigns the best-quality WAN to VoIP traffic, so every new call goes out over the best WAN.
VoIP Live Failover
Even after a call is sent over the best-quality WAN, SD-WAN keeps monitoring each live call and fails over to a secondary VoIP WAN if call quality is still poor.
Every call is logged with its MOS score and the interface it used, for the Network Admin’s reference.
Application Visibility
Gain insights into the data usage across the entire network.

Full Traffic Control with SD-WAN Route Policy
Application/Domain Route Policy
SD-WAN gives the Network Admin complete routing control by letting them specify the desired route for selected applications/domains, so specific routing scenarios can be accomplished.
Failover/Failback
Fails over to another interface when the original interface goes offline,
and fails back when possible.
Application Route Policy
Full Control of NAT and Routing
Matched sessions can be NATed or routed, entirely under your control. This is especially useful when you have a private/MPLS WAN (which requires routing) and direct Internet access (which requires NAT) at the same time.
In the following scenario, two policies with different destinations let VoIP (SIP/RTP) traffic from the same IP phone in a branch office be routed over the MPLS WAN when calling another IP phone at HQ, and NATed over the 2nd WAN directly to the Internet.
Components and Topology
Edge Routers Providing Edge Computing
- Edge routers are physical routers installed in HQ and Branches.
- Router models selection for different WAN types, including DSL and LTE.
- Establishing VPN tunnels (IPSec by default) from branches to HQ to form Hub-n-Spoke or Mesh topology.
- Receiving SD-WAN configurations from VigorACS 3, performing edge computing according to SD-WAN policies, and uploading data to VigorACS3 for monitoring.
VigorACS 3 Server as Orchestrator
- VigorACS 3 is the central software where network administrators perform configurations, provisioning, and monitoring activity.
- Multitenant capability made xSP services easy.
