SD-WAN
Optimize Connections with Intelligent Routing
Digital Transformation with SaaS/Cloud
Why SD-WAN
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.
However, as more and more companies adopt SaaS and private/public cloud applications,
new technologies are needed to efficiently and dynamically route network traffic to
the central site or directly to the cloud.
SD-WAN is the solution to simplify this complex routing scheme. In addition to
traditional load balancing and failover functions, SD-WAN improves user experience
by specifically targeting 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.
With “Average” MOS, Network Admin will be able to understand the stability of quality
over past period.
“Active” Interface Quality, on the other hand, shows the interface quality right at the
moment.
MOS Compliancy
This percentage number shows the reliability of the connections. Ideally the connections should always be higher than the target MOS threshold.
Interface Quality From Macro to Micro
For every Interface on every CPE
If spotting any suspicious Interface quality result from Dashboard, Network Admin can
easily dive into details.
For each Interface on each CPE, Data usage, latency, Jitter, and Packet Loss are
recorded.
Intelligent VoIP Optimization
From the start of each VoIP call to the end, SD-WAN provides intelligent VoIP optimization.
Auto VoIP WAN
Based on the Interface quality, SD-WAN intelligently assign the best-quality WAN for VoIP traffics. So whenever making a new call, SD-WAN makes sure you are calling via the best WAN.
VoIP Live Failover
Although already sending via best-quality WAN, SD-WAN still keep monitoring on each live
call, and failover to secondary VoIP WAN if still meeting poor call quality.
Every call is logged with MOS score and sent Interface for Network Admin’s reference.
Application Visibility
Gain insights into the data usage across the entire network.
Usage Ranking
In-depth application insights with ranking by application and user ranking
Full Traffic Control with SD-WAN Route Policy
Application/Domain Route Policy
SD-WAN provides complete routing control by allowing Network Admin to specify the desired route for selected applications/domains to make sure the specific routing scenarios can be accomplished.
Failover/Failback
Failover to another interface when original interface offline,
and failback when possible.
Application Route Policy
Full Control of NAT and Routing
The matched sessions can be NATed or Routed, all under your control. Specially useful if having
private/MPLS WAN (requires routed) and direct Internet access (required NATed) at the same time.
In the following scenario, by creating 2 policies to different destinations, VoIP (SIP/RTP) from the
same IP phone in branch office can be routed via MPLS WAN when calling the other IP phone in HQ, and
NATed via 2nd WAN
to the Internet directly.
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.
