Traditionally most business applications were running on the private servers in the HQ, and MPLS that routes all traffics to the center site made this model quite efficient.
However, with adopting more and more SaaS and private/public cloud applications, we need new technologies that can efficiently and dynamically route different traffics either to the center site or to the cloud directly.
SD-WAN is the solution to make the complex routing scheme simple and intuitive. Based on traditional load balancing and failover functions, SD-WAN further improves user experience by focusing on interface and application quality.
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.
This percentage number shows the reliability of the connections. Ideally the connections should always be higher than the target MOS threshold.
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.
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.
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.
In-depth application insights with ranking by application and user ranking
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 to another interface when original interface offline, and failback when possible.
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.
