Multapplied SD-WAN distributes packets across multiple circuits and aggregates the bandwidth of multiple circuits to form a virtual tunnel connecting a site to the Aggregator in the Service Provider Data Center.
Single Data Stream
The software on the Customer Premise Equipment manages packet distribution across the multiple circuits based on user-selectable algorithms. As the single data stream from the LAN is managed at a packet-level, the software can proactively change how each circuit in the tunnel is used, or whether it is removed completely from the tunnel to provide superior performance, stability, efficiency and uptime.
Dynamically Add Circuits
Dynamically add circuits back into the tunnel once performance thresholds return to normal. Packet-based balancing, plus Link Aggregation and Sub-second Same-IP failover together deliver highly reliable connectivity and continuous end-user access to remote applications, cloud services, and the Internet, all supporting session and business continuity.
Security at an Architectural-Level
In addition to optimizing circuit utilization and reliability, packet-based balancing provides security at an architectural level. Transmitting complete flows across an individual circuit makes data interception easier, whereas packet-distribution requires interception within the Service Provider data center or within the originating site and enhances security.
Our per-packet load balancing approach is unique in the SD-WAN marketplace. Other vendors have concentrated on balancing data flows, which creates a much slower failover environment and forces the vendor to deploy technologies like Forward Error Correction (“FEC”) to compensate for the variable quality of Internet circuits and is specifically used to improve the perceived quality of IP telephone calls.
FEC compensates for the packet loss or jitter that standard, broadband Internet circuits can create by duplicating the voice packets over multiple circuits. Instead of providing a single set of packets over the best circuit, FEC floods all circuits with multiple sets of packets with the hope that eventually all the required packets will reach the other end.
Network & Bandwidth Friendly
Our approach is a more network and bandwidth-friendly approach as the SD-WAN software can detect the quality of any of the circuits in the tunnel connecting a site to the network and ensure that packets are sent across the best-performing circuits at the time.
