Silver Peak: SD-WAN with Packet-by-Packet Load Balancing and Error Correction

An Intellyx Brain Candy Brief

Silver Peak is one of many vendors in the burgeoning software-defined wide-area networking (SD-WAN) market. Superficially, it shares the same value proposition as all the players in this space, as it gives customers the ability to configure, prioritize, and manage wide-area network connections among geographically distributed locations, and between those locations and cloud services.

Silver Peak’s most important differentiator, however, is its ability to make load balancing decisions on a packet-by-packet basis. While other SD-WAN vendors prioritize traffic by type or by message, for example, send video over the Internet but point-of-sale transactions over the private MPLS link, Silver Peak can break up individual messages and route them piecemeal for the best real-time performance.

Furthermore, the vendor offers error correction it bases on ‘erasure coding,’ which uses a checksum-based approach for reconstructing lost packets, similar to the way that RAID storage systems work.

The end result: virtually no lost packets, and overall real-time performance that can actually exceed the performance of each of the individual network connections, even when all of the network connections are simultaneously experiencing slowdowns or other issues.
