Fec packet loss

WebOur SD-WAN system (Silverpeak) alerts us when any WAN circuit at our branch offices begins experiencing packet loss. About a few months into our deployment we basically started ignoring it. Because the users don’t notice anything happening. WebAdaptive Forward Error Correction (FEC). Silver Peak uses packet-level FEC to reconstitute lost packets at the far end of a WAN link, avoiding delays that come with multiple round-trip retransmissions. This enables WANs to easily recover …

Using Forward Error Correction to Mitigate Packet Loss

WebIf FEC is applied within a packet or appended to individual packets, in cases where packets are not just erroneous but are lost completely during transmission (e.g., over a congested internet connection), the correction capability of the code is lost. Instead, it is beneficial to apply FEC across a number of packets, as shown in Fig. 11.10.
