This technology can also be adapted to operate on packets at the network layer to improve application performance across WANs that have high-loss characteristics. With packet-level FEC, network equipment can reconstitute lost packets at the far end of a WAN link, avoiding delays that come with multiple round-trip retransmissions. This enables WANs to recover from packet loss due to a variety of network layer conditions, such as lossy links due to physical layer issues or&nbsp; bandwidth constraints. With packet level FEC, enterprises may see improvements in application performance depending on the specific application and the network conditions.</SPAN></P> <P>&nbsp;</P> <P><SPAN>Prisma SD-WAN will adaptively encode packet recovery information based upon the measured packet loss on the link.&nbsp; As loss increases additional recovery packets will be generated to ensure a successful recovery on the remote end of the Prisma SD-WAN VPN.&nbsp;&nbsp;</SPAN></P> <P>&nbsp;</P> <span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Fig 1_SD-WAN-Error-Correction_palo-alto-networks.png" style="width: 600px;"><img src="https://live.paloaltonetworks.com/t5/image/serverpage/image-id/53768iE022BDBBE71A92E1/image-dimensions/600x286?v=v2" width="600" height="286" role="button" title="Fig 1_SD-WAN-Error-Correction_palo-alto-networks.png" alt="Fig 1_SD-WAN-Error-Correction_palo-alto-networks.png" /></span> <P>&nbsp;</P> <P><I><SPAN>Note: </SPAN></I><EM>This feature is for preview only in the 6.2.2 Innovation ION software release and must be performed on devices on both ends of the Prisma SD-WAN VPN.
