![]() In some cases technical support may able to manually make changes to customers' sync profile to set either Fast path or Interleave mode. How to change from Interleave to Fast path to reduce latency: - if your line syncs better than the speed you are provisioned for, it usually syncs using fastpath - if there are no errors on the line, and no recent/frequent reboots the automated system may switch you to fast path from interleave mode. ![]() Interleave mode may be imposed automatically by the condition of your line (high error rates, low upstream SNR), software optimizations by your provider to improve DSL stability, or by hardware/firmware upgrades at the DSLAM. ![]() Both the CO and CPE have to use the same setting, it may be the default used by your CO, or they may be using an automated sync optimization scheme. This Interleave process introduces a few ms delay (10-20ms) compared to Fast path, that may be an issue for gaming. It rearranges bits before they are transmitted so that errors can be detected and possibly corrected. Interleave helps resolve errors on longer loops and noisy lines. if the error rate creeps up the CO/DSLAM may automatically impose Interleave mode to cope with that. Kernel will try to use fast path unless any of the above conditions are. 6WINDGate Fast Path provides a fast packet processing framework (IP forwarding, IPinIP. It indicates the packet is dropped in the IP receiving path and due to kernel. Interleave is an error correction scheme. Convergence on IP networks has not been without its challenges. Routers inspect each packets IP header to identify where to send them. The following protocols help data packets find their way across the Internet: IP: The Internet Protocol (IP) specifies the origin and destination for each data packet.
