Sat-Link: IP-Layer Forward Acceleration for Satellite Link Optimization
Sat-Link (CloudWing) Satellite Internet Access Acceleration System — High-performance FEC acceleration designed for satellite communications. Combines low-level IP packet encoding with Forward Error Correction to deliver rock-solid link stability and eliminate retransmission delays in high-latency, weak network environments.
Bandwidth utilization improved by ~70%
in 10% packet loss environments
FEC redundancy automatically converges to 0
when network quality is good
Transparent access
zero configuration for end-user devices
Why Traditional TCP Fails on High-Latency GEO Satellite Links
In high-latency GEO satellite environments (typically ~600ms RTT), standard IP network protocols suffer massive throughput degradation. Traditional TCP wastes precious bandwidth on retransmissions, leaving you with only a fraction of the throughput you paid for.
During rain fade, web pages won't load
File transfers interrupt frequently, causing productivity losses and frustrated users.
Video feeds frequently stutter
Monitoring screens display artifacts and freeze, compromising surveillance effectiveness.
Only half the actual throughput
You paid for 10Mbps bandwidth, but retransmissions consume half your capacity.
How Dynamic Forward Error Correction (FEC) Optimizes Satellite IP Traffic
Sat-Link implements dynamic FEC (Forward Error Correction) to reconstruct dropped packets in real time, optimizing link capacity without relying on slow TCP retransmissions. FEC coding technology adds redundant data to transmissions. When packets are lost, the receiver can reconstruct them from the redundancy without waiting for retransmissions.

Data Speaks
Simulated GEO satellite link test (600ms RTT)
Bandwidth utilization improved by ~70% under 10% packet loss rate
In rain fade (high packet loss) scenarios, web page loading speed improved up to 2.5x, with stable loading times and no significant jitter
When link quality is good, system overhead is nearly zero, does not slow down existing speeds
Test results based on simulated environment; actual performance may vary depending on link conditions.
