Silverpeak

This section contains simulation results equivalent to those from the Silverpeak Powerpoint.

Here we showcase the difference between the FEC stable, Reed-Solomon Codes, and Rely in terms of

• Reliability (Residual Packet Loss)
• Bandwidth-usage (Repair Rate / Coding Rate)
• Per-Packet-Delay (Latency)

The Reed-Solomon Codes represent what we call Legacy Codes. It was designed/invented in 1960, but is still widely used.

What do we wish to show?

We wish to highlight that using a Legacy Code like Reed-Solomon, there will be some trade-off in terms of the three parameters..

You can minimize two of them, but the third will be sacrificed in the process.

This is not the case with Rely, and we expect the results to reflect this.

We have therefore simulated a setting with code parameters (repair interval, repair target) = (5, 1) and (10, 1) respectively.

In the (5, 1) setting we crank up the packet loss slightly, while a (10, 1) will be a fitting setting for most common channels.
