On my last visit to RMAF, I have seen few Ethernet switches that were focusing on jitter control with their onboard OCXO circuit and separate linear power supply.
I don't understand how a reclocking of the switch will help. The stream is packetized and the master clock is in the final interface, not in the switch.
The LPS will definitely help though, and it must have DC common tied to earth ground. This reduces leakage. This makes the biggest difference.
