Dear Forum,

someone here who already implemented isochronous data transfer between PCIe-endpoints?

As I know, the PCIe-switch between the endpoints must support the following:

- Minimum 2 VCs (virtual channels)
- TBWRR (time based weighted round robin)

But what about the endpoints? Do I also need minimum 2 VCs to transfer isochronous data from endpoint-A to endpoint-B?
