Since timing skew over a parallel bus can amount to a few nanoseconds, the resulting bandwidth limitation is in the range of hundreds of megahertz. PCI Express uses credit-based flow control. The advantage of this scheme compared to other methods such as wait states or handshake-based transfer protocols is that the latency of credit return does not affect performance, provided that the credit limit is not encountered. The lane count is automatically negotiated during device initialization, and can be restricted by either endpoint. 704 705 706 707 708 704 705 706 707 708
