SYSTEM AND METHOD OF SENDING PCI EXPRESS DATA OVER ETHERNET CONNECTION

摘要

According to certain aspects, the present invention relates to a system and method of sending PCI Express video data over a lower speed Ethernet connection. In embodiments, a system according to the invention includes bridges at either end of an Ethernet connection that is disposed between a PCIe host and a PCIe device. According to aspects of the invention, the slower Ethernet connection can be used by forcing the faster PCIe link to operate at a slower rate than is possible, forcing a PCIe device with a large number of lanes to use only a single lane, forcing a PCIe link to use the shortest possible packet size and/or controlling the time when UpdateFC DLLP packets are sent.
