Intel 82599 Dual 10GB Ethernet
The 82599 provides a high-speed CPU path into the switch fabric for both data and switch management . The
interface to the switch consists of dual-channel XAUI (IEEE 802.3ae). The 82599 connects via x8 Gen2 PCIe to the
PEX8624 PCIe switch and from there to the CPU. As previously mentioned, the 82599 also supports IEEE 1588
precision time protocol (PTP) by time stamping in-coming and out-going data packets.
