The invention discloses an IPoE (IP (internet protocol) over Ethernet) user offline automatic detection system and an IPoE user offline automatic detection method. The method includes that EOC (Ethernet over Coax) terminal equipment is powered on prior to being registered to an EOC local side; the EOC local side reports the EOC terminal and user information to a CNU / CBAT (coaxial cable broadband access terminal) controller; the CNU / CBAT controller distributes IP addresses to users and replaces the EOC terminal to register to an AAA (authentication, authorization and accounting) server; when the EOC terminal is powered down, the EOC local side detects and sends user offline messages to the CNU / CBAT controller in real time; and the CNU / CBAT controller replaces the EOC terminal to send DHCP (dynamic host control protocol) Release information and recover the IP addresses. By the IPoE user offline detection method, management on abnormal user offline by the IPoE technology is simplified in an EOC system, and operators are guaranteed to authorize and count more rationally.

A high-performance, scalable and drop-free data center switch fabric and infrastructure is described. The data center switch fabric may leverage low cost, off-the-shelf packet-based switching components (e.g., IP over Ethernet (IPoE)) and overlay forwarding technologies rather than proprietary switch fabric. In one example, host network accelerators (HNAs) are positioned between servers (e.g., virtual machines or dedicated servers) of the data center and an IPoE core network that provides point-to-point connectivity between the servers. The HNAs are hardware devices that embed virtual routers on one or more integrated circuits, where the virtual router are configured to extend the one or more virtual networks to the virtual machines and to seamlessly transport packets over the switch fabric using an overlay network. In other words, the HNAs provide hardware-based, seamless access interfaces to overlay technologies used for communicating packet flows through the core switching network of the data center.
