摘要： One embodiment disclosed relates to a method for a switch to respond to a new client. A new client is detected at a port of the switch. The switch temporarily assigns the port to be an untagged member of a virtual local area network (VLAN) which is configured for unauthorized clients. Initialization services are provided to the new client via the unauthorized-client VLAN. The new client may be authenticated by way of an authentication session using the unauthorized-client VLAN. If the new client is authenticated, then the untagged membership of the port in the unauthorized-client VLAN is dropped, and the port is assigned to be an untagged member of a specified VLAN.

摘要： A system and method for implementing a VM to identify a data packet for transmission, the data packet including a QoS the data packet is to receive as compared to another QoS that another data packet is to receive. The system and method further includes a SNIC to pull the data packet from the VM based upon the QoS the data packet is to receive. The system and method may also include a link scheduler module to transmit the data packet based upon the QoS the data packet is to receive. The system and method may also include a receiver to receive a management instruction from a network management device, the management instruction to dictate the QoS the data packet is to receive based upon a SLA.

摘要： A network switch includes a predictor using data in a packet to predict a flow for the packet. A forwarding engine forwards at least a portion of the packet on a switch fabric to an egress port in the switch determined from the predicted flow. The forwarding engine is operable to forward the packet on the switch fabric to the egress port determined from the predicted flow prior to a lookup module determining a flow from a lookup.

摘要： A system and method of detecting a network cabling change comprises measuring cable parameters of a cable to create a baseline signature of the cable and storing the baseline signature in a memory. The system and method is operable to detect a cable change based upon a comparison of the stored baseline signature and a subsequent cable measurement. A network device operable to perform the above method comprises a physical layer device that transmits signals into a coupled cable and receives return signals from the cable, a cable diagnostic module that measures cable parameters, a memory operable to store a baseline cable signature, and a controlling system that compares subsequently measured cable parameters to the baseline cable signatures to detect a cable change.

摘要： Embodiments of the present disclosure may include methods, systems, and computer readable media with executable instructions. An example method for network virtualization can include providing, by a datacenter (100) having physical and/or virtual resources, a number of virtual tenant datacenters (tDatacenters), each tDatacenter being isolated from other tDatacenters. A tenant virtual local area network (T-VLAN) (226, 228, 682) is associated to each of the number of tDatacenters, and a value of an end-to-end invariant network virtual local area network (VLAN) identification (VID) label (T-VID) is associated to a particular T-VLAN (226, 228, 682). A network packet associated with the particular T-VLAN (226, 228, 682) is modified at an edge network boundary (561) to include the T-VID. The T-VID is configured to have more than 4096 possible values.
