摘要： A network fabric includes a mobile device associated with a service type and a server including a processor and memory storing program code for assigning identifiers to mobile devices in accordance with an identifier assignment policy. The processor, in response to executing the program code stored in the memory, associates a service type with the mobile device, maps the service type to an identifier predetermined to cause frames bearing the identifier to receive a particular frame-forwarding treatment within the network fabric, assigns the identifier to the mobile device based on the service type of the mobile device, and sends the identifier to the mobile device for inclusion in frames transmitted by the mobile device.

摘要： A switch device includes a packet-forwarding table for providing traffic management across servers in a server group. Each table entry maps a hash value to a server in the server group. A hash value is computed from data in one or more fields in the header of a received packet. The computed hash value is used as an index into the packet-forwarding table to access a table entry and to identify from the table entry the server in the server group to which the table entry maps the computed hash value. The switch device forwards the packet to the identified server. Implementing traffic management decisions in hardware enables packet switching at the line rate of the switch ports. In addition, the hardware-based traffic management performed by the switch device eliminates session tables and the memory to store them, enabling the switch device to handle an unlimited number of client connections.

摘要： A network element in a data center includes a plurality of servers and a switch. The switch includes a plurality of physical ports, a packet-forwarding table, and an application program interface (API) for modifying a packet-forwarding behavior of the switch. The packet-forwarding table determines a packet-traffic distribution across the servers by mapping packet traffic arriving at the switch to the plurality of ports. Each port of the plurality of physical ports is in communication with one of the servers. The network element further includes means for determining in real time the packet-traffic distribution across the servers, and means for dynamically changing the packet-traffic distribution across the servers in response to the determined packet-traffic distribution by modifying the packet-forwarding behavior of the switch through the API of the switch.

摘要： A data center includes a blade server rack with a switch device in communication with a plurality of servers. To process a frame, the switch device determines, from content in a frame header by the switch device, a port through which to forward the frame to a server. The switch device inserts a value into a particular field, for example, a VLAN (virtual Local Area Network) tag, in the frame header before forwarding the frame. The server performs a specific action related to processing the frame based on the value inserted by the switch device into the particular field in the frame header. The server can modify the value in the particular field of the frame header before returning the frame to the switch device, with the switch device performing a specific action based on the value in the particular field of the frame header as modified by the server.
