摘要： In general, techniques are described for facilitating multi-tenancy of a server accessed by virtual networks of a data center. A device included within a data center comprising one or more processors may perform the techniques. The processors may be configured to execute a virtual switch that supports a number of virtual networks executing within the data center. The virtual switch may be configured to receive a request regarding data associated with an identifier that is unique within one of the virtual networks that originated the request. The virtual switch may then translate the identifier included within the request to generate a globally unique identifier that is unique within the plurality of virtual networks, update the request to replace the identifier included within the request with the globally unique identifier, and transmit the updated request to a server of the data center.

摘要： A method for enabling autonegotiation over an interface for which no autonegotiation standard exists comprises establishing network communication between a first network device and a second network device over a communication link. The first network device includes a first media access controller (MAC) associated with a communication port coupled to the communication link and a second MAC positioned between the first MAC and the communication port, and the second MAC operates as a proxy MAC for the first MAC. The first MAC outputs an outbound data communication to the communication port at a first communication rate. The proxy MAC intercepts the outbound data communication. The proxy MAC then outputs the outbound data communication to the communication port at a second communication rate different from the first communication rate.

摘要： In general, techniques are described in which a plurality of network switches automatically configure themselves to operate as a single virtual network switch. A virtual switch is a collection of individual switch devices that operate like as single network switch. As described herein, network switches in a network that are capable of participating in a virtual switch may automatically discover one another. The participating network switches may then elect one of the participating switches as a master switch. The master switch may generate forwarding information and store the forwarding information in the participating switches, including the master switch. The forwarding information causes the participating switches to act like a single network switch.

摘要： In one example, a network device includes a virtual network agent, and a network interface to send network packets to the virtual network controller using a default route for a physical network prior to establishing a communication session between a virtual network controller and the virtual network agent, wherein, after establishing the communication session between the virtual network controller device and the virtual network agent, the virtual network agent receives from the virtual network controller a command to install a new route at the network device, wherein the new route specifies encapsulation information to use for encapsulating network packets for sending the network packets to the virtual network controller over an overlay network, and wherein, responsive to detecting a failed link in the physical network, the virtual network agent sends packets to the virtual network controller on an alternate route in the overlay network.

摘要： A method is provided to reduce multicast traffic by snooping IGMP control packets on a packet-forwarding device. A multicast traffic reducer includes an IGMP proxy, which operates in conjunction with an IGMP snooper to intercept selected IGMP control packets and generate proxy IGMP control packets in their place. The IGMP proxy may include an IGMP query batcher to consolidate IGMP queries to multicast host groups, an IGMP query responder to consolidate host responses to the IGMP queries to multicast host groups, and/or an IGMP leave forwarder to manage host IGMP leave packets. The IGMP proxy consolidates or discards host-generated IGMP control packets and timely generates IGMP proxy control packets in their place. The IGMP proxy further includes an IGMP layer-2 query generator to initiate IGMP queries for a layer-2 router multicast application.
