摘要： Techniques are provided for improve quality of service on uplinks in a virtualized environment. At a server apparatus having a plurality of physical links configured to communicate traffic over a network to or from the server apparatus, forming an uplink group comprising a plurality of physical links. A first class of service is defined that allocates a first share of available bandwidth on the uplink group, and a second class of service is defined that allocates a second share of available bandwidth on the uplink group. The bandwidth for the first class of service is allocated across the plurality of physical links of the uplink group, and the bandwidth for the second class of service is allocated across the plurality of physical links of the uplink group. Traffic rates are monitored on each of the plurality of physical links to determine if a physical link is congested indicating that a bandwidth deficit exists for a class of service. In response to determining that one of the plurality of physical links is congested, bandwidth is reallocated for a class of service to reduce the bandwidth deficit for a corresponding class of service.

摘要： Disclosed are, inter alia, methods, apparatus, computer-storage media, mechanisms, and means associated with loss of reducing flooding in a bridged network, typically including a device directly connected to multiple upstream bridges. These bridges are configured such that the device receives broadcast/multicast traffic from a single interface of one of the bridges, while allowing unicast traffic over each of the communications links connecting the device to the bridges. In one configuration, the device implements virtual machine(s), each including a virtual network interface associated with a MAC address; and the directly connected bridges are configured, for each particular MAC address of these MAC addresses of the virtual interfaces, such that one and only one of the bridges will forward packets having the particular MAC address as its destination address over a communications link directly connected to the device.

摘要： A storage router having an internet protocol (IP) port for coupling to a network supporting IP packets, a fibre channel port for coupling to a fibre channel network to a plurality of storage devices, and a SCSI router having an iSCSI interface that extracts SCSI command and data information from packets received through the IP port, wherein the SCSI router passes the extracted SCSI command and data information to the fiber channel port. Some embodiments further include a session to an information-handling system. The session supports a target-only mapping (wherein a source-specified target value is replaced by a mapped target value that is then passed by the SCSI router toward a first storage device and its LUNs), or target-and-LUN mapping (wherein source-specified target and LUN information is replaced by mapped target-and LUN information such as a loop-ID and LUN combination, a WWPN and LUN combination, or a WWNN).

摘要： A method for creating a virtual MAC address, the method includes receiving an Internet Protocol address that is to be associated with a virtual MAC address. The method creates a virtual MAC address by setting an OUI portion of the virtual MAC address to an OUI value and setting the non-OUI portion of the virtual MAC address to a subset of the Internet Protocol (IP) address. In one embodiment, the lower three bytes of the IP address are used. Additionally, a method of migrating a virtual MAC address includes detecting a migration event on a first system; creating a virtual MAC address on a second system; and issuing a gratuitous ARP packet containing the virtual MAC address.

摘要： A method and system to exchange information between computer applications are provided. The system may include a source operating system, a destination operating system and an offload stack, all residing on the device. The source operating system and the destination operating system appear to users as distinct network entities. The offload stack may be configured to function as an intermediate network device for the source operating system. The offload stack, in one embodiment, comprises a back end to receive a message from the source operating system to the destination operating system, an analyzer to determine that the destination operating system resides on the device and a cut though socket module to process the message such that a network layer of the offload stack is bypassed.
