    摘要: A technique is provided for implementing online mirroring of a volume in a storage area network. A first instance of the volume is instantiated at a first port of the fibre channel fabric for enabling I/O operations to be performed at the volume. One or more mirroring procedures may be performed at the volume. In at least one implementation, the first port is able to perform first I/O operations at the volume concurrently while the mirroring procedures are being performed at the first volume. In one implementation, the mirroring procedures may be implemented at a fabric switch of the storage area network. Additionally, in at least one implementation, multiple hosts may be provided with concurrent access to the volume during the mirroring operations without serializing the access to the volume.

    摘要: Methods and apparatus for authenticating a mobile node are disclosed. A server is configured to provide a plurality of security associations associated with a plurality of mobile nodes. A packet identifying a mobile node may then be sent to the server from a network device such as a Home Agent. A security association for the mobile node identified in the packet may then be obtained from the server. The security association may be sent to the network device to permit authentication of the mobile node. Alternatively, authentication of the mobile node may be performed at the server by applying the security association.

    摘要: A Data Center Ethernet (“DCE”) network and related methods and device are provided. A DCE network simplifies the connectivity of data centers and provides a high bandwidth, low latency network for carrying Ethernet, storage and other traffic. A Fibre Channel (“FC”) frame, including FC addressing information, is encapsulated in an Ethernet frame for transmission on a Data Center Ethernet (“DCE”) network. The Ethernet address fields may indicate that the frame includes an FC frame, e.g., by the use of a predetermined Organization Unique Identifier (“OUI”) code in the D_MAC field, but also include Ethernet addressing information. Accordingly, the encapsulated frames can be forwarded properly by switches in the DCE network whether or not these switches are configured for operation according to the FC protocol. Accordingly, only a subset of Ethernet switches in the DCE network needs to be FC-enabled. Only switches so configured will require an FC Domain_ID.

    摘要: Methods and devices are provided for automating a login process and user/device associations. A user's preferred device settings and/or functions may be provisioned automatically. Some implementations provide an automated log out or “sleep” when a user leaves one or more of the devices. Users may be automatically identified and associated. The “presence” of members of a user group may be determined as required for one or more actions to be taken. Some user groups control devices according to which members of a group may have access to certain functions, information, etc., and which may not.

    摘要: The present invention provides methods and devices for implementing a Low Latency Ethernet (“LLE”) solution, also referred to herein as a Data Center Ethernet (“DCE”) solution, which simplifies the connectivity of data centers and provides a high bandwidth, low latency network for carrying Ethernet and storage traffic. Some aspects of the invention involve transforming FC frames into a format suitable for transport on an Ethernet. Some preferred implementations of the invention implement multiple virtual lanes (“VLs”) in a single physical connection of a data center or similar network. Some VLs are “drop” VLs, with Ethernet-like behavior, and others are “no-drop” lanes with FC-like behavior. Some preferred implementations of the invention provide guaranteed bandwidth based on credits and VL. Active buffer management allows for both high reliability and low latency while using small frame buffers. Preferably, the rules for active buffer management are different for drop and no drop VLs.

    摘要: Methods and devices are provided for determining the status of a networked device, e.g., a networked RFID device. In some embodiments of the invention, a customized packet is used to transmit a “heartbeat” from each of a plurality of networked devices to a server. Some such embodiments use a customized syslog packet for the heartbeats. The heartbeat includes identification information regarding the device, e.g., the unique electronic product code (“EPC”) of the device. The identification information may include other identification and/or authentication information, such as a shared secret and time data, which may be hashed with the identification information. The heartbeat may include information indicating the health, accuracy and/or reliability of the device and/or of the network that includes the device.

    摘要: Methods and devices are provided for locating, identifying and provisioning devices in a network. According to some implementations of the invention, a combination of EPC code information and existing networking standards form the basis of identifying and provisioning methods. For example, location information included in a DHCPDISCOVER request can be used to determine appropriate configurations for networked devices. In some such implementations, the location information is read from an RFID tag near the networked device and is inserted in the DHCPDISCOVER request. The location information may include any type of absolute or relative coordinate, positioning, cartographic or similar information and/or information from which such information may be derived.
