摘要： The present invention defines a new protocol for communicating with an offload engine that provides Transmission Control Protocol ("TCP") termination over a Fibre Channel ("FC") fabric. The offload engine terminates all protocols up to and including TCP and performs the processing associated with those layers. The offload protocol guarantees delivery and is encapsulated within FCP-formatted frames. Thus, the TCP streams are reliably passed to the host. Additionally, using this scheme, the offload engine can provide parsing of the TCP stream to further assist the host. The present invention also provides network devices (and components thereof) that are configured to perform the foregoing methods. The invention further defines how network attached storage ("NAS") protocol data units ("PDUs") are parsed and delivered.

摘要： A computer system, comprising at least one controlled execution space hosting an operating system and an application program; a vulnerability monitoring agent coupled to the controlled execution space; one or more vulnerability profiles coupled to the vulnerability monitoring agent, wherein each of the vulnerability profiles comprises an application program identifier, an operating system identifier, a vulnerability specification describing a vulnerability of an application program that the application program identifier indicates when executed with an operating system that the operating system identifier indicates, and a remedial action which when executed will remediate the vulnerability; wherein the vulnerability monitoring agent is configured to monitor execution of the operating system and the application program in the controlled execution space, to detect an anomaly associated with the vulnerability, to determine the remedial action for the operating system and application program based on one of the vulnerability profiles, and to cause the remedial action.

摘要： An apparatus for offloading network, block and file functions from an operating system comprises a network interface (118A,118B) coupled to a network for receiving packet flows; one or more processors each having one or more processor cores; a computer- readable medium carrying one or more operating systems and an input/output networking stack (110) which are hosted in one or more of the processor cores. The networking stack is shared among the operating systems (104A,104B). The networking stack comprises instructions which when executed cause receiving a request for data transfer from one of the operating systems at internal network, block and file system interfaces (112,114,116), and permitting data to be transferred between the internal interfaces and a plurality of external interfaces (118A-118D) by preventing the operating systems from performing the data transfer and performing the data transfer on behalf of the operating systems.
摘要翻译：用于从操作系统卸载网络，块和文件功能的设备包括：网络接口（118A，118B），其耦合到网络以用于接收分组流; 一个或多个处理器，每个处理器具有一个或多个处理器核; 携带一个或多个操作系统的计算机可读介质以及托管在一个或多个处理器内核中的输入/输出网络栈（110）。网络栈在操作系统（104A，104B）之间共享。联网堆栈包括指令，所述指令在被执行时导致从内部网络，块和文件系统接口（112,114,116）处的操作系统中的一个接收数据传输的请求，并且允许数据在内部接口和多个外部接口（118A-118D），防止操作系统执行数据传输并代表操作系统执行数据传输。

摘要： In one embodiment a method includes selectively controlling a virtual network switch to control a quality of service (QoS) for a flow associated with a virtual machine (VM). Controlling the QoS may include controlling the virtual switch to provide classification, congestion management, congestion avoidance, bandwidth limiting, traffic shaping, and/or priority manipulation. The method may also include migrating a policy associated with a virtuai interface between the VM and the virtual switch from a first server to a second server when the VM is to be migrated from the first server to the second server. The migration may also include moving statistics associated with the policy. The method may include selectively adapting the policy or an existing policy on the receiving server when a discrepancy is detected between the policies. The method may include reserving resources to provide guaranteed minimum bandwidth, even without control of an ingress and egress queue.
摘要翻译：在一个实施例中，一种方法包括选择性地控制虚拟网络交换机以控制与虚拟机（VM）相关联的流的服务质量（QoS）。控制QoS可以包括控制虚拟交换机提供分类，拥塞管理，拥塞避免，带宽限制，流量整形和/或优先级操纵。该方法还可以包括当VM要从第一服务器迁移到第二服务器时，将与虚拟交换机之间的虚拟交换机的虚拟接口相关联的策略从第一服务器迁移到第二服务器。迁移还可能包括移动与策略关联的统计信息。当在策略之间检测到差异时，该方法可以包括选择性地调整策略或接收服务器上的现有策略。该方法可以包括预留资源以提供保证的最小带宽，即使不控制入口和出口队列。

摘要： The subject technology addresses the need in the art for improving provisioning and booting of virtual machines in a cloud computing environment. Different versions of boot volume images may be shared in a storage repository accessible by one or more host computers. When a virtual machine is created, a shared boot volume image, including confirmation information for the virtual machine, may be selected for booting the virtual machine. Over time, newer version(s) of boot volume images may be stored in the storage repository and new virtual machine(s) may use the newer version of the boot volume image for booting.
