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： 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： 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： 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.
