网络卸载和优化技术Network offload and optimization technologies

在本主题中,我们概括介绍了 Windows Server 2016 中提供的不同网络卸载和优化功能,并讨论了它们如何帮助使网络更高效。In this topic, we give you an overview of the different network offload and optimization features available in Windows Server 2016 and discuss how they help make networking more efficient. 这些技术仅包括软件 (因此) 功能和技术、软件和硬件 (SH) 集成的功能和技术,以及仅 (的功能和技术。These technologies include Software Only (SO) features and technologies, Software and Hardware (SH) integrated features and technologies, and Hardware Only (HO) features and technologies.

Windows Server 2016 中提供的三个网络功能类别为:The three categories of networking features available in Windows Server 2016 are:

  1. 软件仅 (因此) 功能和技术:这些功能作为 OS 的一部分实现,并且独立于基础 NIC () 。Software only (SO) features and technologies: These features are implemented as part of the OS and are independent of the underlying NIC(s). 有时,这些功能需要对 NIC 进行某种优化才能实现最佳操作。Sometimes these features will require some tuning of the NIC for optimal operation. 其中的示例包括 Hyper-v 功能,如 vmQoS、Acl 和非 Hyper-v 功能,如 NIC 组合。Examples of these include Hyper-v features such as vmQoS, ACLs, and non-Hyper-V features like NIC Teaming.

  2. 软件和硬件 (SH) 集成功能和技术:这些功能都具有软件和硬件组件。Software and Hardware (SH) integrated features and technologies: These features have both software and hardware components. 该软件与它紧密功能所需的硬件功能相结合。The software is intimately tied to hardware capabilities that are required for the feature to work. 其中包括 VMMQ、VMQ、发送端 IPv4 校验和卸载以及 RSS。Examples of these include VMMQ, VMQ, Send-side IPv4 Checksum Offload, and RSS.

  3. 仅限硬件 (哈) 功能和技术:这些硬件加速可提高网络性能和软件,但不它紧密任何软件功能。Hardware Only (HO) features and technologies: These hardware accelerations improve networking performance in conjunction with the software but are not intimately part of any software feature. 这些示例包括中断裁决、流控制和接收端 IPv4 校验和卸载。Examples of these include Interrupt Moderation, Flow Control, and Receive-side IPv4 Checksum Offload.

  4. NIC 高级属性:可以使用 get-netadapter Cmdlet 通过 Windows PowerShell 管理 nic 和所有功能。NIC advanced properties: You can manage NICs and all the features via Windows PowerShell using the NetAdapter cmdlet. 你还可以使用网络控制面板 ( # A0) 来管理 Nic 和所有功能。You can also manage NICs and all the features using Network Control Panel (ncpa.cpl).

提示

  • 因此,无论 NIC 速度或 NIC 功能如何,所有硬件体系结构中都提供了功能和技术。SO features and technologies are available in all hardware architectures, regardless of NIC speed or NIC capabilities.

  • 如果你的网络适配器支持这些功能或技术,则 SH 和 HO 功能才可用。SH and HO features are available only when your network adapter supports the features or technologies.
