摘要： A new approach is proposed to offload of link aggregation from a host to a HBA in SRIOV mode. The HBA first creates one or more link aggregation offload engines each having one or more physical ports and to establish a first link between a VM running on the host and one of the link aggregation offload engines for network data transmission with the VM. Once a data packet is received from the VM over the first link, the link aggregation offload engine chooses a first physical port based on its link aggregation method and establish a second link with the chosen first physical port to transmit the packet out of the HBA. If the second link fails, the link aggregation offload engine then chooses a second physical ports and establish a third link with the chosen second physical port to transmit the packet out of the HBA device instead.

摘要翻译：提出了一种新的方法来将主机的链路聚合从SRIOV模式卸载到HBA。 HBA首先创建一个或多个链路聚合卸载引擎，每个链路聚合卸载引擎具有一个或多个物理端口，并且在主机上运行的VM和用于与VM进行网络数据传输的链路聚合卸载引擎之间建立第一链路。一旦通过第一链路从VM接收到数据分组，则链路聚合卸载引擎基于其链路聚合方法选择第一物理端口，并与所选择的第一物理端口建立第二链路，以将数据包发送出HBA。如果第二链路失败，则链路聚合卸载引擎然后选择第二物理端口并与所选择的第二物理端口建立第三链路，以将该分组从HBA设备传送出去。

摘要： A new approach is proposed that contemplates systems and methods to support performing a live update or upgrade of a firmware of an embedded networking device to a successful completion without resetting the embedded networking device. For the live update or upgrade to the firmware of the embedded networking device, a new version of the firmware that includes new features/enhancements to improve the product functionality or fix bugs encountered in previous versions of the firmware is installed seamlessly on the embedded networking device to replace the current version of the firmware on one or more cores at a time. During the live firmware updating or upgrading process, various software applications running on other cores of the embedded networking device continue to perform packet processing operations without any interruption. The live firmware update process continues until all cores of the embedded networking device are updated with the newly updated/upgraded firmware.
摘要翻译：提出了一种新方法，其考虑了系统和方法来支持实时更新或升级嵌入式网络设备的固件，以便成功完成，而无需重置嵌入式网络设备。对于实时更新或升级到嵌入式网络设备的固件，包含新功能/增强功能的新版本的固件可以无缝地安装在嵌入式网络设备上，包括改进产品功能或修复以前版本固件遇到的错误一次更换一个或多个内核上的固件的当前版本。在实时固件更新或升级过程中，在嵌入式网络设备的其他核心上运行的各种软件应用程序继续执行数据包处理操作，而不会中断。使用新更新/升级的固件更新嵌入式网络设备的所有核心，直到固件更新过程继续。
