摘要： A network controller in a communication device may be operable to provide pass-through communication of local host-management traffic between a local host and a management controller within the communication device, wherein the local host may be operable to utilize its network processing resources during communication of the local host-management traffic. The network controller may use packet filtering to provide the pass-through communication, wherein the network controller may utilize a plurality filtering rules during filtering of packets received in the network controller. The filtering rules may specify packet processing and/or forwarding actions by said network controller based on one or more specified conditions. The specified conditions may based on one or more match criteria; wherein the match criteria comprising source address, destination address, and/or traffic type data in the received packets. Address learning mechanisms may be used in the network controller to enable configuring and/or performing packet filtering transparently.

An Internet protocol address table index may be looked up in the Internet protocol address table for a first lookup of the multi-level lookup process. A security protocol index may be looked up utilizing the Internet protocol address table index for a second lookup of the multi-level lookup process. The Internet protocol security parameters may be determined utilizing the security protocol index. IPsec processing may be performed utilizing the determined Internet protocol security parameters.

摘要： A portion of management traffic, carried via network traffic, and received and/or transmitted via a network controller, may be processed externally to the network controller, wherein management messaging may be carried via network packets, and one or more headers may added to enable transmission and/or reception via the network controller. Packet filters may be setup, in the network controller, via the management controller, to enable determining network packets that may carry the management traffic. The management controller may utilize commands to setup packet filers in the network controller, wherein matching criteria, in received network packets, and/or corresponding actions that may be performed in matching packets, may be specified. The matching criteria may comprise specifying one or more header types that may be utilized in the received network packets. The network controller may generate filter identifiers, which may be utilized, subsequently, via the management controller to delete the packet filters.

摘要： Methods and systems for virtualization and re-direction of I/O connections to peripheral devices are disclosed. Aspects of one method may include virtualizing one or more peripheral devices via corresponding PCI/PCIe level functions. The virtualization may comprise, for example, emulating peripheral device controllers. The PCI and/or PCIe level functions may then redirect accesses to peripheral devices to corresponding virtual devices. Since a PCI/PCIe level function may emulate a peripheral device controller, the redirecting may occur without modifying an operating system for the electronic system or the corresponding device driver used to access the peripheral device. Accordingly, virtualization and redirection may enable controlling a remote electronic system over a network. The controlling of a remote electronic system may comprise, for example, storing and accessing data in a remote storage device, booting from the remote storage device, and scanning and/or printing at the remote device.

摘要： Embodiments for providing access to computing system resources, such as files, disks, flash storage and/or other resources, are disclosed. A combination network interface and storage device can be installed in a computing system, which can be configured to draw power when a host computing system is in a sleep state. A subsystem executed by the combination network interface and storage device can allow a client device to submit a request for a file stored in a storage medium accessible to the device. Additionally, the subsystem can facilitate mirroring of files from mass storage devices by the operating system and/or applications executed by the host computing system when the computing system is not in a sleep state.
