A system includes network interface controller (NIC) and a host processor. The host processor may run a hypervisor or OS which may manage virtual network activity for virtual machines (VMs) and/or applications. The NIC may provide a physical function to the hypervisor to support network activity by the VMs and/or applications. Some VMs and/or applications on the network may bypass the hypervisor and access virtual functions from the NIC. The NIC may execute a configurable flow analyzer (CFA), which may perform flow processing operations on the network traffic. The CFA may access flow configuration and management parameters maintained by the hypervisor to control implementation of the flow processing operations. Performing the flow processing operations on the traffic for the VMs and/or applications bypassing the hypervisor or OS may extend management by the hypervisor or OS to these VMs and/or applications.

Network interface controller with integrated network flow processing

In one embodiment, a method is provided. The method of this embodiment provides storing a packet header at a set of at least one page of memory allocated to storing packet headers, and storing the packet header and a packet payload at a location not in the set of at least one page of memory allocated to storing packet headers.

A management controller in a network device may support performing management operations based on management traffic communicated wirelessly via a wireless network controller of the network devices. The management controller may perform the management operations and/or to support wireless communication of the management traffic independent of operations of the network device. The management controller may be integrated into a network controller in the network device. The management traffic may comprise out-of-band (OOB) management related traffic. A direct interface may be established between the management controller and the wireless network controller, to support direct sideband communication between the management controller and the wireless network controller. The sideband interface may incorporate Network Controller Sideband Interface (NC-SI) and/or Secure Digital Input Output (SDIO) interface. The management controller may control operations of the wireless network controller, by utilizing an embedded wireless controller driver.

Method and system for sideband communication architecture for supporting manageability over wireless LAN (WLAN)

An network controller provides both network controller and management controller functionality. Accordingly, the system host sees, in a single device, both network functionality as well as management functionality. The integration may reduce chip count and provide a more cost effective as well as power efficient platform solution for the network and management functions in a larger system, such as a server with multiple network controllers and multiple network ports.

Network controller with integrated management controller

Various embodiments for hyper-channel management are disclosed. One such method is implemented by a network interface controller (NIC) residing in a server. This method involves determining a network component that is operable to create, modify, terminate, or any combination thereof, a hyper-channel. The hyper-channel corresponds to a logical abstraction of network resources associated with the server. The method also involves using the determined network component to manage the hyper-channel.

Method and system for NIC-centric hyper-channel distributed network management

A local manager in a local networking domain may configure a plurality of logical switches by combining switching functions available in network devices and/or network switches in the local networking domain. The configuration may utilize vertical and/or horizontal combinations of the switching functions. The switching functions may comprise network switch-based switching functions, and/or hypervisor-level switching functions and/or network adapter-level switching functions available in network devices which may be configured as virtualized platforms. The local manager may provide interfacing services to enable exposing configured logical switches. The interfacing services may comprise an internal interface, which may be utilized, via the local manager, to control the switching functions corresponding to logical switches and/or to route messages sent to and/or from the logical switches. The interfacing services may also comprise an external interface, which may be used by external entities, such as remote management entities, to manage and/or interact with configured logical switches.

Header replication in accelerated TCP (Transport Control Protocol) stack processing

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. A pass-through driver may be utilized, in the network controller, to enable transparent routing of management traffic that may be processed externally. The externally processed management traffic may comprise WS-Management based messaging, while management traffic that may comprise ASF based messaging may be processed internally in the network controller. An application processor may be utilized to perform external processing of received and/or transmitted management traffic. A management bus may be utilized to enable routing of management traffic processed external to the network controller. The management bus may also be utilized to enable platform operations during processing of management traffic. The application processor may invoke, via the management bus and/or the pass-through driver, platform based functionality maintained via the network controller.

Method and system for a distributed platform solution for supporting CIM over web services based management

Certain aspects of a method and system for managing network power policy and configuration of data center bridging may include a network domain that comprises a single logical point of management (LPM) that coordinates operation of one or more devices, such as network interface controllers (NICs), switches, and/or servers in the network domain: The single LPM may be operable to manage one or both of a network power policy and/or a data center bridging (DCB) configuration policy for the network domain.

Certain aspects of the present invention provide a method and system for light-weight simple object access protocol (SOAP) transport for web services based management. Aspects of a method may include managing a system using a simple object access protocol (SOAP) message that is mapped over one or both of: a remote management and control protocol (RMCP) and a RMCP security extensions protocol (RSP) to enable remote management of systems using Web services in out-of-band (OOB) management devices.

Distributed Management Task Force (DMTF) management profiles, based on the Common Information Model (CIM) protocol, may be utilized to perform access authentication during opaque management data profile operations based on DMTF/CIM Role Based Authorization (RBA) profile and/or Simple Identity Management (SIM) profiles. Instances of CIM_Identity class may be utilized to enable validation of ownership and/or access rights, via instances of CIM_Role class and/or instances of CIM_Privilege class for a plurality of common users and/or applications. Quota related operations may be performed via 'QuotaAffectsElement' associations between instances of CIM_Identity class and instances of the CIM_OpaqueManagementDataService class. The 'QuotaAffectsElement' association may comprise &#x201c;AllocationQuota&#x201d; and/or &#x201c;AllocatedBytes&#x201d; properties to enable tracking and/or validating of quota related information within the opaque management data profile.
