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.

Abstract: A management device may determine the presence of WS-Management services in a network device, and may discover capabilities of discovered WS-Management services in the network device. The management device may determine the presence of the WS-Management services utilizing a unicast ping mechanism in instances where the MAC and/or IP address of the network device may be known or a broadcast ping mechanism may be utilized in instances when the MAC and/or IP address is unknown. The discovery of capabilities of the WS-Management services may be performed via direct communication between the devices, and may utilize WS-Management based messaging. The direct communication may utilize specific HTTP ports when utilizing WS-Management based messaging. Where WS-Management and ASF services may coexist in the network device, the management device may additionally perform discovery of capabilities of ASF services, and may utilize ASF based messaging to perform discovery of capabilities of discovered ASF services.

Abstract: Provided are a method, system, and program for managing memory options for a device such as an I/O device. Private addresses provided by logic blocks within the device may be transparently routed to either an optional external memory or to system memory, depending upon which of the optional memories the private address has been mapped.

Abstract: Provided are a method, system, and program for utilizing a virtualized data structure table such as an address translation and protection table (TPT), for example, in an I/O device. The virtualized data structure table has virtually contiguous data structures but not necessarily physically contiguous data structures in system memory. The data structure table may be accessed in a virtually contiguous manner. In the illustrated embodiment, the table is subdivided at a first hierarchal level into a plurality of virtually contiguous units or segments. Each unit or segment is in turn subdivided at a second hierarchal level into a plurality of virtually contiguous subunits, subsegments, pages or blocks. Each page or block is in turn subdivided at a third hierarchal level into a plurality of physically contiguous table entries.

Abstract: Provided are a method, system, and program for caching a virtualized data structure table. In one embodiment, an input/output (I/O) device has a cache subsystem for a data structure table which has been virtualized. As a consequence, the data structure table cache may be addressed using a virtual address or index. For example, a network adapter may maintain an address translation and protection table (TPT) which has virtually contiguous data structures but not necessarily physically contiguous data structures in system memory. TPT entries may be stored in a cache and addressed using a virtual address or index. Mapping tables may be stored in the cache as well and addressed using a virtual address or index.

Abstract: A card receives data encoded in a protocol. The data may be divided into packets, or still in a protocol data unit. If still in a protocol data unit, the card divides the data into packets of appropriate size. Digests appropriate to the protocol are computed and inserted into the packets. Checksums are generated for the packets that need them, such as the packet now including the digest. The packets may then be transmitted to a recipient.

Abstract: A network offload engine having a first buffer to store packet payloads that are received at the network offload engine until being copied to a location in a receive buffer of a host memory. An engine is programmed to copy contents of the first buffer to the location in the receive buffer of the host memory in response to meeting a first precondition. Host notification of the copy is postponed until a second precondition is met. Other embodiments are also described.

Abstract: Provided are techniques for interrupt processing. An Input/Output device determines that an event has occurred. The Input/Output device determines a state of an event data structure. The Input/Output device writes an event entry into the event data structure in response to determining that the event has occurred. After writing the event entry, the Input/Output device determines whether to generate an interrupt or not based on the state of the event data structure. Additionally provided are techniques for interrupt processing in which an I/O device driver determines that an interrupt has occurred. The I/O device driver reads an event entry in an event data structure in response to determining that the interrupt has occurred. The I/O device driver updates a state of a structure state indicator to enable/disable interrupts.

Abstract: Provided are techniques for interrupt processing. An Input/Output device determines that an event has occurred. The Input/Output device determines a processor identifier and determines an event data structure identifier for an event data structure into which data for the event is stored using the processor identifier. The Input/Output device also determines a vector identifier for an interrupt message vector into which an interrupt message for the event is written. Then, interrupt message data is written to the interrupt message vector to generate an interrupt.

Abstract: A method and system for transmitting packets. Packets may be transmitted when a protocol control block is copied from a host processing system to a network protocol offload engine. Message information that contains packet payload addresses may be provided to the network protocol offload engine to generate a plurality of message contexts in the offload engine. With the message contexts, protocol processing may be performed at the offload engine while leaving the packet payload in the host memory. Thus, packet payloads may be transmitted directly from the host memory to a network communication link during transmission of the packets by the offload engine. Other embodiments are also described.

Abstract: This invention applies the concept of time-sharing to help fill the needs of industry for a pool of highly skilled individuals at a more affordable rate then if they were required to maintain a sufficient skilled workforce for projects that evolve out of a highly dynamic environment. Simply stated individuals with the skill sets needed by business and industry would contract with the provider and be placed in the Time Share Skills (TSS) database system. Business and Industry would buy or place an order from the Time Share Skills (TSS) provider the projected needed skills for a time in the future at a rate that would be significantly less then if they had to hire and develop the projected work force for projects.
