Abstract: A processor node of a network is provided which includes one or more processors and a virtualized channel adapter. The virtualized channel adapter is operable to reference a table to determine whether a destination of the communication is supported by the virtualized channel adapter. When the destination is supported for routing via hardware, the virtualized channel adapter is operable to route the communication via hardware to at least one of a physical port and a logical port of the virtualized channel adapter. Otherwise, when the destination is not supported for routing via hardware, the virtualized channel adapter is operable to route the communication via firmware to a virtual port of the virtualized channel adapter. A corresponding method and a recording medium having information recorded thereon for performing such method are also provided herein.

Abstract: A method, system, and computer program product are disclosed within a logically partitioned data processing system for providing an aliased queue pair for each logical partition for the single general services management queue pair that exists within a physical host channel adapter. Packets intended for the logical ports are received at the physical port. Multiple partitions exist within the data processing system. When one of these partitions needs to use one of the logical ports, a queue pair is selected. The queue pair is then associated with the logical port. The queue pair is configured as an aliased general services management queue pair and is used by the partition as if the aliased queue pair were the single general services management queue pair provided in the channel adapter.

Abstract: Systems and methods directed at enhancing the capability of a federated authentication system by configuring the system with extensibility points for adding new account stores and customizing claim transformations. The federated authentication system includes accounts stores, a security token service (STS), and custom claim transformation modules. The account stores are configured to maintain data associated with accounts and to provide security claims in an intermediate format. The STS is configured to retrieve the security claims provided by the account stores and includes built-in transformations for transforming each security claim from the intermediate format to formats associated with resource providers. The STS is further configured to provide extensibility points for custom claim transformations that are not available from the built-in transformations. The custom claim transformation modules are configured to perform at least one custom claim transformation. Each custom claim transformation module is further configured to interact with the STS through at least one of the extensibility points. The STS may be configured to provide extensibility points for interacting with account stores that the STS does not explicitly recognize.

Abstract: Systems and methods directed at transforming security claims in a federated authentication system using an intermediate format. The systems and methods described herein are directed at transforming security claims in a federated authentication system using an intermediate format. The federated authentication system includes an identity provider and a resource provider. The identity provider receives a request for information from the resource provider to authenticate an account by an application associated with the resource provider. A security claim associated with the account is retrieved where the security claim is provided by an account store in a format specific to the account store. The security claim is transformed from the account store specific format to an intermediate format. The security claim is then transformed from the intermediate format to a federated format recognized by the resource provider. The transformed security claim is provided in a security token to the resource provider. A similar two step transformation process using intermediate claims can also be implemented by the resource provider to transform security claims provided by an identity provider from a federated format to formats recognized by the applications.

Abstract: A Host Channel Adapter supporting a plurality of Logical Partitions is provided. A Subnet Manager, having an associated aliased Queue Pair, may run in a Logical Partition. A single physical subnet management Queue Pair and its associated firmware are provided for each physical port in the Host Channel Adapter. If a packet is to be routed to a Subnet Manager residing in a Logical Partition, the packet is enqueued on the physical port's send queue for transmission to the aliased Queue Pair for the Subnet Manager. The Host Channel Adapter hardware loops the packet back to the aliased Queue Pair in the appropriate Logical Partition. The aliased Queue Pair is also capable of transmitting packets that are looped back to a Hypervisor Subnet Management Agent.

Abstract: I/O adapters, such as InfiniBand™ host channel adapters (HCAs) or iWarp remote network interface cards (RNICs) use work requests to pass information to a queue pair and work completions to determine when a work request has completed. Timing information in various stages of processing of these work requests allow a workload manager to identify sources of delay that impacts transaction processing. Work requests request processing that can be marked with a timestamp. Processing stages include: (1) the time when the work request is posted to the send queue, (2) the time when the first packet is sent on the link for that work request, (3) the time at which the work request has completed its processing, and (4) the time when the work completion is retrieved by the software. By comparing the timestamps, the workload manager determines the processing and transaction times.

Abstract translation: 诸如InfiniBand（TM）主机通道适配器（HCAs）或iWarp远程网络接口卡（RNIC）之类的I / O适配器使用工作请求将信息传递到队列对并进行完成以确定工作请求何时完成。 处理这些工作请求的各个阶段的定时信息允许工作负载管理器识别影响事务处理的延迟源。 工作请求请求处理可以用时间戳标记。 处理阶段包括：（1）工作请求发布到发送队列的时间，（2）第一个数据包在该工作请求的链接上发送的时间，（3）工作请求的时间 完成其处理，（4）软件检索工作完成的时间。 通过比较时间戳，工作负载管理器确定处理和事务时间。
