摘要： The increasing number of Internet users and innovative new services such as e-commerce are placing new demands on Web servers. It is becoming essential for Web servers to provide performance isolation, have fast recovery times, and provide continuous service during overload at least to preferred customers. The invention describes a kernel-based architecture for content-aware service differentiation that protects Web servers against overload by controlling the amount and rate of work entering the system. We have invented a mechanism that provides admission control and service differentiation based on connection and application level information. The application header-based connection control uses application-level information (such as URIs and cookies for HTTP) to define different service differentiation actions. The present invention provides the kernel mechanisms that are more efficient and scalable than application level controls implemented in current Web servers.

摘要： Network resources are provisioned within an application broker according to aggregated requests in an optical network. Resource requests are sorted to form sorted resource requests. The sorted resource requests are sorted according to destinations of the resource requests. The sorted resource requests are aggregated to form aggregated resource requests. Resource allocation is requested for each of the aggregated resource requests from a network border controller based on requirements of the set of set of aggregated resource requests. A set of allocated resources is received from the network border controller. The set of allocated resources is based on requirements of the aggregated resource requests. For each of the aggregated resource requests, network transmissions network receptions are executed utilizing associated allocated resources.

摘要： Mechanisms to address the situation where an input/output (I/O) fabric is shared by more than one logical partition (LPAR) and where each LPAR can share with the other LPARs an I/O adapter (LOA) are provided. In particular, each LPAR is assigned its own separate address space to access a virtual function (VF) assigned to it such that each LPAR's perception is that it has its own independent IOA. Each VF may be shared across multiple LPARs. Facilities are provided for management of the shared resources of the IOA via a Physical Function (PF) of the IOA by assignment of that PF to an I/O Virtualization Management Partition (IMP). The code running in the IMP acts as a virtual intermediary to the VFs for fully managing the VF error handling, VF reset, and configuration operations. The IMP also acts as an interface to the PF for accessing common VF functionality. Furthermore, the functions of resource assignment and management relative to the VFs and the client partitions that use those VFs, which might normally be done by an entity like a hypervisor, are implemented by this IMP.

摘要： Mechanisms for communication between host systems using a socket connection and shared memories are provided. With such socket-based communication, a work queue in the host systems may be used to listen for incoming socket initialization requests. A first host system that wishes to establish a socket communication connection with a second host system may generate a socket initialization request work queue element in its work queue and may inform the second host system that the socket initialization request work queue element is available for processing. The second host system may then accept or deny the request. If the second host system accepts the request, it returns the second half of the socket's parameters for use by the first host system in performing socket based communications between the first and second host systems.

摘要： Mechanisms for migration of single root stateless virtual functions are provided. A Single-Root PCI Configuration Manager (SR-PCIM) provides a system image (SI) with possible virtual function (VF) migration scenarios supported by the endpoint (EP). The SR-PCIM may be instructed that a stateless migration of a VF and its associated application(s) from one SI to another is required. Outstanding requests to the VF are completed and any applications associated with the VF are removed from the SI and the VF is detached from its associated physical function (PF). The SWI may then attach the VF to a target PF which may be in the same or a different EP. The SWI makes the VF available to the SI with which the VF is now associated and the SI configures the VF thereby making it available for use by associated applications.

摘要： Mechanisms for hot-plug/remove of a new component in a running communication fabric, such as a PCIe fabric, are provided. With these mechanisms, the addition of a new component in the fabric is detected and an event is sent to a multiple root fabric configuration manager. The multiple root fabric configuration manager gathers information about the new component and updates its I/O component tree structure in its configuration data structure to include the new component. The new component may then be utilized via the updated configuration data structure. When a component is to be removed, the multiple root fabric configuration manager receives an event indicating the component to be removed, determines which branches of the tree structure are affected by the removal, and updates its configuration data structure accordingly to remove the component and its associated components from the virtual plane of the removed component.

摘要： In one embodiment, a computer-implemented method for creating redundant system configurations is presented. The computer-implemented method creates a set of virtual function path authorization tables, and receives a request from a requester to provide requested data from a virtual function wherein the virtual function is performed by a single root or a multi-root peripheral component interconnect device. Further a receive buffer is created in a selected address range in a set of addresses ranges as well as a virtual function work queue entry for the virtual function containing an address of the receive buffer in the selected address range. Responsive to a determination that the virtual function is authorized, writing the requested data into the receive buffer of the selected address range in the one or more systems, and responsive to writing the requested data, issuing a notice of completion to the requester.
