摘要： User space applications can utilize custom network protocol timers. A registration request is received from an application to register a custom timer. Responsive to receiving the registration request, a handle is created. The handle is a pointer to be used by the application to reference the custom timer. The handle is forwarded to the application. When a custom timer is required, a request to use a custom timer is received from an application. The kernel is then requested to start the custom timer. A determination is then made as to whether a receipt confirmation is received from the kernel before expiration of the custom timer.

摘要： A method identifies a network socket on a machine by assigning a non-IP address socket anchor and a port number to the network socket. A socket anchor may comprise a globally unique number. In some embodiments, a socket anchor comprises a number having a preselected number of bits. The number having the preselected number of bits may comprise a selected number associated with the machine concatenated with a number of randomly generated bits. The number of bits of the selected number plus the number of randomly generated bits is equal to the preselected number of bits. In some embodiments, the selected number associated with the machine is a Media Access Control (MAC) address of a network interface associated with the machine.

摘要： A kernel extension is configured to intercept a call to associate a socket with a port of a node in a network. The call originates from a kernel of the node. The kernel extension is configured to determine the port from the call. The kernel extension is configured to determine that the port is one of a plurality of ports for which the node has authority to modify firewall rules of a firewall of the network. The kernel extension is configured to modify firewall rules maintained by the firewall to allow communications for the port to the node through the firewall.

摘要： A service module that provides for discovery of one or more network interfaces connecting a prospective remote procedure call (RPC) client, facilitates the provision of RPC programs in a network including multi-horned systems. When a request for a network address to an RPC application providing an RPC program is received from the RPC client, the RPC bind daemon discovers from the module, using the client response address, over which interface(s) the client is accessible. The daemon then selects an address of a network path to the RPC application that the prospective client can access and returns the corresponding network address. The service module monitors the network stack for RPC get address requests and builds tables of client address entries with corresponding network interface identifiers. The entries are retired according to an aging policy.

摘要： In a method for managing shared Ethernet adapters in a virtualized computer environment, a computer programmed with a hypervisor program receives a first request from a virtual client to transmit data. In response to receiving the first request, the computer programmed with the hypervisor program selects a first active virtual server from a first plurality of concurrently active virtual servers of the virtualized computer environment. The computer programmed with the hypervisor program copies the data from a memory of the virtual client to a trunk adapter of a first shared Ethernet adapter of the selected first active virtual server.

摘要： The present invention provides a computer implemented method for resolving a universal resource identifier (URI). The client computer receives the universal resource identifier, which is comprised of a domain name. The client computer looks up a row corresponding to the domain name in a domain specific domain name service (DNS) server list. The row includes at least a first internet protocol address. The client computer transmits a domain name service (DNS) query addressed to the first internet protocol address responsive to looking up the row. Upon receiving a valid response in at least one packet, wherein the at least one packet is from the first internet protocol address, the client computer resolves the universal resource identifier to a second internet protocol address.

摘要： A method, system, and computer program product for a self-adjusting application heartbeat management process are provided in the illustrative embodiments. A first application receives from a second application, a response message in response to a heartbeat message. Information is identified in the response message usable for computing a delay in a future response message for a future heartbeat message, such that the information communicates to the first application a system condition existing in the second data processing system where the second application is executing. A response time is adjusted using the information to form a modified response time. The future response message is received after the response time.

摘要： In a computer system having memory, at least one processor and a physical input-output adapter, the at least one processor generates logical partitions, including local logical partitions and an input-output logical partition. The logical partitions have respective local virtual adapters. The input-output logical partition has a shared virtual adapter configured to communicate with the physical input-output adapter, such that a plurality of the local logical partitions share the physical input-output adapter via the shared virtual adapter. The at least one processor provides communication for ones of the local virtual adapters of the local logical partitions directly with the physical input-output adapter by a hypervisor.
