摘要： A network communication device can implement configurable network socket retransmission timeout parameters on a per socket basis. In one embodiment, it is determined, at a first network device, whether to define a network socket with a custom or a default retransmission timeout value to transmit data to a second network device. In response to determining to define the network socket with the custom retransmission timeout value, the network socket is defined with the custom retransmission timeout value, the data is transmitted to the second network device, and it is determined whether response data is received from the second network device prior to expiration of a time period associated with the custom retransmission timeout value. In response to determining that the response data is not received from the second network device prior to the expiration of the corresponding time period, the data is retransmitted to the second network device.

摘要： A network device can implement configurable socket aggregation to enable segmentation offload in the network device. In one embodiment, it is determined, at the network device, to create a network socket for an application of the network device to initiate a network connection for the application. Socket aggregation parameters are determined for the network socket associated with the application. The network socket is defined based, at least in part, on the socket aggregation parameters. A plurality of packets received from the application associated with the network socket are aggregated. It is determined, based on said aggregating the plurality of packets, whether at least one aggregation limit associated with the socket aggregation parameters is reached. An aggregate packet is provided to a network adapter of the network device to perform segmentation offload in response to said determining that at least one aggregation limit associated with the socket aggregation parameters is reached.

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.
