摘要:
A mechanism is provided to enhance the scalability of network caching capabilities. All network client applications running on a partition in a virtualized environment are configured to query information from a single virtual input/output server (VIOS) network caching daemon. Thus, the illustrative embodiments provide a 1:n model where a VIOS partition has a network caching daemon, and each of the n partitions uses the network caching daemon of the VIOS partition. The mechanism of the illustrative embodiments only requires the system administrator to control one copy of the local files on the VIOS server. The system administrator does not need to monitor all of these local files on each individual partition. The system administrator consolidates the entries used by the different individual partitions into one single file on the VIOS server side.

A method, apparatus, and computer program product in a data processing system for improving response time when clients use network services. If a load level exceeds a load transfer level, the method causes the server to refuse a corresponding percentage of incoming requests received. Then the method sends a message to the requesting client for each refused incoming request, wherein the message requests the requesting client to resend the refused incoming request to a secondary server.

A method, computer program product, and a data processing system for activating a screensaver in a data processing system is provided. A timeout value that defines an idle interval after which a screensaver is to be activated is set. An analysis of contents of a video memory is performed. The timeout value is adjusted responsive to the analysis.

Provided are techniques for physically coupling, via a docking port, a first stand-alone computing device to a communication bus coupled to a set of processing resources; detecting, by the communication bus, the coupling; responsive to the detecting of the coupling, correlating the stand-alone computing device to a subset of the set of processing resources; signaling, by the communication bus, each resource of the subset of the coupling; and responsive to the signaling, dynamically configuring the stand-alone computing device and each resource of the subset to enable the stand-alone computing device to utilize each resource of the subset.
摘要:
A method of choosing a domain name server to resolve a name resolution request includes receiving a name resolution request and associating at least one domain name server listed in a domain name server table with a timestamp. The method further includes accessing a domain name server from the domain name server table based on the timestamp. A system including means for accomplishing similar actions is also disclosed.

An approach is provided to improve network efficiency. A send segment size, such as a maximum segment size (MSS), that corresponds to data segments being sent to a receiver over a computer network. A data block is identified in a send buffer and the data block includes more than one data segments. Based on the determined send segment size, all but a remaining data segment of the data segments are sent to the receiver. The sent data segments are each the determined send segment size and the remaining data segment is smaller than the send segment size. The remaining data segment is sent to the receiver in response to identifying that the remaining data segment is a portion of the data block.
摘要:
In a method for regulating network bandwidth in a virtualized computer environment, a computer having a hypervisor program receives a request from a first virtual client to transmit data. In response, the computer transfers the data from a memory of the first virtual client to a memory of a virtual server. The computer receives an error notification from a shared virtual network adapter of the virtual server, indicative of insufficient network bandwidth available to transmit the data. In response, the computer notifies the first virtual client that insufficient network bandwidth is available to transmit the data.
