Abstract: Techniques are described that can be used to enable a transfer of an operating system from one machine to another. The transfer permits the operating system to be available to the target machine at buffers that are accessible to one or more application or other logic. In some implementations, information related to an operating system migration is stored in a buffer that is accessible to an application that is to use the information and thereby avoids a copy of such information from an intermediate buffer to an application buffer.

Abstract: In one aspect of the invention is a method for selecting a site in a network based on the IP (Internet Protocol) of a requesting system. When a request for data is made from a requesting system, the requesting system's IP address is used to determine if an edge server, that is, a streaming server co-located with the requesting system's Web host, exists for the requesting system. If an edge server for the requesting system exists, then the requesting system receives the requested data from the edge server. If no edge server exists, then the requesting system receives the requested data from a deployment server.

Abstract: Apparatus and method for a first device to query a second device for the availability of a hardware feature within the second device, and for the second to receive and analyze the query to determine whether or not to respond, depending on the version of hardware feature sought, a code identifying a vendor, etc., and responding with a reply providing an indication of availability of the hardware feature and/or an address at which the hardware feature may be accessed, if the determination is made to reply.

Abstract: A system, method and apparatus for prioritizing transactions is disclosed. I/O devices may generate transactions with a stream identifier. A transaction classifier may assign a priority to a transaction based upon a stream identifier of the transaction. An arbiter may select a transaction for processing based upon priorities assigned to the transaction.

Abstract: Write-combining in a computer system that uses a push model is set forth herein. In one embodiment, the method comprises creating one or more packets having a descriptor and the data associated with detected write transactions stored in the buffer assigned to a write-combinable range in response to a flush request to flush the buffer, and sending (pushing) these packets to the network I/O device.

Abstract: Provided are techniques for interrupt processing. An Input/Output device determines that an event has occurred. The Input/Output device determines a processor identifier and determines an event data structure identifier for an event data structure into which data for the event is stored using the processor identifier. The Input/Output device also determines a vector identifier for an interrupt message vector into which an interrupt message for the event is written. Then, interrupt message data is written to the interrupt message vector to generate an interrupt.

Abstract: According to some embodiments, a protocol control block is speculatively pre-fetched from an external memory unit.
