摘要： A number of improvements in network adapters that offload protocol processing from the host processor are provided. Specifically, a mechanism for improving connection establishment in a system utilizing an offload network adapter is provided. The connection establishment mechanism provides the ability to offload connection establishment and maintenance of connection state information to the offload network adapter. As a result of this offloading of connection establishment and state information maintenance, the number of communications needed between the host system and the offload network adapter may be reduced. In addition, offloading of these functions to the offload network adapter permits bulk notification of established connections and state information to the host system rather than piecemeal notifications as is present in known computing systems.

摘要： A number of improvements in network adapters that offload protocol processing from the host processor are provided. Specifically, mechanisms for handling memory management and optimization within a system utilizing an offload network adapter are provided. The memory management mechanism permits both buffered sending and receiving of data as well as zero-copy sending and receiving of data. In addition, the memory management mechanism permits grouping of DMA buffers that can be shared among specified connections based on any number of attributes. The memory management mechanism further permits partial send and receive buffer operation, delaying of DMA requests so that they may be communicated to the host system in bulk, and expedited transfer of data to the host system.

摘要： An apparatus for relaying a hashed message from a first node to a second node, comprising an inlet interface for receiving a message from the first node, a hash number calculator for hashing the message from the inlet interface, an outlet interface for sending the hashed message to the second node, a first one-way data link for unidirectional transfer from the inlet interface to the hash number calculator, and a second one-way data link for unidirectional transfer from the hash number calculator to the outlet interface, is provided. The apparatus provides a secure mechanism and communication channel for relaying hashed acknowledgment messages from a receive node to a send node to inform the status of data transfer from the send node to the receive node across a one-way data link. The apparatus may be further implemented with the capability of comparing hashed messages from the two nodes.

摘要： A system transfers data between a client computer and a server computer over a network, wherein communications are established over a first data link between the client and the server to provide the server with identification of the data to be transferred, then communications are established over a second data link between the client and the server for data transfer such that the second data link has a faster data transfer rate than the first data link, then the identified data is transferred from the client to the server; and then finally the client computer is provided with status information relating to the transfer of the identified data. The first data link is sufficient to support normal data operations utilizing existing network resources. The second data link can connect the clients to one or more of the servers, or may connect only particular clients and servers with special needs for large data transfer. The system provides efficient transfer of large data blocks from clients to servers over the network, without disruption to normal data operations and without a requirement for extensive and expensive resource upgrades or cumbersome and inconvenient archive methodologies.

摘要： A method for performing fine grain time adjustments in computer systems. A fine grain time adjustment can be completed in the first interrupt instead of doing it piecewise over many interrupts. If the adjustment offset is less than or equal to a threshold, then the clock is adjusted in the first clock interrupt; if the adjustment offset is greater than the threshold, then the clock is adjusted over a number of interrupts with an adjustment by an amount equal to the threshold per interrupt.

摘要： A bilateral data transfer system comprising a first node, a second node, a first one-way link for unidirectional transfer of first data from the first node to the second node, and a second one-way link for unidirectional transfer of second data from the second node to the first node, wherein the unidirectional transfer of the first data across the first one-way link and the unidirectional transfer of the second data across the second one-way link are independently administered by the bilateral data transfer system. Under such bilateral data transfer system, each of the one-way data links may be subject to separately administered security restrictions and data filtering processes. Hence, it enables secure bilateral communications across different network security domains.
