    Abstract: A method, system, and product in a data processing system are disclosed for managing data transmitted from a first end node to a second end node included in the data processing system. A logical connection is established between the first end node and the second end node prior to transmitting data between the end nodes. An instance number is associated with this particular logical connection. The instance number is included in each packet transmitted between the end nodes while this logical connection remains established. The instance number remains constant during this logical connection. The instance number is altered, such as by incrementing it, each time a logical connection between these end nodes is reestablished. Thus, each packet is associated with a particular instance of the logical connection. When a packet is received, the instance number included in the packet may be used to determine whether the packet is a stale packet transmitted during a previous logical connection between these end nodes.

    Abstract: A method, system, and product in a data processing system for managing data transmitted from a first end node to a second end node included in the data processing system. A logical connection is established between the first end node and the second end node prior to transmitting data between the end node s. An instance number is associated with the logical connection and included in each packet transmitted between end nodes while this connection remains. The number remains constant during this connection, but is altered, such as by incrementing it, each time a logical connection between these end nodes is reestablished. Each packet is associated with a particular instance of the logical connection and when it is received, the number may be used to determine whether the packet is a stale packet transmitted during a previous logical connection between these end nodes.

    Abstract: A method and system for transmitting and receiving data from a host computer system to an Ethernet adapter are provided. The method comprises establishin g a connection between the host system and the Ethernet adapter pushing a transmit or receive request message from a host system device driver to the Ethernet adapter's request queue. Access to host memory is transferred to th e Ethernet adapter. If data is being transmitted to the Ethernet adapter, the adapter reads the data from a location in host memory specified in the transmit request message, and then transmits the data onto transmission medi a (e.g. wire, fiber). If the request message is a receive request, the adapter reads the data from the media and then sends the data into host memory at th e location specified in the receive request message. When the data transfer is complete, the adapter sends a response message back to the host. The respons e message includes a transaction ID which is used by the host device driver to associate the response message to the original request message.
