摘要： The server side Transfer Control Protocol is modified so that the server returns a SYNACK message with the window size equal to zero if the server is busy. When a client sends a TCP connection request and receives a synchronization acknowledgement message with the window size equal to zero, the client knows that the server received the connection request and that the server is busy. The client may then send an acknowledgement message to complete the three-way synchronization handshake, thus successfully completing the connection. Thereafter, the client side TCP may probe the server side TCP until a window update message is received from the server. When the server sends a window update message to set the window size to a non-zero size, the client knows that the server is no longer busy and the client application may then use the TCP connection.

摘要： A data processing network and system in which a network connection is enabled to migrate among a multitude of available servers and/or clients to provide the connection using the most efficient available set of resources. Typically a server and client would indicate their respective support of this connection migration feature when the connection is established. An operating system or application program would monitor existing connections for characteristics including basic functionality and performance. If an existing connection were found to be faulty or low performing and the client and sever associated with the connection supported connection migration, the software would then determine if an alternative and more effective connection existed. Upon discovering such a connection, the parameters that define the connection would be altered to migrate the connection to the preferred hardware. In an embodiment in which the network connections are established with a transmission control protocol (TCP), each connection includes a four-tuple that completely defines the connection, namely, a source IP address, a source port number, a destination IP address, and a destination port number. By altering one or more of the connection's defining four-tuple, the invention is configured to migrate the connection to a NIC or system that is functioning more efficiently.

摘要： A system in which a DHCP server executes a recovery routine after detecting a corrupted IP address state database. The routine determines whether an IP address is assigned to a DHCP client by querying an IP address/port reserved for DHCP clients. If the response suggests the absence of a DHCP client, the address is marked as BAD. If the response suggests the presence of a DHCP client, the IP database is updated appropriately. The query may comprise sending a TCP/IP packet to the IP address and port and monitoring for an ICMP error message. In another embodiment requiring a protocol extension, the DHCP server issues a DHCP supported query to each IP address that responds to a ping command. The DHCP clients supporting this protocol extension will respond to the query by returning all of the DHCP configuration information that was acquired before the IP address state database crashed.

摘要： A data processing system for resending a previously sent email message. A new recipient for the previously sent email message is selected. The new recipient of the previously sent email message is added in response to selecting the new recipient, wherein the previously sent email message is directed to the new recipient and a previous recipient. An indicator to the previously sent email message is added in response to selecting the new recipient, wherein the indicator indicates that the new recipient has been added to a form a new version of the previously sent email message. The new version of the previously sent email message is sent in response to adding the indicator, wherein the indicator causes the new version of the previously sent email message to replace the previously sent email message at an email program of the previous recipient.

摘要： A method, system and apparatus for multicasting or broadcasting a piece of data from one partition of a partitioned computer system to a plurality of partitions of the system are provided. When a partition needs to transfer data to more than one partition of the system, the partition first stores the data into a global memory accessible by all partitions of the system. The memory is then marked nullread-onlynull to ensure that the data is not over-written and the Ids (identifications) of the recipient partitions are passed to a piece of firmware or hardware of the computer system. This firmware or hardware then alerts the recipient partitions that there is a piece of data ready to be read in the memory. Once all the recipient partitions have read the data, the global memory is reverted to a nullreadnull and nullwritenull memory.

摘要： A method, system and apparatus for maintaining a two-byte identification field of IP headers when a Gigabit Ethernet is in use are provided. Since the identification field is of two bytes, there is a limited number of identification numbers that may be used. Due to the high data transfer rate of the Gigabit Ethernet, this number may be reached within one second. Hence, there may be a possibility that two or more packets may have the same identification number while in transit. In a representative embodiment, one identification number is used for packets that may not be fragmented. Thus, freeing the rest of the numbers for the packets that may be fragmented. Consequently, before the IP header is added to the packet, a check is made to determine whether the packet may be fragmented. If so, a unique identification number is used in the identification field of the IP header. If not, a non-unique number is used. The non-unique number is used for all packets that may not be fragmented.

摘要： A method, system and apparatus for improving network performance of a multiprocessor system that has a limited number of physical network interfaces by using virtual IP addresses are provided. When a processor of the multiprocessor system determines that it is processing network data, it uses a virtual IP address to transmit the data. The virtual IP address is associated with a buffer; and thus the data is sent to the buffer. This allows the processor to be free to process other data, network or otherwise. The buffer, with the help of a controller, then contends for the use of one of the limited physical network interfaces to transmit the data.

摘要： A method, system and apparatus for negotiating parameters for an IPSec connection between a requesting client and an iSCSI system using a computer system other than an iSCSI system are provided. By design, the iSCSI system monitors TCP (Transmission Control protocol) port 500 for secure requests. When a request enters port 500, the iSCSI system transmits all information received on port 500 to a computer system better suited to handle IPSec parameter negotiations. After the computer system has negotiated the parameters, the parameters are passed to the iSCSI system for a secure data transaction to ensue.
