摘要： The reassembly timer in a TCP/IP receiver is dynamically set to avoid data corruption on fast networks caused by IP identification wrap-around. A sender generates IP packets with a special option specifying a reassembly time for fragments based on the subnet of the destination or on the calculated round-trip time of the connection. A receiver sets the reassembly timer to the reassembly time specified in the option. A sender can generate IP packets with an alternative option setting a time stamp for the generated packet. A receiver calculates a traversal time based on the difference between the arrival time of the fragment and this time stamp, and sets the reassembly timer based on this traversal time. A receiver can independently set the reassembly timer to a first reassembly time set by the user for fast networks or to a second reassembly timer set by the user for slow networks based on whether the receiver and sender are on the same subnet.
摘要翻译： TCP / IP接收器中的重组定时器被动态设置，以避免由IP识别环绕引起的快速网络上的数据损坏。发送方生成具有特殊选项的IP数据包，指定基于目的地的子网或连接的计算出的往返时间的片段的重组时间。接收机将重新组装定时器设置为选项中指定的重新组装时间。发送方可以使用替代选项生成IP数据包，为生成的数据包设置时间戳。接收机根据片段的到达时间与该时间戳的差异来计算遍历时间，并根据该遍历时间设置重新组装定时器。接收机可以基于接收机和发送机是否在相同的子网上，将快速网络或由用户为慢速网络设置的第二重组定时器独立地设置为由用户设置的第一重组时间。

摘要： A system, method, and program product is provided that requests, by a first computer system, a new network session with a second computer system. The new network session request occurs after a previous network session between the two systems and the new network session request includes a new sequence number that is different from a previous sequence number that was used during the previous network session. The first computer system receives an acknowledgement from the second computer system that references the previous sequence number instead of the new sequence number. In response to receiving the acknowledgement at the first computer system that references the previous sequence number, the first computer system modifies the new sequence number by setting it to a value that is higher than the previous sequence number, and the first computer system re-requests the new network session using the modified new sequence number.

摘要： A method for virtual segmentation off-load in a logically partitioned data processing system is provided. A data transmission protocol stack formats a data message for segmentation off-load to form a virtual segmentation off-load package. The size of the data message is larger than a size of a maximum transmission unit. A partition manager firmware copies the virtual segmentation off-load package from a first logical partition to a virtual Ethernet adapter associated with a second logical partition. The virtual segmentation off-load package is copied without performing a segmentation operation on the data message associated with the virtual segmentation off-load package.

摘要： A method, system, and product are described for alleviating router congestion when the router is processing packets transmitted by computer systems having a congestion notification capability. The router marks packets transmitted between a first computer system and a second computer system when the first and second computer systems have the congestion notification capability. The marking indicates that the router is moderately congested. A marked packet is then received by the first computer system. The router then drops packets transmitted by the first computer system when the packets were transmitted subsequent to the receipt of the marked packet.

摘要： A host enables any adapter of multiple adapters of the host to concurrently support any VIPA of the multiple VIPAs assigned to the host. Responsive to a failure of at least one particular adapter from among the multiple adapters, the host triggers the remaining, functioning adapters to broadcast a separate hardware address update for each VIPA over the network, such that for a failover in the host supporting the multiple VIPAs the host directs at least one other host accessible via the network to address any new packets for the multiple VIPAs to one of the separate hardware addresses of one of the remaining adapters.

摘要： The present invention provides receiving and transmitting devices for providing fragmentation at a transport level along a transmission path. The transmitting device comprises an interface and a control unit coupled to the interface. The control unit is adapted to negotiate a packet size with a remote device. The control unit is also adapted to transmit a data packet of up to the negotiated size. The control unit is further adapted to receive acknowledgments from the remote device associated with one or more fragments, fragmented at the transport-level, of the transmitted data packet. The receiving device comprises an interface and a control unit coupled to the interface. The control unit is adapted to receive two or more fragments of a data packet transmitted by a remote device. The control unit is also adapted to transmit one or more acknowledgments to the remote device based on the received fragments.

摘要： The present invention provides a method and apparatus for providing fragmentation at a transport level along a transmission path. The method comprises receiving a data packet from a first remote device for transmission to a second remote device, wherein the data packet includes a transport-level protocol packet encapsulated in a network-level protocol packet and determining if a size of the received data packet is greater than a maximum transmission unit (MTU) value. The method further comprises performing fragmentation of the data packet at a transport-level protocol into two or more fragments in response to determining that the size of the received data packet is greater than the MTU value and transmitting one or more of the fragments to the second remote device.

摘要： A computer implemented method, data processing system, and computer program product for efficiently using disk space when unarchiving files in the same file system. An archive file is read to identify a total number of data files in the archive file. The number of headers in the archive file is determined based on the total number of data files. A location in a first disk space of a largest data file in the archive file is determined from an offset in a header corresponding to the largest data file. The largest data file is then copied from the first disk space to a second disk space. The first disk space occupied by the largest data file is then released by truncating the archive file. The obtaining, copying, and releasing steps are repeated for each data file in the archive file until all of the data files are unarchived.

摘要： A method, system and apparatus for improving data transfer rate over a network are provided. When a piece of data is to be transmitted to a target system, it is divided into a number of packets and a determination is made as to whether the number of packets exceeds a threshold number. If so, the packets are transferred in parallel over a plurality of network connections. The ideal network connections are TCP/IP connections. Thus, each packet has an IP header, which contains an IP identification field. An indicium is placed into the IP identification field for proper reconstruction of the data by the target system.
