摘要： A system and method of responding to a full TCP queue. After a server receives a TCP connection request from a client, the server places the request on an embryonic queue of TCP connection requests sorted by the amount of elapsed time since the server has respond to each respective TCP connection request. When the server attempts to place a new TCP connection request on a full embryonic queue, the host, via the TCP protocol, will remove the entry at the end of the embryonic queue. The last entry, due to the high timer value, is more likely to having performed unsuccessful attempts at completing a connection.

摘要： Administering acknowledgment messages (‘ACKs’) in the Transmission Control Protocol (“TCP”) that include establishing a TCP connection between a sender and a receiver, receiving by the receiver one or more TCP messages from the sender, and transmitting an ACK from the receiver to the sender only when necessary. Administering ACKs in TCP according to embodiments of the present invention may include measuring by the sender a round trip time for transmission of TCP messages between the sender and the receiver and transmitting to the receiver a data-bearing TCP message once per round trip time. Establishing a TCP connection between a sender and a receiver may include measuring by the receiver a round trip time for transmission of TCP messages between the receiver and the sender. Transmitting an ACK only when necessary may include transmitting an ACK when no message from the sender arrives at the receiver for two round trip times.

摘要： An apparatus and method for an improved bulk read socket call are provided. With the apparatus and method, a new field, so_rcvlen, is added to the socket structure that identifies the bulk read size requested by the user. The kernel of the prior art recv( ) function is also modified so that it sets the so_rcvlen to the size requested by the user prior to the recv( ) function going to sleep and waiting for the full data size requested by the user. A new flag, SP_MSGWAITALL, is also provided in the socket structure. In the TCP input processing, when data is received for a particular socket, the current setting of the SP_MSGWAITALL is checked. If the SP_MSGWAITALL flag is set, it is determined whether the amount of data stored in the socket receive buffer is less than the value of so_rcvlen. If not, the TCP input processing does not wake up the recv( ) thread. However, for every alternate segment, the TCP input processing sends back an acknowledgment (ACK). In the TCP output processing, when the SP_MSGWAITALL flag is set and the amount of data in the socket receive buffer is less than so_rcvlen, the full window is advertised. Once the TCP input processing determines that there is at least an amount of data in the socket receive buffer equal to the value of so_rcvlen, the TCP input processing will wake up the recv( ) thread and the SP_MSGWAITALL flag is reset.
摘要翻译：提供了一种改进的大容量读取插座呼叫的装置和方法。使用设备和方法，将新字段so_rcvlen添加到标识用户请求的批量读取大小的套接字结构中。现有技术recv（）函数的内核也被修改，以便在recv（）函数进入休眠状态并等待用户请求的完整数据大小之前，将so_rcvlen设置为用户请求的大小。插座结构中还提供了一个新标志SP_MSGWAITALL。在TCP输入处理中，当为特定套接字收到数据时，将检查SP_MSGWAITALL的当前设置。如果设置了SP_MSGWAITALL标志，则确定存储在套接字接收缓冲区中的数据量是否小于so_rcvlen的值。如果没有，TCP输入处理不会唤醒recv（）线程。然而，对于每个备用段，TCP输入处理发回确认（ACK）。在TCP输出处理中，当设置了SP_MSGWAITALL标志并且套接字接收缓冲区中的数据量小于so_rcvlen时，将通告完整窗口。一旦TCP输入处理确定套接字接收缓冲区中至少有一定数量的数据等于so_rcvlen的值，则TCP输入处理会唤醒recv（）线程，并重置SP_MSGWAITALL标志。

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： 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, 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.
