摘要： A graphic user interface of a network client (106) includes a stock ticker from a stock server (110) and a news sidebar from a news server (112) over the IP addresses advertised to the client (106) in its list of multi-homed addresses from the video server (104) specified under Stream Control Transmission Protocol (SCTP). The client accepts real-time data from the stock exchange server and the news agency server on the multi-homed IP addresses designated in the association with the video server (104) without knowing that the data is coming from a different source than the video server (104). The real-time data feeds from the video, stock and news servers are aggregated on the client (106) with enhanced speed because the feeds come directly to the client and not via the video server. The operating systems of the home server and remote servers utilize SCTP and specialized commands to implement the enhanced speed of real-time data aggregation being streamed to network clients without requiring modifications to existing client systems.

摘要： TCP congestion avoidance is implemented upon retransmission of a packet and is reverted back to the original congestion state upon receipt of an early acknowledgement (ACK), indicating reordering of packets, thereby eliminating a needless restriction on TCP bandwidth. Upon receiving an ACK to a retransmitted packet, it is determined if the ACK resulted from receipt of the original reordered packet or the retransmitted packet, based on the arrival time of the ACK at the sender. If the round-trip-time (RTT) for the retransmitted packet is much lower than the average or current calculated RTT for the network link between sender and receiver, then the retransmission occurred as a result of a reordering event, and the congestion window is restored back to its value prior to the retransmission, thereby permitting the network link to continue operating at its original increased throughput.
摘要翻译： TCP拥塞避免在分组重传时实现，并且在接收到指示重新排序分组的早期确认（ACK）时被恢复到原始拥塞状态，从而消除对TCP带宽的不必要的限制。在向重传的分组接收到ACK时，基于ACK在发送方的到达时间确定ACK是否从接收到原始重新排序的分组或重传分组而产生。如果重发分组的往返时间（RTT）远低于发送方和接收方之间的网络链路的平均或当前计算的RTT，则重新发送作为重排序事件的结果，拥塞窗口为在重传之前恢复其值，从而允许网络链路以其原始增加的吞吐量继续运行。

摘要： Methods, systems, and media are disclosed for improved granularity of a response-request communication on a networked computer system. One example embodiment includes receiving the request-response communication by the networked computer system, and associating the request-response communication with a port, having a nodelay setting, from a set of ports on the networked computer system. Further, the example embodiment includes enabling, based upon the associating, the nodelay setting upon connection of the request-response communication with the port. Further still, the example embodiment includes sending, in accordance with the enabling, the request-response communication to a destination in communication with the networked computer system. In addition, further example embodiments include configuring the ports on the networked computer system with nodelay values indicating whether a particular port is assigned nodelay or no nodelay for a request portion or request portion of a request-response communication connecting to that particular port.

摘要： A method for improving the efficiency of Internet Protocol Control Block (INPCB) lookup operations at a TCP receiver and TCP sender. The TCP/IP stack is modified such that every data packet generated includes both data and INPCB address information. Specifically, the TCP/IP stacks of a sending device and a receiving device are modified to provide a contemporaneous transmission of INPCB addresses along with each data packet. The TCP/IP stack of the receiver is also modified such that the receiver echoes this INPCB address along with each TCP packet sent back to the sender to eliminate the necessity of an INPCB address lookup operation at the sending device. Contemporaneous transmission of data and INPCB addresses facilitates direct delivery of data packets to the corresponding sockets.

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 IP 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 packets that may be fragmented.

摘要： A computer implemented method, apparatus, and computer usable program code to determine whether an acknowledgment packet from an end point acknowledges receipt of unsent data in response to receiving the acknowledgement packet over a connection with the end point. A determination is made as to whether acknowledgement packets for unsent data have been received sequentially a selected number of times over the connection in response to the acknowledgement packet being for unsent data. The acknowledgment packet is dropped if acknowledgement packets have been received sequentially the selected number of times over the connection.

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： 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。
