摘要： A computer implemented method and data processing system for the detection and recovery of a network interface card TCP acceleration offload failure. Responsive to a failure to receive an acknowledgement of a transmission control protocol segment containing a request for a transmission control protocol offload function in a network interface card, the transmission control protocol segment is retransmitted without the request for a transmission control protocol offload function. When an acknowledgement of the retransmitted transmission control protocol segment without the request for a transmission control protocol offload function is received, a counter is incremented which indicates a failure of the transmission control protocol offload function. Responsive to the counter exceeding a predefined number of allowed failures, all requests to the transmission control protocol offload function for the network interface card are stopped.

摘要： A receiving host in a TCP/IP network sends an acknowledgment indicating a received data packet is corrupt. The sending host will begin transmitting with a new field set in the IP header called a check-TCP-checksum bit, thereby requesting that all routers in the TCP/IP network perform a checksum on the entire received packet. Routers in the TCP/IP network will perform a complete checksum on an entire packet with the check-TCP-checksum bit set, and not just on the IP header. The routers continuously monitor the ratio of corrupt packets received on a particular port that fail the entire packet checksum to the total number of packets received on that port. If the ratio of corrupt-to-received packets exceeds a corruption threshold, the router assumes that the associated link is causing data corruption and issues a routing update indicating that the link is bad and should be avoided. Once the retransmission rate between the sender and receiver drops below a threshold level, the bad link has been detected and avoided within the TCP/IP network and the check-TCP-checksum option in the IP header is no longer set in data packets transmitted to the receiver host.
摘要翻译： TCP / IP网络中的接收主机发送指示接收到的数据包已损坏的确认。发送主机将开始使用称为检查TCP校验和位的IP报头中设置的新字段进行发送，从而请求TCP / IP网络中的所有路由器对整个接收到的数据包执行校验和。 TCP / IP网络中的路由器将对整个数据包执行完整的校验和，同时检查TCP-checksum位，而不仅仅是在IP报头上。路由器连续监视在特定端口上接收的损坏数据包的总数与在该端口上接收的数据包的总数之间的比例。如果损坏的数据包的比例超过了破坏阈值，则路由器假设相关联的链路导致数据损坏，并发出路由更新，指示链路不良，应该避免。一旦发送方和接收方之间的重传速率下降到阈值以下，就会在TCP / IP网络内检测并避免不良链路，并且IP报头中的check-TCP-checksum选项不再被设置在发送到接收主机。

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 mutli-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： A multi-display system and method supporting differing accessibility feature selection provides a suitable display for a user with limited visual acuity, while providing a second display having a different accessibility feature set to a second user. An application or operating system checks selected accessibility features and display settings corresponding to each graphical display device and generates multiple graphical outputs in conformity with program output and the corresponding accessibility features and display settings for each device. One graphical display may be a personal computer display and the other a projector, so that an accessible desktop can be presented to the presenter, while the presentation can be shown with a desired set of attributes. The operating system may support the above-described operation by generating the multiple display outputs from the accessibility settings and a single program output. Alternatively, an application can generate two display outputs in conformity with accessibility selections.

摘要： A method for processing data packets in an interception proxy server without using a Network Address Translation module. A TCP packet received at a router is encapsulated using generic routing encapsulation (GRE). The TCP packet is redirected to a proxy server through a GRE tunnel which includes a redirection rule comprising a local destination IP address and port to be used for traffic passed through the tunnel. When the proxy server receives the TCP packet, the TCP packet is decapsulated. If a flag is set in the payload header of the TCP packet indicating that a redirection rule has been configured for traffic passed through the tunnel, the payload header of the TCP packet is modified according to the redirection rule. The modified TCP packet is then passed to a transmission control protocol of the proxy server.
摘要翻译：一种在拦截代理服务器中处理数据包而不使用网络地址转换模块的方法。使用通用路由封装（GRE）封装在路由器处接收到的TCP数据包。 TCP数据包通过GRE隧道重定向到代理服务器，GRE隧道包括重定向规则，包括本地目的IP地址和端口，用于通过隧道的流量。当代理服务器接收到TCP数据包时，TCP数据包被解封装。如果在TCP数据包的有效载荷头部中设置了一个标志，表示已经为通过隧道的流量配置了重定向规则，则根据重定向规则修改TCP数据包的有效负载报头。修改的TCP数据包然后传递给代理服务器的传输控制协议。

摘要： A solution for managing a communications connection, in which one or more acknowledgements are filtered is provided. In particular, data can be obtained for forwarding to a remote device, and at least some of the data can be communicated for processing on the remote device. Subsequently, an acknowledgement is received for the at least some of the data, and a determination is made as to whether to forward the acknowledgement based on an optimization configuration. The invention can include several checks to ensure that any acknowledgement that should be forwarded for further processing is properly forwarded. In one embodiment, the invention is implemented on a network adapter, and enables numerous acknowledgements that are received by the network adapter for a large send data packet to be filtered and not provided to a protocol stack.

摘要： Methods, systems, and media to reduce delays associated with port assignments are disclosed. More specifically, embodiments include hardware and/or software to delay binding of selected port numbers to instances of applications. Some embodiments identify port numbers for which applications generate multiple bind calls that may connect with unique remote ports. The port numbers are stored in a port list that is accessible to the protocol stack and memory is allocated for storing flags and additional port configuration data. When a bind call is associated with a port number bound to another application instance and the port number is included in the port list, the bind call may then be delayed until a connect is received from the corresponding application instance. When the resulting four tuple is unique for the computer system, the corresponding application instance is bound to the port number and connected with the remote port.
