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.
摘要翻译： 网络客户端（106）的图形用户界面包括来自库存服务器（110）的股票行情和来自新闻服务器（112）的新闻侧栏，通过在其列表中通告给客户端（106）的IP地址， 来自在流控制传输协议（SCTP）下指定的视频服务器（104）的归属地址。 客户端接收来自证券交易所服务器和通讯社服务器的与视频服务器（104）相关联指定的多归属IP地址的实时数据，而不知道数据来自与视频服务器不同的源 （104）。 来自视频，股票和新闻服务器的实时数据馈送以高速度聚合在客户端（106）上，因为馈送直接进入客户端而不是经由视频服务器。 家庭服务器和远程服务器的操作系统使用SCTP和专用命令来实现流式传输到网络客户端的实时数据聚合的增强速度，而不需要修改现有的客户端系统。

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： 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.

摘要： A method, computer program product, and data processing system for efficiently discovering and storing path MTU information in a sending host are disclosed. In a preferred embodiment, two path MTU tables are maintained. One path MTU table contains MTU values corresponding to the first-hop routers associated with the sending host. The other path MTU table contains MTU values corresponding to individual destination hosts. When the sending host needs to send information to a destination, it first consults the MTU table associated with individual destination hosts. If an entry for that destination host is found in the table, the sending host uses that MTU value. If not, the sending host consults the MTU table for the first-hop router on the path to the destination host and uses that MTU value. If that MTU value is too high, a new entry is made in the host-specific MTU table for the destination host.

摘要： Responsive to receiving a request for a data communications connection, a data communications module of a receiver determines whether a sender of the request is local or remote with respect to the receiver. The data communications module also determines whether a location response flag indicates local or remote. If the relative location of the sender with respect to the receiver corresponds with the location response flag, then the data communications connection is allowed. Otherwise, the connection is not allowed.

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.
