摘要： A method, system, and program provide for efficient send socket call handling by a transport layer. A transport layer of a network protocol stack receives a send socket call for data of a specified length from an application layer. Responsive to detecting that there is insufficient memory for a single memory allocation to a buffer in the transport layer for at least the specified length, the transport layer blocks the send socket call. The transport layer only wakes the send socket call upon detection of sufficient memory for the single memory allocation within the buffer of the transport layer for at least the specified length, wherein waking the send socket call triggers a kernel to perform the single memory allocation in the buffer and to write the data to the single memory allocation in a single pass.

摘要： In a method of reducing network congestion between a source computer and a destination computer, a receiving router receives a source quench message and determines whether originator of the source quench message is the destination computer or an intermediate router. If the receiving router determines the originator to be the destination computer, the receiving router forwards the source quench message to the source computer. If the receiving router determines the originator to be an intermediate router, the receiving computer determines if there is an alternative route from the receiving router to the destination computer. If the receiving router determines there is no alternative route from the receiving router to the destination computer, the receiving router forwards the source quench message to the source computer. If the receiving router determines there is an alternative route to the destination computer, the receiving router does not forward the source quench message to the source computer, and, going forward, routes packets to the destination computer by the alternative route.

摘要： A NAT data processing system is located behind a NAT enabled network with a NAT device as a gateway to the NAT enabled network. A client system located outside the NAT enabled network queries the NAT device for the address of the NAT data processing system located behind the NAT enabled network. The query is automatically routed through the NAT device to a DNS server. The DNS server returns an address for the NAT data processing system and source routing for the NAT device. The NAT device forwards the address and source routing to the client system. The client system sends packets to the NAT data processing system at the address with source routing through the NAT device, such that the NAT data processing system behind the NAT enabled network is directly accessed by the client system from outside the NAT enabled network.

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： 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 enabling multi-tuple TCP sockets within a computer network is disclosed. All possible connection paths between a first computer and a second computer are initially determined. Then, tuple information of all the possible connection paths are stored in a respective socket of the first and second computers as multi-tuple information. Next, one of the possible connection paths is designated as a preferred path and the remaining possible connection paths are designated as alternate paths. Finally, data packets are transmitted via the preferred path after a TCP connection has been established between the first and second computers on the preferred path.

摘要： A system and method for forwarding URL's to one or more recipients using a Wireless Access Protocol (WAP) network is provided. A mobile user views web pages on his WAP enabled wireless device, such as a mobile telephone or PDA. When the mobile user locates a web page that he prefers to view later or wants to send to another user, the mobile user invokes redirect software which composes a redirect request that includes one or more redirect entries. Each redirect entry corresponds to a redirect address and a URL. When the user finishes with selecting one or more redirect addresses, the mobile device sends the redirect request to a WAP gateway. The WAP gateway receives the redirect requests and forwards the redirect entries to the corresponding redirect addresses over a computer network, such as the Internet.
