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 memory registration abstraction layer includes decision logic for dynamic, efficient determination of memory copy versus registration. The exemplary embodiments apply to direct memory access environments. The memory registration abstraction layer also includes tracking logic for monitoring the usage history for certain ranges of memory registration requests. The registration logic chooses to copy memory or map memory based on training and observation of application behavior, taking the more efficient performance path without requiring changes to the application.

摘要： Disclosed is a virtual world server receives an update signal corresponding to an RFID tag. The virtual world server determines an RFID tag identifier, an RFID reader identifier, and an associated asset name from the update. The virtual world server looks up a virtual area associated with the RFID reader identifier. The virtual world server teleports a virtual asset associated with the RFID tag identifier to a virtual area in the virtual world. The virtual world server renders a model of the asset in a virtual world based on an avatar perspective.

摘要： Managing subscriber access to online subscription services providing online subscribers or potential new subscribers access to a subscription or trial subscription content at a normal level of service during the subscription period but, after the subscription has expired, providing a decreased level of service during a post-expiration period. The level of service may be decreased incrementally by reducing the content available to a subscriber, downloading the subscription content at a slower than normal rate, delivering certain features in black and white instead of color, deleting sound files, disabling any inter-active features, or any combination of these features. A subscription server manages the various databases and downloads subscription content to the online subscribers. The databases contain information about the subscribers and instructions for the subscription server to follow in granting normal or reduced access to the subscription content.

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： 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 mechanism is provided for augmenting the mail header of a message with a list of digital signatures representing the chain of contributors to the message. The augmented header may also encode the actual contributions corresponding to each digital signature. The list is appended every time a message is forwarded. If a message has a portion with no corresponding digital signature or if one or more of the digital signatures is not trusted, the user may handle the message accordingly. Furthermore, a mail server or client may discard a message if the number of digital signatures exceeds a threshold to filter out unwanted messages, such as e-mail chain letters.

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 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.
