摘要： A method, system and apparatus for improving data transfer rate over a network are provided. When a piece of data is to be transmitted to a target system, it is divided into a number of packets and a determination is made as to whether the number of packets exceeds a threshold number. If so, the packets are transferred in parallel over a plurality of network connections. The ideal network connections are TCP/IP connections. Thus, each packet has an IP header, which contains an IP identification field. An indicium is placed into the IP identification field for proper reconstruction of the data by the target system.

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： 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： The present invention provides a method and apparatus for multicast tunneling for mobile devices. The method comprises receiving a multicast packet directed to a plurality of mobile nodes, the mobile nodes being associated with a home subnet and identifying if any of the plurality of the mobile nodes are coupled to a subnet other than the home subnet, wherein each of the identified mobile nodes has an associated transmission path through which that mobile node can be reached. The method further provides that in response to determining that at least some of the mobile nodes are coupled to the subnet other than the home subnet, determining which of the identified mobile nodes has a common next hop in their associated transmission path and generating a packet including at least a portion of the multicast packet and including in the packet a list of mobile nodes that have the common next hop. The method further provides for transmitting the generated packet to the common next hop.

摘要： A method, apparatus, and computer instructions for transferring data in a network data processing system. Data is transferred to a destination in which an address resolution protocol entry is used to transfer this data to the destination. A determination is made as to whether the address resolution protocol entry will expire within a selected threshold while transferring data to the destination. If the address resolution protocol will expire within the selected threshold, the address resolution protocol entry is kept or retained to reduce the interruptions or delays in the transferring of the data.

摘要： A method, apparatus, and computer instructions for managing keepalive transmissions. A keepalive packet is received from a remote data processing over a particular connection within a set of connections to the remote data processing system. Timers for each of the set of connections are reset in response to receiving a response to a keepalive packet from the remote data processing system such that only a single keepalive packet is required to maintain all of the plurality of connections with the remote data processing system. In this manner, the number of requests and responses with respect to whether a connection is active is minimized, reducing congestion in a network data processing system.
