摘要： Administering acknowledgment messages (‘ACKs’) in the Transmission Control Protocol (“TCP”) that include establishing a TCP connection between a sender and a receiver, receiving by the receiver one or more TCP messages from the sender, and transmitting an ACK from the receiver to the sender only when necessary. Administering ACKs in TCP according to embodiments of the present invention may include measuring by the sender a round trip time for transmission of TCP messages between the sender and the receiver and transmitting to the receiver a data-bearing TCP message once per round trip time. Establishing a TCP connection between a sender and a receiver may include measuring by the receiver a round trip time for transmission of TCP messages between the receiver and the sender. Transmitting an ACK only when necessary may include transmitting an ACK when no message from the sender arrives at the receiver for two round trip times.

摘要： A method, apparatus, and computer instructions for reactivating an existing connection to a remote data processing system. A data packet is created using a previously acknowledged sequence number for the connection. The sequence number is used to uniquely number data bytes sent in a connection, such as a TCP connection. With this sequence number, devices and components, such as routers and fire walls will forward the packet to the destination. A special data sequence, such as a MAC address of the remote data processing system repeated a selected number of times, is placed in the data packet. This special data sequence causes the remote data processing system to wake up from a sleep mode when received by the remote data processing system. The data packet is sent to the remote data processing system using the existing connection. The use of a subnet directed broadcast is avoided. Thus, problems associated with routing wake up packets are avoided.

摘要： Methods, systems, and products are provided for tunneling IPv6 packets. Embodiments include receiving, by an origin IPv6 border router from an origin IPv6 host, an IPv6 packet having an IPv6 destination address; receiving, by an origin IPv6 border router from an origin IPv6 host, an IPv4 address for a destination IPv6 border router retrieved from a data structure associating IPv6 destination addresses with IPv4 addresses for destination IPv6 border routers; encapsulating, by the origin IPv6 border router, the IPv6 packet in an IPv4 packet; and sending the encapsulated packet to a destination IPv6 border router at the IPv4 address. In many embodiments, encapsulating, by the origin IPv6 border router, the IPv6 packet in an IPv4 packet is carried out by adding an IPv4 header to the IPv6 packet.

摘要： A method, system, and computer program product for delivering data, received from a network on a network adapter to a pre-assigned port, to a storage buffer assigned to an application are disclosed. An application designates an application-specific buffer within a local data processing system for buffering data communicated with the application. The local data processing system reports to a network interface of the local data processing system a memory address of the designated application-specific buffer, and the data processing system designates a port on which to receive packets addressed to the memory address. The data processing system then sends a port registration message to the local network interface, enabling the network interface to compare the port number of incoming traffic to a registered port number and route incoming traffic from a remote data processing system directly to the designated application-specific buffers in the event of a match. In one embodiment, the present invention includes receiving in the network interface a packet addressed to the specific port and delivering data from the packet to said application-specific buffer.

摘要： A method, data processing system, and computer usable code are provided for protocol definition for software bridge failover. In a first aspect of the present invention, a first software bridge determines the proper working operation of a physical adapter. Limbo packets are sent to a second software bridge alerting the second software bridge that the first software bridge is no longer bridging traffic responsive to the physical adapter failure in the first software bridge. The second software bridge receives the limbo packets, and, in response to receiving the limbo packets, asserts primary control and initiates bridging of traffic. In an alternative aspect of the present invention a first software bridge sends keep-alive packets. A second software bridge monitors the keep-alive packets from the first software bridge and, in response to a failure to detect the keep-alive packets from the first software bridge, the second software bridge initiates bridging of traffic.

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.
