摘要： A computer implemented method, apparatus, and computer usable program code for managing a software partition in logical partitioned data processing system. A virtual root process is created for the software partition, wherein the virtual root process functions as a root process for the software partition. The set of child processes is re-parented to the virtual root process in response to termination of a process having a set of child processes.

摘要： A method for improving the efficiency of Internet Protocol Control Block (INPCB) lookup operations at a TCP receiver and TCP sender. The TCP/IP stack is modified such that every data packet generated includes both data and INPCB address information. Specifically, the TCP/IP stacks of a sending device and a receiving device are modified to provide a contemporaneous transmission of INPCB addresses along with each data packet. The TCP/IP stack of the receiver is also modified such that the receiver echoes this INPCB address along with each TCP packet sent back to the sender to eliminate the necessity of an INPCB address lookup operation at the sending device. Contemporaneous transmission of data and INPCB addresses facilitates direct delivery of data packets to the corresponding sockets.

摘要： A method, apparatus, and computer instructions are provided for propagating a physical device's link status to one or more virtual devices associated with the physical device. Link status information about the physical device indicating a failure in the physical device is identified using partition management firmware. The link status information about the physical device is propagated by partition management firmware to one or more virtual devices associated with the physical device. The logical partition using the virtual device use the virtual device link status to determine if a physical link to an outside network is down, and take appropriate remedial actions as may be necessary.

摘要： A method, system and apparatus for maintaining a two-byte identification field of IP headers when a Gigabit Ethernet is in use are provided. Since the IP identification field is of two bytes, there is a limited number of identification numbers that may be used. Due to the high data transfer rate of the Gigabit Ethernet, this number may be reached within one second. Hence, there may be a possibility that two or more packets may have the same identification number while in transit. In a representative embodiment, one identification number is used for packets that may not be fragmented; thus, freeing the rest of the numbers for packets that may be fragmented.

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： 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： An apparatus and method for an improved bulk read socket call are provided. With the apparatus and method, a new field, so_rcvlen, is added to the socket structure that identifies the bulk read size requested by the user. The kernel of the prior art recv( ) function is also modified so that it sets the so_rcvlen to the size requested by the user prior to the recv( ) function going to sleep and waiting for the full data size requested by the user. A new flag, SP_MSGWAITALL, is also provided in the socket structure. In the TCP input processing, when data is received for a particular socket, the current setting of the SP_MSGWAITALL is checked. If the SP_MSGWAITALL flag is set, it is determined whether the amount of data stored in the socket receive buffer is less than the value of so_rcvlen. If not, the TCP input processing does not wake up the recv( ) thread. However, for every alternate segment, the TCP input processing sends back an acknowledgment (ACK). In the TCP output processing, when the SP_MSGWAITALL flag is set and the amount of data in the socket receive buffer is less than so_rcvlen, the full window is advertised. Once the TCP input processing determines that there is at least an amount of data in the socket receive buffer equal to the value of so_rcvlen, the TCP input processing will wake up the recv( ) thread and the SP_MSGWAITALL flag is reset.

摘要翻译： 提供了一种改进的大容量读取插座呼叫的装置和方法。 使用设备和方法，将新字段so_rcvlen添加到标识用户请求的批量读取大小的套接字结构中。 现有技术recv（）函数的内核也被修改，以便在recv（）函数进入休眠状态并等待用户请求的完整数据大小之前，将so_rcvlen设置为用户请求的大小。 插座结构中还提供了一个新标志SP_MSGWAITALL。 在TCP输入处理中，当为特定套接字收到数据时，将检查SP_MSGWAITALL的当前设置。 如果设置了SP_MSGWAITALL标志，则确定存储在套接字接收缓冲区中的数据量是否小于so_rcvlen的值。 如果没有，TCP输入处理不会唤醒recv（）线程。 然而，对于每个备用段，TCP输入处理发回确认（ACK）。 在TCP输出处理中，当设置了SP_MSGWAITALL标志并且套接字接收缓冲区中的数据量小于so_rcvlen时，将通告完整窗口。 一旦TCP输入处理确定套接字接收缓冲区中至少有一定数量的数据等于so_rcvlen的值，则TCP输入处理会唤醒recv（）线程，并重置SP_MSGWAITALL标志。

摘要： A method and apparatus is provided for enabling a telephone caller to generate a brief message for transmission to an intended call recipient, as part of the initial procedure of setting up a phone call between the caller and recipient. The message is sent and displayed or otherwise made available to the recipient before the recipient is required to answer the call. The message could comprise a sequence of alphanumeric characters that conveyed an abbreviated message, or otherwise indicates the purpose to the call to the recipient or provides other information. Respective characters could be transmitted as corresponding sequences of binary tones sent to the call recipient between telephone rings.

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 and system for providing subgroup conversation during a teleconference enables side conversations during a virtual meeting. A passcode is used by parties to join the subgroup conversation, so that privacy of the subgroup is maintained. Alternatively, an administrator may set up subgroups and either join or invite members, who may toggle between the main teleconference and a subgroup teleconference using a standardized user input. The system may be implemented in any telephone network and across telephone networks such as public switched telephone networks (PSTNs), wireless networks, voice over Internet protocol networks and/or private branch exchanges (PBXs).
