摘要： A graphic user interface of a network client (106) includes a stock ticker from a stock server (110) and a news sidebar from a news server (112) over the IP addresses advertised to the client (106) in its list of multi-homed addresses from the video server (104) specified under Stream Control Transmission Protocol (SCTP). The client accepts real-time data from the stock exchange server and the news agency server on the multi-homed IP addresses designated in the association with the video server (104) without knowing that the data is coming from a different source than the video server (104). The real-time data feeds from the video, stock and news servers are aggregated on the client (106) with enhanced speed because the feeds come directly to the client and not via the video server. The operating systems of the home server and remote servers utilize SCTP and specialized commands to implement the enhanced speed of real-time data aggregation being streamed to network clients without requiring modifications to existing client systems.

摘要： A computer implemented method, apparatus, and computer program product for transferring a privilege to a module. In one embodiment, a set of privileges required to initiate execution of code associated with the software module is identified to form enhanced privileges. The application is frozen. The enhanced privileges are unassigned to the application and the application has insufficient privileges to initiate execution of code associated with the software module. The software module is loaded into available application address space associated with the application. The enhanced privileges are transferred to the application. Execution of the application is unsuspended and the code associated with the software module is executed within the application.

摘要： The server side Transfer Control Protocol is modified so that the server returns a SYNACK message with the window size equal to zero if the server is busy. When a client sends a TCP connection request and receives a synchronization acknowledgement message with the window size equal to zero, the client knows that the server received the connection request and that the server is busy. The client may then send an acknowledgement message to complete the three-way synchronization handshake, thus successfully completing the connection. Thereafter, the client side TCP may probe the server side TCP until a window update message is received from the server. When the server sends a window update message to set the window size to a non-zero size, the client knows that the server is no longer busy and the client application may then use the TCP connection.

摘要翻译： 修改服务器端传输控制协议，以便服务器返回SYNACK消息，如果服务器正忙，则窗口大小等于零。 当客户端发送TCP连接请求并接收到窗口大小等于零的同步确认消息时，客户端知道服务器接收到连接请求，并且服务器正忙。 然后，客户端可以发送确认消息以完成三次同步握手，从而成功地完成连接。 此后，客户端TCP可以探测服务器端TCP，直到从服务器接收到窗口更新消息。 当服务器发送窗口更新消息以将窗口大小设置为非零大小时，客户端知道服务器不再忙，客户端应用程序可能会使用TCP连接。

摘要： A computer implemented method, apparatus, and computer program product for managing state data in a workload partitioned environment. Process state data for a process in a workload partition is saved. Process state data is used to restore the process to a given state. State data associated with open sockets and open files bound to the first process is saved. In response to a determination that the process is associated with a domain socket that is bound to a socket file, an absolute pathname for the socket file is saved. A domain socket associated with a connecting process in the workload partition uses the socket file to connect to a domain socket associated with a listening process in the same workload partition to enable the two processes to communicate with each other.

摘要： A system and method to manage device access in a software partition are provided. The illustrative embodiments provide a mechanism for exporting resources/devices from an administrator partition to a software partition in its purview. A trusted device list data structure is provided that identifies which devices are permitted to be exported into a software partition from an administrative partition. This trusted device list data structure also identifies which of the devices in the list of devices should be exported by default when exporting devices to a software partition, i.e. if no overrides are specified. In addition, a user-specifiable mechanism to override the entries in the trusted device list data structure is provided. For security purposes, this mechanism may not be used to export devices not listed in the trusted device list data structure. The mechanism may also be used to prevent the exporting of devices which are exported by default.

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 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.
