摘要： A dynamically-enforceable application-controlled quasi-reliable extension to TCP permits a client application to dynamically set a percent loss tolerance for data transmission reliability through network input/output system calls to the TCP, thereby programming the transport layer to optimistically acknowledge non-critical missing frames. The reliability requirement can be dynamically set within TCP to the level of reliability required for specific data frames within the data stream during the data transfer. Based on this loss tolerance specified, the TCP layer makes a determination whether to trigger a retransmission or continue delivering out-of-order frames to the application. A forced acknowledgement frame is sent for each missing packet until the number missing packets causing forced acknowledgments within the current receive buffer frame exceeds the loss tolerance. This process avoids needless retransmissions and permits the TCP data flow and sliding window to advance uninterrupted, thereby providing substantial performance benefits to network throughput.
摘要翻译：对TCP的动态可执行的应用程序控制的准可靠扩展允许客户端应用程序通过网络输入/输出系统调用TCP动态设置数据传输可靠性的百分比损耗容限，从而编程传输层，以乐观地确认非关键丢失帧。可靠性要求可以在TCP内动态设置为在数据传输期间数据流内特定数据帧所需的可靠性水平。基于指定的丢失容限，TCP层确定是否触发重传，或者继续向应用发送无序帧。为每个丢失的数据包发送强制确认帧，直到导致当前接收缓冲区帧内的强制确认的数据丢失数据包超过丢失容限。该过程避免了不必要的重传，并允许TCP数据流和滑动窗口不间断地前进，从而为网络吞吐量提供显着的性能优势。

摘要： Disclosed is a computer implemented method and apparatus to retrieve authentication records required for user validation and creation of authentication credentials from an authentication sever to be passed to the user. The method is comprised of the authentication server storing a first authentication record, then generating a first authentication credential based on the first authentication record. The authentication server associates the first authentication record with a first credential expiration time. The authentication server stores a second authentication record. The authentication server generates a second authentication credential based on the second authentication record, wherein the second authentication credential is associated with a second credential expiration time. Next, the authentication server associates the second authentication credential with a second credential expiration time. The authentication server determines that the first credential expiration time is earlier than the second credential expiration time and caches the first authentication record to cache.

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.

摘要： A method, system, and program for monitoring thread usage to dynamically control a thread pool are provided. An application running on the server system invokes a listener thread on a listener socket for receiving client requests at the server system and passing the client requests to one of multiple threads waiting in a thread pool. Additionally, the application sends an ioctl call in blocking mode on the listener thread. A TCP layer within the server system detects the listener thread in blocking mode and monitors a thread count of at least one of a number of incoming requests waiting to be processed and a number of said plurality of threads remaining idle in the thread pool over a sample period. Once the TCP layer detects a thread usage event, the ioctl call is returned indicating the thread usage event with the thread count, such that a number of threads in the thread pool may be dynamically adjusted to handle the thread count.

摘要： A method for processing data packets in an interception proxy server without using a Network Address Translation module. A TCP packet received at a router is encapsulated using generic routing encapsulation (GRE). The TCP packet is redirected to a proxy server through a GRE tunnel which includes a redirection rule comprising a local destination IP address and port to be used for traffic passed through the tunnel. When the proxy server receives the TCP packet, the TCP packet is decapsulated. If a flag is set in the payload header of the TCP packet indicating that a redirection rule has been configured for traffic passed through the tunnel, the payload header of the TCP packet is modified according to the redirection rule. The modified TCP packet is then passed to a transmission control protocol of the proxy server.

摘要： A method for virtual segmentation off-load in a logically partitioned data processing system is provided. A data transmission protocol stack formats a data message for segmentation off-load to form a virtual segmentation off-load package. The size of the data message is larger than a size of a maximum transmission unit. A partition manager firmware copies the virtual segmentation off-load package from a first logical partition to a virtual Ethernet adapter associated with a second logical partition. The virtual segmentation off-load package is copied without performing a segmentation operation on the data message associated with the virtual segmentation off-load package.

摘要： A method, computer program product, and data processing system for efficiently discovering and storing path MTU information in a sending host are disclosed. In a preferred embodiment, two path MTU tables are maintained. One path MTU table contains MTU values corresponding to the first-hop routers associated with the sending host. The other path MTU table contains MTU values corresponding to individual destination hosts. When the sending host needs to send information to a destination, it first consults the MTU table associated with individual destination hosts. If an entry for that destination host is found in the table, the sending host uses that MTU value. If not, the sending host consults the MTU table for the first-hop router on the path to the destination host and uses that MTU value. If that MTU value is too high, a new entry is made in the host-specific MTU table for the destination host.
