摘要： A method, system, and computer program product in a computer-readable medium for delivering data, received from a network, to a storage buffer assigned to an application is proposed. An application designates a communication buffer within a local data processing system for buffering data communicated with an application. The local data processing system reports to a network interface of the local data processing system a memory address of the designated communication buffer, and the data processing system creates a cookie containing the memory address. The data processing system then sends the cookie form the local data processing system to a remote data processing system, such that the remote data processing system may address data directly to the designated communication buffer.

摘要： A system, apparatus and method of improving network data traffic between interconnected high-speed switches are provided. As is well known, when a packet of data is longer than a path maximum transmission unit (PMTU), the packet will be fragmented. In the case of the invention, the packet is fragmented by a transmitting router connected to a high-speed switch. When a receiving router, which is also connected to an high-speed switch, begins to receive the fragments, it will check to see whether its sub-network may handle data of a substantially longer length than the length of the fragments. If so, the receiving router will collect the fragments, reassemble them into the original packet and transmit the reassembled packet to its destination.

摘要： Methods, systems, and media to sub-divide an ephemeral port range and allocate ports from the sub-divided ephemeral port ranges to facilitate communication with another destination, or target, application are contemplated. Embodiments involve a client computer system having one or more source applications. Embodiments also include hardware and/or software for categorizing transactions based upon characteristics of the transactions. Such categories correspond to categories with which sub-divisions of ephemeral port numbers are assigned. After a transaction is associated with a category, a port number selected from a pool of available port numbers in a sub-division of ephemeral port numbers assigned to that category. In many embodiments, an initial configuration is implemented via a configuration file at the startup of the client computer system. In further embodiments, assignments of ephemeral port numbers to the categories of transactions are dynamically adjusted based upon, e.g., actual usage of the port numbers.

摘要： A method, computer program product, and a data processing system for processing transactions of a client-server application is provided. A first data set is transmitted from a client to a server. A second data set to be transmitted to the server is received by the client. An evaluation is made to determine whether transmission of the second data set is blocked until receipt of an acknowledgment of the first data set. A number of allowable outstanding acknowledgements is increased responsive to determining that the second data set is blocked from transmission.

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 mutli-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 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： 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.
