摘要： Systems and methods provide a selective instrumentation strategy for monitoring the progress of transactions in a distributed computing system. The monitoring of the transactive processing of jobs is considered through a collection of computer operating stages in a distributed system, using limited information. The monitoring is performed by observing log records (or footprints) produced during each stage of processing in the system. The footprints lack unique transaction identifiers resulting in uncertainties in monitoring transaction instances. The processing stages are selective instrumented to reduce monitoring uncertainty under the given constraints such as limited budget for instrumentation cost.

摘要： A method for measuring trust in a transaction over a public key certificate network includes associating each edge KA→KB of an public key certificate network connecting two public keys KA and KB with a probability p that information about KB is reliable, and a confidence c that is a total dollar amount of transactions which have involved using edge KA→KB. One or more authentication paths are formed in the public key certificate network starting from public key KS and ending with a target public key KT. A limit l of an amount of insurance that an owner of KS is willing to provide to a user interested in a transaction with an owner of KT is calculated, and for each amount m

摘要： Orthogonal Frequency Division Multiplexing (OFDM) is combined with a plurality of transmitting antennas to yield a system that provides space, frequency and time diversity. Specifically, an arrangement is created where a transmitter includes a plurality of antennas that are transmitting simultaneously over the same frequency subbands, and the symbols that are transmitted over each subband, in any given time slot, over the different antennas are encoded to provide diversity. The principles of trellis coding, space-time coding, or any other diversity-producing coding can be applied in this arrangement.

摘要： Methods and apparatus are provided for recovering from packet loss in an end-to-end network connection having at least one wireless segment. A packet on a wireless segment of an end-to-end network connection is processed by determining whether the packet comprises one or more of a lost packet and a malformed packet; and generating a modified packet for an application associated with the packet to replace one or more of the lost packet and the malformed packet if the application is substantially tolerant to one or more of lost and malformed data. The modified packet comprises, for example, a non-original packet and/or a corrected packet. Link layer information or information from a deep packet inspection can be used to determine whether the packet comprises a lost packet or a malformed packet.

摘要： Middlebox systems that can enter a connection include a monitoring module to monitor information in a connection between a client and a server, a processor to determine that the connection is idle, a table configured to create a first entry for the client and a second entry for the server, where the entries are initialized using information gathered by the monitoring module, and a control module to redirect the connection between the client and server to the middlebox. Middlebox systems that can exit a connection include a processor to determine a mismatch between sequence numbers in a first connection to a client device and in a second connection to a server device. A network control module delays acknowledgment signals from the middlebox on a connection to decrease the degree of mismatch and establishes a direct connection between the client device and the server device when mismatch is zero.
