In order to transparently redirect an HTTP connection request that is directed to an origin server ( ) to a proxy cache ( - ), a proxy redirector ( ) translates the destination address of packets directed to the origin server to the address of the proxy. During a handshaking procedure, a TCP connection is transparently established between the client ( - ) and the proxy cache. When the client transmits a GET request to what it thinks is the origin server, which request specifies the complete address of an object at that origin server that it wants a copy of, the proxy redirector modifies the complete address specified in that GET request before it is sent to the proxy cache. Specifically, the IP address of the origin server found in the destination field in the IP header of the one or more packets from the client containing the GET request is added by the proxy redirector as a prefix to the complete URL in the GET request to form an absolute URL. The proxy cache determines from that absolute URL whether it has the requested object stored in its cache. If it does, it sends the object back to the proxy redirector, which masquerades those packets as coming from the origin server by translating their destination address to the address of the client and their source address to that of the origin server.

A fault monitoring, performance monitoring and fault tolerance apparatus and method for target target application programs is realized in an application supervisor by employing a supervisor agent, modified application programming interfaces (APIs), a generic application wrapper and a shell script that operate interactively to detect and automatically resolve reliability and performance problems occurring in executing the target application program. This is realized, in accordance with the invention, without the need to access, modify or have knowledge of the source code of the target application program to be supervised. In a specific embodiment of the invention, Javaâ programming language target application programs are supervised. This is realized by employing the supervisor agent that attaches to a Java virtual machine through two virtual machine native interfaces. One interface is the Java Virtual Machine Profiler Interface (JVMPI) and the other is the Java Native Interface (JNI).

A method and apparatus for a fault injection tool having greater flexibility, ease and portability in realizing the basic functionality of the fault injection. The basic functionality of the fault injection process is abstracted into three base classes, namely, a fault injector (FI), a workload generator (WG) and a data collector (DC). A control class performs configuration and management of the objects that are instantiated from the base classes. The control class also implements a graphical user interface. For each base class there is a corresponding core class that performs control and management of a so-called associated âpluginâ. Each of the core classes can be implemented as a single class or as a pair of distributed classes. If a core class is implemented as a pair, the FI, WG, or DC object controls operation of the FIRemote, WGRemote or DCRemote object, respectively. For each core class, the associated plugin performs the actual functionality.

Solid blends of rubbery polymers and amorphous or crystalline polymers, said blends being free-flowing at temperatures lower than the glass transition temperature or crystalline melting temperature of the amorphous or crystalline polymer, are prepared by intimate mixing procedures. In general, said mixing conditions include high shear conditions sufficient to convert polymer A to dispersed particles coated with polymer B and produce a free-flowing powder blend.

Fault tolerance is improved in a computing system which includes one or more computing machines by (i) executing a control thread or other control program in conjunction with a fault tolerance software system running on at least one of the machines, and (ii) initiating via the control program a test script program which sends one or more requests to a monitored program. The test script program also processes corresponding responses to the one or more requests, and generates a return value utilizable by the control program to indicate a failure condition in the monitored program. The computing system may be configured in accordance with a client-server architecture, with the fault tolerance software system and the monitored program both running on a server of the system. The test script program is preferably implemented in an object-oriented programming language such as Java, such that one or more components of the test script program comprise a base class from which one or more other components of the test script program are generatable for use with the monitored program.

A method and apparatus for executing target application programs with employment of a supervisor that is coupled to the executing target application through a conventional status reporting port of the computer. Events that represent execution errors or unexpected behavior are provided to the reporting port, or discovered through the reporting port, and the supervisor responds to such events by perusing a configuration that is tailored to the executing target application. For each reported event, the supervisor retrieves one or more actions that the configuration file specifies for the reported events and executes the specified actions. The configuration file includes actions that aim to effect a recovery, from reported events, including restart application, or a thread of the application, based on checkpointed data, restart target application as soon as it becomes idle, and suspend a thread when a thread starvation condition exists.

A method for Real-time Transport Protocol (RTP) packet authentication on a packet data network. In particular, the invention relates to a method for preventing toll fraud, privacy compromise, voice quality degradation, or denial of service (DoS) on Voice over IP networks. The Real-time Transport Protocol (RTP) is susceptible to several security attacks, including thirdparty snooping of private conversations, injection of forged content, and introduction or modification of packets to degrade voice quality. The Secure Real-time Transport Protocol (SRTP) provides confidentiality, message authentication, and replay protection for RTP traffic. However, SRTP incurs an additional overhead to verify the HMAC-SHA1 message authentication code for each packet. SRTP+ significantly decrease the verification overhead compared to SRTP and thereby increases the number of faked packets required to mount a successful denial of service attack. SRTP+ provides packet authentication but not integrity.
