Abstract: A computerized system and method for processing network content associated with multiple virtual domains. The processing may include anti-malware scanning and/or content filtering. The content associated with multiple domains may be processed in the same daemon process. In response to connection requests from virtual domains, the service process creates separate sockets to communicate with each virtual domain. A global configuration management module is used to provide configuration parameters for each session to the service process. A logging manager processes both the global logs and the logs from each virtual domain. Alternatively, the service process may initiate other service processes to handle incoming connections from one or more virtual domains, in order to better utilize resources in a multiple-CPU environment.

Abstract: Systems and methods for disrupting the operational capabilities and the distribution capabilities of computer viruses are provided. According to one embodiment, an execution environment is created that makes a computer system appear unique to incoming viruses. Responsive to installation of a valid program, the program is registered for execution by transforming it from an executable form into a locally unique form based on a diversity mechanism. Responsive to detecting an attempted execution of a program and prior to execution of the program, it is transformed by causing a protected pre-execution process of the computer system, which implements the diversity mechanism in the form of an inverse transform, to be applied. If the program was previously validly registered, then the transformation based on the diversity mechanism results in an executable program that will execute properly on the computer system; otherwise the transformation results in an executable program that will fail to correctly execute.

Abstract: Systems and methods for a multi-level advanced caching engine that is designed for processing a high-volume of transaction data and ensuring high performance query processing is provided. A folio is interactively updated on-demand for an organizational hierarchy with aggregated information from pre-summarized balances. Responsive to user-generated folio-level queries which depend upon balance values not currently stored within the financial transaction system, multiple instances of balances are dynamically created and populated with new balance values based on the user-generated folio-level query. Responsive to new transaction data, clean balance values are maintained within the dependent balances by regenerating the associated balance values.

Abstract: A mechanism is disclosed for enabling load balancing to be achieved in a network. In one implementation, load balancing is implemented on a “per flow” basis. At the time that a new flow starts, a path is selected. Packets associated with the flow are thereafter sent along that particular path. As the packets associated with the flow are forwarded along the particular path, a congestion metric is determined for the particular path as well as for a set of one or more other paths. Based at least partially upon the congestion metrics, a determination is made as to whether the flow should be moved. If so, then the flow is moved to an alternate path. By determining the congestion metrics for the multiple paths, and by moving the flow in response, it is possible to adapt to changing traffic conditions to keep the loads on the paths relatively balanced.

A second circuit combines a second derivative of the hard output with a derivative of the first combined signal to yield a second combined signal. A third circuit combines a derivative of the soft output with the second combined signal and a threshold value to yield a defect signal.

Abstract: Methods and apparatus are provided for managing multicast Internet Protocol (IP) flows. According to one embodiment, a multicast IP flow is identified at an interface of a network device using information from a packet header. For any newly identified multicast IP flow, if flow-specific services are required, a new first transmit control block (TCB), which includes one or more attributes relating to flow-specific services required by the newly identified multicast IP flow, is created for the newly identified multicast IP flow. Otherwise, if flow-specific services are not required by the newly identified multicast IP flow, a default second TCB, which excludes any attributes relating to flow-specific services and which includes one or more attributes related to a virtual interface (VI) serving as an outbound interface (OIF) for the newly identified multicast IP flow, is used.
