This disclosure describes techniques for determining whether network traffic contains one or more computer security threats. In order to determine whether a symbol stream conforms to the symbol pattern, a security device stores a full deterministic finite automaton (fDFA) that accepts streams of symbols that conform to the symbol pattern. The security device also creates a partial deterministic finite automaton (pDFA) that includes nodes that correspond to the nodes in the fDFA that have the highest visitation levels. The security device processes each symbol in the symbol stream using the pDFA until a symbol causes the pDFA to transition to a failure node or to an accepting node. If the symbol causes the pDFA to transition to the failure node, the security device processes the symbol and subsequent symbols in the symbol stream using the fDFA.

Systems and methods for virtualizing network intrusion detection system (IDS) functions based on each packet's source and/or destination host computer operating system (OS) type and characteristics are described. Virtualization is accomplished by fingerprinting each packet to determine the packet's target OS and then vetting each packet in a virtual IDS against a reduced set of threat signatures specific to the target OS. Each virtual IDS, whether operating on a separate computer or operating as a logically distinct process or separate thread running on a single computer processor, may also operate in parallel with other virtual IDS processes. IDS processing efficiency and speed are greatly increased by the fact that a much smaller subset of threat signature universe is used for each OS-specific packet threat vetting operation.

A method and systems for protecting the identification of a subscriber when a service provider transmits a subscriber request to a content provider in a distributed network environment, such as Internet. After the user sends a request to a service provider to which he has subscribed, the service provider encrypts the user identifier before transmitting this request with the encrypted user identifier to the content provider. Upon reception, the content provider uses an authentication Web Service supplied by the service provider for certifying the user identifier. If the user identifier is certified, the content provider transmits the requested content to the service provider, which formats it before sending it to the user. The content provider may charge the user through the service provider.

A content monitoring system applies policies to data transfers, and adapts the policies based on violations. Each policy includes a rule that detects violations and actions performed when the rule is violated. Policies may be adapted by, for example: enabling an inactive policy; modifying a parameter within a rule or an action; generating a new policy by combining a policy macro with the violating content block or with associated meta-data, for example, a user ID or IP address. An optional rolling buffer can be used to hold the most recent transfers, and newly adapted policies can be reapplied to the buffered content. Some content blocks are reassembled from a stream of terminal control protocol (TCP) packets that are transferred across a network barrier point. Other content blocks come from writes to removable media. Some content must be decoded, for example, a word processor file.

If a time variance is determined, the content of the program is redefined to include only its supposed content. The redefined content is then made part of an asset for later retrieval and distribution.

Multiple parallel passive threads of instructions coordinate access to shared resources using “active” semaphores. The semaphores are referred to as active because the semaphores send messages to execution and/or control circuitry to cause the state of a thread to change. A thread can be placed in an inactive state by a thread scheduler in response to an unresolved dependency, which can be indicated by a semaphore. A thread state variable corresponding to the dependency is used to indicate that the thread is in inactive mode. When the dependency is resolved a message is passed to control circuitry causing the dependency variable to be cleared. In response to the cleared dependency variable the thread is placed in an active state. Execution can proceed on the threads in the active state.

A lock-based software transactional memory (STM) implementation may determine whether a transaction's write-set is static (e.g., known in advance not to change). If so, and if the read-set is not static, the STM implementation may execute, or attempt to execute, the transaction as a semi-static transaction. A semi-static transaction may involve obtaining, possibly after incrementing, a reference version value against which to subsequently validate that memory locations, such as read-set locations, have not been modified concurrently with the semi-static transaction. The read-set locations may be validated while locks are held for the locations to be written (e.g., the write-set locations). After committing the modifications to the write-set locations and as part of releasing the locks, versioned write-locks associated with the write-set locations may be updated to reflect the previously obtained, or newly incremented, reference version value.

This invention provides an iterative process to maximum a posteriori (MAP) decoding. The iterative process uses an auxiliary function which is defined in terms of a complete data probability distribution. The auxiliary function is derived based on an expectation maximization (EM) algorithm.

A technique dynamically splits Traffic Engineering (TE) Label Switched Paths (LSPs) in a computer network. According to the novel technique, a head-end node may determine that a TE-LSP to a destination needs to be sized to a larger bandwidth (a “larger” TE-LSP) than currently available over a single path to the destination (e.g., a path that may also be required to meet other constraints, such as cost, delay, etc.). In response, the head-end node may dynamically “split” the larger TE-LSP, and create a first split TE-LSP over a best (e.g., shortest) available path (e.g., that meets other constraints). The first split TE-LSP may reserve a maximum available bandwidth for that best available path. The head-end node may then continue recursively creating subsequent split TE-LSPs for any remaining bandwidth of the larger TE-LSP over available paths until the larger TE-LSP may no longer be split (e.g., all bandwidth has been placed, configurable maximum number of splits reached, etc.). Notably, the split TE-LSPs may be “re-groomed” at a later time to recombine and reorganize the split TE-LSPs.

In one embodiment, the amount of wavelength converting material in the wavelength converting member is reduced, e.g., through laser ablation or etching, to produce the desired wavelength spectrum.
