Provided are methods and systems for transition between a current cloud-based code environment and an updated cloud-based code environment. A method for transition between a current cloud-based code environment and an updated cloud-based code may commence with generating a steering policy. The steering policy may include a set of rules to guide steering decisions between a current cloud-based code environment and an updated cloud-based code environment. The method may further include sending the steering policy to a steering server. The steering server may make steering decisions to steer, based on the steering policy, service requests between the current cloud-based code environment and the updated cloud-based code environment. The method may continue with receiving feedback concerning actual steering decisions made by the steering server. The method may further include automatically adjusting the steering policy in response to the feedback.

Policy-driven management of application traffic for providing services to cloud-based applications

Policy-driven management of application traffic is provided for services to cloud-based applications. A steering policy refers to a set of rules is generated for a deployment from a current code environment to one or more replicated code environment differing in some key respect. The steering policy can guide steering decisions between the current and updated code environments. A steering server uses the steering policy to make decisions about whether to send service requests to the current code environment or the updated code environment. Feedback concerning actual steering decisions made by the steering server is received (e.g., performance metrics). The steering policy is automatically adjusted in response to the feedback.

A structural matching engine for non-deterministic filtering operations is provided. The structural matching engine includes an active node processor (ANP) configured to process a state of an active list to determine possible future states of a non-deterministic finite automaton (NFA). The ANP processes the state according to rules. The structural matching engine includes an active list processor (ALP) configured to initiate a lookup for a token value corresponding to the state of the active list. The ALP provides a next sate of the active list to the ANP for processing according to the rules upon completion of the processing of the state by the ANP, wherein the possible future states of the NFA are linked by the ALP to form a target list, the target list stacked on top of the active list in a data structure. A processor and a method for filtering data associated with non-deterministic states are also included.

Method and system for non-deterministic finite automaton filtering

A method for evaluating contents of a message is provided. The method initiates with characterizing a message segment. Then, the message is scanned to define tokens associated with the message segment. Next, the tokens are parsed to define substructures. Then, the rules associated with the tokens are determined, wherein the rules define actions. At the same time determining the session or meta session associated with the communication. Then, the actions associated with the message are executed. Next, the message is queued to be sent out. A method for providing content based security, a computer readable media, an adapter card and a network device configured to provide content based security and an intrusion protection system are provided.

Method and apparatus for semantic processing engine

A processor configured to identify message contents is provided. The processor includes a message characterization block configured to characterize a message through analysis of header information associated with the message. A semantic processing block configured to translate the message into tokens associated with segments of the message is included. The semantic processing block identifies rules associated with each of the tokens and the semantic processing block is configured to apply the identified rules to the message. A queuing block configured to queue the message to be transmitted from the processor is included. A method for providing content based security, a computer readable media, an adapter card and a network device configured to provide content based security and an intrusion protection system are provided.

Semantic processing engine

Disclosed is a media access controller for transferring data along a computer network. The media access controller includes a transmit media access controller that is configured to process out-going packet data received from an upper layer for transmission to a lower layer. A receive media access controller that is configured to process in-coming packet data received from the lower layer for transmission to the upper layer. A transmit multi-packet queue FIFO for receiving the out-going packet data from the upper layer before being passed to the transmit media access controller. A receive multi-packet queue FIFO for receiving the in-coming packet data that is received by the receive media access controller. The media access controller further including a media access controller manager interfacing with the transmit and receive media access controllers. The media access controller manager being responsible for managing the flow of packet data through the transmit and receive multi-packet queue FIFOs.
