Network session traffic behavior learning system

Provided are methods and systems for a Transmission Control Protocol (TCP) state handoff of a data traffic flow. A method for a TCP state handoff of a data traffic flow comprises determining a TCP state at predetermined times by a state machine unit. The TCP state includes data concerning a session between a client and a server. The TCP state for the predetermined times is stored to a database. A request to apply a predetermined policy to the session is received by a transaction processing unit and, in response to the request, a session request associated with the session between the client and the server is sent to an access control unit. The session request is processed by the access control unit based on the TCP state and according to the predetermined policy.

Transmission control of protocol state exchange for dynamic stateful service insertion

Exemplary embodiments for configuring a network device using user-defined scripts are disclosed. The systems and methods provide for a servicing node to receive a request for a network session between a client device and a server, receive a user defined class and a user defined object configuration from a node controller, and use the information to instruct an object virtual machine to generate at least one user defined object. The servicing node can then apply the at least one user defined object to a data packet of the network session, where the user defined object allows a user to configure the network device with user-defined instruction scripts.

Programming a data network device using user defined scripts

Provided are methods and systems for dynamically distributing a service session from a client device. The method may commence with receiving a packet associated with the service session from the client device by a gateway node. The method may include determining that the packet matches a service address in a forwarding policy. The method may continue with selecting one of a plurality of forwarding nodes for sending the packet to the one of the plurality of forwarding nodes. The method may include receiving the packet of the service session by the one of the plurality of forwarding nodes. The method may continue with determining that the packet matches the service address serviced by a servicing node of a plurality of servicing nodes. The method may further include sending the packet to the servicing node for forwarding the packet to a server by the servicing node.

Distributing service sessions

Methods and systems are provided for automatically capturing network data for a detected anomaly. In some examples, a network node establishes a baseline usage by applying at least one baselining rule to network traffic to generate baseline statistics, detects an anomaly usage by applying at least one anomaly rule to network traffic and generating an anomaly event, and captures network data according to an anomaly event by triggering at least one capturing rule to be applied to network traffic when an associated anomaly event is generated.

Automatic capture of network data for a detected anomaly

Provided are methods and systems for configuring a network device with user-defined instruction scripts. The method may commence with receiving a request for a network session between a client device and a server. The method may further include receiving a user-defined class and a user-defined object configuration. The user-defined class and the user-defined object configuration may include the user-defined instruction scripts provided by a user of the client device. The method may further include instructing an object virtual machine to generate at least one user-defined object based on the user-defined class and the user-defined object configuration. The method may continue with instructing an object virtual machine to generate at least one user-defined object based on the user-defined class and the user-defined object configuration.

Provided are methods and systems for eliminating a redirection of data traffic in a cluster. An example method may include receiving, by one or more nodes of the cluster, a data packet associated with a service session. The method may include determining, by the node, that the data packet is directed to a further node in the cluster. The method may further include, in response to the determination, acquiring, by the node, a session context associated with the service session. Acquiring the session context may include sending, by the node, a request for the session context to the further node and receiving the session context from the further node. The method may further include processing, by the one or more nodes, the data packet based on the session context.

Eliminating data traffic redirection in scalable clusters

Exemplary embodiments for a distributed system for determining a server's health are disclosed. The systems and methods provide for a network controller to direct one or more servicing nodes to check the health of one or more servers, and report a health score to the network controller. The network controller may then calculate, update and maintain a health score for each server in the network from the various health scores reported to it from the servicing nodes. This allows a distributed system to be used to facilitate network operations, as a single device is not relied on for periodically determining each server's health.
