Expertise, for performing classification of a type of network traffic, can be encapsulated in a module. A set of modules, as currently available to a traffic controller, can be referred to as a collection. Programming language constructs are introduced that facilitate the writing of modules customized to identify network traffic that is peculiar to a particular user, or to a relatively small group of users. An example programming language, based on Tcl, is introduced. A key aspect is event-driven programming, and the 'when' command construct is introduced. Three important event types, that can trigger a 'when' command, are CLIENT_DATA, SERVER_DATA, and RULE_INIT. Another key aspect is an ability to keep state information between events. Constructs for intra-session, intra-module, and global state are introduced. A module can be blocked from executing more than once for a session. Successful execution of a module can be specified by a &#x201c;match&#x201d; statement.

System and method for customizing the identification of application or content type

A method for electing a master blade in a virtual application distribution chassis (VADC), includes: sending by each blade a VADC message to each of the other blades; determining by each blade that the VADC message was not received from the master blade within a predetermined period of time; in response, sending a master claim message including a blade priority by each blade to the other blades; determining by each blade whether any of the blade priorities obtained from the received master claim messages is higher than the blade priority of the receiving blade; in response to determining that none of the blade priorities obtained is higher, setting a status of a given receiving blade to a new master blade; and sending by the given receiving blade a second VADC message to the other blades indicating the status of the new master blade of the given receiving blade.

Virtual application delivery chassis system

Applying a security policy to an application session, includes recognizing the application session between a network and an application via a security gateway, determining by the security gateway a user identity of the application session using information about the application session, obtaining by the security gateway the security policy comprising network parameters mapped to the user identity, and applying the security policy to the application session by the security gateway. The user identity may be a network user identity or an application user identity recognized from packets of the application session. The security policy may comprise a network traffic policy mapped and/or a document access policy mapped to the user identity, where the network traffic policy is applied to the application session. The security gateway may further generate a security report concerning the application of the security policy to the application session.

Applying security policy to an application session

Methods and systems for synchronization of configuration files of a plurality of blades in a virtual application distribution chassis are disclosed. In an exemplary method, a master blade processes a configuration command, updates a first configuration file with the configuration command and generates an updated tag, and sends a configuration message to at least one slave blade of the virtual application distribution chassis informing of the updated configuration file. The configuration message is received by a given slave blade of the one or more slave blades and compared with a second configuration file stored at the given slave blade; and in response to determining that the updated tag in the configuration message is more recent than the tag in the second configuration file stored at the given slave blade, the slave blade sends a request for the updated configuration file to the master blade.

Synchronization of configuration file of virtual application distribution chassis

Provided are methods and systems for allocating resources in a multi-core computing environment. The method comprises selecting, by one or more processors, at least one dedicated core for execution of a resource allocation algorithm. After selection of the dedicated core, the dedicated core allocates, based on the resource allocation algorithm, a network resource to a client. Furthermore, the dedicated core assigns the network resource to network packets associated with the client for processing by data cores. After the assigning of the network resource, the data cores process the network packets according to the allocated network resource.

Allocating resources in multi-core computing environments

Embodiments of the present technology relate to a method for applying a security policy to an application session, comprising: determining, by a security gateway, a first user identity and a second user identity from a data packet for an application session; obtaining, by the security gateway, a security policy for the application session; and applying the security policy to the application session by the security gateway. The user identity may be a network user identity or an application user identity recognized from packets of the application session. The security policy may comprise a network traffic policy mapped and/or a document access policy mapped to the user identity, where the network traffic policy is applied to the application session. The security gateway may further generate a security report concerning the application of the security policy to the application session.

Expertise, for performing classification of a type of network traffic, can be encapsulated in a module. A set of modules, as currently available to a traffic controller, can be referred to as a collection. An improved process, for updating a collection of modules, is presented. A traffic controller can have two or more locations, each storing a module collection. While an old collection remains active, a new collection can be loaded. Once the new collection is loaded, transitioning can be undertaken, on a session-by-session basis that keeps a traffic controller active, from the old collection to the new collection.

System and method of updating modules for application or content identification

Applying a security policy to an application session, includes: recognizing the application session between a network and an application via a security gateway; determining by the security gateway a user identity of the application session using information about the application session; obtaining by the security gateway the security policy comprising network parameters mapped to the user identity; and applying the security policy to the application session by the security gateway. The user identity may be a network user identity or an application user identity recognized from packets of the application session. The security policy may comprise a network traffic policy mapped and/or a document access policy mapped to the user identity, where the network traffic policy is applied to the application session. The security gateway may further generate a security report concerning the application of the security policy to the application session.

A security gateway includes packet routing policies, each including a host network address, an application network address, and a forwarding interface. In routing data packets of an application session, the security gateway: recognizes the application session between a network and an application; determines a user identity from an application session record for the application session; determines packet routing policies applicable to the application session based on the user identity; receives a data packet for the application session, including a source network address and a destination network address; compares the source network address with the host network address, and the destination network address with the application network address; and in response to finding a match between the source network address and the host network address, and between the destination network address and the application network address, processes the data packet using the forwarding interface of the packet routing policy.
