| 20120216266 | SYSTEM AND METHOD TO ASSOCIATE A PRIVATE USER IDENTITY WITH A PUBLIC USER IDENTITY - The inventive system includes a host, a network including a security gateway, and a public application. Established are an access session between the network and the host and an application session between the public application and the network. An application session record is created for the application session, and includes the user's public user identity used to access the public application, the user's private user identity used to access the network, a host identity, and an application session time. To determine the private user identity for the application session, the security gateway sends a query with the host identity and the application session time. These are compared with the host identity and access session time in an access session record. If they match, then the private user identity in the access session record is returned, and it is stored as the private user identity in the application session record. | 08-23-2012 |
| 20120204236 | Systems and Methods for User Access Authentication Based on Network Access Point - Systems and methods of authenticating user access based on an access point to a secure data network include a secure data network having a plurality of a network access points serving as entry points for a user to access the secure data network using a user device. The user is associated with a user identity, each network access point with a network access point identity. The user uses a user device to send an access request, requesting access to the secure data network, to the network access point, which then sends an authentication request to an identity server. The identity server processes the authentication request, by validating the combination of the user identity and the network access point identity, and responds with an authentication response, granting or denying access, as communicated to the user device via an access response. | 08-09-2012 |
| 20120179770 | VIRTUAL APPLICATION DELIVERY CHASSIS SYSTEM - 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. | 07-12-2012 |
| 20120144015 | System and Method for Distributing Application Traffic to Servers Based on Dynamic Service Response Time - A service gateway processes a service request received from a host by: relaying the service request from the service gateway to a server over a service session between the service gateway and the server; determining a service request time for the service session; receiving by the service gateway a service response from the server; determining by the service gateway a service response time; calculating by the service gateway a service processing time for the service request from the service request time and the service response time; comparing the service processing time with an expected service processing time; and updating a server busy indicator for the server in response to the comparing. If the service processing time exceeds the expected service processing time, the server busy indicator is updated to indicate that the server is busy. Otherwise, the server busy indicator is updated to indicate that the server is not busy. | 06-07-2012 |
| 20120084419 | SYSTEM AND METHOD TO BALANCE SERVERS BASED ON SERVER LOAD STATUS - A method, system, and computer program product for balancing servers based on server load status, include: receiving from a server a service response to a service request, the service response including a result from a processing of the service request and a server status indicating a computing load status of the server; obtaining the server status from the service response; receiving a next service request from a host, the next service request comprising a Uniform Resource Locator (URL); determining that the server is configured to process the URL; determining whether the server status indicates that the server is available to process the next service request; and in response to determining that the server status indicates that the server is available to process the next service request, sending the next service request to the server. | 04-05-2012 |
| 20110239289 | System and Method to Associate a Private User Identity with a Public User Identity - The inventive system includes a host, a network including a security gateway, and a public application.
