Filed:

May 26, 2006

Appl. No.:

11/420582

Inventors:

David Horton - Sharon MA, US
David Duda - Holliston MA, US

International Classification:

G06F 11/00

US Classification:

714004000

Abstract:

Systems and method for providing application layer fault tolerance in a VoIP architecture is shown and described. The method includes associating a virtual network address with one of a first communication device and second communication device, receiving a message from a network element, detecting a fault on an active one of the communication devices, and associating the virtual address with the other of the communication devices. Each of the first and second communication devices is coupled to a VoIP network. The virtual network address is associated with the active one of the communication devices. The detection of the fault occurs when the active communication device is at a first execution point of an application executing on the active communication device. When the virtual address is associated with the other communication device, the other of communication devices continues to provide the service from the first execution point.

US Classification:

714004000

Abstract:

Systems and methods for providing redundant application servers are described. A method of providing application server redundancy in a VoIP environment includes, receiving, at a standby server, application layer and signaling layer state information related to an active server and configuring the standby server to have substantially the same application layer and signaling layer state as the active server. The method also includes receiving, at the standby server, a copy of a message received by the active server and processing, by the standby server, the copy of the message to maintain synchronization between the state of the active server and the standby server.

International Classification:

G06F 11/00

US Classification:

714004000

Abstract:

Systems and methods for messaging handling among redundant application servers are described. A method of providing application synchronization among a plurality of servers in an VoIP network environment includes pausing execution of an application on a standby server when the standby server encounters a checkpoint in the application and receiving a first message indicating that an active server reached the same checkpoint in a copy of the application executing on the active server. The method also includes transmitting, from the standby server, a second message to the active server indicating that the standby server received the first message and resuming execution of the application on the standby server.

US Classification:

705 2

Abstract:

Systems, methods, and computer program product for ensuring compliance by an employee to requirements of an employer includes storing a profile of each employee in a database. The profile of each employee includes information about one or more contractual relationships related to a practice of that employee. A first online portal is provided to each employee with a profile in the database. The first online portal presented to each employee has a user interface customized for that employee through which that employee dynamically manages the information in the profile of that employee. An employer of one or more of the employees with a profile stored in the database accesses the dynamically managed information in each profile of that one or more employees through a second online portal. One or more rules are automatically applied to the information accessed by the employer to determine whether the one or more employees are in compliance with requirements of the employer.

Abstract:

Systems, methods, and computer program product for verifying financial exchanges made by an organization to a professional include obtaining, from a third-party database, payment information related to payments purportedly made by one or more organizations to a professional, automatically comparing the payment information obtained from the third-party database related to the payments purportedly made by one or more organizations to the professional with payment information entered by the professional through an online portal into a second database, and displaying, to an authorized viewer, results of the comparison of the payment information entered by the professional into the second database with the payment information obtained from the third-party database, to facilitate identifying discrepancies therebetween.
