20080288572 | SCALABLE PRESENCE SERVER ARCHITECTURE - A presence server architecture includes a central presence information database to store presence information about a multiplicity of publishing entities, and at least two presence servers to separately access and update said presence information. The present invention also includes a presence server which includes a means to access a central database storing presence information segments about each user from multiple publishing entities over time, an aggregator to aggregate said presence information segments about one user into a current presence information document, and means to detect if another presence server has recently modified presence information document about the user. | 11-20-2008 |
20090133115 | VPN Management - A client attempts to transmit a presence state to a presence server that is behind a firewall of a secure network. If the client is inside the firewall, the presence server instructs resources within the secure network to directly communicate with the client. However, if the client is outside the firewall, then the client must tunnel into the secure network via a Virtual Private Network (VPN) before accessing the resources in the secure network. | 05-21-2009 |
20090172701 | MANAGING CONTACT LIST STATUS NOTIFICATIONS IN COLLABORATION SYSTEMS TO REDUCE NETWORK TRAFFIC - An awareness notification management system including a contact list manager managing an awareness service subscriber contact list including an active sublist for active contacts and an archive sublist for disabled contacts, and an awareness manager for monitoring the status contact list members, where the awareness manager is configured to access a history including at least one timestamp of a last communication exchange between the awareness service subscriber and any of the members of the contact list, and query the history for any of the timestamps and classify any of the contacts as a disabled contact on the archive sublist if the timestamp for the contact is older than a predefined age, and where the awareness manager is configured to forward to the awareness service subscriber awareness notifications regarding the status of the active contacts and withhold from the awareness service subscriber awareness notifications regarding the status of the disabled contacts. | 07-02-2009 |
20110161518 | ASYNCHRONOUS INVOCATION MECHANISM IN SESSION INITIATION PROTOCOL (SIP) SERVER CLUSTERS - Providing SIP application server interoperability, including detecting at a first SIP application server an event necessitating that work be performed in relation to a SIP application session that is managed by a second SIP application server, creating a SIP message object carrying a set of instructions representing the work, and sending the SIP message object for delivery to the second SIP application server and performance of the instructions at the second SIP application server in relation to the SIP application session. | 06-30-2011 |
20130304696 | ONLINE PROPAGATION OF DATA UPDATES - Various embodiments include a system for online propagation of data updates. The system can include: a computer system for storing a plurality of records; and a record update utility configured to: initiate a record update process for any of the records responsive to a modification of a trigger data item, wherein the process is performed while the system is online; create an update process timestamp indicating a time at which the record update process is begun; and determine if a last-modified timestamp associated with any of the records indicates an earlier time than the update process timestamp, and, if so: update the record to reflect the modification to the trigger data item, and modify the last-modified timestamp to reflect a time that is later than the update process timestamp. | 11-14-2013 |
