Patent number: 8447808Abstract: Techniques are disclosed for generating and managing presentities in accordance with a virtual presence server. By way of example, a method for requesting information from at least one server comprises the following steps. A client request, which expresses a request that can not be satisfied by a single existing presentity, is obtained at an intermediate server, wherein the intermediate server operates as a virtual presence server. The virtual presence server (i.e., intermediate server) creates a set of software objects for a virtual presentity, the set of objects embodying logic to combine presence information from one or more of existing presentities and external information sources, in accordance with at least one existing presence server. The virtual presence server creates an association between the request of the client and the created virtual presentity that allows the presence information to be propagated back to the client.Type: GrantFiled: September 19, 2008Date of Patent: May 21, 2013Assignee: International Business Machines CorporationInventors: Arup Acharya, Nilanjan Banerjee, Dipanjan Chakraborty, Koustuv Dasgupta, Archan Misra, Xiping Wang, Charles P.

Patent number: 8285779Abstract: Techniques for supporting a presence virtualization query are provided. The techniques include receiving a virtual query from a client, the virtual query specified in terms of a membership set of members, wherein the membership set comprises a list of presentity uniform resource identifiers (URIs) and a separate transformation function, defined over a set of presence documents of the members in the membership set, redirecting the query to a destination virtual presentity URI whose presence state comprises an aggregation of the presence documents of the list of URIs in the membership set and a corresponding query element (QE) object that manages subscriptions for the URI, adding the client as a watcher for the destination virtual presentity URI, and applying transformation logic specified by the watcher client and notifying a corresponding client of a resulting output.Type: GrantFiled: February 8, 2010Date of Patent: October 9, 2012Assignee: International Business Machines CorporationInventors: Arup Acharya, Nilanjan Banerjee, Dipanjan Chakraborty, Koustuv Dasgupta, Archan Misra, Xiping Wang, Charles P.

Patent number: 8230082Abstract: A technique for use in a client, wherein the client supports a state-based signaling protocol (e.g., Session Initiation Protocol or SIP), includes initiating a given session state between the client and a server that also supports the state-based signaling protocol, and refreshing the given session state in a randomized manner. Further, a technique for use in a server, wherein the server supports a state-based signaling protocol (again, e.g., SIP), includes randomly assigning an expiration time duration for a given session state between the server and a client that also supports the state-based signaling protocol, and reporting the randomly assigned expiration time for the given session state to the client. By randomizing various behaviors of the client, the server, or both, bursty traffic in the communication network is reduced or eliminated.Type: GrantFiled: January 25, 2011Date of Patent: July 24, 2012Assignee: International Business Machines CorporationInventors: Gary John DeVal, Curtis Eldon Hrischuk, Erich Miles Nahum, John Michael Tracey, Xiping Wang, Charles P.
