Patent number: 9596063Abstract: A primary call admission controller (CAC) system receives a request from a client to allocate a network resource such as a network bandwidth. The primary CAC system may determine subordinate CAC to delegate the allocation and transfer the request to the subordinate CAC. Subsequently, the subordinate CAC analyzes the communication session attributes to determine an available network resource for the communication session. Upon a positive determination, the subordinate CAC allocates the network resource and signals the allocation up the network chain to the primary CAC and the client.Type: GrantFiled: April 18, 2014Date of Patent: March 14, 2017Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Pascal Menezes, Wajih Yahyaoui, Kapil Sharma, Warren Barkley

Detecting quality of service for unified communication and collaboration (UC and C) on internetworks
Patent number: 9413792Abstract: QoS support is detected during discovery of potential media paths between a source and a destination by examining the markings of each available media path and selecting a more suitable media candidate based on a set of QoS prioritization rules. Optionally, each endpoint may update a UC&C monitoring service with the QoS results of the candidate list discovery process so that any automated diagnostic and auditing systems can be alerted to any misconfigured Network Elements.Type: GrantFiled: November 9, 2012Date of Patent: August 9, 2016Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Pascal Menezes, Wajih Yahyaoui, Warren Barkley -
Patent number: 9230033Abstract: Concepts and technologies are described herein for processing queries from a user's computing device initiating a query. In one embodiment, responding to the query involves searching for results based on the user's location and a list of federated enterprises. A clearinghouse server receives the query and determine a location of the user by accessing a location information database. The clearinghouse server then uses the location information in formulating a query to a search engine, by including location information with the user's query. The results are then processed in light of the list of federated enterprises. The processing may include ordering the search results, filtering the search results, or allowing enhanced forms of communications between the user and a selected party associated with the federated enterprise. The results are provided to the user. The enhanced forms of communication include instant messaging and video conferencing.Type: GrantFiled: September 6, 2011Date of Patent: January 5, 2016Assignee: Microsoft Technology Licensing, LLCInventors: Wajih Yahyaoui, Warren Vincent Barkley, Kapil Nath Sharma, Joseph Arthur Williams

Patent number: 9106513Abstract: Unified Communication and Collaboration (UC&C) systems are enabled to dynamically enlighten a set of network elements (NEs) and/or network infrastructure with application awareness so that an accurate set of rules or actions can be applied for a given session without needing to lookup the payload of every packet or applying a somewhat ineffective expensive heuristic mechanisms. Taking advantage of typically longer communication session durations and separate control and media planes, a UC&C control point programs a set of NEs for a given UC&C media flow within a scalable and timely manner. Quality of Service (QoS), security, monitoring, and similar functionality may also be programmed into the NEs through the UC&C control point.Type: GrantFiled: March 23, 2012Date of Patent: August 11, 2015Assignee: Microsoft Technology Licensing, LLCInventors: Pascal Menezes, Wajih Yahyaoui, Kapil Sharma, Warren Barkley

Publication number: 20090190726Abstract: End-to-end testing of a communications network, specifically a unified communications network, is accomplished by employing one or more sets of agents controlled by one or more organizers. Agents, capable of initiating, emulating, and recording various aspects of communication, are deployed such that call can be made through a wide range of network paths. Test scenarios defined dynamically based on network conditions or based on administrator input are executed by an organizer, which directs the agents reporting to it. Collected results are analyzed for subsequent reporting and/or corrective actions. Alert criteria may also be defined causing an alert to be issued if a significant fault is discovered.Type: ApplicationFiled: January 28, 2008Publication date: July 30, 2009Applicant: Microsoft CorporationInventors: Wajih Yahyaoui, Yiu-Ming Leung, Jeu George, Jisun Park, Rahul D.
