Patent number: 8918523Abstract: A graphical user interface (GUI) is disclosed that allows a user to identify routers, communities, residents and media aggregation managers existing on a network. The user may interactively select a path that includes two media aggregation managers and at least one router. The GUI predicts scheduled bandwidth utilization along the selected path for a variety of residents wishing to communicate across the path. The GUI may be utilized for initializing all media aggregation managers on the network along with provisioning each of the routers on the selected path. The GUI provisions all of the routers and initializes all of the media aggregation managers on the selected path simultaneously in order to accomplish the predicted schedule of usage provided by the GUI to the user and force all communication packets communicated between the residents to travel along the selected path.Type: GrantFiled: May 11, 2012Date of Patent: December 23, 2014Assignee: Prom KS Mgmt Limited Liability CompanyInventors: Siddhartha Nag, Alfred D'Souza, Naveed Alam, Rakesh Patel

Patent number: 8458332Abstract: Apparatus and methods are provided for multiplexing application flows. According to one embodiment, a predetermined portion of available bandwidth is reserved over a path through a network communicatively coupling a first network device associated with a first set of terminals and a second network device associated with a second set of terminals for real-time communication sessions among multiple applications running on the first set of terminals and the second set of terminals as a real-time bandwidth pool. The real-time bandwidth pool is thereafter shared among multiple real-time communication sessions involving one or more terminals in the first set of terminals and one or more terminals in the second set of terminals by selectively admitting application sessions involving the one or more terminals in the first set of terminals and the one or more terminals in the second set of terminals based upon currently available resources in the real-time bandwidth pool.Type: GrantFiled: November 4, 2005Date of Patent: June 4, 2013Assignee: Prom KS Mgmt Limited Liability CompanyInventors: Siddhartha Nag, Alfred D'Souza, Naveed Alam

Patent number: 8428074Abstract: Disclosed herein is a method of executing the RAS stage up to the set-up stage in a H.323 system. The H. 323 system comprises one or more third party gatekeepers and one or more end points. A transparent back-to-back proxy gatekeeper is introduced between a third party gatekeeper and end-points. Two sets of ports are created on the transparent back-to-back proxy gatekeeper. One set of ports represent themselves as end-points to the third party gatekeeper and the other set of ports represent themselves as known ports of the third party gatekeeper to the end point. A H.323 RAS request is intercepted transparently from an end-point to a third party gatekeeper. The H.323 RAS request is addressed to a well-known port number on the third party gatekeeper. The information of the H.323 RAS registration request is stored in a local persistent copy within the back-to-back proxy gatekeeper. The H.323 RAS registration request is passed to the well-known port number on the third party gatekeeper.Type: GrantFiled: April 24, 2006Date of Patent: April 23, 2013Assignee: Prom KS Mgmt Limited Liability CompanyInventors: Siddhartha Nag, Bo Shu, Rahul Gulati, Ilana Polyak

Patent number: 8032646Abstract: Methods and apparatus are provided for administering a communication network. In one embodiment, a first interface screen depicts nodes within a network. The nodes include a pair of media aggregation managers providing multiplexing/demultiplexing of media traffic associated with multiple application sessions between a pair of communities onto a preallocated reservation protocol session between the media aggregation managers. The media aggregation managers are visually distinguishable from other nodes. A second interface screen depicts potential paths through the network. Each potential path is capable of transferring media packets between the media aggregation managers.Type: GrantFiled: July 14, 2005Date of Patent: October 4, 2011Assignee: Prom KS Limited Liability CompanyInventors: Siddhartha Nag, Alfred D'Souza, Naveed Alam, Rakesh Patel

Patent number: 7266683Abstract: Apparatus and methods are provided for multiplexing and selectively encrypting application flows, such as VoIP services, over a pre-allocated bandwidth reservation protocol session. According to one embodiment, a pre-allocated reservation protocol session, such as an RSVP session, is shared by one or more individual application sessions. The reservation protocol session is pre-allocated over a path between a first network device associated with a first user community and a second network device associated with a second user community based upon an estimated usage of the path for individual application sessions between users of the first and second user communities. Subsequently, the one or more individual application sessions are dynamically aggregated by multiplexing application flows associated with the one or more individual application sessions onto the pre-allocated reservation protocol session at the first network device and demultiplexing at the second network device.Type: GrantFiled: July 27, 2002Date of Patent: September 4, 2007Inventor: Siddhartha Nag
