Patent number: 12088342Abstract: A transport domain orchestrator (TDO) in a 5G network provides for dynamic configuration of a transport network resource (e.g., ports) and of a corresponding set of VLAN IDs to support a 5G service within a corresponding passive optical network (PON) transport network slice. The TDO, in response to a query in connection with establishing the 5G service, determines PON ports available in the PON to support the 5G service within the corresponding PON transport network slice; allocates the transport network resource for the corresponding PON transport network slice; determines the corresponding set of VLAN IDs for the 5G service, in which the corresponding set of VLAN IDs map the 5G service to the corresponding PON transport network slice and to the set of PON ports; and configures the PON to support the 5G service in the corresponding PON transport network slice, identified by the corresponding set of VLAN IDs.Type: GrantFiled: December 7, 2022Date of Patent: September 10, 2024Assignee: Radisys CorporationInventors: Subramanya Bhatkal Nagesh, Rajendra Prasad Kodaypak

Patent number: 8879438Abstract: System and methods provide acoustic echo monitoring and cancellation for real time media processing in an internet protocol (IP) media server in an IP network. An echo monitor is configured to selectively compare audio streams into and out of the IP media server through a selected port. The comparison determines an occurrence of an echo. An echo canceller in communication with the echo monitor is configured to respond to the determination by the echo monitor so as to remove the echo from at least one of the audio streams. A talk burst detector may be used to detect speech in at least one of the audio streams through the selected port. The echo monitor selectively compares the audio streams in response to a signal from the talk burst detector that indicates detection of speech.Type: GrantFiled: May 10, 2012Date of Patent: November 4, 2014Assignee: Radisys CorporationInventors: Adnan Saleem, Mohammed Aamir Husain, Timothy S.

Patent number: 8848536Abstract: Stateless load balancing of network packets within a system avoids detection by a network client or end user for deep packet inspection or other bump-in-the-wire applications. At least one header field of a received packet is used in generating a hash value. The hash value is used to identify a processing resource within the system for processing the received packet. Before being sent to the identified resource, the received packet is encapsulated with a new header that includes an indication of ingress port. The encapsulation does not modify the original packet. On a return path from the identified processing resource, the ingress port is determined from the encapsulated packet, the encapsulated packet is decapsulated to obtain a recovered packet that is identical to the received packet, and the recovered packet is forwarded to the network through an egress port as determined from the recovered ingress port.Type: GrantFiled: August 30, 2013Date of Patent: September 30, 2014Assignee: RadiSys CorporationInventors: Michael W. Hu, Andrew P. Alleman

Patent number: 8711681Abstract: Backplane redundancy is provided for a system including multiple nodes that communicate packets through first and second switches. Assuming that the first switch is initially assigned to an active state and the second switch to a standby state, the nodes communicate the data packets through physically enabled first backplane links to the first switch. The nodes physically enable second backplane links that are in a condition to communicate the data packets to the second switch. A messageless failover process is initiated by temporarily disabling, at the first switch, the first backplane links between the first switch and the nodes. In response to the nodes detecting the disabled first backplane links to the first switch, the nodes reconfigure themselves to communicate the data packets through the second backplane links to the second switch and to stop communicating the packets through the first backplane links to the first switch.Type: GrantFiled: February 8, 2012Date of Patent: April 29, 2014Assignee: Radisys CorporationInventors: Michael W.

Publication number: 20130052989Abstract: A system and method for achieving load balancing in a communication network. Each User Equipment (UE) configured to a Femto Access Point (FAP) is grouped under a particular access class based on the quality of service being subscribed to, by the UE. At the time of overloading, each access class is barred access for a particular percent of duty cycle. When an authorized UE requests connection to the FAP, the system checks for an overloading situation. If overloading is detected in the network, the system identifies the access class of that particular UE and checks if that particular access class is authorized to access the FAP at that particular instant of time. If the UE's access class is authorized to access the FAP at that instant of time, the system allow UE to establish connection.Type: ApplicationFiled: August 24, 2011Publication date: February 28, 2013Applicant: RadiSys CorporationInventor: Nagi Jayaraman Mahalingam

Patent number: 8226340Abstract: A system and method for access control to a Femto cell network. The system prevents access for unauthorized user equipments (UE) to a Femto cell with a particular Location Area Code (LAC) by temporarily averting access to that particular FAP. If the Femto cell Access Point (FAP) gets a connection request from an unauthorized UE, the FAP fails the first authentication check for that particular UE. Upon authentication failure, the UE activate a first timer and checks if the FAP sends a second authentication request before expiry of the first timer. In an embodiment, FAP does not send second authentication request if the UE is found to be unauthorized. Then the UE activates a second timer and goes to idle state. Further, the UE will not scan for FAPs with that particular Location Area Code till expiry of the second timer.Type: GrantFiled: August 24, 2011Date of Patent: July 24, 2012Assignee: Radisys CorporationInventor: Nagi Jayaraman Mahalingam
