Abstract: An O-DU is configured to facilitate, in a 5G wireless communication system having a DOCSIS xhaul (fronthaul, midhaul, or backhaul) transport system, pipelined 5G and DOCSIS latency. The O-DU is configured to receive a slice-, device-, and service-aware buffer status report (SDSABSR) indicating a UE is requesting an uplink grant for data transmission in the 5G wireless communication system; generate, based on the SDSABSR, a slice-, device-, and service-aware bandwidth reporting (SDSABR) trigger for a CMTS; and provide to the CMTS the SDSABR trigger to cause the CMTS to make QoS and resource granting decisions relative other requests from other devices in response to the SDSABR trigger and before receiving the data transmission.

The chassis may be configured to be mounted in an appliance rack. A front vent on the front side of the chassis may be configured to allow air to flow between an external environment and the front compartment. A front loading module mountable in the front compartment may include a heat generating device. A front loading airflow module may be configured to draw in air within the front compartment into the front loading airflow module in a first direction and force air out of the front loading airflow module into the rear compartment in a second direction such that air is drawn in the front vent, over the heat generating device of the front loading module, and forced rearward over rear heat generating devices and out a rear vent of the chassis. The first direction may be substantially orthogonal to the second direction.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: The embodiments disclosed herein relate to a system and method for redirecting unauthorized user equipment (UE) from a femto base station (BS) to a macro network. The system checks whether the UE is authorized or not by comparing the identifier of the UE with a list of authorized UE that are stored in the memory of the femto BS. If the UE is found to be unauthorized, the UE is redirected to the macro network.

Abstract: A method for load balancing by updating session information in a multi-blade load balancer is disclosed herein. The method may include distributing information about a local session table by a blade in the multi-blade load balancer to at least one other blade in the multi-blade load balancer. The method may also include updating a local session table by the at least one other blade on receiving the distributed information. The method may also include session table update for protocols including a control plane and data plane component.

Abstract: 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.

Abstract: 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.
