Abstract: State of the art data transmission approaches require all the lost data packets to be retransmitted, which may not be required in a variety of scenarios. Existing protocols lack the option to change packet semantics on the fly for individual fragments on the fly for the same stream. Also, parameters including maximum number of retransmissions permitted are set beforehand, one for entire stream. Method and system in embodiments disclosed herein provide an approach for context-based retransmission of lost packets. Method and system disclosed in the embodiments herein identifies one or more packets as lost packets based on reception status of acknowledgement (ACK) within a dynamically adaptive timeout period, and then based on value of a NRTx header field associated with the lost packet, determines whether or not to retransmit the lost packet. Value of the dynamically adaptive timeout period is recalculated dynamically, based on a determined instantaneous channel condition.

Abstract: This disclosure provides a Kalman filter based predictive jitter buffer adaptation for smooth live video streaming. In the present disclosure, at receiver of a live video steaming system, reassembly of received data packets is performed to reconstruct different types of encoded frames transmitted by a transmitter. The different types of encoded frames are Full encoded frames in basic state and Delta encoded frames. To tackle data packet loss, the receiver is also equipped with a frugal yet efficient loss handling mechanism for both basic and delta frames. To achieve smooth rendering of the live video, the receiver employs a Kalman Filter based Jitter Buffer Adaptation mechanism. The Kalman Filter based Jitter Buffer Adaptation mechanism observes variability in arrival time of the open-loop best-effort traffic and adapts a jitter-buffer based on future end-to-end delay estimates. Thus, smoothness of streaming is preserved at the receiving end augmented with robust loss-resilience.

Abstract: The present disclosure relates to methods and systems for establishing an edge-inclusive real-time multimedia tele-conferencing using tele-robots. Conventional techniques employ a WebSocket connection for the robot-to-edge device (R2E) connection which may not meet expected real-time behaviour. The present disclosure provides a resource-friendly application protocol using WebRTC that enables the same tele-robotic WebRTC session to fork the live feed of the tele-robot for consumption by the edge device. According to the present disclosure, a peer-to-peer connection is established between the plurality of peers by the cloud signaling server, based on the type of the unique type identifier.

Abstract: In some implementations, a first network device that hosts a bridge domain (BD) may receive inter-subnet multicast traffic associated with the BD. The BD may forward, using a supplemental bridge domain (SBD) interface of the first network device, and via an SBD, a first copy of the inter-subnet multicast traffic to a second network device that hosts the BD. The first network device may forward, using the SBD interface and via the SBD, a second copy of the inter-subnet multicast traffic to a third network device that does not host the BD. The first network device may forward, using an integrated routing and bridging (IRB) interface of the first network device associated with the BD, a third copy of the inter-subnet multicast traffic to a fourth network device that hosts the BD (e.g., when the fourth network device is a multihoming peer of the first network device).

Abstract: A Method for Estimating State of Charge and State of Health of Battery and a System thereof The present invention relates to a method (200) and system (100) for estimating state of charge and state of health of a battery (10). A first vector (x) and a second vector (0) are initialised. The first vector (x) is estimated and updated by a first state-space filter based first equivalent circuit solver by assuming a fixed value of the second vector (0). the second vector (0) is estimated and updated based on an Electrochemical Model and then by a second state-space filter based second equivalent circuit solver. The updated values of the second vector (0) by the Electrochemical Model and the second state-space filter based equivalent circuit solver are merged. The state of charge is obtained from the updated value of the first vector (x), and the state of the health is obtained from the merged and updated value of the second vector (0).
