What is voip?4 answersVoIP, or Voice over Internet Protocol, is a technology that enables voice communication over IP networks. It converts voice data into digital code and transmits it as data packets over a network, rather than using traditional analog telephone circuits. Users can make telephone connections through devices such as PCs or regular phones, using VoIP. VoIP offers several advantages, including lower costs compared to traditional phone rates, as IP networks are global and can be accessed from anywhere. It also allows for flexibility in adding, moving, and changing IP phones, as they can be installed in any Ethernet and IP address. Asterisk is a popular software used to operate VoIP systems, and it can be installed on various operating systems. VoIP has the potential to maximize existing internet networks and reduce communication costs.
What are the parameters that affect the QoE for video streaming?5 answersThe parameters that affect the Quality of Experience (QoE) for video streaming include network parameters such as packet loss, corruption, delay, and jitter. Additionally, the visual features of the smart device, viewing distance, and content types also have a significant impact on video streaming QoE. Furthermore, the power consumption and energy efficiency of the end-user device during video streaming are important factors to consider for a sustainable use of technology. Finally, network side parameters, such as channel path loss, play a role in determining user QoE for video streaming.
What is QoS on a MQTT message?5 answersQoS on a MQTT message refers to the Quality of Service provided for the message transmission in MQTT-based IoT systems. MQTT is a lightweight publish-subscribe-based messaging protocol commonly used in IoT systems. It offers three levels of QoS for different classes of traffic. The QoS levels determine the reliability and delivery guarantees of the messages. The levels are as follows: QoS0 (at most once delivery), QoS1 (at least once delivery), and QoS2 (exactly once delivery). QoS0 provides the lowest reliability with no delivery guarantees, while QoS2 provides the highest reliability with guaranteed delivery. The choice of QoS level depends on the specific requirements of the IoT application and the importance of the data being transmitted. The QoS level can impact factors such as end-to-end delay, packet loss, and flow control in MQTT-based systems.
What are the different data visualization techniques used for QoS analysis in the telecommunication industry?4 answersDifferent data visualization techniques used for QoS analysis in the telecommunication industry include topology aggregation techniquesand machine learning algorithms for churn prediction. These techniques help in understanding and analyzing the quality of service in telecommunication networks. Topology aggregation techniques are used to abstract or summarize network topology information for routing purposes, while machine learning algorithms are used to predict potential churned customers. By using these techniques, companies can make necessary actions to reduce churn and maintain their market value.
What are some existing QoS visualisation IN TELCO OR MOBILE OPERATORS?4 answersExisting QoS visualization techniques in the telecom and mobile operator domain include the use of Ray Tracing for accurate generation of QoS maps in mobile networks. Another approach is the use of Machine Learning algorithms to abstract Telco Big Data (TBD) into compact models that can be stored and queried when necessary. Additionally, a novel heuristic called Advanced-Optimized Link State Routing (A-OLSR) protocol has been designed to provide QoS in mobile ad hoc networks (MANETs). Furthermore, resource allocation algorithms have been developed to select suitable sizes of video chunks and explore load balancing in Content Delivery Network-as-a-Service (CDNaaS) instances to increase Quality of Experience (QoE) for end users.
What are the specific parameters to measure interoperability?2 answersInteroperability parameters can be measured using various approaches. One approach is to evaluate the interoperability potential, interoperability incompatibility, and interoperability performance of enterprises. Another approach is to use a measure of interoperability that incorporates system requirements and links it to operational metrics of performance. Additionally, graph theory can be employed to evaluate industrial organizational interoperability. Furthermore, there are foundational interoperability measurement models and methodologies that have been proposed in the literature. In the context of Global Navigation Satellite Systems (GNSS), interoperability parameters can be defined based on the differences among GNSSs in terms of their effects on users in position, velocity, and timing (PVT). These parameters can be separated into signal level and message level and should be broadcast to users in a common time reference and coordinate reference frame.
