What are the current developments for QoS in network services?

2 Cloud and QoS

Cloud computing is the delivery of computing resources and services over the internet, such as storage, processing, networking, and software. Cloud services enable users to access and scale resources on demand, without investing in costly infrastructure. However, cloud services also pose challenges for QoS, such as network congestion, resource contention, and security threats. The current trends for QoS in cloud include multi-cloud orchestration, network function virtualization, edge computing, and service level agreements.

3 IoT and QoS

Internet of things (IoT) is the network of physical devices, sensors, actuators, and applications that collect, exchange, and process data over the internet. IoT enables various applications, such as smart cities, smart homes, smart healthcare, and smart industry. However, IoT also introduces QoS issues, such as heterogeneity, scalability, reliability, and energy efficiency. To address these challenges, the field is exploring new standards such as fog computing, MQTT and CoAP protocols, and QoS-aware routing.

4 SDN and QoS

Software-defined networking (SDN) is a paradigm that separates the control plane and the data plane of a network, allowing centralized and programmable management of network resources and policies. SDN enables network operators to dynamically optimize network performance, security, and efficiency. However, SDN also requires QoS mechanisms to ensure the quality of control and data traffic, as well as the quality of user applications. Some of the current trends and standards for QoS in SDN include OpenFlow protocol, intent-based networking, QoS-aware scheduling, and QoS-aware routing.

5 QoS and traffic engineering

Traffic engineering is the process of optimizing the performance and utilization of network resources by controlling the routing, allocation, and prioritization of traffic flows. Traffic engineering is essential for QoS, as it enables network operators to meet the diverse and dynamic requirements of different applications and users. Various trends and standards are currently in place for QoS and traffic engineering, including segment routing, multiprotocol label switching (MPLS), differentiated services (DiffServ), and integrated services (IntServ).

6 QoS and network architecture

Network architecture is the design and structure of a network, including its components, protocols, functions, and interactions. Network architecture determines the capabilities and limitations of a network, as well as its QoS performance. Therefore, network architects need to consider QoS as a key factor in their network design and evaluation. Some of the latest developments in QoS and network architecture involve service-oriented architecture (SOA), network virtualization, network automation, and network analytics.
