Abstract
The smart cities provide a better connection between services and citizens based on new Internet technologies. During the building process of smart cities, some burgeoning applications have been emerging and changing the daily lifestyle of people, e.g., live streaming applications. Especially, the live-soccer event applications have attracted much attention and can improve people’s enjoyment of life to a great extent, such as the Europe five major league matches and FIFA world cup. For such applications, the traditional routing strategies cannot do Quality-of-Service (QoS) awareness, and thus, the network performance and the Quality of Experience (QoE) of users cannot be guaranteed. In this paper, we employ Software-Defined Networking (SDN) to make QoS awareness for the special live-soccer event applications, in which the QoS-aware routing mechanism is proposed, called LSEA. Meanwhile, delay, delay jitter, and packet loss rate are considered as three objects. On this basis, the improved Dijkstra routing algorithm and SDN-based disjoint routing algorithm are devised. Finally, the proposed LSEA is implemented over Mininet, and the experimental results demonstrate its feasibility and efficiency.
Highlights
With the rapid development of new Internet technologies such as mobile edge computing [1], 5G [2], and Internet of Things (IoT) [3], the building of smart cities [4, 5] has attracted much attention from many countries and regions, which can provide a better connection between services and citizens based on the combination of these new Internet technologies
(1) Software-Defined Networking (SDN)-based QoSaware routing model is introduced, where delay, delay jitter, and packet loss rate are considered as three objects for optimization
The improved Dijkstra routing is the foundation of SDN-based disjoint routing
Summary
With the rapid development of new Internet technologies such as mobile edge computing [1], 5G [2], and Internet of Things (IoT) [3], the building of smart cities [4, 5] has attracted much attention from many countries and regions, which can provide a better connection between services and citizens based on the combination of these new Internet technologies. SDN can obtain the global network view and status information, such as flow statistics, the availability of network resources, the network topology information, and even the more detailed forwarding/routing information On this basis, the control plane of SDN gives real-time control policies, and they are devolved to the data plane, which can guarantee the unified management and configuration for the network resources. SDN can provide the differentiated end-to-end services for the special livesoccer event applications, greatly enhancing the network performance and improving the watching quality. We in this paper plan to employ SDN to make QoS awareness for the special live-soccer event applications in smart cities, in which the QoS-aware routing mechanism is proposed, called LSEA.
