The IEEE 802.1Q-2018 standard embeds in Ethernet bridges novel features that are very important for automated driving, such as the support for time-driven communications. However, cars move in a world where unpredictable events may occur and determine unforeseen situations. To properly react to such situations, the in-car communication system has to support event-driven transmissions with very low and bounded delays. This work provides the performance evaluation of EDSched, a traffic management scheme for IEEE 802.1Q bridges and end nodes that introduces explicit support for event-driven real-time traffic. EDSched works at the MAC layer and builds upon the mechanisms defined in the IEEE 802.1Q-2018 standard.

With the continuous development of information technology, real-time audio and video communication is becoming more and more important in people's daily life. At present, there are a lot of software with audio and video communication function in the market, such as Tencent QQ software, wechat, nailing, etc. these software are developed with C / S architecture, and can not achieve cross platform and cross terminal. Users need to download the software to carry out audio and video communication. In view of this, this paper uses webrtc technology based on ice framework to realize the design of remote audio and video communication system, completes the internal network penetration, establishes the communication process between clients, designs room server and signaling server for conversation, and completes the design of remote network audio and video communication system.

This paper describes the design and prototype implementation of a communication platform aiming to provide voice and video communication in a distributed networking environment. Performance considerations and network characteristics have also been taken into account in order to provide the set of properties dictated by the sensitive nature and the real-time characteristics of the targeted application scenarios. The proposed system has been evaluated both by experimental means as well as subjective tests taken by an extensive number of users. The results show that the proposed platform operates seamlessly in two hops, while in the four hops scenario, audio and video are delivered with marginal distortion. The conducted survey indicates that the user experience in terms of Quality of Service has obtained higher scores in the scenario with the two hops.
