“…Considerable latency may occur when each data packet in a multiway multimedia streaming system reaches the receiving end through different routes. Therefore, during the mixing process, a synchronization mechanism is also necessary to ensure that the audio and video of the mixed stream are synchronized [26], [32]. The key technical methods used are buffer mechanisms, timeline mechanisms [27], and multisource coordination mechanisms [26].…”

The key technical methods used are buffer mechanisms, timeline mechanisms [27], and multisource coordination mechanisms [26]. The core solution to the problem is to ensure in-stream synchronization under network latency and bandwidth first and to watch this play synchronously, thus reducing the latency while ensuring the fidelity of the stream [27].…”

The WebRTC protocol can provide live streaming of peer-to-peer connections via JavaScript (JS) application programming interface (API) calls to a web browser. However, the protocol is restricted to a small number of peers because there is no simple way to mix real-time streams from multiple peers and then distribute the mixed stream to a large number of audiences. For example, it is necessary to mix audio and video streams from peers in a conversation and broadcast the real-time mixed stream to more than 10k audiences who only watch the video. It is also necessary to blend synchronous content (e.g., logos, music) to the live conversation stream. WebRTC does not currently provide a mechanism to easily support these cases. This paper proposes a method for the synchronized mixing of real-time audio/video streams from multiple peers while minimizing latency. This method enables the implementation of an online live conversation system that is able to mix live conversation streams from multiple peers and then rebroadcast the mixed stream to a large number of audiences.INDEX TERMS WebRTC, real-time multimedia communications, live streaming, synchronization mechanism, media synchronization.

Computer network is an interface of two or more computers that is built for the purpose of sharing, information, data, and resources. Computer network has nodes that serve as the origin, route, and receiver of data. Computer network is built using a combination of hardware and software. LANs and WLANs are the most common form of computer network and they are used intensively and extensively in CAD/CAM/CAE applications. This review talks about the latest implementation of LANs/WLANs in CAD/CAM/CAE applications, their limitations, and consideration for their usage. There are four aspects that a LAN/WLAN system must fulfill which are Fast, Expandable, Reliable, and Secure. LAN and WLAN including their many standards each has different properties which influence their implementation in CAD/CAM/CAE applications.

“…In PM-NSI, we aim at predicting accurate NSI while collecting NSI at longer periods. To do that, we use Variable Packet Size (VPS) probing technique [16][17][18][19][20]. The main idea behind the technique is to measure the remaining bandwidth capacity of each link of the path by probing the demand of the flow requests.…”

In a Software-Defined Wide Area Network (SD-WAN), a logically centralized controller is responsible for computing and installing paths in order to transfer packets among geographically distributed locations and remote users. Accordingly, this would necessitate obtaining the global view and dynamic Network State Information (NSI) of the network. Therefore, the centralized controller periodically collects link-state information from each port of each switch at fixed time periods. While collecting NSI in short periods causes protocol overhead on the controller, collecting in longer periods leads to obtain inaccurate NSI. In both cases, packet losses are inevitable, which is not preferred for Quality of Service (QoS). Packet loss needs to be reduced by minimizing the protocol overload on the controller and collecting accurate NSI to provide better QoS. This work proposes an effective Prediction Method for collecting NSI (PM-NSI ) that significantly reduces packet loss and controller protocol load allowing the controller to collect accurate NSI in longer periods. The proposed method is compared against the existing NSI collection method, which collects NSI periodically, in use on the RYU controller and the Mininet emulator by using a dynamic routing algorithm. The test results indicated that PM-NSI reduces controller load around 1000% by collecting NSI in longer periods and so outperforms the existing periodic NSI collection method in terms of packet loss, jitter, controller load, and thus QoS.
