“…However, the workload of CTR controller is closely related to the network scale. Therefore, with the increase of nodes and requests in the network, the controller will be configured with huge computing and storage capacity to provide efficient network management [18], [19]. On the other hand, due to the limited computing and storage resources of the controller, the single controller is vulnerable to the threat of a single fault, and the large number of requests may saturate the capacity of the controller.…”

In view of the inherent defects of traditional network protocols, unreasonable video content distribution process, content scheduling and routing mechanism need to be optimized in the current edge computing (EC) network. A centralized control EC network architecture of named data networking (NDN) is proposed in this paper. EC nodes are deployed on the edge of the network to provide caching and computing capabilities, and distribute video streams. So that transmission delay is reduced, bandwidth cost is saved, and the quality of experience (QoE) is improved. Firstly, the communication mechanism of NDN is introduced to distribute content and improve the efficiency of content distribution. In the scheme, the content distribution mechanism of video stream is improved in a distributed way. Different bit rate versions of video clips are distributed and buffered on the distributed EC nodes, so as to avoid redundant cache and save storage resources. In addition, the user interest content model is constructed. That is, video is divided into different categories according to content and user content preference model. Finally, with the limited cache and computing resources of EC nodes, the software defined network (SDN) mechanism is introduced for centralized management and control. And it provides a solution for content scheduling problem under resource constraints. In the scheme, the content distribution mode is decided by the effective arrangement of network resources, and the user's request is processed and responded cooperatively to avoid redundant cache and transmission. Based on the selection of forwarding response mode, the distributed characteristics of EC nodes and the routing and forwarding mechanism of NDN are fully utilized to provide users with response. It is shown by the experimental results that the proposed scheme optimizes the load on the network side and the experience of the client to a certain extent.INDEX TERMS Video distribution, edge computing (EC), user content preference model, adaptive bit rate (ABR), information centric networking (ICN).

“…After years of effort, it is turned into an RFC as a method to perform packet loss, delay, and jitter measurements on live traffic [9]. And currently, AM-PM is under development in the IETF in the context of various encapsulation protocols, including MPLS, QUIC and Geneve [17].…”

“…For instance, a variant of AM-PM is already implemented in commodity network devices by Huawei, which was called Packet Conservation Algorithm for Internet (iPCA) [19]. Similarly, Telecom Italia has been using and testing the AM-PM methods in very large deployments with cellular networks [17]. Additionally, [8] presents a detailed implementation approach of AM-PM that was applied to one hardware and one software-based implementation along with experimental evaluation results.…”

For continuous, persistent and problem-free operation of Industrial Wireless Sensor Networks (IWSN), it is critical to have visibility and awareness into what is happening on the network at any one time. Especially, for the use cases with strong needs for deterministic and real-time network services with latency and reliability guarantees, it is vital to monitor network devices continuously to guarantee their functioning, detect and isolate relevant problems and verify if all system requirements are being met simultaneously. In this context, this article investigates a lightweight telemetry solution for IWSNs, which enables the collection of accurate and continuous flowbased telemetry information, while adding no overhead on the monitored packets. The proposed monitoring solution adopts the recent Alternate Marking Performance Monitoring (AM-PM) concept and mainly targets measuring end-to-end and hopby-hop reliability and delay performance in critical application flows. Besides, the technical capabilities and characteristics of the proposed solution are evaluated via a real-life implementation and practical experiments, validating its suitability for IWSNs.

“…AM-PM was first introduced in [6], and has been under discussion in the IETF for a few years [8]. A tutorial of AM-PM [16] is currently under review. TimeFlip was first introduced in [17], and [15] showed that TimeFlip can be applied to Alternate 6 Due to a limitation in our software implementation we did not test shorter measurement intervals.…”

Network telemetry is a key capability for managing the health and efficiency of a large-scale network. Alternate Marking Performance Measurement (AM-PM) is a recently introduced approach that accurately measures the packet loss and delay in a network using a small overhead of one or two bits per data packet. This paper introduces a novel time-multiplexed parsing approach that enables a practical and accurate implementation of AM-PM in network devices, while requiring just a single bit per packet. Experimental results are presented, based on a hardware implementation, and a software P4-based implementation.
