“…On the other hand, the explicit approach is ECNlike explicit congestion detection where the router explicitly notifies congestion status on the communication path to the client. Since the explicit approach enables it to notify congestion status of the network explicitly with short communication delay between the client and the router, communication performance is better than that of the implicit approach [17]- [19]. However, despite the implicit bitrate adaptation causes QoE degradation due to congestion as described in 2.2, adaptive streaming using explicit feedback of congestion status is not well considered.…”

“…However, despite the implicit bitrate adaptation causes QoE degradation due to congestion as described in 2.2, adaptive streaming using explicit feedback of congestion status is not well considered. Then, our proposal stands for the idea of the adaptive streaming for congestion detection using feedback of explicit congestion status based on the router's packet queue length [18], [19] by introducing the upper band of the selectable bitrate to the bitrate adaptation in the client. 3 shows an overview of CAAS with ECN.…”

“…In ICN research fields, some explicit congestion control applying the idea of Explicit Congestion Notification (ECN) is proposed for better communication performance than that of implicit congestion control [17]- [19]. These approaches focused on the characteristic of ICN where routers work in a distributed manner and propose congestion control in which routers notify explicit feedback of congestion status to the clients.…”

“…In this paper, we propose a congestion-aware adaptive streaming over ICN combined with explicit congestion notification (CAAS with ECN) for QoE, which applies the idea of ECN to an adaptive streaming application to avoid QoE degradation. The design of CAAS with ECN employs an ECN framework based on congestion detection measuring the packet queue length of each router's interface [18], [19]. CAAS with ECN enables the router to notify an upper band of the selectable bitrate (bitrate-cap as ECN) to the client for adjusting the bitrate while local congestion is detected.…”

Recently, adaptive streaming over information centric network (ICN) has attracted attention. In adaptive streaming over ICN, the bitrate adaptation of the client often overestimates a bitrate for available bandwidth due to congestion because the client implicitly estimates congestion status from the content download procedures of ICN. As a result, streaming overestimated bitrate results in QoE degradation of clients such as cause of a stall time and frequent variation of the bitrate. In this paper, we propose a congestion-aware adaptive streaming over ICN combined with the explicit congestion notification (CAAS with ECN) to avoid QoE degradation. CAAS with ECN encourages explicit feedback of congestion detected in the router on the communication path, and introduces the upper band of the selectable bitrate (bitrate-cap) based on explicit feedback from the router to the bitrate adaptation of the clients. We evaluate the effectiveness of CAAS with ECN for client's QoE degradation due to congestion and behavior on the QoS metrics based on throughput. The simulation experiments show that the bitrate adjustment for all the clients improves QoE degradation and QoE fairness due to effective congestion avoidance.

“…As an alternative approach for transport control in ICN research areas, an explicit congestion control, which applies the idea of explicit congestion notification (ECN), is proposed for better communication performance than that of conventional implicit congestion control [14]- [16]. These approaches propose feedback-enabled congestion control in which routers explicitly notify the local congestion state to the clients on a communication path.…”

Recently, information centric network (ICN) has attracted attention because cached content delivery from router's cache storage improves quality of service (QoS) by reducing redundant traffic. Then, adaptive video streaming is applied to ICN to improve client's quality of experience (QoE). However, in the previous approaches for the cache control, the router implicitly caches the content requested by a user for the other users who may request the same content subsequently. As a result, these approaches are not able to use the cache effectively to improve client's QoE because the cached contents are not always requested by the other users. In addition, since the previous cache control does not consider network congestion state, the adaptive bitrate (ABR) algorithm works incorrectly and causes congestion, and then QoE degrades due to unnecessary congestion. In this paper, we propose an explicit cache placement notification for congestion-aware adaptive video streaming over ICN (CASwECPN) to mitigate congestion. CASwECPN encourages explicit feedback according to the congestion detection in the router on the communication path. While congestion is detected, the router caches the requested content to its cache storage and explicitly notifies the client that the requested content is cached (explicit cache placement and notification) to mitigate congestion quickly. Then the client retrieve the explicitly cached content in the router detecting congestion according to the general procedures of ICN. The simulation experiments show that CASwECPN improves both QoS and client's QoE in adaptive video streaming that adjusts the bitrate adaptively every video segment download. As a result, CASwECPN effectively uses router's cache storage as compared to the conventional cache control policies.
