In recent years, the quality of 360 <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">${}^{\circ }$</tex-math></inline-formula> video over bandwidth-constrained networks has received a lot attention. To reduce bandwidth cost, some tile-based streaming systems split spatially into variable-sized coarse-grained tiles by grouping areas with similar levels. However, these approaches do not minimize number tiles,...

Modern data centers host diverse applications, which generate a mix of short flows with stringent latency requirement and long requiring large sustained throughput. To solve the problem resource competition between mixed flows, we propose an adaptive traffic isolation scheme APS. Based on packet spraying in multipath transmission, APS dynamically separates from ones different paths to provide low for flows. Meanwhile, resolve out-of-order problem, limits few Equal Cost Multi Path (ECMP)....

Autophagy modulation has been considered a potential therapeutic strategy for human chondrosarcoma, and previous study indicated that salidroside exhibits significant anti-carcinogenic activity. However, the ability of to induce autophagy its role in chondrosarcoma cell death remains unclear.We exposed SW1353 cells different concentrations (0.5, 1 2 mM) 24 h. RT-PCR, Western-blotting, Immunocytofluorescence, Luciferase Reporter Assays were used evaluate whether activated TFEB-dependent...

Mobile video streaming dominates today's network traffic, and adaptive bitrate (ABR) algorithms have been routinely adopted for transmitting media content across dynamic mobile networks. State-of-the-art ABR mainly alter without considering audio as they consider the impact on negligible due to their small size. However, bring users an immersive experience, recent providers applied high-quality with large sizes, like stereophonic sound. Therefore, improper selection will adversely affect...

Modern data center topologies often take the form of a multi-rooted tree with rich parallel paths to provide high bandwidth. However, various path diversities caused by traffic dynamics, link failures and heterogeneous switching equipments widely exist in production datacenter network. Therefore, multi-path load balancer should be robust these diversities. Although prior fine-grained schemes such as RPS Presto make full use available paths, they are prone experience packet reordering problem...

Due to the explosive growth of all kinds Internet services, data centers have become an irreplaceable and vital infrastructure support this soaring trend. Compared with traditional networks, center networks (DCNs) unique features, such as high bandwidth, low latency, many-to-one communication mode, shallow buffered switches, multi-root topology. These new characteristics pose a lot challenges previous network technics (e.g., Ethernet, Equal Cost Multi-path (ECMP), TCP), making them hard...

Adaptive Bitrate (ABR) algorithms have become increasingly important for delivering high-quality video content over fluctuating networks. Considering the complexity of scenes, chunks can be separated into two categories: those with intricate scenes and simple scenes. In practice, it has been observed that improving quality yields more substantial improvements in Quality Experience (QoE) compared focusing solely on chunks. However, current ABR schemes either treat all equally or rely fixed...

To improve the quality of experience for worldwide users, an increasing number service providers deploy their services on geographically dispersed data centers, which are connected by wide area network (WAN). In cross-datacenter networks, however, intra- and inter-datacenter parts have different characteristics, including switch buffer depth, round-trip time bandwidth. Besides, most intra-DC flows belong to interactive that require low delay while inter-DC typically need achieve high...

Datacenter networks provide large bisection bandwidth by load balancing traffic over rich parallel paths in multi-rooted tree topologies. Nevertheless, production datacenters operate under various path diversities caused dynamics, hardware failures and heterogeneous switching equipment. Therefore, the schemes data center should be resilient to network asymmetry.

Explicit Congestion Notification (ECN) is widely utilized in modern data centers to achieve low latency and high throughput for various applications. In recent years, however, even with the sustainable growth of link bandwidth centers, switch buffer size does not increase remarkably. Consequently, standard per-port ECN scheme suffers from excessive packet loss. Though shared-buffer alleviates loss, we observe that it leads severe unfairness, which term as Port Starvation problem. When flows...
