“…Among others, this successor of HTTP/1.1 offers a server push feature, allowing servers or proxies to actively push content along with previously requested content. Although a reduction of the page loading time up to 64% can be achieved in some cases, the gains of HTTP/2 are highly scenario dependent [9]. Using more intelligent web prediction algorithms, combined with HTTP/2's server push to transfer the content to the client before it is requested, can result in a further reduction of the page loading time and an improved QoE for the end user.…”

Abstract-With the increasing popularity of multimedia-rich web portals, reducing latency has become more and more important. The current median web page load time is in the order of seconds, while research has shown that user waiting times must remain below two seconds to achieve optimal acceptance. In this paper, we analyzed a large dataset obtained from a major Belgian news provider, focusing on content popularity, user activity and user preference towards article news categories. Based on this analysis, we introduce the concept of personal delivery networks (PDNs), in which content is stored closer to the end user, at delivery caches in the edge of the core network or even in the access network. PDN nodes proactively prefetch and evict content on a per-user basis, opening opportunities for personalized low-latency delivery of multimedia-rich web applications. Initial results show that a PDN-based approach allows to significantly reduce the average latency.

“…This single connection is expected to fast ramp up the available bandwidth because the initial congestion window of a TCP connection has been suggested to increase to 10 [9]. However, recent experiments have shown that under certain conditions HTTP/2.0 is only able to achieve marginal improvement when compared to its predecessor HTTP/1.0 [1], [7], [10]. Specifically, this single short-lived TCP connection may experience high idle or waiting time during the slow start phase [2], [11], and the complex object dependency within a page also aggravates the idle time [7], [12].…”

“…Specifically, this single short-lived TCP connection may experience high idle or waiting time during the slow start phase [2], [11], and the complex object dependency within a page also aggravates the idle time [7], [12]. This idle time varies according to different content sizes, bandwidth and end-to-end delay [10], thus limiting the bandwidth utilization and affecting the page load time.…”

Abstract-Due to dynamic wireless network conditions and heterogeneous mobile web content complexities, web-based content services in mobile network environments always suffer from long loading time. The new HTTP/2.0 protocol only adopts one single TCP connection, but recent research reveals that in real mobile environments, web downloading using single connection will experience long idle time and low bandwidth utilization, in particular with dynamic network conditions and web page characteristics. In this paper, by leveraging the Mobile Edge Computing (MEC) technique, we present the framework of Mobile Edge Hint (MEH), in order to enhance mobile web downloading performances. Specifically, the mobile edge collects and caches the meta-data of frequently visited web pages and also keeps monitoring the network conditions. Upon receiving requests on these popular webpages, the MEC server is able to hint back to the HTTP/2.0 clients on the optimized number of TCP connections that should be established for downloading the content. From the test results on real LTE testbed equipped with MEH, we observed up to 34.5% time reduction and in the median case the improvement is 20.5% compared to the plain over-the-top (OTT) HTTP/2.0 protocol.

“…They report that SPDY does not clearly outperform HTTP due to cross-layer dependencies between TCP and the cellular network technology. Elkhatib et al [12] conclude that SPDY may both decrease as well as increase page load times. SPDY's multiplexed connections last much longer than HTTP's.…”

HTTP Adaptive Streaming (HAS) is today the number one video technology for over-the-top video distribution. In HAS, video content is temporally divided into multiple segments and encoded at different quality levels. A client selects and retrieves per segment the most suited quality version to create a seamless playout. Despite the ability of HAS to deal with changing network conditions, HAS-based live streaming often suffers from freezes in the playout due to buffer under-run, low average quality, large camera-to-display delay, and large initial/channel-change delay. Recently, IETF has standardized HTTP/2, a new version of the HTTP protocol that provides new features for reducing the page load time in Web browsing. In this paper, we present ten novel HTTP/2-based methods to improve the quality of experience of HAS. Our main contribution is the design and evaluation of a push-based approach for live streaming in which super-short segments are pushed from server to client as soon as they become available. We show that with an RTT of 300 ms, this approach can reduce the average server-todisplay delay by 90.1 % and the average start-up delay by 40.1 %.
