Border Gateway Protocol (BGP) has been the de facto inter-domain routing protocol since it was introduced. Its destination-based routing nature, which is not able to choose a specific end-to-end AS-level route, might overload some popular peering (or inter-AS) links, while making some others underused. This could result in congestion and cause service disruption. To cope with the issue of destination-based...
Many BitTorrent clients are using these networks as a video-on-demand service, taking advantage of the popularity and the enormity of the collection of media available. However, it is a common sense that transforming the swarms into an on-demand media service causes serious damage to the overall network performance, given that streamer clients modify the method of downloading determined in the protocol...
Video content makes up more than half of the world's Internet traffic, and this figure is expected to grow rapidly. New techniques that remove traffic redundancy have been shown to significantly improve network performance since many concurrent streams deliver the same video. These techniques employ smart routers that recognize duplicated video streams and merge them to reduce traffic redundancy....
We present a new tool to help students make use of video recordings of traditional chalkboard and whiteboard lectures. Our tool provides a compact summary of a chalkboard lecture in the form of a set of slides, and an interactive environment for electronic note-taking in real time while watching a lecture in class or during review. Key to the processing of a chalkboard video by our system is the removal...
Adult video content is considered to be responsible for a major portion of the Internet traffic. We present a preliminary characterization study of one of the largest and popular adult streaming service, xHamster. While there have been extensive analysis of mainstream user generated content sharing services such as YouTube, adult streaming services have been an underappreciated field of study for...
Fueled by increasing network bandwidth and decreasing costs, the popularity of over-the-top large-scale live video streaming has dramatically increased over the last few years. In this paper, we present a measurement study of adaptive bitrate video streaming for a large-scale live event. Using server-side logs from a commercial content delivery network, we study live video delivery for the annual...
Recent measurements show that more than half of the peak time Internet traffic is due to video streaming. Recent trends also suggest that consumers are increasingly receiving their TV content over the Internet via streaming appliances that are connected to the TV. We present the first systematic measurement study of a popular class of such devices that have the ‘stick’ form factor. The study covers...
The growing of the internet use is proportional with the growing of IP address needs, but the increasing of the IP use is not equal with the number of available IPv4. Then, IPv6 was developed as a solution to overcome the limited amount of IPv4 address. Readiness of various aspects ranging from infrastructure to a service provider is required to implement IPv6. In order to improve the quality of IPv6...
Multimedia streaming is a significant source of Internet traffic, with Netflix and YouTube accounting for more than 50% of North American fixed network peak download traffic in 2016. Dynamic Adaptive Streaming over HTTP (DASH) is a recent standard for live and on-demand video streaming services, where clients adapt the video quality on-the-fly to match the network capacity by requesting multi-rate...
Anycast-based services today are widely used commercially, with several major providers serving thousands of important websites. However, to our knowledge, there has been only limited study of how often anycast fails because routing changes interrupt connections between users and their current anycast site. While the commercial success of anycast CDNs means anycast usually works well, do some users...
With the popularity of the Internet, online news media are pouring numerous of news reports into the Internet every day. People get lost in the information explosion. Although the existing methods are able to extract news reports according to key words, and aggregate news reports into stories or events, they just list the related reports or events in order. Moreover, they are unable to provide the...
The recent development of stream delivery technology made Internet broadcasting services popular. In live Internet broadcasting, broadcasters or viewers often add video or sound effects (we call this kind of live broadcasting, ‘different worlds broadcasting’). Therefore, we have proposed a distributed Internet live broadcasting system with video and audio effects. In this paper, we describe the implementation...
Network Neutrality is essential for ensuring a level playing field for the development of new applications and services on the Internet. Laws and rules alone might not be enough to protect innovation, fair competition and consumer's freedom of choice online. The research community has the responsibility to propose solutions that reveal discriminatory traffic management mechanisms on the Internet....
Content centric network (CCN) has been regarded as one of the most promising architecture solution for the future Internet, which has great advantages in support of content delivery services, such as Video-on-demand (VoD) application. Although there are some existing models proposed for the cache performance in CCN router, few of them consider the case of video request traffic. In this paper, we focus...
The growing demand for video streaming is straining the Internet, and mandating a fundamental change in future networking paradigms. Current advancements in Information-centric Networks (ICN) promise a novel approach to intrinsically handling content dissemination, caching and retrieval. While streaming technologies are converging towards Dynamic Adaptive Streaming (DAS), in-network caching in ICN...
Named Data Networking (NDN), a revolution of the IP architecture, provides an information-centric paradigm to transmit video traffic which occupies most of the Internet traffic. However, the data caching schemes exploited by the current NDN can easily result in the unfair distribution of cache space, which is not suitable for performance isolation when there are multiple network users and the cache...
Nowadays, in our fast-paced world there are countless MOOC courses in the Internet with various topics that have been designed to broaden our knowledge. One of the most powerful tools for effective learning are online videos. Many case studies have been carried out in order to specify the qualities of a good educational video. Philip J. Guo, Juho Kim and Rob Rubin published an article (How Video Production...
Among the mobile applications contributing to the surging Internet traffic, video applications are some of the biggest contributors. Most of these video applications use HTTP/HTTPS tunneling making it difficult to apply port based or packet data based identification of flows. This makes it challenging for network operators to enforce bandwidth regulation policies for app based service differentiation...
User-perceived quality-of-experience (QoE) is critical in Internet video delivery systems. Many previous efforts have studied the design of client-side bitrate adaptation algorithms to maximize single-player QoE. However, multiplayer QoE fairness becomes critical as the growth of video traffic makes it more likely that multiple players share a bottleneck in the network. Despite several recent proposals,...
Content Delivery Networks (CDN) are witnessing the outburst of video streaming (e.g., personal live streaming or Video-on-Demand) where the video content, produced or accessed by mobile phones, must be quickly transferred from a point to another of the network. Whenever a user requests a video not directly available at the edge server, the CDN network must 1) identify the best location in the network...
