With the advent of 5G networks and the rise of the Internet of Things (IoT), Content Delivery Networks (CDNs) are increasingly extending into the network edge. This shift introduces unique challenges, particularly due to the limited cache storage and the ...

Improving hit rates can be achieved by enhancing cache replacement algorithms with the identification of zero-reuse objects (ZROs) and inserting them at the end of the cache queue. Note that the promotion policy needs to achieve a similar task as the ...

The most challenging issue in content delivery networks (CDN) is to place the surrogate servers. K-means clustering can be chosen as a very simple and effective approach for placing the surrogates over the network. But the main concern of this approach is ...

Caching systems have long been crucial for improving the performance of a wide variety of network and web-based online applications. In such systems, end-to-end application performance heavily depends on the fraction of objects transferred from the cache, ...

In recent years, video has become a tremendous growth of media in the content delivery network (CDN) coupled with the enormous increase of users. However, it leads to new challenges including an explosion of data demand on networking resources, backhaul ...

The volume of data moving through a network increases with new scientific experiments and simulations. Network bandwidth requirements also increase proportionally to deliver data within a certain time frame. We observe that a significant portion of the ...

Remote Direct Memory Access (RDMA) can be deployed in Content Delivery Networks (CDN) Points of Presence (PoPs) to avoid the high CPU overheads caused by traditional TCP/IP stacks. However, RDMA cannot surmount the drawbacks of the window-based ...

The efficient data dissemination in an infrastructure-less environment as MANET is the challenging issues. This paper proposes to adopt the CDN Technique for disseminating information in MANET. The source node disseminates data to surrounding nodes by ...

The dynamic content distribution problem addresses the trade-off between storage and delivery costs in modern virtual content delivery networks (CDNs). That is, a video file can be stored in multiple places so that the request of each user is served from a ...

Recent years have witnessed a rapid increase of crowdsourced live streaming (CLS): applications like Twitch.tv have attracted millions of daily active users. Content delivery in such crowdsourced live streaming involves two phases: 1) Video stream (i.e.,...

Content Delivery Networks (CDNs) cache and serve a majority of the user-requested content on the Internet, including web pages, videos, and software downloads. We propose two TTL-based caching algorithms that automatically adapt to the heterogeneity, ...

The semantics of online authentication in the web are rather straightforward: if Alice has a certificate binding Bob's name to a public key, and if a remote entity can prove knowledge of Bob's private key, then (barring key compromise) that remote ...

Content delivery networks (CDNs) operate hundreds of thou sands of servers that cache content and deliver them to users with high performance. Each CDN server has multiple spinning disks that are used for caching content. These disks account for 40-55% ...

Content Delivery Network (CDN) solutions have been progressively integrated to many network infrastructures. However, they show technological limitations when dealing with an increasing number of bandwidth-hungry and demanding applications. One of the ...

This document defines the standard media type used by the Content Delivery Network Interconnection (CDNI) protocol suite, including the registration procedure and recommended usage of the required payload- type parameter.

Since several years, millions of recursive DNS resolvers are-deliberately or not-open to the public. This, however, is counter-intuitive, since the operation of such openly accessible DNS resolvers is necessary in rare cases only. Furthermore, open ...

This paper "peeks under the covers" at the subsystems that provide the basic functionality of a leading content delivery network. Based on our experiences in building one of the largest distributed systems in the world, we illustrate how sophisticated ...

In recent years, adaptive HTTP streaming protocols have become the de-facto standard in the industry for the distribution of live and video-on-demand content over the Internet. This paper presents SmoothCache 2.0, a distributed cache platform for ...

This work proposes a cooperative caching model which supports adaptive bit-rate streaming in content delivery networks. A linear program (LP) problem is applied to maximize the total user satisfaction. The optimal content placement and content fetching ...

This document presents a framework for Content Distribution Network Interconnection (CDNI). The purpose of the framework is to provide an overall picture of the problem space of CDNI and to describe the relationships among the various components ...
