Globule: a collaborative content delivery network

G. Pierre, M. van Steen
2006 IEEE Communications Magazine  
We discuss the issues involved in developing and setting up a large-scale collaborative CDN and provide solutions for many of its unique problems.  ...  We present Globule, a collaborative content delivery network developed by our research group.  ...  Replicating static content, even in the presence of updates, is relatively simple. On the other hand, a large amount of Web content is generated dynamically.  ...

Replication Based on Objects Load under a Content Distribution Network

G. Pallis, K. Stamos, A. Vakali, D. Katsaros, A. Sidiropoulos
2006 22nd International Conference on Data Engineering Workshops (ICDEW'06)  
In this direction, crucial data management issues should be addressed. A very important issue is the optimal placement of the outsourced content to CDN's servers.  ...  In this framework, Content Distribution Networks (CDNs) are increasingly being used to disseminate data in today's Internet, providing a delicate balance between costs for Web content providers and quality  ...  In this paper, we study the content replication problem, which refers to the issue of optimally replicating the outsourced content in surrogate servers of a CDN.  ...

A Case for Peering of Content Delivery Networks

Rajkumar Buyya, Al-mukaddim Pathan, James Broberg, Zahir Tari
2006 IEEE Distributed Systems Online  
But present trends in content networks and content networking capabilities give rise to the interest in interconnecting content networks.  ...  Moreover, the logical separation between contents and services in this context results in two content networking domains.  ...  In such CDN environment, Web content based on user requests are fetched from the origin server and a user is served with the content from the nearby replicated Web server.  ...

DotSlash: Handling Web Hotspots at Dynamic Content Web Sites

W. Zhao, H. Schulzrinne
2006 Proceedings IEEE INFOCOM 2006. 25TH IEEE International Conference on Computer Communications  
We propose DotSlash, a self-configuring and scalable rescue system, for handling web hotspots at dynamic content web sites.  ...  To support load migration for dynamic content, an origin web server sets up needed rescue servers drafted from other web sites on the fly, and those rescue servers retrieve the scripts dynamically from  ...  By supporting dynamic script replication, DotSlash can completely remove the web server bottleneck for dynamic content web sites.  ...

A New Replica Placement Algorithm for Improving the Performance in CDNs

Lei Zhang, Hui Tian, Stephan Steglich
2009 International Journal of Distributed Sensor Networks  
In summary, we study the online problem of placing web replicas in CDNs to minimize the cost for clients to access data replicated from the original web servers.  ...  In response to these challenges, commercial Content Distribution Network (CDN) deploys a set of proxy servers called replicas and improves the content delivery performance by replicating the content to  ...  In summary, we study the online problem of placing web replicas in CDNs to minimize the cost for clients to access data replicated from the original web servers.  ...

Distributed Systems to Support Efficient Adaptation for Ubiquitous Web [chapter]

Claudia Canali, Sara Casolari, Riccardo Lancellotti
2005 Lecture Notes in Computer Science  
Moreover these platforms would even address novel content management issues that are related to the replication and to the consistency and privacy requirements of user/client information.  ...  These novel advanced services will stress the content provider platforms in an unprecedented way with respect to the content delivery seen in the last decade.  ...  We can define three players in the game of content adaptation: the client which issues requests, the content provider which hosts the Web resources being requested and the adaptation provider which is  ...
