The Open High Throughput Computing Content Delivery Network

Mechanisms for High Throughput Computing

For many experimental scientists, scienti c progress and quality of research are strongly linked to computing throughput. In other words, most scientists are concerned with how many oating point operations per week or per month they can extract from their computing environment rather than the number of such operations the environment can provide them per second or minute. Floating point operati...

Cluster Computing: High-Performance, High-Availability, and High-Throughput Processing on a Network of Computers

Globally distributed content delivery - Internet Computing, IEEE

As Web sites become popular, they’re increasingly vulnerable to the flash crowd problem, in which request load overwhelms some aspect of the site’s infrastructure, such as the frontend Web server, network equipment, or bandwidth, or (in more advanced sites) the back-end transaction-processing infrastructure. The resulting overload can crash a site or cause unusually high response times — both o...

ActiveCDN: Cloud Computing Meets Content Delivery Networks

Content delivery networks play a crucial role in today’s Internet. They serve a large portion of the multimedia on the Internet and solve problems of scalability and indirectly network congestion (at a price). However, most content delivery networks rely on a statically deployed configuration of nodes and network topology that makes it hard to grow and scale dynamically. We present ActiveCDN, a...

Architecture for Open Content Delivery Networks

We describe a new architecture for an open Content Delivery Network (CDN) built from a single software component, Request-Redirector, collocated with the web server. The Request-Redirector encapsulates all the functions that a CDN requires. In particular, a mechanism to redirect client requests to edgeservers; a local network proximity database used to select the best edge-server; and a mechani...
