The READY distributed research environment address the increasingly problematic latency issues of the Internet. The scientific objectives include analysing and understanding the causes for latency, developing new mechanisms, protocols and architectural elements to mitigate the latency problem, and evaluating the results in application-relevant scenarios using testbeds, simulators and other tools.
Research and development in the Internet infrastructure area have for a long time focused on increasing network throughput and the utilisation of network resources. Networking equipment, protocols, architectures and end-systems have been tuned to increase the performance of applications transferring large amounts of data. This has, however, resulted in a network with large buffers that increase the delivery time of individual packets, and thus result in large latencies for interactive and transaction-based applications.
Latency in the Internet infrastructure is an increasing problem for many Internet applications and services. Interactive services are disrupted for shorter or longer periods of time. It thus becomes hard to deliver media services with low latency. Web services suffer from long delays for each transaction which is frustrating for the end user because of the long waiting time and bad interactivity.
