Abstract:
This article investigates the availability of applications servers running on the NorNet Core test-bed. NorNet Core is the world's first, open, large-scale Internet test-bed for multi-homed systems and applications. Particularly, it is currently used for research on topics like multi-path transport and resilience. The NorNet Core test-bed provides access to worldwide distributed nodes, connected with multiple interfaces over a set of ISPs (Internet Service Providers), providing independent transport paths between them. Each node has a set of programmable nodes that can be used for network experiments. The objective of this paper is to describe a practical approach to assess how suitable this test-bed is for distributed computing, and application servers. In conclusion, the approach taken in this paper shows that by using a simple client to check all communication links, and then create plots of the data, one can observe changes over time, due to network failures, or changes to the network between the sites.
