They have separated the tasks into 2:
- Quantitative analysis on PingER data
- They want to know how PingER has grown, since 1998 until today and how it might be in the next years. By doing this, we may focus on more suitable technologies that deal with scenarios that have a similar profile with PingER.
- Two students are working on this.

- Approaches to handle PingER current data
- Conventional approach – Utilization of Cassandra as back-end database to provide easy crossing of parameters to get PingER data.
- One student is working on this.
- Distributed and parallel approach – Utilization of a data warehouse on top of a distributed file system to provide low latency response to complex queries (like the ones we were not able to do on my previous work). Additionally, how Scientific Workflow Management Systems may help in the ETL process of transforming PingER so it can easily be stored on the data warehouse.
- Renan is working on this.
- Pure RDF approach – Good ways of modeling and natively storing RDF data.
- Maria-Luiza is working on this.
- NoSQL approaches – How other NoSQL DBMS may be adequate for PingER multidimensional data.
- Two students are evaluating existing NoSQL solutions for multidimensional scenarios (such as PingER)
- Key-Value storages for PingER data in RDF
- This is Ibrahim’s work.
- Conventional approach – Utilization of Cassandra as back-end database to provide easy crossing of parameters to get PingER data.
In the end, they want to compare all these approaches.

The ping server at http://pinger.fsktm.um.edu.my/cgi-bin/traceroute.pl?target=www.slac.stanford.edu&function=ping gives ping server busy at the moment. Please try again later. Some one with access to the web servers should look at that (e.g. review the web logs). Maybe it is being hit with a lot of requests simultaneously. If they are coming from SLAC we may want to look at reflector.cgi.
