Saqib submitted the Camera ready paper on “A Blockchain-based Decentralized Data Storage and Access Framework for PingER” and it has been accepted in Trustcom2018.
Two previously accepted papers are now online on the following links.
- The paper titled “Detecting Anomalies from End-to-end Internet Performance Measurements ( PingER ) using Cluster-Based Local Outlier Factor” is online on IEEE portal. https://ieeexplore.ieee.org/document/8367380/ . This paper is not available in SLAC repository. Les will follow up.
- The paper titled “Internet Performance Analysis of South Asian Countries using End-to-End Internet Performance Measurements” is online on IEEE portal. https://ieeexplore.ieee.org/document/8367431/ . This paperis available in SLAC repository (http://www.slac.stanford.edu/pubs/slacpubs/17000/slac-pub-17205.pdf). However, without doi no and other necessary details. Les will follow up.
IPv6 node in Beijing is up and running for the last 3 7 weeks but not available from outside China. Does this host have a name or what is its Iv6 Address (is the latter 2001:da8:270:2018:f816:3eff:fef3:bdf3)? Is it possible to make it accessible from say SLAC (134.79.0.0/16)? Is there an update?outside China. It does not appear possible to make the host accessible outside China. We are looking at alternates (e.g. pushing the data from Beijing to SLAC).
Discussion item
Saqib sent an Saqib sent email to the team:
in In early years of PingER, the framework was was designed to check check the latency and other Internet performance metrics between CERN and SLAC to facilitate the data transfer between the two sites.
Discussion item
Saqib sent an email:
I am thinking, is there any possibility to use PingER to monitor the health of the Bitcoin blockchain network? Since the latency is critical in Bitcoin blockchain network as all the incentives depend on the propagation of transactions and mined blocks. Thus, I am only interested in measuring the latency to check its effect on the propagation of the transactions and mined block among different mining pools. I think if we can do such thing on a historical basis as PingER already does for the Internet, it will increase the worth of the framework and its usability.
Maybe a few test experiments can guide us to a good research paper. I am not sure about the feasibility idea, therefore, need your kind feedback
