About
Today's research often relies on a high volume of data. While universities cannot always provide the computing resources to process a given amount of data, a high-performance com- puting cluster (HPCC) offers a cost-effective alternative for re - searchers. With a SCION-based Science DMZ, the HPCC and each univer- sity operate as independent autonomous system (AS), manag- ing their own cryptographic keys and enforcing their own net- work rules. Each AS also has its own LightningFilter deployed. High-volume data transfers between a university and the HPCC are performed using dedicated, SCION-based systems, such as Hercules, which route their traffic through Lightning- Filter instead of the network's general-purpose firewall. With LightningFilter, the ASes can control the amount of traf- fic received from the other ASes or from specific hosts. For instance, the HPCC can enforce different rate limits for each university while guaranteeing a certain throughput for specific hosts. Such limits are important to protect the servic- es offered from misbehaving hosts that consume more band- width than agreed and thus partially or completely block oth- er hosts from reaching the service.
We will present the latest developments on SCION based ScienceDMZ and showcase some early deployments and PoCs..
