The topic is typically not on top of people's minds, yet communication availability forms the foundation of many of our services. SCION can increase the availability of communication on a public network to approximate a private line (leased line) between the communicating parties, even in the presence of active attackers. How can SCION do that?

We have been surprised to already see so many different paths in the nascent SCION network: measuring from the @ETH Zรผrich network to several destinations in the SCION networks, the graph plots each bar to represent the number of paths to a certain destination. It is exciting to see over 100 different paths to many destinations, and over 200 paths to 4 destinations! With the growth of the SCION network the number of paths will further increase! Having dozens of different paths to a destination enables exciting optimizations that are not possible in our single-path Internet: Such as optimizing latency, bandwidth, packet loss, or CO2! Go SCION! #SCiON_Network #SCiON_Internet_Architecture #networksecurity @NetSec_ETH
