Update on CONUS Networks

CONUS Networks, including ESnet:

The IDF was selected, it is Google. There is an official announcement about it. PoC did it by KT, some infrastructure will be left to leverage the IDF. KT will continue doing tests.

Cristián Silva will find the report of the PoC and distribute it to the LHN-NET

Jeronimo Bezerra MTU was set to a very low value, might be only necessary for the test and not necessary for the future. Cristián Silva to confirm this.

Chilean/International Networks Update

Developments in La Serena and end-to-end service to NCSA for upcoming Auxiliary Telescope Traffic and general (internet, mail, voice) traffic:

Cisco ACI review took place during September, the recommendation is to change to NX-OS. This only affects the LAN and not the LHN

Base only essential work, Summit starting and could be finished next week.

40G backup link can not be done yet, AURA does not classify this activity as essential, there are frequent outages in the main link due to social unrest, so this activity is becoming more needed. 

Jeronimo Bezerra Stgo - Bs Aires link is ready, provided by Silica. By end of this month, Bs Aires - Porto Alegre segment (CenturyLink) should be in.
