TEIN General Operation Updates (Aug 2017 – Feb 2018) • • TEIN Topology Major Operation Issues Trouble Ticket Statistics Link Availability Link Utilization Peering Status New Advanced Service ?

TEIN Topology (~ 25 Mar 2018) SG-AF STM-1 (Afg. REN) (new link) AU-PER 10 GE (AARNet) (link upgrade)

Major Operation Issues • • Brought up SG-AF 155 M link AARNet upgraded AU-PER link from 2. 5 G to 10 G Removed TEIN MB MX 80 router (returned to NKN) Restored the connectivity to TEIN MB Po. P via NKN backbone Migrated SG-LON 10 GE link from SMW 4 to SMW 5 submarine cable system Established L 2 VPN between Afg. REN and GEANT Brought up LHCONE VRF peering with KREONET Brought up LHCONE VRF peering with JGN

Peering Status (~ 25 Mar 2018)

New Advanced Service ? • DDo. S Mitigation – Observation • Good news – No DDo. S attack detected on TEIN backbone so far – No DDo. S attack reported from NRENs so far – Compared to commodity backbone, R&E backbone is supposed to have less exposure and attraction to DDo. S attack • BUT – TEIN backbone with limited bandwidth might be more sensitive to DDo. S attack – Limited resource on cyber security might imply more vulnerability and lack of effective defense method – Options • Traffic scrubbing: almost impossible due to high cost • BGP Flowspec can be considered when necessary and applicable
