Data transfer graph between NKN (India's NREN) and NORDUnet (NREN for Nordic countries) https://stats.nordu.net/stat-q/r-all?q=all&name=NKN. Low data transfer between the two though.

Peering seems to be via Netherlight (https://www.surf.nl/en/services/network-connectivity/netherlight) in Amsterdam from https://nordu.net/nkn-india-and-nordunet-set-direct-peering/ (2017).

Latest LHCONE map from https://indico.cern.ch/event/772031/contributions/3442737/attachments/1853717/3047028/Interpreting_the_LHCONE_Map_LHCONE_Umea_Sweden_June_2019.v4.pdf (page 2).

NKN India (tier 2 site at VECC-SINP campus in Kolkata) and TIFR India connections can be seen on bottom left corner.

Data transfer graph between NKN (India's NREN) and CERN (birthplace of www and operators of Large Hadron Collider) https://monit-grafana-open.cern.ch/d/XoND3VQ4k/nkn?orgId=16&from=now-24h&to=now&timezone=browser&var-source=raw&var-bin=5m

Transfer rates are almost same as between GEANT-NKN as essentially they're the same link. NKN/TIFR participate in LHCONE (India has two tier 2 sites) which carries LHC data over these links for scientific research purposes.

Public Graphana of transfer between NKN (India's NREN) and GEANT (essentially EU NREN backbone) https://public-brian.geant.org/d/ZyVgYFgVk/nkn?orgId=5&from=now-30d&to=now.

Transfer on both side usually seems to be averaging around 600 Mbps (lower than I expected).

From https://web.archive.org/web/20211010081515/https://www.geant.org/News_and_Events/Pages/New-NKN-international-network-to-boost-EU-India-collaboration.aspx published in 2016, NKN seems to have 2x10 Gbps capacity towards GEANT.

NKN has joined NIXI DEL and BOM https://bgp.tools/as/9885#ix \o/

First getting new upstreams and now finally joining IXes. Long overdue changes but I'm elated.

AS9885 NKN INTERNET GATEWAY NETWORK - bgp.tools

NKN INTERNET GATEWAY NETWORK (AS9885) is an 15 year old BGP network that is peering with 32 other networks and has 4 upstream carriers

sahilisterMay 30, 2025

Seeing NKN/AS9885 (NREN from India, also upstream for NIC India) IP ranges getting announced from Airtel/AS9498 in addition to earlier only via Reliance Jio/AS55836

Net positive though, I would say.
