2. Status Report GISC New Delhi
GISC New Delhi is connected to the internet via two ISPs, each having bandwidth of 150 Mbps. It gets data feed from RTH New Delhi (a DCPC) having its DRC (mirror site) at a geographically displaced location (Pune) about 1200 Kms away from New Delhi. It is also connected to RMDCN (6 Mbps). Connectivity for GISC – GISC traffic is given in the next slide.

TERMINOLOGY
MEANING
Direct Connection
: The main network to transmit data/product to other GISCs directly. (not backup, not WIS metadata)
managed network
: RMDCN or dedicated circuit or other MPLS network.
bandwidth
: The contract network speed at your centre, to connect to other GISCs through the "managed network".
allocated for WMO
: Reserved bandwidth for WMO data exchange (e.g. by Bandwidth Control Device, PacketShaper etc.)

5. Area of Responsibility
There are four NCs under Area of Responsibility of GISC New Delhi:
NMC Dhaka
NMC Thimpu
NMC Colombo
NMC Maldives

6. AMDCN connectivity
GISC New Delhi, as a primary GISC, is connected via Internet to all the above four NCs. In Total, RTH New Delhi (DCPC) is connected to 18 countries (including NCs and DCPCs) for Global data/ product exchange. These countries are connected via RMDCN (6 countries), 64 Kbps leased line (DKA, KRC, BKK) and internet (10 countries). New Delhi-Bangkok/ Karachi/ Dhaka links have also been configured as VPN tunnel over internet (as redundant links). There is a plan to switch over from RMDCN link through bi-lateral agreement with remaining centers.

7. DCs WIS Compliance
Followings are approved WIS Centres as WIS compliance:
GISC New Delhi
Two DCPCs:
i) RTH New Delhi
ii) RSMC Tropical Cyclones New Delhi.

8. Training – Capacity Building Activity
GISC New Delhi provided introductory and operational training on WIS to its staff locally during 2017 and It is planning training for NCs under its AoR to be conducted in 2019.

9. Operational issues in last period
There is plan for New Delhi – Tokyo (ASCII) and New Delhi – Osaka (DRC Tokyo) to change the link from Socket to FTP.
There has been some interruptions for about two days during first week of March 2019 due to technical maintenance issue.
The problem has been rectified on 6th March 2019 and now it is stable.
