IPLC explained for banks

The short answer
An IPLC (International Private Leased Circuit) is a dedicated, point-to-point circuit between a site in Bangladesh and a site abroad. Unlike internet traffic it is not shared and does not route across the public internet, which is why banks use it for disaster recovery replication, connections to international payment networks and links to regional headquarters.
Think of an IPLC as a private cable between two of your buildings that happens to cross a border. Capacity is fixed and yours alone, latency is predictable, and the traffic never touches the public internet. It is delivered by carriers that hold international licences: in Bangladesh, an ITC licence for terrestrial routes and rights on submarine systems for subsea routes.
| IPLC | VPN over internet | |
|---|---|---|
| Path | Dedicated, fixed | Shared, varies |
| Capacity | Guaranteed | Best effort |
| Latency | Stable | Variable with congestion |
| Best for | DR, payment networks, HQ links | Branch access, low-volume links |
Most banks run both: IPLC for the links that cannot vary, internet VPN for everything else.
