kbit/s leased line by 1992.

12.4.2 ERNET Backbone

ERNET backbone is a sophisticated link of terrestrial and satellite-based wide area networks. The
satellite WAN using VSAT technology. The VSAT network acts as an overlay for the terrestrial
WAN by providing backup links between the backbone sites. International connectivity is achieved
through gateways at New Delhi, Mumbai, Bangalore and Kolkata, with a total capacity of 6.64 Mb.
Daily traffic over ERNET exceeds 20 GB. ERNET architecture is based on industry standard TCP/IP
protocol.
ERNET backbone is being enabled to support IPv6.
ERNET international gateway and PoP sites
The ERNET is supported by the following backbone sites which enable organizations located at
different geographical locations to access various services.
