ISRO –SPACE VRF THROUGH NKN

• NKN Extended Excellent

Support for Enabling Inter-

Center Communication

through ISRO VRF

• VRF segment hosted across

two service providers

• Ensure smooth transition of

ISRO Centers to High

Speed NKN segment

• Ensures Failover across

service providers

• Ensure non NKN centers to

be part of ISRO Space VRF
