There are three types of MPLS VPNs deployed in networks :


Point-to-point MPLS VPNs employ VLLs (virtual leased lines) for providing Layer2 point-to-point connectivity. Between two sites. Ethernet, TDM, and ATM frames can be encapsulated within these VLLs.
Some examples of how point-to-point VPNs might be used by utilities include:
encapsulating TDM T1 circuits attached to RTUs
forwarding non-routed DNP3 traffic across the backbone network to the SCADA master controller.

Layer 2 VPN (VPLS):
Layer 2 MPLS VPNs, or VPLS (virtual private LAN service), offers a “switch in the cloud” style VPLS service. VPLS provides the ability to span VLANs between sites. L2 VPNs are typically used to route voice, video, and AMI traffic between substation and data center locations.

Layer 3 VPN (VPRN):

Layer 3, or VPRN (virtual private routed network), utilizes layer 3 VRF (VPN/virtual routing and  forwarding) to segment routing tables for each “customer” utilizing the service. The customer peers with the service provider router and the two exchange routes, which are placed into a routing table specific to the customer. Multiprotocol BGP (MP-BGP) is required in the cloud to utilize the service, which increases complexity of design and  implementation. L3 VPNs are typically not deployed on utility networks due to their complexity; however, a L3 VPN could be used to route traffic between corporate or data center locations.

Airtel SIP Trunks


Bharti Airtel has deployed state of art next generation (NGN) PSTN switches in major cities to provide the IP based solution to its customers. This functionality enables customers to make 2000 simultaneous calls through single link. This solution is based on open standards and supports popular codec likes G 711 & G 729.
