Virtual Private Network
A virtual private network (VPN) uses public telecommunication infrastructure, such as the internet, to securely connect remote sites/ users to the organisation’s network. These services cost less than alternatives, such as, traditional leased lines or remote access servers. VPN technology is based on the tunnelling concept, which involves establishing and maintaining a logical network connection. In such a type of connection, packets constructed in a specific VPN protocol format are encapsulated within another base or carrier protocol, and then are transmitted between the VPN client and server, and finally de-encapsulated on the receiving end.
To provide traffic isolation and differentiation without substantial overheads, multi-protocol label switching (MPLS) is among the commonly used methods to create VPNs. MPLS-VPN technology allows service providers complete control over parameters that are critical to offering customers service guarantees with regard to bandwidth throughputs, latencies and availability. It reduces network complexity and cost for the customer, and eliminates the need for an in-house technical workforce. Rather than setting up and managing individual point-to-point circuits between each office using a pair of leased lines, MPLS-VPN customers need to provide only one connection from their office router to a service provider.
RailTel offers its MPLS based VPN services to enterprise customers including small and medium enterprises, educational institutions and banks and financial institutions primarily aimed at enhancing their business performance.
Currently, IT/ITeS companies use VPN primarily to connect offices across locations. Increase in automation and utilisation of artificial intelligence, and demand for higher VPN bandwidths, are expected to drive revenue from the IT/ITeS segment, going forward. Moreover, legacy IPLCs are being replaced by global MPLS or international MPLS, which is also expected to provide growth opportunities to the VPN segment.
