Classic Tech operates a scalable and secured network that employs Virtual Private LAN Service (VPLS) over a Multi-protocol Label Switching (MPLS) platform.Classic Tech has deployed metro fiber route mile infrastructure over which it offers Ethernet services at speeds up to 1 Gbps.


Classic Tech has MPLS as its core backbone for the Internet and intranet connectivity. MPLS is the fastest switching technology, which is typically run by ISP/NSPs for the faster packet switching process. MPLS enables Network Service Providers to offer various kinds of services to the enterprises. There can be multiple options for MPLS circuit that an enterprise can own for the intranet connectivity. Classic Tech has been expanding its redundant and reliable services throughout the country with the most popular vendor platforms like Cisco, Juniper and MikroTik for the uninterrupted services to the enterprises. The protocols used inside the cloud has capability of handling thousands of customer routes and the customers can run any addressing hierarchy as per the necessity regardless of what other customers are using as their Layer three circuit addressing.

Likewise, Classic Tech has adopted MPLS architecture due to its ability to provide multiple kinds of cost effective services that can be offered to the customers who are willing to expand their branches all over the country with redundancy and reliability.



MPLS Layer 3 VPNs use a peer-to-peer model that uses Border Gateway Protocol (BGP) to distribute VPN-related information. This highly scalable, peer-to-peer model allows enterprise subscribers to outsource routing information to service providers, resulting in significant cost savings and a reduction in operational complexity for enterprises. Service providers can then offer value-added services like Quality of Service (QoS) and Traffic Engineering, allowing network convergence that encompasses voice, video, and data. IP-based VPNs use the next-generation Virtual Routing/Forwarding instance (VRF)-Lite, called Easy Virtual Network (EVN). This simplifies Layer 3 network virtualization and allows customers to easily provide traffic separation and path isolation on a shared network infrastructure, removing the need to deploy MPLS in the enterprise network. EVN is fully integrated with traditional MPLS-VPN or MPLS VPNomGRE.



Layer 2 VPN (L2VPN) emulates the behavior of a LAN across an IP or MPLS-enabled IP network allowing Ethernet devices to communicate with each other as they would when connected to a common LAN segment. As Internet service providers (ISPs) look to replace their Asynchronous Transfer Mode (ATM) infrastructures with an IP infrastructure, there is a need for to provide standard methods of using an IP infrastructure to provide a serviceable L2 interface to customers; specifically, to provide standard ways of using an IP infrastructure to provide virtual circuits between pairs of customer sites.
Building a L2VPN system requires coordination between the ISP and the customer. The ISP provides L2 connectivity; the customer builds a network using data link resources obtained from the ISP. In an L2VPN service, the ISP does not require information about a customer’s network topology, policies, routing information,point-to-point links, or network point-to-point links from other ISPs.

The ISP requires provider edge (PE) routers with the following capabilities:

  • Encapsulation of L2 protocol data units (PDU) into Layer 3 (L3) packets.
  • Interconnection of any-to-any L2 transports.
  • Emulation of L2 quality-of-service (QoS) over a packet switch network.
  • Ease of configuration of the L2 service.
  • Support for different types of tunneling mechanisms (MPLS, L2TPv3, IPSec, GRE, and others).
  • L2VPN process databases include all information related to circuits and their connections.
