LINKdotNET multi-service PDN (Public Data Network) is a next-generation network that supports multiple services and deploys MPLS technology within its core network to achieve Quality of Service (QoS), high throughput, reliability and availability.

LINKdotNET PDN consists of three centralized fully redundant carrier class IP backbone Gigabit routers that are connected to each other using multiple STM1 connections to provide redundancy and load balancing over the core network. Core routers handle pure labeled IP packets providing very low latency and processing. The core network is built on Juniper Internet routers.

The second layer (distribution layer) of the network adds more MPLS LSR, using Gigabit routers, to the network. The LSR functions as a distribution layer that distributes traffic flow across the network. As an aggregation node, each feeds traffic to several POPs (access layer). This intermediate layer has a very important role also in terms of load balancing and redundancy and off loads the core layer to allow dedication to the core function. Distribution LSRs are connected to the three core nodes using multiple of E1s, E3s to guarantee redundancy.

At the access layer, which is the third layer, XDSL technology is implemented to offer different types of XDSL technology for both corporate and residential customers. In addition, there are dial-up access servers that offer dial-up connections using highest speed access technology V.90 served by other connectivity techniques like VPN tunneling and IPSec.
