A comparative analysis of MPLS, MLLN and ISDN

When talking about telecommunication, we hear a lot about leased lines, ISDN and MPLS.

This article makes a comparative analysis among MPLS, MLLN and VPN. The following table captures the differences.



Network Management Systems: The network management systems allows the network operator to configure, manage and monitor all aspects and parameters of the remote elements of the MLLN without the need for local intervention

Digital Cross Connect Systems: A piece of circuit switched network equipment used in telecommunications networks that allow lower level TDM (Time-division Multiplexing) bit streams to be rearranged and interconnected among higher level TDM signals.

Multiplexing: It is a process where multiple analog message signals or digital data streams are combined into one signal over a shared medium to share an expensive resource. The multiplexed signal is transmitted over a communication channel, which may be a physical transmission medium. A reverse process, known as demultiplexing, can extract the original channels on the receiver side. A device that performs the multiplexing is called a multiplexer (MUX), and a device that performs the reverse process is called a demultiplexer (DEMUX).

Time Division Multiplexing: It is a type of multiplexing in which two or more signals are transferred simultaneously as sub channels in one communication channel, each signal taking turns based on a fixed time slot.

Network Terminating Units: A unit of the network which serves as an interface between customer equipment and digital data service.
