Network dimensioning methodology in packet-optical transport network

Abstract

Packet-Optical Transport Network (POTN) technologies and architectures integrate the functional switching capability of WDM wavelengths, Ethernet via various protocols, OTN/ODU as well as TDM. From a telecommunication service provider's view, it is a great advantage to replace various multiple-layer network equipment with the unified equipment using POTN technologies. On the other hand, it is a drawback to increase the complexity to operate highly-integrated equipment and to manage the network fluently. In this paper, we investigate considerations for dimensioning POTN and then we design the POTN Dimensioning System to reduce our operation and configuration complexities. Finally we suggest the result of network capacity in POTN through a test network dimensioning.
