Several years ago, service providers embarked on migration strategies to move away from circuit switched networks, in favour of packet based transport networks. Consequently, improvements in operational expenditure have already been achieved and adoption of packet transport technology continues to flourish. This course is designed to provide a thorough understanding of the packet transport network concept, exploring the associated driving factors, challenges and technologies being deployed.
Who Should Attend?
This technical course is designed for any personnel with a vested interest in the trends taking place in packet transport technology, ranging from the network engineers on the ground, to the strategic planners looking for further options to improve the network.
