Packet Transport Networks

As TDM transmission networks continue to be replaced by packet based transport solutions, this course seeks to explain the key technologies involved. Initially, the course will explore the concepts of IPv4 and IPv6, before then focusing on the operation of MPLS (including its key capabilities and features). Carrier Ethernet is also considered, exploring its standardized services and transport options. Finally, real life use cases for PTN are examined, in conjunction with a consideration of the new challenges that packet networks bring.
