The migration from ATM/SDH transport technology to IP/Ethernet based technologies is now happening on a broad scale, worldwide. Including migration of mobile backhaul transmissions. The main drivers for this evolution is the promised cost efficiency through convergence of multiple service networks, into a single multiservice transmission network.
However, a multiservice transmission network should meet the –diverse- requirements from multiple services, both real time and non-real time such. That puts a number of QoS related requirements on the new transport infrastructure.
The course presents the relevant transport network architectures from ‘last mile’ backhaul transmission to the gigabit backbone core transmission. The combinations of MPLS/IP/Ethernet over radio links, copper and fibre transmission media are explored and exemplified. Additional focus is given to traffic separation and prioritization mechanisms in IP transport networks. The requirements from various traffic types (real time VoIP, internet browsing, IPTV, video streaming, signalling etc.) are presented and mapped onto MPLS/IP and Ethernet levels and their service classifications.
