 | Transport networks are continuously evolving. The current trends towards fixed-mobile convergence, packet-based services and rapidly increasing traffic – but slowly rising revenues – are forcing operators to leverage the best of available options in each layer in order to minimize capital expenditure and especially operational expenditure. There are clear roles for each layer in the packet network; “all-IP” networks need a lot more than just IP. |
While next-generation synchronous digital hierarchy (NG-SDH) retains a key role, the latest generation of Packet Optical Transport Platforms is integrating cost effective wavelength switching, extended reach optics, connection-oriented packet standards and optical transport network/optical data units (OTN/ODU) networking. The great diversity of network contexts results in there being no single solution that is optimum for all cases. This paper describes the main options and their selection criteria.
