Optical Transport Networks (OTN)

Networking software RSVP-TE (ReSerVation Protocol) IP Routing OTN (Optical Transport Network)

Operators of carrier and service provider networks are always under immense pressure to reduce operational and capital expenditures. As if that pressure weren't enough, they must also contend with preserving legacy technologies while addressing the continuous shift in traffic type (most notable: the shift from circuit to packet traffic). The ITU's Optical Transport Network (OTN) recommendation provides a network-wide framework that truly delivers on the carrier requirements for reduced costs, greater flexibility, and increased efficiencies.

What is Optical Transport Network (OTN)?

Networking software MPLS (Multi-Protocol Label Switching) OTN (Optical Transport Network)

The ITU's Optical Transport Network (OTN), as defined by recommendation G.709, provides a network-wide framework that adds SONET/SDH-like features to WDM equipment (also known as Wavelength Switched Optical Network equipment, or WSON equipment). It creates a transparent, hierarchical network designed for use on both WDM/WSON devices and TDM devices. Two switching layers are formed (TDM and WSON) and functions of transport, multiplexing, routing, management, supervision, and survivability are defined.
