The optical transport network: building the future of transport

Aricent

The major driver for OTN is the increasing demand for bandwidth from residential and business customers. Residential internet use is rising for a variety of reasons: growing demand for cloud storage of personal information, online gaming, online shopping, staying connected over long distances, social media, video chatting and more.

All of these applications require communications and network service providers to deliver more capacity on their networks.
Communications and network operators—and indirectly network equipment providers (NEPs)—must support all this demand by upgrading their networks and offering new value-added services.

However, existing SDH and SONET solutions are unable to address the challenge of rising bandwidth demand. Therefore, OTN emerges as the solution by using WDM and DWDM to overcome the bandwidth limitations of SDH and SONET, while, at the same time, incorporating key aspects of SDH and SONET to provide determinism and reliability.

As part of its comprehensive portfolio of networking products, Aricent offers a licensable software framework for a variety of OTN network equipment. The Aricent framework provides software for both the network element and the network management system (NMS).
