These models address large-scaled switched optical networks that would typically contain both data-centric network equipment (IP routers) and transport-centric equipment (OTN-based WDM transport
A comparison of OTN interfaces OTU1, OTU2, OTU3, and OTU4, outlining their specifications and differences in line rate, payload rate, and application.
InfiniBand has no specific standard application programming interface (API). The standard only lists a set of verbs such as ibv_open_device or ibv_post_send,
An optical transport network (OTN) is a digital wrapper that encapsulates frames of data, to allow multiple data sources to be sent on the same channel. This creates an optical virtual private network for each client signal. ITU-T defines an optical transport network as a set of optical network elements (ONE) connected by optical fiber links, able to provide functionality of transport, multiplexing
