Abstract
Optical transmission network (OTN) is a transmission network which realizes the transmission, multiplexing, routing and monitoring of service signals in the optical domain, and ensures its performance index and survivability. Packet enhanced optical transmission network (PeOTN), as a new generation of optical transmission network technology, takes on the efficient bandwidth of DWDM/OTN technology, saves optical fiber, and smoothly upgrades the network form. It also integrates the open network form of flexible service scheduling, reliable network management and flexible protection mechanism of SDH/MSTP technology. Based on the technical development of optical transmission network, this paper analyzes the new demand of transmission network in service carrying, discusses the related planning scheme and service application mode of packet enhanced optical transmission network equipment construction carrying network, and provides reference basis for the construction of transmission network in communication network.
