Abstract

Embodiments of the present invention provide an optical transport network (OTN) network architecture and a scheduling method. The network architecture method includes: a main dispatching ring, at least two groups of networking, and user access equipment; wherein, the networking includes service downloading equipment sequentially connected by communication, at least two levels of cascaded convergence rings, and access rings; The user access device is connected to the service downloading device via the access ring and convergence ring in sequence, or is connected to the service downloading device via the access ring, convergence ring and main dispatching ring in sequence ; Wherein, the main dispatching ring is used to control the aggregation ring where the user access device is located and the target service downloading device when the target service downloading device of the user access device is a service downloading device of the same network The routes between them are enabled. The embodiments of the present invention solve the problem that the network architecture of the transmission network in the prior art is difficult to adapt to the increasing demand for broadband.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of mobile communications, and in particular to an OTN network architecture and a scheduling method for an optical transport network. Background technique [0002] With the development of mobile communication technology, the acceleration of broadband services poses a great challenge to the existing transmission network. The process of uplinking the optical line terminal (OLT) equipment of the passive optical access system (Gigabit-Capable PON, GPON) of the broadband service to the broadband remote access server (Broadband Remote Access Server, BRAS) mainly uses packet Transport network (Packet Transport Network, PTN), optical transport network (Optical Transport Network, OTN) or bare fiber for carrying; at present, OTN is only deployed at the backbone aggregation layer, and only carries OLT services on PTN and a small number of backbone aggregation points. For example, OLT services such...
