Multi-operator ODN sharing and heterogeneous PON unified management method

Abstract

The invention discloses a multi-operator ODN sharing and heterogeneous PON unified management method. The method comprises the following steps: 1, a soft defined virtual passive optical network overall system framework, that is, providing an open control interface in a PON access network to implement a programmable intelligence management and control platform, dividing resources into multiple slices virtually and flexibly, and independently forwarding the slices by operators in respective virtual resource channels; 2, components of a virtual passive optical network system; 3, a virtual passiveoptical network configuration working mechanism; 4, a sharing PON equipment increases software-defined identifiers of telecom operators; 5, a multi-operator sharing work configuration mechanism; 6, adata forwarding mechanism; 7, a system management; 8, pool grouping; 9, virtual network topology; 10, QoS implementation; 11, the realization of security assurance and coexistence transition; 12, therealization of energy-saving mechanism; and 13, collaborative management with the upper-level network. The multi-operator ODN sharing and heterogeneous PON unified management method has the advantages of realizing the indiscriminate opening of the service level and reducing the construction cost of the resident network.

Description

technical field [0001] The invention relates to the technical field of communication networks, in particular to a multi-operator ODN sharing and heterogeneous PON unified management method. Background technique [0002] The PON (Passive Optical Network, Passive Optical Network) system consists of OLT, ONU and ODN. Among them, the OLT (Optical Line Terminal, optical line terminal) is located at the central office, and is the core component of the entire PON system. For the multi-point PON interface, data is sent to each ONU (Optical Network Unit, Optical Network Unit) in broadcast mode. ODN (Optical Distribution Network, optical distribution network) is an optical distribution network composed of POS (Passive Optical Splitter, passive optical splitter), so that the optical fiber transmission bandwidth of a PON interface can be shared by multiple ONUs. The ONU is located at the user end and realizes the access of multiple services such as data and voice. [0003] The techni...

AI Technical Summary

Problems solved by technology

[0006] 1. When the user opens the service, it is necessary to jump the optical fiber between the operator and the public optical distribution box every time. The implementation is complicated and error-prone. safety factor, poor reliability

[0007] 2. Resource allocation is inflexible, especially the scale and specifications of resources such as optical cables and optical distribution facilities on the operator’s side in the initial stage are difficult to predict, prone to repeated construction or waste, and low resource utilization

[0008] 3. The management of the network is complex, lacks flexibility, and it is difficult to locate faults and maintain low efficiency

[0009] 4. Multiple PON technologies are applied in the network at the same time, and there is a lack of flexible heterogeneous network resource scheduling mechanism; the current optical access network includes EPON, GPON, 10G EPON, 10G GPON, WDM-PON, P2P-PON and other technologies, different networks They are not compatible with each other, the network resource management and control mechanisms are independent of each other, and there is a lack of flexible heterogeneous network source scheduling mechanism. The management and distribution of services can only be operated on their respective network management platforms, and the efficiency is low.
