Embodiment Construction

[0036] The scheme of the present invention comprises:

[0037] 1. Device configuration synchronization

[0038] Both OLT-1 and OLT-2 have allocated hardware resources such as queues for a certain ONU in advance. When the ONU is switched between the two OLTs, the OLT does not need to allocate hardware resources such as queues for the ONU urgently;

[0039] 2. Network management configuration synchronization

[0040] On the network management, the configuration issued by the user to the ONU on the current active OLT is synchronized to another OLT in advance. When the ONU is switched between the two OLTs, the ONU can obtain the configuration issued by the user as soon as possible;

[0041] 3. ONU protection switching

[0042] Update the state of the ONU on the two OLTs, and complete specific execution actions related to protection switching.

[0043] The present invention will be described in further detail below in conjunction with the accompanying drawings.

Abstract

The invention provides a full-protection quick switching method of an Ethernet passive optical network (EPON) system with a hand-in-hand structure. The method comprises the following steps of: performing equipment configuration synchronization of an optical network unit between a first optical line terminal and a second optical line terminal; performing network manager configuration synchronization of the optical network unit between the first optical line terminal and the second optical line terminal; and when a switching mechanism is triggered, switching the optical network unit from the current optical line terminal to the other optical line terminal through the switching mechanism. The full-protection quick switching method of the EPON system with the hand-in-hand structure can be widely applied to an EPON, and the stability of the EPON is improved.

Description

[0001] technical field [0002] The present invention mainly relates to EPON (Ethernet Passive Optical Network) systems. technical background [0003] On May 21, 2009, the State Grid Corporation of China announced the development plan of the "smart grid" to the public for the first time, and initially disclosed its construction schedule, and will fully build a unified "strong smart grid" in 2020. [0004] The overall requirements for smart grid communication access are: strong and reliable, cost-effective, clean and environmentally friendly, transparent and open, and friendly interaction, which puts forward very high requirements for equipment, networking, functions, security, scalability, network management, operation and maintenance, etc. . [0005] Power applications have high requirements for safety and reliability. The hand-in-hand networking function can fully meet the requirements of power hand-in-hand networking, but fast switching must be achieved, and the protecti...
