Problems solved by technology

Although the method in this case can realize the backup of the link between the optical splitter and the OUN, it needs to use a special ONU (that is, an ONU with two PON ports), and one ONU will occupy the PON interfaces on two OLTs , due to the limited number of PON interfaces on the OLT, this method will greatly reduce the number of ONUs actually connected to the OLT

Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] The method provided by the present invention mainly includes: connecting a user network port (UNI) of ONU1 with a UNI of ONU2, wherein both OUN1 and ONU2 are single PON port devices; ONU1 is used to connect the UNI of ONU2 and the PON port on ONU1 Configured as the Smart Link protocol group under the same VLAN, the UNI on ONU2 used to connect to ONU1 and the PON port on ONU2 are respectively configured as the uplink in the Monitor Link protocol group under the VLAN. port and downstream port. ONU1 forwards service traffic through a port in an Active state, and ONU2 forwards service traffic through a port in an UP state.

[0024] The networking involved in the above-mentioned method of the present invention can be as follows image 3 or F...

Abstract

The invention provides a method and a system for improving the reliability of a service in a passive optical network (PON) system. User network interfaces (UNI) of two optical network units (ONU) are connected, a flexible link protocol group and a monitoring link protocol group are configured on the two ONUs respectively, and the mutual backup of the two ONUs is realized in a way of fitting special mechanisms of the flexible link protocol group and the monitoring link protocol group. By the method and the system, link backup protection between optical line terminals (OLT) and the ONUs can be realized by adopting ordinary single-PON port ONUs, and the number of actual accessing ONUs under the OLT is not influenced.

Description

technical field [0001] The invention relates to optical network communication technology, in particular to a method and system for improving service reliability in a passive optical network system. Background technique [0002] The rise of the Internet, especially the development of multimedia services, has led to an increasing demand for broadband. Optical fiber-based access technology has the advantages of high bandwidth, strong long-distance transmission capability, good confidentiality, and strong anti-interference ability, and can meet the current and future business development requirements for bandwidth. Among various optical fiber access technologies, Passive Optical Network (PON) has become a leader in optical access technology due to its advantages such as easy maintenance, high bandwidth, and low cost. [0003] With the extensive application of PON systems, carrier-class reliability becomes very important, and access systems are no exception. The point-to-multip...
