Embodiment approach 1

[0042] According to the first preferred embodiment of the present invention, it also includes:

[0043] The PON chip control module sends the notification message to the OLT switch chip control module, and the OLT switch chip control module determines the switch port corresponding to the line before switching according to the notification message; Check whether the associated service is enabled on the switching port of the switch, and determine whether the associated service of the line before switching is enabled.

[0044] Preferably, when the first method is adopted, the service association module can be integrated with the control module of the OLT switching chip, but not limited to.

[0045] In the database of the OLT switch chip control module, the switch ports corresponding to the current working lines are saved, and then the OLT switch chip control module specifically determines whether the associated service is opened on the switch port by searching for the switch port...

Embodiment approach 2

[0046] According to the second preferred embodiment of the present invention, when the OLT switching chip control module opens the associated service, the PON chip control module also opens the associated service for cooperation; wherein, the service association module specifically determines whether the PON port of the PON chip control module opens the associated service after switching , to determine whether the associated service of the line before switching is enabled.

[0047] Wherein, the PON chip control module also opens associated services to cooperate, specifically refers to the PON chip control module simultaneously opens the associated services of the active and passive lines to cooperate, so that the service associated module can judge whether the PON port of the switched PON chip control module is opened Associated service, determine whether the associated service of the line before switching is enabled. If the associated service is enabled, the control module of...

Embodiment 1

[0054] In this embodiment, the service association module is integrated with the OLT switching chip control module.

[0055] Such as Figure 4 As shown, the service recovery method after line switching in this embodiment mainly includes the following steps:

[0056] Step 401, the PON chip control module judges that the line switching occurs and then constructs a notification message and sends it to the OLT switch chip control module and the business association module;

[0057] Step 402, the OLT switch chip control module receives and searches for the switch port corresponding to the current working line in its own database according to the notification message;

[0058] Step 403, the service association module judges whether the associated service is enabled on the switching port found in step 402, and if the associated service is enabled, step 404 is performed, otherwise the service is not triggered to send the query message;

[0059] Step 404, triggering the OLT switch ch...

Abstract

The invention discloses a method and a system for restoring service after line switching. The method comprises the following steps: after determining that a line is subjected to line switching, a PON (Passive Optical Network) chip control module constructs a notification message and sends the notification message to a service relevance module; when determining that the relevance service of the line switching is started, the service relevance module triggers an OLT (Optical Line Terminal) exchange chip control module to send a query message to a relevance service user through all exchange ports related to the relevancy service by virtue of the PON chip control module; and the OLT exchange chip control module receives a response message returned by the user receiving the query message, and switches the relevancy service to the exchange port in which the response message is located. By utilizing the method and the system, the service can be restored in time, the time consumption for service restoration is controlled at a millisecond level, and the reliable communication of important service is ensured.

Description

technical field [0001] The present invention relates to the technical field of Passive Optical Network (PON for short), and in particular to a method and system for service recovery after line switching in the Passive Optical Network. Background technique [0002] The access layer network is the basic platform for various services. In recent years, the rapid development of broadband access services has led to a continuous growth in the demand for data bandwidth at the access layer. Optical fiber is the best medium for high-speed transmission, large capacity, and multi-service support, making optical fiber access a development direction of the access network. Due to its "passive" characteristics, the passive optical network PON technology, that is, the optical distribution network (Optical Distribution Network, ODN) is composed of passive optical devices such as passive optical splitters and optical fibers, excluding any active devices. As well as the advantages of "point-to...
