Embodiment Construction

[0041] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0042]The link layer discovery protocol LLDP requires that the local device only send its own Layer 2 link information to neighboring devices, and save the Layer 2 link information of neighboring devices on the local device, and then store the Layer 2 link information in the standard simple In the MIBs (Management Information Base) information base of the network management protocol SNMP. The existing LLDP implementation method is applied to the FTTX access system, which will reflect the following technical obstacles:

[0043] 1. If figure 2 In the shown PON (passive optical network) access system, the optical line terminal equipment OLT, the Ethernet switch Ethernet switch, and the computers PC1 and PC2 are all independent network elements. If these devices support the simple network management protocol SNMP, then they are a MIB node. When the network ma...

Abstract

The invention relates to a method for realizing link discovery and management in an FTTX (Fiber to the X) access system. The method comprises the steps of: periodically sending link layer discovery protocol messages to an uplink device of an OLT (Optical Line Terminal) device through an uplink interface by the OLT device; performing a listening task by a core swap disk program of the OLT, wherein the link layer discovery protocol messages from an ONU (Optical Network Unit) and an ONU user-side access device are received in the listening task; respectively storing locally stored information of the device and information of a user-side network device into a local link layer discovery protocol management information base by the OLT device; requiring to send LLDPDU (Link Layer Discovery Protocol Data Unit) protocol messages to the uplink device by the OLT so as to report the existence of the OLT; and carrying out extension of the LLDPDU messages. The invention fills in the gap of application of the traditional link layer discovery protocol (LLDP) and provides the method for realizing link layer discovery in the FTTX access system with optical path grading, especially on a plug-in card type OLT device; and according to the method, provided by the invention, the basic architecture of the FTTX access system is not affected, and the operation is simple and easy to realize.

Description

technical field [0001] The invention relates to the field of FTTX (optical fiber access) access systems, in particular to a method for realizing link discovery and management in the FTTX access system. Especially for central office and remote equipment management and topology analysis in FTTX access system, especially link discovery and management methods. Background technique [0002] LLDP (Link Layer Discovery Protocol) is a Layer 2 discovery protocol defined in IEEE 802.1ab. The protocol stipulates that each interface of the device stores the status information of the device, and the device can send the status information of the device to its neighbor nodes. When needed, the interface can also send status update information to its neighbor nodes. Neighbor nodes store the received information of each neighbor device, so that users can query and manage the current second-layer connection through the standard SNMP (Simple Network Management Protocol) MIB (Management Inform...
