Realization method and system for enabling LLDP function on non-Ethernet link

Abstract

The invention discloses a realization method for enabling a function of a link layer discovery protocol (LLDP) on a non-Ethernet link. The realization method comprises the following steps that: global enable of an LLDP is respectively started on network equipment of a home terminal and network equipment of an opposite terminal; port enable of an LLDP is respectively started on a non-Ether interface of network equipment of the home terminal and a non-Ether interface of network equipment of the opposite terminal; when an HelloTime is reached, an LLDP Hello message is assembled on a port of the home terminal, and the message is sent to the opposite terminal; and the LLDP Hello message is received and is processed according to an LLDP protocol so as to generate and update neighboring information. According to the invention, an objective of utilizing an LLDP neighboring discovery function on a non-Ethernet link is achieved; besides, the implementation is simple and the cost is low. In addition, the invention also discloses a realization system for enabling the LLDP function on the non-Ethernet link. The system comprises a global enable open module, a port enable open module, an interface binding module, a message sending module, a message receiving module and an aging module.

Description

technical field [0001] The present invention relates to the field of data communication technology, in particular to a POS (Packet Over SONET / SDH, grouping on SONET / SDH) port, HDLC (High-Level Data Link Control, advanced data link control), FR (Frame Relay , Frame Relay), ATM (Asynchronous Transfer Mode, Asynchronous Transfer Mode) ports and other non-Ethernet wide area networks enable LLDP (Link Layer Discovery Protocol, Link Layer Discovery Protocol) function of the implementation method and system. Background technique [0002] 1. Introduction to LLDP: [0003] With the widespread application of Ethernet technology in LANs and MANs, the types of network devices are increasingly diverse and their configurations are intricate, and users have higher and higher requirements for Ethernet management capabilities. At present, many network management systems use the automatic discovery function to track topology changes, but most of them can only analyze the topology structure o...

Problems solved by technology

[0017] The LLDP protocol only stipulates the specific implementation of enabling LLDP functions in Ethernet networks. The existing protocol standards do not involve the enabling of LLDP functions on non-Ethernet link WANs such as POS ports, and there is no specification definition for supporting LLDP neighbor discovery functions on POS interfaces.
