Abstract
The invention discloses a method and system for automatically determining uploading information of an EOC head end. The method includes the steps that after an automatic finding switch at the EOC head end is turned on, the EOC head end sends an inquiring frame to an Ethernet network which the EOC head end belongs to in a timing mode; after receiving the inquiring request frame of the EOC head end, an optical network unit (ONU) records information of the EOC head end and sends a response frame; after receiving the response frame, the EOC head end records information of the ONU position and generates the uploading information of the EOC head end for inquiring by a network management system. By means of the method and system, the uploading information of the EOC head end and change conditions of the uploading information of the EOC head end can be perceived in time, and an operation and maintenance worker can conveniently manage devices.
Description
Technical field
The present invention relates to CHINA RFTCOM Co Ltd EPON+EOC association system, particularly relate to a kind of method and system automatically determining EOC head end first line of a couplet information.
Background technology
Traditional CHINA RFTCOM Co Ltd, after bidirectional network reconstruction, generally all adopts the joint network structure of EPON+EOC.Wherein EPON (Ethernet Passive Optical Network) is ethernet passive optical network, and EOC (Ethernet over Coax) passes through co-axial cables transport for ether data.In this network configuration, EPON and EOC as two independently system add in network management system.But EOC head end upper united mouth and ONU (Optical Network Unit) optical network unit in actual networking) Ethernet interface is connected.Like this when EOC head end quantity is large and first line of a couplet port changes, attendant cannot the change of Timeliness coverage EOC head end first line of a couplet TOPO information.
Summary of the invention
The technical problem to be solved in the present invention is for above-mentioned defect of the prior art, there is provided a kind of can the method for the EOC of perception in time head end first line of a couplet information change situation, operation maintenance personnel can see the connection state of EOC head end and upper network device very intuitively, facilitates operation maintenance personnel to the management of equipment.

Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Automatically the system determining EOC head end first line of a couplet information based on broadcasting and TV EPON+EOC network configuration of the embodiment of the present invention, can realize the timely first line of a couplet information of perception EOC head end and the change information of first line of a couplet port in CHINA RFTCOM Co Ltd EPON+EOC association system.Operation maintenance personnel can see the TOPO structure of EOC head end and upper network device very intuitively.Facilitate client or operation maintenance personnel to the quick position of fault and other network managements.
This system comprises EOC head end inquiry frame generation module, ONU response frame generation module and EOC head end logging modle, wherein, EOC head end inquiry frame generation module, after the automatic discovery switch on EOC head end is opened, timing sends inquiry frame to affiliated Ethernet; ONU response frame generation module, for receive EOC head end in optical network unit ONU inquiry request frame after, record EOC head end information, and send response frame; EOC head end logging modle, for recording ONU positional information after EOC head end receives response frame, generating EOC head end first line of a couplet information, inquiring about for webmaster SERVER.
As shown in Figure 1, be EPON system, structural representation between EOC system and network management system.EPON system comprises OLT and holds (i.e. optical line terminal optical line terminal) and ONU end, and wherein OLT end is used for carrying out OAM message with ONU end alternately, distributes ONU index by OAM message when ONU reaches the standard grade; ONU end initiates inquiry frame for responding EOC head end, obtains the EOC head end IP in message, and records the mapping relations of Ethernet interface and EOC head end.
As shown in Figure 2, for automatically determining the specific embodiment of the system of EOC head end first line of a couplet information based on broadcasting and TV EPON+EOC network configuration.Wherein webmaster SERVER holds, for being managed the network equipment by SNMP message.The automatic discovery switch of EOC head end can be opened by webmaster SERVER end, allow EOC head end initiate the first line of a couplet and find query message.Simultaneously webmaster SERVER end is mutual by SNMP message and EOC head end, inquires about the first line of a couplet positional information of EOC head end.
EOC head end for initiating query message, and can obtain first line of a couplet ONU positional information from response message, these positional informations is returned to SERVER end when webmaster SERVER end is inquired about by SNMP message.
Fig. 3 is message flow chart of the present invention, and this flow process is based on the system of foregoing embodiments, and detailed process is as follows:
Step S101: webmaster SERVER end is mutual by SNMP message and EOC head end, opens the first line of a couplet discovery switch of EOC head end.
Step S102:EOC head end timed sending inquiry frame, as can be setup times be 30s.This inquiry frame is broadcast frame, and frame type is (0x8891).Should with EOC head end IP address information in this inquiry frame, as the specific message between ONU and EOC headend, for exchange message.Message format is see Fig. 4, and each meaning of parameters is as follows:
A) MAC is broadcasted: Ethernet target MAC (Media Access Control) address is broadcast address ff:ff:ff:ff:ff:ff.
B) CLT MAC:EOC head end MAC Address.
C) frame type: 0x8891.
D) type of message: 0x01.
E) the IP address of CLT IP:EOC head end.
F) reserve bytes: reserve bytes is full 0, as expanding use later.
After step S103:ONU receives the inquiry frame that EOC head end sends over, take out MAC Address and the IP address of EOC head end, set up the mapping relations between ONU UNI mouth and EOC head end information, and reply ONU response frame.Frame format is see Fig. 5, and each meaning of parameters is as follows:
A) MAC Address of CLT MAC:EOC head end.
B) MAC Address of ONU MAC:ONU.
C) frame type: 0x8891.
D) type of message: 0x02.
E) the device type coding of ONU type: ONU.
F) the ethernet side slogan of ONU UNI mouth: ONU.
G) reserve bytes: reserve bytes is full 0, as expanding use later.
After step S104:EOC head end receives ONU response frame, from message, parse ONU positional information.Comprise ONU MAC Address and ONU end slogan.In order to the first line of a couplet positional information of real-time update EOC head end, EOC head end often can send one query frame by 30s, and waits for the response message of ONU end, if the continuous response frame not receiving ONU end for 3 times, then think that its first line of a couplet ONU does not exist, EOC end needs to remove first line of a couplet ONU positional information record.
Step S105: network management system inquiry EOC head-end location information.
In order to the mapping relations of real-time update ONU UNI mouth and EOC head end, ONU end needs to wait for the inquiry frame of EOC head end next time after sending response frame, if the continuous inquiry frame not receiving EOC head end for 3 times, then think that its second line of a couplet EOC head end does not exist, ONU needs the mapping relations removing UNI mouth and second line of a couplet EOC head end.By said method, the present invention automatically can find the network configuration of EOC head end first line of a couplet equipment in CHINA RFTCOM Co Ltd EPON+EOC association system, the change of first line of a couplet device port information detected in time.Operation maintenance personnel can see the TOPO structure of EOC head end and upper network device very intuitively, facilitates client or operation maintenance personnel to the quick position of fault and other network managements.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection range that all should belong to claims of the present invention.
