Referring to figure 2., Fig. 2 is a kind of flow chart of topology discovery method provided by the embodiments of the present application, this method application
In above-mentioned multi-service transport network system 100, described method includes following steps:
Step S110: it obtains at least one branch end access device described in that the center-side MSTP equipment is sent
A certain branch end access device protocol massages.
Wherein, a certain branch end access device is that some branch end access at least one branch end access device is set
Standby, for example, at least one branch end access device includes three branch end access devices, then a certain branch end access device can be with
It is one of branch end access device in three branch end access devices.Center-side access device 110 and each branch end
Operation has a self-defining communication protocol, branch end access device and center-side access device 110 by being somebody's turn to do between access device
Self-defining communication protocol is communicated, and such as each branch end access device can be with active period to the branch end interconnected therewith
MSTP equipment sends the protocol massages of the self-defining communication protocol, carries in the protocol massages of the self-defining communication protocol pre-
If protocol type.Since branch end access device can send the message of various protocols, so, the center-side access device
After 110 receive message from center-side MSTP equipment 120, by judge the type of message of message whether be preset protocol type with
Determine whether the protocol massages from SDH network, when to be, the center-side access device 110 judges the protocol massages
In whether carry logical channel identifier, when to be, execute step S120.
Here, being illustrated by taking branch end access device 140 as an example, wherein by the protocol massages of self-defining communication protocol
Referred to as hello packet, preset protocol type are the type of message of hello packet.140 active period of branch end access device
Hello packet is sent to the branch end MSTP equipment 130 interconnected therewith, carries branch end access device 140 in the hello packet
Relevant device information, the device identification (such as IP address or MAC Address) for example including branch end access device 140, equipment type
Number, device name, device location information etc..Hello packet is transferred to and center-side access device by branch end MSTP equipment 130
The center-side MSTP equipment 120 of 110 interconnections, the identification of center-side MSTP equipment 120 are transmitted from branch end MSTP equipment 130
Hello packet adds logical channel identifier corresponding with 140 physical location of branch end access device for the hello packet
(VLAN ID), and the hello packet is sent to center-side access device 110.
So if the protocol massages (divide for a certain branch end access device at least one branch end access device
Branch end access device 140) send, then the corresponding logical channel of branch end access device 140 is carried in the protocol massages
The device identification of mark and the source branch end access device.
Step S120: logical channel identifier and a certain branch end access device are obtained from the protocol massages
Device identification.
Center-side access device 110 carries after receiving protocol massages from obtaining in protocol massages in the protocol massages
The corresponding logical channel identifier of a certain branch end access device and a certain branch end access device device identification.
For example, the protocol massages are that branch end access device 140 from least one branch end access device is sent,
Then obtain the corresponding logical channel identifier of branch end access device 140 and the device identification of the branch end access device 140.
Step S130: the logical channel identifier is stored with the device identification as corresponding relationship.
Center-side access device 110 is obtaining the corresponding logical channel identifier of a certain branch end access device and device identification
Afterwards, which is stored with device identification as corresponding relationship so that the center-side access device according to
The logical channel identifier and the device identification send datagram to a certain branch end access device.
So center-side access device 110 can directly from center-side MSTP equipment 120, that obtains certain in the present embodiment
The device identification of the corresponding logical channel identifier of one branch end access device and a certain branch end access device, is then deposited
Storage, thus the corresponding relationship of the logical channel identifier and device identification that are stored in center-side access device 110 can and center-side
The corresponding relationship of the logical channel identifier and device identification that store in MSTP equipment 120 saves unanimously, to avoid due to center
End access device 110 and the MSTP apparatus logic channel interconnected with it configuration are inconsistent, cause network change, maintenance and failure row
The problems such as wrong inefficient, difficult.
In addition, center-side access device 110 receive the corresponding logical channel identifier of a certain branch end access device with
The logical channel table of comparisons is produced after device identification, that is, logical channel identifier and the corresponding relationship of device identification are led to logic
The form of the road table of comparisons is stored, and the form of the logical channel table of comparisons is as follows:
The corresponding logical channel identifier of each branch end access device and corresponding is stored in the logical channel table of comparisons
Device identification can also have in center-side MSTP equipment 120 and compare with logical channel consistent in center-side access device 110
Table, so that the logical channel identifier and device identification that are stored in center-side access device 110 and center-side MSTP equipment 120
Between corresponding relationship be consistent.
Since the corresponding relationship between logical channel identifier and device identification may be modified, so, center termination
Enter equipment 110 after obtaining the corresponding relationship of the corresponding logical channel identifier of a certain branch end access device and device identification, also
It can determine whether in the pre-generated logical channel table of comparisons with the presence or absence of pair for having the logical channel identifier Yu the device identification
It should be related to, not there are the corresponding relationship of the logical channel identifier and the device identification in the logical channel table of comparisons,
Then the center-side access device 110 is added to described using the logical channel identifier and the device identification as corresponding relationship
In the logical channel table of comparisons.
In addition, if there are the default corresponding of the logical channel identifier and the device identification in the logical channel table of comparisons
When relationship, in order to guarantee default pair of the logical channel identifier stored in the logical channel table of comparisons and the device identification
Should be related to be correct, thus also need the default corresponding relationship for judging to store in the logical channel table of comparisons whether with institute
It is consistent with the corresponding relationship of the device identification to state logical channel identifier, when to be no, 110 pairs of institutes of the center-side access device
The default corresponding relationship stated in the logical channel table of comparisons is modified, and is set with being changed to the logical channel identifier with described
The corresponding relationship of standby mark is consistent.
It is to be appreciated that corresponding logical channel identifier is if the device identification of a certain branch end access device is 1
100, corresponding relationship 1- > 100, the default corresponding relationship stored in the logical channel table of comparisons may be 1- > 200, then table
The default corresponding relationship stored in the bright logical channel table of comparisons and the corresponding relationship currently obtained are inconsistent, then can be by default correspondence
Relationship is changed to 1- > 100.
So can be updated to pre-generated logical comparison table, according to above two mode so that in logical channel
When being modified, it is ensured that logical channel identifier and equipment in center-side access device 110 and center-side MSTP equipment 120
The corresponding relationship of mark is consistent.
It is patrolled it should be noted that center-side access device 110 can also be that the multiple branch end access devices of acquisition are corresponding
It collects gap marker and device identification generates the corresponding logical channel table of comparisons, access device 110 and branch end at subsequent central end
Access device be updated in the manner described above to the logical channel table of comparisons in communication process.
In addition, if center-side access device 110 can also be patrolled according to updated after the logical channel table of comparisons is updated
It collects the channel table of comparisons and generates logical channel configuration-direct, then configured on the physical interface according to the logical channel configuration-direct
Logical channel corresponding with the logical channel identifier.
Alternatively, in order to automatically complete the logical channel action of configuration of center-side access device 110, the multi-service transport
Network system 100 further includes network controller, and the network controller is connect with the center-side access device 110, center-side
It can be communicated by standard agreement (such as netconf, SNMP) between access device 110 and network controller.
The center-side access device 110 can also send updated logical channel control to the network controller
Then table obtains the logical channel configuration-direct that the network controller is sent according to the logical channel table of comparisons, further according to
The logical channel configuration-direct configures logical channel corresponding with the logical channel identifier on the physical interface.
Wherein, network controller, can be according to strategy built in system or pipe after obtaining the above-mentioned logical channel table of comparisons
The mode of reason person's manual intervention, it is determined whether create and patrol on center-side access device 110 for counterlogic table of comparisons data item
Channel is collected, for example, can choose creation part logical channel can create the whole in logical comparison table by default
Logical channel, thus center-side access device 110 can branch end access device corresponding with the logical channel set up leap
The communication channel of operator's transmission network.
It should be noted that if when center-side access device 110 creates the logical channel table of comparisons in the initial state, then
Corresponding configuration has logical channel corresponding with logical channel identifier, then after the logical channel table of comparisons is updated, center termination
Logical channel can be configured again by entering equipment 110, or only be configured again to the logical channel of mistake.
