Detailed Description

The principles and spirit of the present invention will be described with reference to a number of exemplary embodiments. It is understood that these embodiments are given solely for the purpose of enabling those skilled in the art to better understand and to practice the invention, and are not intended to limit the scope of the invention in any way. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

As will be appreciated by one skilled in the art, embodiments of the present invention may be embodied as a system, apparatus, device, method, or computer program product. Accordingly, the present disclosure may be embodied in the form of: entirely hardware, entirely software (including firmware, resident software, micro-code, etc.), or a combination of hardware and software.

According to the embodiment of the invention, the method and the system for automatically selecting the route based on the two-layer multi-service path are provided, and the method and the system can automatically determine the service path of the access equipment through the two-layer topology according to the known information such as the attributes of the access equipment, the SVLAN and the terminating equipment, thereby greatly reducing the labor cost and providing convenience for operators.

The principles and spirit of the present invention are explained in detail below with reference to several representative embodiments of the invention.

Fig. 1 is a flowchart of an automatic routing method based on two-layer multi-service paths according to an embodiment of the present invention. As shown in fig. 1, the method includes:

step S101, acquiring parameter information of the equipment.

Firstly, parameter information of the device is acquired, and the parameter information comprises: attribute information of the access device, SVLAN (this parameter may be null, if null, SVLAN service path analysis in fig. 2 is not performed), attribute information of the terminating device, maximum hop count (maximum hop count for two-tier topology inquiry), and other known parameter information.

And step S102, inquiring the uplink equipment associated with the access equipment based on the two-layer topological relation according to the parameter information.

The two-layer topological relation is pre-loaded in a two-layer topological relation table (l2topo table), and the two-layer topological relation table stores the topological relation between the devices of each hop.

According to the attribute information of the access device, the bdeviceiid field corresponding to the two-layer topology table can be found in the two-layer topology relationship, and the corresponding ADEVICEID (i.e., the uplink device) is found through the self-association of the two-layer topology relationship, so as to obtain the ID and the port information of the first uplink device.

And step S103, circularly inquiring the uplink equipment corresponding to the uplink equipment until the terminal equipment meeting the preset condition is inquired on the premise that the maximum hop count is not exceeded, or inquiring the maximum hop count.

Taking the ID of the first uplink device as BDEVICEID, inquiring in the two-layer topological relation, and searching for corresponding ADEVICEID to obtain the ID and port information of the corresponding second uplink device; that is, based on the queried uplink device, the uplink device corresponding to the uplink device is queried;

repeating the query steps until the terminal equipment meeting the preset conditions or the maximum hop count is queried;

setting a preset condition according to the attribute information of the terminal equipment, and when the inquired attribute information of a certain uplink equipment conforms to the attribute information of the terminal equipment, indicating that the preset condition is met; in addition, if the inquiry does not exceed the maximum hop count, the uplink equipment is terminal equipment;

for example, the contents of the DEVICEPROPCODE field are set as: and when the queried device attribute information DEVICEPROPCODE is "PRP 004", the PRP004 indicates that the corresponding device is the terminating device, and continues to execute step S104.

The maximum hop count is generally set to 3, and the specific setting can be adjusted according to actual conditions. And if the maximum hop count information is set in the preset condition, the maximum hop count information in the preset condition is used as a standard.

Step S104, when the Nth uplink device meeting the preset conditions is found, stopping the query and using the Nth uplink device as the terminating device, wherein the process can be actually understood as that the terminating device is queried after N hops are passed, and N is less than or equal to the maximum hop count, namely the maximum hop count is not exceeded; and then according to the access equipment, the corresponding uplink equipment and the path information from the access equipment to the terminal equipment, obtaining the path information from the access equipment to the terminal equipment.

Step S105, if the query exceeds the maximum hop count, that is, if the query exceeds the maximum hop count, the uplink device meeting the preset condition cannot be queried, the routing is ended, and the path selection needs to be performed manually.

For the fact that the two-Layer topology of the binding port is not found, but the physical port is found by LLDP (Link Layer Discovery Protocol), and for the reason of the client, the mac cannot find the abnormal situation, the port in the l2topo table query process needs to be processed.

There are two possible causes for this problem: firstly, some binding ports cannot find the two-layer topology, but the physical ports below the binding ports can be found, so the physical ports are reserved, and the physical ports below the binding ports are removed. Secondly, the physical ports under the binding ports cannot use the SVLAN for screening, and the SVLAN comparison screening shown in FIG. 2 can be carried out only by replacing the physical ports with the binding ports.

The specific treatment measures are as follows:

in the l2topo table query process, if a port of portextinfo.

And if the port of the portextinfo.

In an embodiment, if the SVLAN is not empty in the parameter information acquired in step S101, the SVLAN service path analysis may be performed after the path information is obtained in step S104.

Since the path information acquired in step S104 may be multiple pieces, the SVLAN information may be used to filter the pieces of path information, so as to select more accurate path information.

When SVLAN service path analysis is performed, whether an access device is an OLT device must be judged;

if the judgment result is that the network management equipment is OLT equipment, whether the network management equipment has a VLAN (whether the collected VLAN is judged, but not whether the SVLAN is collected) collected by the OLT equipment is continuously judged;

if the SVLAN analysis is acquired, the SVLAN analysis is directly started from the uplink port of the OLT equipment (parameter equipment).

If the data can not be acquired, starting from a lower connection port of an upper connection device (switchboard) of an input parameter device (OLT)

And (6) SVLAN analysis.

If the equipment is not OLT equipment, SVLAN analysis is directly carried out.

The process is mainly to exclude the situation that part of the provincial access OLT equipment does not collect the VLAN.

Fig. 2 may be referred to for specific processes, and fig. 2 is a schematic view illustrating an SVLAN analysis flow according to an embodiment of the present invention. As shown in fig. 2, the method includes:

step S1, according to the obtained path information, determine whether the access device in each piece of path information is an OLT device.

Step S2, if the access device is an OLT device, the access device is queried in a preset VLAN port information table (VLAN table) according to the attribute information and SVLAN information of the access device.

And step S21, if the corresponding record is inquired, selecting the corresponding path information as the final path.

Step S22, if the corresponding record is not inquired, the screening is started from the lower port of the upper connection device of the OLT device, and according to the SVLAN information, the information of the upper connection device and the port information of the upper connection device, the screening is carried out on the upper connection device

Querying in a VLAN port information table; and if the corresponding record is inquired, selecting the corresponding path information as the final path.

Step S3, if the access device is not OLT device, SVLAN analysis is carried out to all the experienced switch port information including the uplink port of the access device, and according to the attribute information of the access device, the uplink port of the access device, SVLAN information, the information of the uplink device and the port information of the uplink device, the query is carried out in VLAN port information table; and if the corresponding record is inquired, selecting the corresponding path information as the final path.

If no corresponding record is found in step S22 or step S3, any of the path information is used as the final path.

In an embodiment, after the filtering of the foregoing step S1, step S2 (step S21, step S22) and step S3, if a path is not found, the data of step S104 is directly used to return flag to 0 (which represents that the automatically selected path is not precisely located); if only one path can be queried, then the return flag is 1 (representing that the automatically selected path is a precise location).

Through the above processes of analysis, automatic routing, etc., path information can be finally obtained, such as:

path: access device-access device upper connection port-switch 1 lower connection port-switch 1 upper connection port-switch 2 lower connection port-switch 2 upper connection port-terminating device.

It should be noted that although the operations of the method of the present invention have been described in the above embodiments and the accompanying drawings in a particular order, this does not require or imply that these operations must be performed in this particular order, or that all of the operations shown must be performed, to achieve the desired results. Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step execution, and/or one step broken down into multiple step executions.

For a clearer explanation of the above automatic routing method based on two-layer multi-service paths, a specific embodiment is described below, but it should be noted that the embodiment is only for better explaining the present invention and is not to be construed as an undue limitation to the present invention.

Taking an access switch with a dedicated line as an example, and combining fig. 1 and fig. 2, the path information of the access device is obtained by using an automatic routing method based on a two-layer multi-service path, and the process is as follows:

firstly, in conjunction with step S101, an access switch with a dedicated line is found, and the information of the access device is as follows:

DEV0057w wideland S930010.9.8.226

interface XGigabitEthernet3/0/0

description TO_anjiamenjingzhunfupin

port link-type access

port default vlan 2865

traffic-policy wangzhan inbound

It can be seen that the name of the access device: broad plateau S9300; IP address: 10.9.8.226, respectively; port information: XGigabitEthernet 3/0/0; SVLAN: 2865.

attribute information of terminating device (DEVICEPROPCODE): PRP 004.

The maximum number of hops is set to 3.

And step S102, searching for the uplink equipment, searching for a corresponding BDEVICEID field in the two-layer topological relation according to the attribute information of the access equipment, and searching for corresponding ADEVICEID through self association of the two-layer topological relation to obtain that the uplink equipment is a '9312 switch'. The execution procedure is as follows:

select AD.DEVICENAME,AD.LOOPADDRESS,A.*

from l2topo a,device ad,device bd

where bd.loopaddress＝'10.9.8.226'

and a.adeviceid＝ad.deviceid

and a.bdeviceid＝bd.deviceid

fig. 3 is a schematic diagram of a query result of an uplink device according to an embodiment. As can be seen from fig. 3, the device name (DEVICENAME) of the uplink device is shanyang S9312;

the IP for the cyclic address (LOOPADDRESS) is 10.9.8.250;

connection ID (LINKID) is SX-SL 669;

ADEVICEID field is DEV005a9, namely ID corresponding to the uplink device "Shanyang S9312";

the lower port (DOWNPORT) is XGigabitEthernet 11/0/3;

the bdeviceiid field is DEV0057w, which is the ID of the access device in step S101;

the upper port (UPPORT) is XGigabitEthernet 3/0/0.

And step S103, circularly searching the uplink equipment of the uplink equipment according to the attribute information of the uplink equipment.

Because the attribute information (DEVICEPROPCODE) PRP004 of the terminating device, the preset condition is that "PRP 004" is queried for DEVICEPROPCODE.

If the uplink device "shanyang S9312" found in step S102 does not match, the uplink device continues to find, and the uplink device that can obtain the "9312 switch" has 3 devices, and the 3 devices are the terminating devices. The execution procedure is as follows:

select AD.DEVICENAME,AD.LOOPADDRESS,ad.devicepropcode,A.*

from l2topo a,device ad,device bd

where bd.loopaddress＝'10.9.8.250'

and a.adeviceid＝ad.deviceid

and a.bdeviceid＝bd.deviceid

fig. 4 is a schematic diagram of a query result of the terminating device according to a specific embodiment.

As can be seen from fig. 4, 4 query results are obtained through the query, and DEVICEPROPCODE of the 4 results is "PRP 004", and the query hop count is 2, and does not exceed the maximum hop count of 3, which indicates that the corresponding device is the terminating device.

The terminating device names (DEVICENAME) are:

SL-SY-MSE-1.MAN.M6000、

SL-SY-MSE-2.MAN.M6000、

SL-LDL-BAS-3.MAN.ME60；

the IPs are 219.145.240.233, 219.145.240.232, 219.145.240.245, respectively.

Thus, 3 pieces of path information can be acquired:

"broad terrace S9300" - "9312 switch" - "SL-SY-MSE-1. man.m 6000"

"broad terrace S9300" - "9312 switch" - "SL-SY-MSE-2. man.m 6000"

"broad band S9300" - "9312 switch" - "SL-LDL-BAS-3. man. me60"

Further, in combination with the SVLAN analysis process of fig. 2, the SVLAN service path analysis (mainly, port information of the screening device) is performed according to the three pieces of path information obtained in the previous step, and the port of the aggregation switch can be found in the VLAN transparently transmitted through the interface of the aggregation switch through the VLAN.

The execution procedure is as follows:

select*from VLANPORT WHERE DEVICEID＝'DEV005a9'AND VLANID＝'2865'

as shown in figures 5, 6 and 7,

figure 5 is a port description schematic of the 9312 switch embodiment,

figure 6 is a diagram of one embodiment of ADEVICEID field and dowport field tag for the 9312 switch,

fig. 7 is a schematic diagram of the BDEVICEID and UPPORT field labels of SL-LDL-BAS-3.man. me60, according to an embodiment.

As can be seen from fig. 5 to 7, the device ID (deviceid) of the "9312 switch" is DEV005a9, the VLAN ID is 2865, and the type Conversion (CHANGETYPE) is 0; the port information (PORTDESCR) in FIG. 5 includes Eth-Trunk1, Eth-Trunk2, Eth-Trunk6, XGdiabtite Ethernet 11/0/3.

In fig. 6 and 7, as can be seen from the

label boxes

601 and 701, the ports Eth-Trunk1 and xgigabit ethernet11/0/3 of the "9312 switch" exist in the path information, and therefore the final path is:

"widelane S9300" - "9312 switch" - "SL-LDL-BAS-3. man. me60".
