Abstract
The method for finding a light module includes the steps that a light module finding device acquires IP address information of a first interface, IP address information of a second interface which is arranged in a loop and located between the first interface and a first host device, and IP address information of a third interface in the loop, and sends a light module detection message to the second interface; when a response message of the light module to be found is received within preset time, the light module to be found is found. It can be seen that due to the IP address information of the second interface as a relay point and the IP address information of the third interface as a destination point are carried by the light module detection message sent by the light module finding device, the light module detection message cannot be uploaded even though the message is firstly forwarded to the host device where the light module to be found is located due to the fact that an interface of the light module to be found is not connected, and therefore the success rate of finding the light module is increased.

For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with accompanying drawing, the embodiment of the present invention is described in detail.
Embodiment mono-
A kind of method flow diagram of finding optical module that Fig. 2 provides for the embodiment of the present invention, described method is applied in network, described network comprises optical module discovering device and a plurality of host equipment, each host equipment has a plurality of interfaces, described a plurality of host equipment is connected to form loop by interface, described a plurality of host equipment accesses the interface of described loop also for connecting optical module, described optical module discovering device is connected with the first host equipment, when when finding that the first interface of optical module with the second host equipment is connected, described the first host equipment is in described a plurality of host equipment, described the second host equipment is in described a plurality of host equipment, as shown in Figure 2, comprise:
S201: described optical module discovering device obtain the IP address information of described first interface and in described loop the IP address information of the second interface between described first interface and described the first host equipment, described the second interface is to have connected the interface of finding optical module.
S202: described optical module discovering device obtains the IP address information of the 3rd interface in described loop, described the 3rd interface is not that the first host equipment described in described loop arrives the interface between described first interface by described the second interface, and described the 3rd interface is less than described the 3rd interface by described first interface to described loop interface quantity partly between described the second interface and by described the first host equipment, arrives the interface quantity of described loop part between described the second interface.
For optical module discovering device described in S201 and S202, obtaining interface IP address information it should be noted that, described optical module discovering device can obtain by different modes the IP address information of each interface on described loop, can obtain by pre-configured, also can be by existing network instrument for example, tracert instrument after surveying described loop, obtain, the present invention does not limit this.
Position for described the second interface is selected, and it should be noted that, due in a loop, from this loop, in general a node is to have two paths optional to another node, a clockwise path, a counterclockwise path.For described the second interface, both can be on the clockwise path from described the first host equipment to described first interface, also can be on the counterclockwise path from described the first host equipment to described first interface, the present invention does not limit this, as long as described the second interface has connected found optical module.The effect of described the second interface is, because described the second interface has connected an optical module of having found, described optical module discovering device can be using described the second interface as the described relay point that sends described optical module probe messages, the 3rd interface that coordinates S102 to determine determine described optical module probe messages the path of process must pass through described in the described first interface that connects of optical module to be found.
Position for described the 3rd interface is selected, it should be noted that, the position of described the second interface that S201 determines can have influence on the position that S202 determines described the 3rd interface, because the described optical module probe messages that hope is sent from described the first host equipment must be passed through described first interface, therefore when described the second interface is positioned at the clockwise path from described the first host equipment to described first interface, described the 3rd interface is positioned at the clockwise path from described first interface to described the second interface, when described the second interface is positioned at the counterclockwise path from described the first host equipment to described first interface, described the 3rd interface is positioned at the counterclockwise path from described first interface to described the second interface.Simultaneously, sending direction in order to ensure described optical module probe messages can not change, this step is when determining described the 3rd interface, to also having requirement the interface number the interface number the clockwise path from described the second interface to described the 3rd interface and the counterclockwise path from described the second interface to described the 3rd interface, this part is described the related content in conjunction with described the second interface after having introduced S203 and S204.
S203: described optical module discovering device sends optical module probe messages to described the second interface, the object IP address of described optical module probe messages is the IP address information of described the second interface, and carry described the 3rd interface IP address information and described in the Electronic Serial Number sign ESN ID of optical module to be found.
It should be noted that, at the location positioning by described the first host equipment and described first interface, go out after described the second interface and described the 3rd interface, the described optical module discovering device being connected with described the first host equipment will pass through the interface of described the first host equipment, utilize the physical topological structure of described loop, to described the second interface, send described optical module probe messages, described optical module probe messages is when arriving described the second interface, do not need the intervention of the host equipment of described the second interface, what be connected with described the second interface has describedly found that optical module can complete voluntarily to the modification of described optical module probe messages object IP address and the operation that forwards to described the 3rd interface, increased the scope of application of the embodiment of the present invention.
S204: described optical module discovering device do not receive in the given time described in when finding the response message of optical module, re-execute S202, when described in described optical module discovering device is received in the given time when finding the response message of optical module, optical module to be found described in discovery.
It should be noted that, described wait finding that optical module receives after described optical module probe messages, can return to response message, so that described optical module discovering device with described in optical module to be found connect, complete the operation of finding optical module, but in the situation that may occur, such as when described in described the 3rd interface of determining is exactly when finding the described first interface that optical module connects, or may occur that described optical module probe messages cannot send to the situation of described first interface, therefore for this situation, described optical module discovering device has been set a scheduled time, described in this scheduled time is enough, optical module to be found returns to response message, such as 1 second kind, when sending described optical module probe messages and not receiving the response message returning after 1 second, described optical module discovering device will re-execute S202, in meeting S202, in the interface of the 3rd interface condition, redefine an interface as the 3rd interface, and send again described optical module probe messages, what in the current described optical module probe messages sending, carry is exactly the IP address information of described the 3rd interface that redefines out.Until the response message that described in obtaining in the given time, optical module to be found returns, when but only may appear at described the 3rd interface and be exactly described first interface due to the above-mentioned situation of not receiving in the given time response message, therefore optical module probe messages can complete the operation of optical module to be found described in discovery described in twice of general maximum transmission.
Can find out, in by optical module described to be found and the formed loop of described optical module discovering device place host equipment, in the described optical module probe messages that described optical module discovering device sends, carry using described the second interface as relay point with as the IP address information of described the 3rd interface of point of destination, the IP address information of the object IP address that is to say described optical module probe messages arbitrary interface of the host equipment of optical module to be found institute connecting interface described in can not being, even if make described optical module probe messages can not uploaded described in being first forwarded to described in the host equipment of finding optical module place has to connect when finding the interface of optical module yet, thus, optical module to be found can receive described optical module probe messages certainly, improved the success rate of finding optical module.
The topological schematic diagram of a kind of optical module network that Fig. 3 provides for the embodiment of the present invention, for more intuitively clear, next in connection with S203 and S204 feature partly, and by Fig. 3, the deterministic process of the second interface described in S201 and S202 and described the 3rd interface is described, as shown in Figure 3, comprise R1 to R4 totally four host equipments, each host equipment has two interfaces and is connected in loop, is respectively a1 to a8 totally eight interfaces.R1 is connected with optical module discovering device, and optical module A to be found is connected to the interface a6 upper (namely first interface) of R3.In Fig. 3, by having connected one on the interface a4 of R2, found optical module B, described optical module discovering device is using the described a4 that has found optical module B connection as the second interface.When determining the 3rd interface, selectable interface range first can not be between first interface and the second interface interface, namely the a5 in Fig. 3 can not be confirmed as described the 3rd interface, if determine that a5 is the 3rd interface, after so described optical module probe messages forwards by a5 (the second interface), the a6 that described in must passing through, optical module to be found connects.The optional scope of described the 3rd interface is an interface in a1, a2, a3, a6, a7 and a8, but, it should be noted that when in network, message sends, when sending node when having two paths between destination node, generally can automatically select through that few paths of number of nodes.If while selecting the 3rd interface to be a2, when described optical module probe messages arrives a4, revising object IP address is the IP address information as the a2 of the 3rd interface, the described optical module probe messages sending to a2 may directly be sent to a2 from a4, the a6 that described in also must passing through, optical module to be found connects clockwise.Therefore in situation shown in Fig. 3, when a4 is positioned on the counterclockwise path from R1 to a6, guaranteed that described optical module probe messages sends from R1 to a6 along counterclockwise path, described the 3rd interface counterclockwise to a4 the interface quantity of process must be less than described the 3rd interface arrive clockwise a4 the interface quantity of process, namely the optional scope of described the 3rd interface is further defined in a6, a7 and a8.
Next by the basis of embodiment as shown in Figure 2, from described this side of optical module of having found being connected with described the second interface, to described, found how optical module is processed the described optical module probe messages receiving and forwarded and be described.
Optionally, Fig. 4, for the embodiment of the present invention provides a kind of method flow diagram that forwards optical module probe messages, as shown in Figure 4, comprising:
S401: describedly found that optical module obtains described optical module probe messages, the object IP address of revising described optical module probe messages is the IP address information of described the 3rd interface, amended optical module probe messages carry described in the ESN ID of optical module to be found.
S402: describedly found that optical module sends described amended optical module probe messages to described the 3rd interface.
That is to say, according to the type of described optical module probe messages, as the described of relay point, found that optical module is when receiving described optical module probe messages, do not need the host equipment under described the second interface to get involved, can certainly be about to the IP address information of described the 3rd interface that described optical module probe messages carried to be originally revised as described optical module probe messages object IP address.Described optical module probe messages sends over by carrying out S203.
Next on the basis of embodiment as shown in Figure 4, from this side of optical module described to be found, how optical module described to be found is processed to the described amended optical module probe messages receiving and be described.
Optionally, a kind of method flow diagram that receives optical module probe messages that Fig. 5 provides for the embodiment of the present invention, as shown in Figure 5, when described amended optical module probe messages arrives described first interface, comprising:
S501: be connected to described first interface described in optical module to be found detect described amended optical module probe messages entrained described in the ESN ID of optical module to be found.
Amended optical module probe messages described here sends over by carrying out S402.
S502: described in after finding optical module comparison, confirm to detect described in the ESN ID of optical module to be found identical with the ESN ID of self.
S503: described in amended optical module probe messages described in optical module selective reception to be found.
That is to say, even if described amended optical module probe messages may not be (at the 3rd interface different with described first interface in the situation that) that is sent to described first interface, optical module described to be found still can detect through the described amended optical module probe messages of described first interface whether carry ESN ID, and whether compare described ESN ID identical with the ESN ID of self.As long as identical, described in optical module to be found just can selective reception described in amended optical module probe messages, even if the object IP address of described amended optical module probe messages may not be the IP address information of described first interface.
S504: described in optical module to be found to described optical module discovering device, return to described response message.
The described response message sending by this step, in S204, described optical module discovering device will receive described response message in the given time, set up with described in being connected of optical module to be found, complete the operation of optical module to be found described in discovery.
Next, in connection with the content shown in Fig. 2, Fig. 4 and Fig. 5, take Fig. 3 as basis, technical scheme of the present invention is illustrated on the whole.
Suppose that described optical module discovering device determines that from the E of region a6 is as described the 3rd interface (namely the 3rd interface situation identical with first interface), when described optical module discovering device sends described optical module probe messages (the IP address information that object IP address is a4 from R1 to a4, carry a6 IP address information and described in wait the ESN ID that finds optical module A) time, the transmission path of described optical module probe messages is from a2 → a3 → a4, what be connected with a4 has describedly found that optical module B receives after described optical module probe messages, the IP address information of a6 is modified in the object IP address of described optical module probe messages, by amended described optical module probe messages (the IP address information that object IP address is a6, the ESN ID of optical module A to be found described in carrying) to a6, forward, the transmission path of described optical module probe messages is from a4 → a5 → a6, but when described optical module probe messages arrives a5, due to the current object IP address of the described optical module probe messages IP address information that is a6, and a5 and a6 belong to same host equipment R3, cause described optical module probe messages by R3, to be uploaded by a5, cannot send to a6 (it should be noted that, be not just necessarily to cause message cannot send to a6 in described the 3rd interface situation identical with first interface, if also connected on a7 or a8, found optical module, and described optical module discovering device is using a7 or a8 as the second interface, so described optical module probe messages can successfully be sent to a6, make described optical module discovering device complete the operation of optical module A to be found described in discovery).
When described optical module discovering device is not received response message in the given time, again from the E of region, determine that a7 is as described the 3rd interface (the 3rd interface situation different with first interface), described optical module discovering device sends described optical module probe messages (the IP address information that object IP address is a4 from R1 to a4, carry a7 IP address information and described in the ESN ID of optical module A to be found), the transmission path of described optical module probe messages is from a2 → a3 → a4, what be connected with a4 has describedly found that optical module B receives after described optical module probe messages, the IP address information of a7 is modified in the object IP address of described optical module probe messages, by amended described optical module probe messages (the IP address information that object IP address is a7, the ESN ID of optical module A to be found described in carrying) to a7, forward, the transmission path of described optical module probe messages is from a4 → a5 → a6 → a7, when described optical module probe messages arrives a5, due to the object IP address of the described optical module probe messages IP address information that is a7, it is not the IP address information (the namely IP address information of a5 or a6) of any one interface of host equipment R3 under a5, therefore a5 can not upload described optical module probe messages, but can continue described optical module probe messages to send to a7, when described optical module probe messages forwards arrival a6, described in connecting with a6, optical module A to be found detects described optical module probe messages and finds that entrained described ESN ID is identical with the ESN ID of self, optical module probe messages described in optical module A to be found selective reception, and to described optical module discovering device, return to response message according to described optical module probe messages, so that described optical module discovering device completes the operation of optical module A to be found described in discovery.
