Embodiment
Below by drawings and Examples, the technical scheme of the embodiment of the present invention is described in further detail.
For convenience of understanding, the network of take in Fig. 1 is the example explanation.
Fig. 1 is the networking schematic diagram of a data center Campus Networks, comprises detecting devices 101, core layer switch 102, convergence- level switch 103 and 104, access- layer switch 105 and 106, physical server 107 and 108, VM109.Wherein detecting devices 101 refers to the equipment of initiating extended MAC ping message, can be for example that the three-layer network of outside access Campus Networks closes equipment, can be also core layer switch or the convergence-level switch in data center.VM109 is arranged on physical server 107.Access-layer switch 105 is direct-connected with physical server 107, is the access device of VM109.
Now need to be from the positional information of detecting devices 101 location VM109.
Above-mentioned core layer switch 101, convergence- level switch 102 and 103, access- layer switch 105 and 106, on the equipment form, can be switch, can be also router.
Embodiment mono-
In embodiment mono-, for instance, suppose the core layer switch 102 in Fig. 1, convergence- level switch 103 and 104 and access-layer switch 105 learnt the MAC Address of VM109.
As shown in Figure 2, the embodiment of the present invention provides a kind of method of locating virtual machine VM position, is applied to the access device of the described VM in described data center, comprising:
201, receive the extended MAC ping message that detecting devices mails to described VM, destination address in described extended MAC ping message is the MAC Address of described VM, described extended MAC ping message carries the first sign, and described the first sign means that described extended MAC ping message is the MAC ping message of the positional information for inquiring about VM.
Access-layer switch 105 receives the extended MAC ping message that detecting devices 101 mails to VM109, destination address in described extended MAC ping message is the MAC Address of VM109, described extended MAC ping message carries the first sign in MAC ping heading, this first sign is for to notify this message of receiving device be not common MAC ping message, but for the MAC ping message of the positional information of inquiring about VM.
For instance, reference table 1, table 1 is the structure of common MAC ping message, can ethernet operation in table 1, administer and maintain in heading (Ethernet OAM Header) and increase described the first sign.
Table 1
Before access-layer switch 105 receives the extended MAC ping message that detecting devices 101 mails to VM109, detecting devices 101 sends extended MAC ping message to survey the positional information of VM109 to VM109.
After convergence-level switch 103 is received extended MAC ping message, if in the situation that TRILL will directly be transmitted to access-layer switch 105; If, in the situation that common double layer network agreement is searched transmitting of self, find the MAC Address of VM109, down hop access-layer switch 105 forwards.
Therefore, access-layer switch 105 receives the extended MAC ping message that detecting devices 101 mails to VM109.
202, determine in described extended MAC ping message the MAC Address that carries described the first sign, self directly with described VM, is connected and self preserved described VM, send a reply message to detecting devices, described reply message is the response to described extended MAC ping message, the positional information of in described reply message, carrying described VM.
The MAC Address that VM109 is arranged in the transmitting of access-layer switch 105 self.But it is direct-connected (interval one jump) or indirectly can reach (interval multi-hop) that access-layer switch 105 also needs to judge self and VM109, because, only in the situation that direct-connected, just can make positioning position information accurate.For instance, the role of pre-configured access-layer switch 105 is access device artificially, directly connects the equipment of VM.
Access-layer switch 105 carries described the first sign in having determined described extended MAC ping message, self directly is connected with VM109 and self preserved the MAC Address of VM109 after, access-layer switch 105 sends a reply message to detecting devices 101, the positional information of in described reply message, carrying VM109.
For instance, the positional information of VM109, can comprise the MAC Address of access-layer switch 105 and the port numbers of the physical port that is connected physical server 107.
Again for instance, the positional information of VM109, except the port numbers of the MAC Address that comprises access-layer switch 105 and the physical port that is connected physical server 107, the device name that can also comprise access-layer switch 105, or the title of the physical port of connection physical server 107, or the port numbers of the virtual port of connection VM109.
The positional information of VM109, can be carried in the payload payload in table 1.
In prior art, in the situation that TRILL, the MAC ping that detecting devices is initiated can only detect detecting devices to bridge device (the Route Bridge according to routing mode work, RB) connectedness between, the destination address of MAC ping is core layer switch or convergence-level switch or access-layer switch in Fig. 1,102～106; In the situation that common double layer network, the destination address of the MAC ping that detecting devices is initiated can be VM, but, because VM can not identify MAC ping message, can abandon this message, and detecting devices also can't learn which access device VM is connected on.
The method of the virtual machine VM position, location that the embodiment of the present invention provides, after access device by the described VM in data center receives the extended MAC ping message that detecting devices sends, after determining and self directly with described VM, being connected and self having preserved the MAC Address of described VM, send a reply message to detecting devices, the positional information of in replying message, carrying described VM, comprise the MAC Address of self and the port numbers of the physical port that is connected physical server etc., solved in the prior art and in TRILL network and common double layer network, used MAC ping can't locate the problem of VM position.
Embodiment bis-
Embodiment bis-provides the method for virtual machine VM position, another kind of location, for instance, supposes the core layer switch 102 in Fig. 1, and convergence- level switch 103 and 104 does not also have the MAC Address of study to VM109.But because access-layer switch 105 is access devices of VM109, so access-layer switch 105 has been learnt the MAC Address of VM, and access-layer switch 106 is not the access device of VM109, so access-layer switch 106 does not have the MAC Address of study to VM109.
Detecting devices 101 sends extended MAC ping message to survey the positional information of VM109 to VM109, destination address in described extended MAC ping message is the MAC Address of VM109, described extended MAC ping message carries the first sign in MAC ping heading, this first sign is for to notify this message of receiving device be not common MAC ping message, but for the MAC ping message of the positional information of inquiring about VM.
In the present embodiment, access- layer switch 105 and 106 receives respectively the extended MAC ping message that detecting devices mails to VM109.
The role who supposes artificial pre-configured access- layer switch 105 and 106 is access device.
Access-layer switch 105 is found the MAC Address that VM109 is arranged in transmitting of oneself, determined in described extended MAC ping message that carrying described first identifies, self directly is connected with VM109, therefore, access-layer switch 105 sends a reply message to detecting devices 101, the positional information of in described reply message, carrying VM109.
Access-layer switch 106 has determined in described extended MAC ping message that carrying described first identifies, but access-layer switch 106 is not found the MAC Address that VM109 is arranged in transmitting of oneself, self directly is not connected with VM109, so access-layer switch 106 is by extended MAC ping packet loss.
In the present embodiment, with the similar part of embodiment mono-, repeat no more.
