Embodiment
Describe embodiment of the present invention in detail below in conjunction with accompanying drawing.
Referring to Fig. 1, the recognition methods that this illustrates a kind of physical node in embodiment of the present invention cloud operating system comprises step:
Step S101: adopt Simple Network Management Protocol (SNMP) to send request the protocol Data Unit (PDU) of host computer system time (hrSystemDate) to the physical node in cloud operating system;
When sending PDU, can, according to IP address, described physical node place, to described physical node, send PDU.
Step S102: receive corresponding the replying of PDU of the described request host computer system time that described physical node returns, and judge that according to this type of described physical node is server or the network equipment.
For the PDU of requesting host system time, server has the ability to return the host computer system temporal information, and the network equipment can't return time information.Therefore, if corresponding the replying as temporal information of the PDU of the described request host computer system time received, the type of judging described physical node is server; If what the PDU of the described request host computer system time received was corresponding replys as NULL, the type of judging described physical node is the network equipment.
The embodiment of the present invention is utilized the dissimilar physical node characteristics different to the responding ability of some particular request dexterously, and surveyed by sending request, and monitor whether to receive and reply, thus the type of differentiation physical node.Thereby realized the automatic management to physical node, and very quick.
Preferably, can also further from the network equipment, distinguish switch, that is, can also comprise step S103 and S104, as shown in Figure 2:
Step S103: after the type of judging described physical node is as the network equipment, send request the PDU of basic bridge address (dot1dBaseBridgeAddress) to described physical node;
Step S104: receive corresponding the replying of PDU of the basic bridge of the described request address that described physical node returns, and judge according to this whether the type of described physical node is switch.
For asking the PDU of basic bridge address, the switch in the network equipment has the ability to return mac address information, and non-switch can't return to mac address information.Therefore, if corresponding the replying as mac address information of the PDU of the basic bridge of the described request received address, the type of judging described physical node is switch; If what the PDU of the basic bridge of the described request received address was corresponding replys as NULL, the type of judging described physical node is not switch.
Preferably, can also further from the network equipment of non-switch, distinguish router, that is, can also comprise step S105 and S106, as shown in Figure 3:
Step S105: when judging described physical node as the network equipment and being not switch, send request the PDU of IP packet Forwards Forwarding (ipForwarding) to described physical node;
Step S106: receive corresponding the replying of PDU of the described request IP packet Forwards Forwarding that described physical node returns, judge according to this whether the type of described physical node is router.
For the PDU of request IP packet Forwards Forwarding, the router in the network equipment has the ability to return IP packet Forwards Forwarding information, and non-router can't return to IP packet Forwards Forwarding information.Therefore, if the PDU of the described request IP packet Forwards Forwarding received corresponding reply value for meaning to have the Forwards Forwarding function (for example 1), the type of judging described physical node is router; Reply value for meaning not have the Forwards Forwarding function (for example 2) if the PDU of the described request IP packet Forwards Forwarding received is corresponding, the type of judging described physical node is not router.
Wherein, above-mentioned steps S103 and S104, immutable with the order of step S105 and S106.; need to first utilize the PDU judgement physical nodes of request dot1dBaseBridgeAddress is the switch in the network equipment; if not; the PDU judgement physical nodes of recycling request ipForwarding is the router in the network equipment, and the design of this judgement order is in order to guarantee that the PDU for surveying can effectively distinguish dissimilar physical node.
In order to realize said method, the embodiment of the present invention also provides the recognition device of a kind of physical node in cloud operating system, as shown in Figure 4, comprising:
The first sending module, adopt Simple Network Management Protocol (SNMP) to send request the protocol Data Unit (PDU) of host computer system time to the physical node in cloud operating system;
First receives detection module, receives corresponding the replying of PDU of the described request host computer system time that described physical node returns, and judges that according to this type of described physical node is server or the network equipment.
Wherein, described the first sending module, can, according to IP address, described physical node place, send request the PDU of host computer system time to described physical node.
Preferably, in order further from the network equipment, to distinguish switch, described device can also comprise that the second sending module and second receives detection module, as shown in Figure 5, and wherein:
Described first receives detection module, also, after the type of judging described physical node is the network equipment, by described judged result, notifies described the second sending module;
Described the second sending module, after the notice that is the network equipment in the type that receives described physical node, send request the PDU of basic bridge address to described physical node;
Described second receives detection module, receives corresponding the replying of PDU of the basic bridge of the described request address that described physical node returns, and judges according to this whether the type of described physical node is switch.
Wherein, described the second sending module, can, according to IP address, described physical node place, send request the PDU of basic bridge address to described physical node.
Preferably, in order further from the network equipment, to distinguish router, described device can also comprise that the 3rd sending module and the 3rd receives detection module, as shown in Figure 6, and wherein:
Described second receives detection module, also judge described physical node be the network equipment and be not switch after, notify described the 3rd sending module by described judged result;
Described the 3rd sending module, the type that receives described physical node be the network equipment and be not the notice of switch after, send request the PDU of IP packet Forwards Forwarding to described physical node;
The described the 3rd receives detection module, receives corresponding the replying of PDU of the described request IP packet Forwards Forwarding that described physical node returns, and judges according to this whether the type of described physical node is router.
Wherein, described the 3rd sending module, can, according to IP address, described physical node place, send request the PDU of IP packet Forwards Forwarding to described physical node.
Certainly; the present invention also can have other various embodiments; in the situation that do not deviate from spirit of the present invention and essence thereof; those skilled in the art are when making according to the present invention various corresponding changes and distortion, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
