Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the premise not making creative work, all should belong to the scope of protection of the invention.
In virtual network, VXLAN tunnel destination node VTEP (VXLANTerminalEndPoint) is the functional module on server in VXLAN network, for receiving the two layer message into tunnel, and two layer message is packaged into VXLAN message, at tunnel destination node, the message of the VXLAN after encapsulation is reduced to two layer message, namely VTEP is responsible for encapsulation and the decapsulation in VXLAN tunnel, to realize being forwarded by the data of network between different virtual network.
VTEP is the node that a virtual network and other virtual network connect transmission data each other, it is possible to be a chip on a server or a functional module, it is also possible to be a chip in a switching equipment or a functional module.Above-mentioned virtual network can be the virtual network of certain area, and multiple virtual networks are connected with each other the forwarding with data by real-time performance.
As it is shown in figure 1, be embodied as example on the server with VTEP, include central processor CPU 101, internal memory 102 and tunnel destination node VTEP103 in the server.VTEP103 realizes its function under the control of central processing unit.In the embodiment of the present invention, VETP can also realize its function at miscellaneous equipment (such as switching equipment) or independent equipment, repeats no more.
Carried out the forwarding of data below by network for three virtual networks, equipment and the method transmit data in a kind of VXLAN of the embodiment of the present invention illustrate.
As in figure 2 it is shown, three virtual networks forward respectively through the respective VTEP data realized between different virtual network.Fictitious plan network in the virtual network being designated 4096 of VTEP1 management includes vlan10, vlan20 and vlan30；Sub-virtual network in the virtual network being designated 4096 of VTEP2 management also includes vlan10, vlan20 and vlan30；Fictitious plan network in the virtual network being designated 4096 of VTEP3 management includes vlan10, vlan20 and vlan30～50.
As shown in Figure 2, carried out data transmission by network with the user in the same virtual network in the virtual network that virtual process identifications is 4096 of VTEP3 management if the user in the virtual network that virtual process identifications is 4096 of VTEP1 management requires over network, needing to set up a vlan30 in the VTEP3 virtual network managed is the sub-virtual network identified so that the data that the vlan30 from VTEP1 passes over can be forwarded in purpose virtual network by VTEP3.But, prior art can exist mark vlan30 occupied situation in the VTEP3 virtual network managed, namely vlan30 is shared by sub-virtual network corresponding to other business, when so the vlan30 from VTEP1 is sent to VTEP3, can be transmitted to by VTEP3 and be designated sub-virtual network corresponding to vlan30, and the sub-virtual network of purpose that the vlan30 that this sub-virtual network is not VTEP1 management to send, cause that the user in same sub-virtual network cannot realize intercommunication, network organizing underaction, affects the forwarding of user data.
The embodiment of the present invention is by changing the configuration in VTEP3, using sub-virtual network corresponding as the sub-virtual network being designated vlan30 managed with VTEP1 for the sub-virtual network of business unassigned in virtual network 3, and set up mapping table, when data forward, forward the data in the sub-virtual network of correspondence.Concrete step as shown in Figure 3:
The VTEP of the step S1: the first virtual network receives configuration order, and described configuration order arranges the corresponding relation identified between the sub-virtual process identifications in the second virtual network of the sub-virtual network in the first virtual network；
Concrete, it is possible to by user command row, or special configuration management tool (such as VXLANManager), issue described configuration order.
Configuration fame and gain is issued by order line for user, user is by the vlan (LocalCustomerVlan) of configuration interface input local user, interconnection protocol IP address (RemotePeerIp) between the network of the vlan (RemoteCustomerVlan) of remote subscriber and the VTEP of remote subscriber place virtual network.Such as, in above-mentioned Fig. 2, VTEP3 place virtual network is the first virtual network, the virtual network at VTEP2 place is the second virtual network, due in the VTEP3 virtual network being designated 4096 managed, sub-virtual network vlan30 is occupied, require over configuration, unappropriated sub-virtual network (such as vlan4094) is configured to the sub-sub-virtual network corresponding for virtual network vlan30 in the virtual network being designated 4096 managed with VTEP1.
Based on examples detailed above, above-mentioned LocalCustomerVlan can be the sub-virtual network vlan of unallocated business in the virtual network at VTEP3 place in Fig. 2, for instance vlan4094；RemoteCustomerVlan can be sub-virtual network corresponding for vlan30 in the VTEP1 virtual network managed；RemotePeerIp can be the IP address of VTEP1.Configuration order can be as follows:
[Server3-VXLAN-VNI4096] customervlan4094mapping-toremoteip10.10.10.1remotevlan30, the type of this message can be: vxlan-customer-vlan-mapping, this type of message carries within the message, for identifying this message for configuring the message of the corresponding relation of sub-virtual network.
S2: the message that the parsing of the VTEP of described first virtual network issues, if type of message is vxlan-customer-vlan-mapping, determine the corresponding relation between the Vlan mark in the first virtual network and the Vlan mark in second area according to described message, and this corresponding relation is saved in fictitious plan network mapping table.
Concrete, VTEP3 according to described vxlan-customer-vlan-mapping message, can call vxlan-customer-vlan-mapping message processing function, extracts following parameter from this message:
VNIID, RemotePeerIp, RemoteCustomerVlan and LocalCustomerVlan.Wherein, VNI is VXLAN network identifier, and VNIID is the ID of VXLAN network identifier.
Structure is with VNIID, RemotePeerIp, RemoteCustomerVlan are Key, LocalCustomerVlan is the hash table of Result, this list item is added in the fictitious plan network mapping table of VTEP3, and this mapping table is stored in the internal memory of equipment at VTEP3 place.
Corresponding relation between sub-virtual process identifications in above-mentioned first virtual network and the sub-virtual process identifications in the second virtual network can be as shown in table 1:
Table 1
Wherein, VNIID represents the mark of virtual network, for instance in Fig. 2, the mark 4096, RemotePeerIp of virtual network represents the IP address of VTEP, for instance in Fig. 2, the IP address that IP address is 10.10.10.1, VTEP2 of VTEP1 is 20.20.20.2；RemoteCustomerVlan represents sub-virtual process identifications corresponding in the virtual network of far-end, for instance the vlan30 in vlan30 or VTEP2 in VTEP1；The sub-virtual process identifications that LocalCustomerVlan is corresponding with this locality, for instance in Fig. 2, the sub-virtual process identifications vlan4094 of unallocated business in VTEP3.
Optionally, for ensureing the reliability of corresponding relation, fictitious plan network mapping table can also be backed up in realtime in the alternate devices such as baseboard management controller the mounted internal memory of BMC by the method that the embodiment of the present invention provides.Under server, after electricity, the list item in host memory recovers to be recovered by this alternate device.
Configuration information is sent the VTEP to the second virtual network specified by VTEP signaling by S3, the VTEP of described first virtual network, and signalling path and message format can be as shown in Figure 3.
VTEP3 (can be the signaling distribution unit in VTEP3) inserts corresponding value in each field of vxlancustomervlanmapping message, the value that such as each field shown in table 1 is corresponding, and the vxlancustomervlanmapping after filling is sent to VTEP1 and VTEP2.Such as, to in the VTEP1 vxlancustomervlanmapping message sent, insert 4096 in VNIID field, insert 10.10.10.1 in RemotePeerIp field, insert 30 in RemoteCustomerVlan field, insert 4094 in LocalCustomerVlan field.To in the VTEP2 vxlancustomervlanmapping message sent, insert 4096 in VNIID field, insert 20.20.20.2 in RemotePeerIp field, insert 30 in RemoteCustomerVlan field, insert 4094 in LocalCustomerVlan field.
After the VTEP of the S4: the second virtual network receives the described message of the VTEP of the first virtual network, described corresponding relation is saved in the fictitious plan network mapping table of VTEP of the second virtual network, and fictitious plan network mapping table is saved in the host memory of this locality.Fictitious plan network mapping table in second virtual network can be as shown in table 2:
Table 2
Concrete, it is possible to it is the signaling reception unit of the VTEP of the second virtual network, receives the VTEP of the described first virtual network message sent.After the signaling reception unit of the VTEP of the second virtual network receives the far-end VTEP message sended over, first the legitimacy of verification message, then type of message is resolved, for VXLAN_CUSTOMER_VLAN_MAPPING message, call the process function of the Vlan mapping in signaling processing component and be further processed.Vlan mapping process function from message structure body one by one field extract information, create with VNIID, LocalIp, LocalCustomerVlan is Key, RemoteCustomerVlan is the hash table of Result, being added to by this list item in the VLAN mapping table of VTEP parts, this mapping table is similarly positioned in host memory.
