Embodiment
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 carried out to clear, complete description, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 1 is that the embodiment of the present invention realizes the method flow schematic diagram that network strategy is upgraded; As shown in Figure 1, the method comprises:
Step 110: edge switch obtains the renewal version information of the network strategy of VSI Type, the version after the network strategy that described renewal version packets of information is drawn together described VSI Type is upgraded.
Wherein, edge switch is deployed in the edge access layer of data center network, and under virtual scene, edge switch is the network equipment nearest apart from virtualized server.VSI Type refers to virtual machine host policing type, and the VSI that belongs to same VSI Type need to carry out identical network strategy, and VSI Type can by specific sign, (English: identifier abridges: ID) represent.In various embodiments of the present invention, VSI Type ID is for identifying different VSIType.The network strategy of VSI Type refers to that all VSI that belong to this VSI Type all need the network strategy of carrying out.In Intel Virtualization Technology, VSI is different from General Physics switch ports themselves, and itself and VM are the relations coexisting, if therefore do not connect VM, VSI is non-existent.When system, (for example, vCenter) created a VM, and selected after a VSI Type for the empty network interface card of this VM, system will create a VSI on vSwitch, and gives corresponding VSI Type for it.
In actual application, described edge switch can obtain the renewal version information of the network strategy of VSI Type in several ways, only in following two kinds of modes, is illustrated in the present embodiment, but is not limited to this:
A, adopt passive receive mode to obtain: when the network strategy of VSI Type changes, policy database (for example VSI Manager or VSI Type Database) can be initiatively by the change notification of the network strategy of described VSI Type to edge switch; Described edge switch receives the notification message of described policy database, and from this notification message, extracts the renewal version information of VSI Type ID and network strategy corresponding to this VSI Type ID;
B, employing active inquiry mode are obtained: described edge switch sends version querying message to described policy database, carries the original version information of the network strategy that VSI Type ID and VSI Type ID are corresponding in described version querying message; If the network strategy of VSI Type changes described in described policy database, described policy database sends version response message to described edge switch, carries the renewal version information of the network strategy of described VSI Type in described version response message; The version response message that described edge switch sends according to described policy database can be known the renewal version information of the network strategy of described VSI Type; If the network strategy of VSI Type does not change described in described policy database, described policy database can not send version response message to described edge switch, also can send version response message to described edge switch, in this case, in this version response message, carry the original version information of the network strategy of this VSIType.
Step 120: edge switch sends to virtual switch by the renewal version information of the network strategy of described VSI Type;
Concrete, when described edge switch gets after the renewal version information of network strategy of described VSI Type, it can send to virtual switch by this renewal version information in several ways, as the following two kinds of modes in the present embodiment, but is not limited to this:
1), when described edge switch gets after the renewal version information of network strategy of described VSI Type, the VSI Tyep ID(sign corresponding according to the version after this renewal) inquire about local VSI contingency table, if there is the associated data of this VSI Type in described VSI contingency table, the renewal version information exchange of the network strategy of described VSI Type is crossed to response message and send to described virtual switch; If there is not the associated data of this VSI Type in described VSI contingency table, end operation.
2), when described edge switch gets after the renewal version information of network strategy of described VSI Type, record the renewal version information of the network strategy of this VSI Type; After receiving the request message of described virtual switch transmission, the response message that sends the renewal version information of the network strategy of carrying described VSI Type to this virtual switch, the renewal version information exchange with this by the network strategy of described VSI Type is known to described virtual switch.
Wherein it should be noted that, in the present embodiment, the response message of the renewal version information of the network strategy of carrying described VSI Type that described edge switch sends to described virtual switch can be the associated message of the solution of expansion, can certainly be other response messages, the present embodiment repeat them here.
