First message that carries first vlan list that the device desampler equipment of configuring virtual LAN sends; This device is according to the VLAN resource requirement information of its downstream node; Distribute second vlan list that comprises one or more VLAN for this node; And this device sends second message to this node, and this second message carries this second vlan list, thereby node receives after this second message; Second vlan list that can carry according to this second message is disposing the first transmission over networks data of second vlan list.
Therefore; The method of the configuring virtual LAN of the embodiment of the invention; Through the VLAN resource requirement information based on node is that node distributes VLAN, can reduce to dispose difficulty, practices thrift networking cost; And avoid dynamically obtaining the risk that lot of V LAN information is brought to networking, thereby can significantly promote the market competitiveness of network system.
The device of the configuring virtual LAN of the embodiment of the invention can be FSB, also can be for other install, and the node of the embodiment of the invention can be memory device or server, also can be for other install, the embodiment of the invention is not limited to this.
In the present invention implements, for distributing second vlan list, this node can comprise among the S120: from this first vlan list, select at least one VLAN to form this second vlan list.Should be understood that the VLAN in second vlan list also can partly belong to first vlan list or not belong to first vlan list fully.
The method of the configuring virtual LAN of the embodiment of the invention can be applicable to the scene of a network, also can be applicable under the consolidated network framework and the scene of depositing at least two networks.When under the network architecture at this node place and when depositing second network, the S120 in the method 100 specifically comprises:
According to the 3rd vlan list of VLAN resource requirement information, this first vlan list and this second network configuration of this node, for this node distributes second vlan list, the VLAN in this second vlan list is different from the VLAN in the 3rd vlan list.For example, from this first vlan list, remove among the residue VLAN behind the VLAN that overlaps with the 3rd vlan list, select one or more VLAN to form these second vlan lists.
Should be understood that in embodiments of the present invention this second network is second network in the network architecture of node place, this node can have Network in this second network, also can not have Network.Should be understood that the 3rd vlan list comprises one or more VLAN, all or part of of the 3rd vlan list can belong to first vlan list, also can not belong to first vlan list.Should also be understood that first network or second network do not represent a network, can represent one or more network respectively.
Therefore, according to embodiments of the invention, when under the consolidated network framework and when depositing at least two networks, the VLAN through different to these at least two network configuration can avoid the VLAN resource contention.
In an embodiment of the present invention, this first vlan list and second vlan list specifically comprise the sign ID of VLAN, or are used to indicate the out of Memory of VLAN, such as the title of VLAN, numbering etc.
Alternatively, the VLAN resource requirement information of node comprises quantity and/or the ID of the VLAN that this node is required, and correspondingly, the device of configuring virtual LAN can be confirmed second vlan list according to quantity and/or the ID of the required VLAN of node.Should understand; The device of configuring virtual LAN is according to the VLAN resource requirement information and first vlan list of its downstream node; Can distribute the required VLAN of this node for node; Also can be that the node distribution is different from the required VLAN of this node according to other information, or part be different from the required VLAN of this node.
For example, when the ID of the required VLAN of node was 50 and 60, the device of configuring virtual LAN can comprise that ID is second vlan list of two VLAN of 50 and 60 for node distributes.For example; When the quantity of the required VLAN of node is two; The device of configuring virtual LAN can confirm to comprise second vlan list of two VLAN in first vlan list, when having second network, two definite VLAN should not belong to the 3rd vlan list that has disposed in second network.Again for example; When the ID of the required VLAN of node is 70 and 80; In second network, do not dispose though ID is 70 and 80 VLAN, the device of configuring virtual LAN can be according to out of Memory, for example configuration information of other node etc.; Be different from other two VLAN of 70 or 80 for this node distributes ID, this other two VLAN should be different from the VLAN in the 3rd vlan list that has disposed in second network.

In the FCoE network; When increasing the SAN network function, the device of configuring virtual LAN is that node distributes VLAN according to the VLAN resource requirement information of node, thereby can reduce to dispose difficulty; Practice thrift networking cost, and avoid dynamically obtaining the risk that lot of V LAN information is brought to networking.In the FCoE network, also can be applicable under original lan network framework according to embodiments of the invention, increase the scene of SAN network function.
For example, node A need increase the SAN network function under original lan network framework; The ID of the VLAN that the original lan network of node A has disposed is 1-50, if increase the SAN network function, prior art needs the whole VLAN1-100 of static configuration; This possibly cause resource contention;, need plan networking again, or increase equipment so if node A increases the SAN network function in the prior art.
And in embodiments of the present invention; When needs increase the SAN network function under original lan network framework; The device of configuring virtual LAN for node distributes VLAN, should be different from the VLAN that lan network has disposed according to the VLAN resource requirement information of node for the VLAN that node distributes; And on corresponding ports, only dispose the VLAN that distributes for this node according to the VLAN resource requirement information of node, thereby can solve the problem of the VLAN resource contention of SAN network and lan network.
Therefore, the method for the configuring virtual LAN of the embodiment of the invention is that node distributes VLAN through the VLAN resource requirement information based on node; Can reduce to dispose difficulty; Practice thrift networking cost, and avoid dynamically obtaining the risk that lot of V LAN information is brought to networking, and can solve under the consolidated network framework and when depositing at least two networks; The problem of VLAN resource contention, thus the market competitiveness of network system can significantly be promoted.
In order to understand the present invention more fully, will combine Fig. 2 to specifically describe method below according to the configuring virtual LAN of the embodiment of the invention.
Fig. 2 shows the indicative flowchart according to the method for the configuring virtual LAN of the embodiment of the invention.As shown in Figure 2, method 200 comprises:
S201, when node under original lan network framework, when increasing the SAN network function, node can send the VLAN request to FCF, this VLAN request is used to ask FCF to issue the VLAN resource information.
S202 after FCF receives that the VLAN of node transmission asks, sends FIP VLAN notice (Notification) message, the information that this FIP VLAN Notification message can carry whole VLAN, such as, the ID of whole VLAN.
S203, FSB receives the FIP VLAN Notification message that FCF sends, and distributes VLAN according to the VLAN resource requirement information of node for this node, and for example, this VLAN resource requirement information is the static configuration information of node.Alternatively, the VLAN resource requirement information comprises quantity and/or the ID of the VLAN that node is required.For example, when the quantity of the required VLAN of node was five, FSB selected five VLAN for this node from whole VLAN, and wherein, these five VLAN are different from the VLAN that lan network has disposed.For example, when the ID of the required VLAN of node was 50 and 60, FSB was 50 and 60 VLAN for this node distribution ID.Again for example, when the ID of the required VLAN of node is 70 and 80, but this ID is 70 and 80 VLAN when having been disposed by lan network, and then FSB is that this node distributes two other VLAN, and this two other VLAN is different from the VLAN that lan network has disposed.
S204; FSB is that node distributes after the VLAN, on its downlink port, is configured to the VLAN that this node distributes, and revises the FIP VLAN Notification message that FCF sends; Make and only carry the information of FSB in this message, and send amended message to this node for the VLAN of this node distribution.
S205, node can dispose the SAN transmission over networks data of corresponding VLAN according to the information of carrying in the message after receiving this amended FIP VLAN Notification message.
Should understand; In various embodiment of the present invention; The size of the sequence number of above-mentioned each process does not also mean that the priority of execution sequence, and the execution sequence of each process should be definite with its function and internal logic, and should not constitute any qualification to the implementation process of the embodiment of the invention.
Therefore, the method for the configuring virtual LAN of the embodiment of the invention is that node distributes VLAN through the VLAN resource requirement information based on node; Can reduce to dispose difficulty; Practice thrift networking cost, and avoid dynamically obtaining the risk that lot of V LAN information is brought to networking, and can solve under the consolidated network framework and when depositing at least two networks; The problem of VLAN resource contention, thus the market competitiveness of network system can significantly be promoted.
Method according to the configuring virtual LAN of the embodiment of the invention also can be applicable in the FCoE network that has the FSB multi-hop cascade as shown in Figure 3.
Fig. 3 shows the FCoE network architecture sketch map according to the embodiment of the invention.Wherein, eNode is the node according to the embodiment of the invention, can be memory device or server, also can be for other install, and the embodiment of the invention is not limited to this.
As shown in Figure 3, for the VLAN resource requirement of eNode-1, eNode-2, eNode-3, eNode-4, can select corresponding VLAN by FSB-0 and/or FSB-1, FSB-0 and/or FSB-2, FSB-0 and/or FSB-3, FSB-0 and/or FSB-4 for it respectively.
For example, when eNode-1 need increase the SAN network function, FCF issued the message of the information of carrying whole VLAN; FSB-0 catches this message, can distribute VLAN for it according to the VLAN resource requirement information of eNode-1, and revise the information in the message; Make this message only carry the information of the VLAN that distributes into eNode-1; Send this message to eNode-1 then, FSB-1 obtains this message, and this message is issued to eNode-1.Alternatively, FSB-0 does not make amendment to the message that FCF sends, and directly this message is sent to FSB-1, selects corresponding VLAN by FSB-1 according to the VLAN resource requirement information of eNode-1.
For example; When eNode-1 and eNode-2 need increase the SAN network function simultaneously, FCF issued the message of the information of carrying whole VLAN, and FSB-0 catches this message; Confirm as the VLAN of eNode-1 and eNode-2 distribution according to the VLAN resource requirement information of eNode-1 and eNode-2; And the information in the modification message, make this message only carry information into the VLAN of eNode-1 and eNode-2 distribution, send this message to eNode-1 and eNode-2 respectively then.FSB-1 catches the message that FSB-0 sends to eNode-1; And, confirm as the VLAN that eNode-1 distributes according to the VLAN resource requirement information of eNode-1, revise the information in the message; Make this message only carry the information of the VLAN that distributes into eNode-1, then this message is issued to eNode-1; Correspondingly; FSB-2 catches the message that FSB-0 sends to eNode-2; And, confirm as the VLAN that eNode-2 distributes, and revise the information in the message according to the VLAN resource requirement information of eNode-2; Make this message only carry the information of the VLAN that distributes into eNode-2, then this message is issued to eNode-2.Alternatively; FSB-0 does not make amendment to the information in the message of FCF transmission; And directly this message being sent to eNode-1 and eNode-2, FSB-1 and FSB-2 catch this message respectively, and select corresponding VLAN according to the VLAN resource requirement information of eNode-1 and eNode-2 respectively.
Should be understood that above this this eNode and quantity and the connected mode of FSB, just exemplary illustrated should not constitute any qualification to the embodiment of the invention.
Therefore, the method for the configuring virtual LAN of the embodiment of the invention is that node distributes VLAN through the VLAN resource requirement information based on node; Can reduce to dispose difficulty; Practice thrift networking cost, and avoid dynamically obtaining the risk that lot of V LAN information is brought to networking, and can solve under the consolidated network framework and when depositing at least two networks; The problem of VLAN resource contention, thus the market competitiveness of network system can significantly be promoted.
