S110, the first message that desampler equipment sends, this first message carries the first vlan list.
S120, according to the VLAN resource requirement information of downstream node and this first vlan list, for this node distributes the second vlan list.
S130, sends the second message to this node, and this second message carries this second vlan list, so that this node is at the first network transmitting data of this second vlan list of configuration.
The first message that carries the 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, for this node distributes the second vlan list that comprises one or more VLAN, and this device sends the second message to this node, this second message carries this second vlan list, after thereby node receives this second message, second vlan list that can carry according to this second message, is disposing the first network transmitting data of the second vlan list.
Therefore, the method of the configuring virtual LAN of the embodiment of the present invention, by the VLAN resource requirement information based on node, be that node distributes VLAN, can reduce to configure difficulty, save networking cost, and the risk of avoiding a large amount of vlan informations of Dynamic Acquisition to bring to networking, thereby can significantly promote the market competitiveness of network system.
The device of the configuring virtual LAN of the embodiment of the present invention can be FSB, can be also other device, and the node of the embodiment of the present invention can be memory device or server, can be also other device, and the embodiment of the present invention is not limited to this.
In the invention process, in S120, for distributing the second vlan list, this node can comprise: from this first vlan list, select at least one VLAN to form this second vlan list.Should be understood that the VLAN in the second vlan list also can partly belong to the first vlan list or not belong to the first vlan list completely.
The method of the configuring virtual LAN of the embodiment of the present invention can be applicable to the scene of a network, also can be applicable under consolidated network framework and the scene of depositing at least two networks.When under the network architecture at this node place and while depositing second network, the S120 in method 100 specifically comprises:
According to the 3rd vlan list of the VLAN resource requirement information of this node, this first vlan list and the configuration of this second network, for this node distributes the 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 in the residue VLAN after the VLAN overlapping with the 3rd vlan list, select one or more VLAN to form this second vlan list.
Should be understood that in embodiments of the present invention, this second network is the second network in the network architecture of node place, and 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 the first vlan list, also can not belong to the first vlan list.Should also be understood that first network or second network do not represent a network, can represent respectively one or more network.
Therefore,, according to embodiments of the invention, when under consolidated network framework and while depositing at least two networks, by the VLAN different to these at least two network configuration, can avoid VLAN resource contention.
In an embodiment of the present invention, this first vlan list and the 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 required VLAN of this node, and correspondingly, the device of configuring virtual LAN can be determined the second vlan list according to the quantity of the required VLAN of node and/or ID.Should understand, the device of configuring virtual LAN is according to the VLAN resource requirement information of its downstream node and the first vlan list, can distribute the required VLAN of this node for node, also can be that 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 is 50 and 60, the device of configuring virtual LAN can comprise that ID is the 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 be determined the second vlan list that comprises two VLAN in the first vlan list, and when there is second network, two definite VLAN should not belong to the 3rd vlan list having configured in second network.Again for example, when the ID of the required VLAN of node is 70 and 80, although the VLAN that ID is 70 and 80 does not configure in second network, but the device of configuring virtual LAN can be according to out of Memory, the configuration information of for example other node etc., for this node distributes ID, be different from other two VLAN of 70 or 80, this other two VLAN should be different from the VLAN in the 3rd vlan list having configured in second network.

In FCoE network, according to the first network of the embodiment of the present invention, be storage area network (Storage Area Network is called for short " SAN "), second network is LAN (Local Area Network is called for short " LAN ").Alternatively, the first message and the second message are optical-fibre channel initiation protocol VLAN notice (Fibre Channel Initialization Protocol Virtual Local Area Network Notification is called for short " FIP VLAN Notification ") message.
In FCoE network, when increasing 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 configure difficulty, save networking cost, and the risk of avoiding a large amount of vlan informations of Dynamic Acquisition to bring to networking.In FCoE network, according to embodiments of the invention, also can be applicable under original lan network framework, increase the scene of SAN network function.
For example, node A need to be under original lan network framework, increase SAN network function, the ID of the VLAN that the original lan network of node A has configured is 1-50, if increase SAN network function, prior art needs the whole VLAN1-100 of static configuration, this may cause resource contention, so if node A increases SAN network function in prior art, need to again plan networking, or increase equipment.
And in embodiments of the present invention, when needs increase SAN network function under original lan network framework, the device of configuring virtual LAN is according to the VLAN resource requirement information of node, for node distributes VLAN, should be different from the VLAN that lan network has configured for the VLAN that node distributes, and a configuration is the VLAN that this node distributes according to the VLAN resource requirement information of node on corresponding port, thereby can solve the problem of the VLAN resource contention of SAN network and lan network.
Therefore, the method of the configuring virtual LAN of the embodiment of the present invention, by the VLAN resource requirement information based on node, be that node distributes VLAN, can reduce to configure difficulty, save networking cost, and the risk of avoiding a large amount of vlan informations of Dynamic Acquisition to bring to networking, and can solve under consolidated network framework and while 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 more fully the present invention, below in conjunction with Fig. 2, specifically describe according to the method for the configuring virtual LAN of the embodiment of the present invention.
Fig. 2 shows according to the indicative flowchart of the method for the configuring virtual LAN of the embodiment of the present invention.As shown in Figure 2, method 200 comprises:
S201, when node is under original lan network framework, while increasing SAN network function, node can send VLAN request to FCF, and this VLAN request is used for asking FCF to issue VLAN resource information.
S202, when FCF receives after the VLAN request of node transmission, sends FIP VLAN notice (Notification) message, the information that this FIP VLAN Notification message can carry whole VLAN, such as, all ID of VLAN.
S203, FSB receives the FIP VLAN Notification message that FCF sends, and is this node distribution VLAN according to the VLAN resource requirement information of node, for example, the static configuration information that this VLAN resource requirement information is node.Alternatively, VLAN resource requirement information comprises quantity and/or the ID of the required VLAN of node.For example, when the quantity of the required VLAN of node is five, FSB selects five VLAN for this node from whole VLAN, and wherein, these five VLAN are different from the VLAN that lan network has configured.For example, when the ID of the required VLAN of node is 50 and 60, FSB is that this node distribution ID is 50 and 60 VLAN.Again for example, when the ID of the required VLAN of node is 70 and 80, but when the VLAN that this ID is 70 and 80 has been configured by lan network, FSB distributes two other VLAN for this node, and this two other VLAN is different from the VLAN that lan network has configured.
S204, FSB, after node distributes VLAN, is configured to the VLAN that this node distributes on its downlink port, and revises the FIP VLAN Notification message that FCF sends, make only to carry in this message FSB and be the information of the VLAN that this node distributes, and send amended message to this node.
S205, node receives after this amended FIP VLAN Notification message, can, according to the information of carrying in message, dispose the SAN transmission over networks data of corresponding VLAN.
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 determine with its function and internal logic, and should not form any restriction to the implementation process of the embodiment of the present invention.
Therefore, the method of the configuring virtual LAN of the embodiment of the present invention, by the VLAN resource requirement information based on node, be that node distributes VLAN, can reduce to configure difficulty, save networking cost, and the risk of avoiding a large amount of vlan informations of Dynamic Acquisition to bring to networking, and can solve under consolidated network framework and while depositing at least two networks, the problem of VLAN resource contention, thus the market competitiveness of network system can significantly be promoted.
According to the method for the configuring virtual LAN of the embodiment of the present invention, also can be applicable in the FCoE network that has FSB multi-hop cascade as shown in Figure 3.
Fig. 3 shows the FCoE network architecture schematic diagram according to the embodiment of the present invention.Wherein, eNode is the node according to the embodiment of the present invention, can be memory device or server, can be also other device, and the embodiment of the present 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 be respectively 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, select corresponding VLAN.
For example, when eNode-1 need to increase SAN network function, FCF issues the message of the information of carrying whole VLAN, FSB-0 catches this message, can for it, distribute VLAN according to the VLAN resource requirement information of eNode-1, and revise the information in message, make this message only carry the information of the VLAN distributing into eNode-1, then to eNode-1, send this message, FSB-1 obtains this message, and this message is issued to eNode-1.Alternatively, the message that FSB-0 does not send FCF is modified, and directly this message is sent to FSB-1, by FSB-1, according to the VLAN resource requirement information of eNode-1, selects corresponding VLAN.
For example, when eNode-1 and eNode-2 need to increase SAN network function simultaneously, FCF issues the message of the information of carrying whole VLAN, FSB-0 catches this message, according to the VLAN resource requirement information of eNode-1 and eNode-2, be defined as the VLAN of eNode-1 and eNode-2 distribution, and revise the information in message, and make this message only carry the information into the VLAN of eNode-1 and eNode-2 distribution, then to eNode-1 and eNode-2, send this message respectively.FSB-1 catches the message that FSB-0 sends to eNode-1, and according to the VLAN resource requirement information of eNode-1, be defined as the VLAN that eNode-1 distributes, revise the information in message, make this message only carry the information of the VLAN distributing 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 according to the VLAN resource requirement information of eNode-2, be defined as the VLAN that eNode-2 distributes, and revise the information in message, make this message only carry the information of the VLAN distributing into eNode-2, then this message is issued to eNode-2.Alternatively, information in the message that FSB-0 does not send FCF is modified, and directly this message being sent to eNode-1 and eNode-2, FSB-1 and FSB-2 catch respectively this message, and according to the VLAN resource requirement information of eNode-1 and eNode-2, select corresponding VLAN respectively.
Should be understood that above this this eNode and quantity and the connected mode of FSB, just exemplary illustrated, should not form any restriction to the embodiment of the present invention.
