Embodiment
Fig. 1 is the application system Organization Chart of FCoE network linking management method embodiment of the present invention, as shown in Figure 1, ENode1～ENode6 is a plurality of FCoE nodes (FCoE Node) in the FCoE network, and this FCoE node for example can be equipment such as server, memory or user terminal; Can realize communication by the enhancement mode Ethernet switch in the harmless Ethernet (Lossless Ethernet) between each FCoE node.In the embodiments of the invention, also be provided with management server (Manager Server), each FCoE node also can be by enhancement mode Ethernet switch and the management server communication in the harmless Ethernet.
In the embodiments of the invention, be by safeguarding linking status by periodical exchange Beacon between management server and each the FCoE node, each FCoE node only needs to detect with linking of management server and gets final product, and do not need as prior art must with the FCoE network in all FCoE nodes all detect by Beacon and link, wherein Beacon is a kind of data message of special purpose, be used for safeguarding in the mode of heartbeat the network linking state of the equipment that sends this data message, for brevity, abbreviate the data message of this special purpose as Beacon in this manual; And, be by management server the node of FCoE network for example to be changed the event notice of certain node break link to give the FCoE node, the FCoE node does not need oneself to detect again, and has saved the time of FCoE node yet, can make the FCoE node more be absorbed in other business.
Below in conjunction with Fig. 1, FCoE network linking management method of the present invention is elaborated:
Embodiment one
Fig. 2 is the schematic flow sheet of FCoE network linking management method one embodiment of the present invention, and the method for present embodiment is that the FCoE node is carried out, and as shown in Figure 2, this method can comprise:
201, periodically send Beacon to management server, and periodically start the Beacon that timer detects the management server transmission, the Beacon that sends according to described management server determines that management server is at the linking status of FCoE network;
In the present embodiment, pass through periodical exchange Beacon between each FCoE node and the management server, detect the linking status of the other side in the FCoE network, described linking status is normal or off-line, for example, if certain FCoE node link state is normal, then this FCoE node can regularly send Beacon, management server can receive this Beacon, can determine accordingly that the normal, chain of FCoE node is connected on network; If certain FCoE node link state is off-line, then this FCoE node no longer sends Beacon, and management server can not receive the Beacon of this FCoE node, can determine FCoE node and network break link accordingly.In like manner, the FCoE node also can be judged the linking status of management server in the FCoE network according to the Beacon of management server transmission.
Concrete, each FCoE node can periodically send Beacon to management server, carry the node identification of this FCoE node among this Beacon, be connected on the FCoE network to be used for this FCoE node normal, chain of notice management server, as long as management server can receive the Beacon that this FCoE node sends, just can determine that this FCoE node normal, chain is connected on the FCoE network, namely the linking status of FCoE node is normal; So management server just can be judged the linking status of all FCoE nodes by detecting the Beacon whether receive each FCoE node, for example be normally or off-line.
Simultaneously, each FCoE node also can periodically detect the Beacon that management server sends, whether normal, chain is connected on the FCoE network to judge management server, this Beacon is that management server sends in the FCoE Web broadcast, wherein also can carry the sign of management server, so that the FCoE node is the Beacon that management server sends by this sign identification.For example, the FCoE node can start timer, if in the Preset Time that timer is set, receive the Beacon that management server sends, can determine that then the management server normal, chain is connected on the FCoE network, be that the linking status of management server is for normal, and the renewal timer, wait for receiving the Beacon that next time sends; If the Beacon that sends of receiving management server not in Preset Time shows that then management server may leave the FCoE network, i.e. management server and FCoE network break link, the linking status of this management server is off-line.
202, receive described management server in the node change notification message of described FCoE Web broadcast, this node change notification message is carried the nodal information of the FCoE node that the linking status in the FCoE network changes;
The nodal information of the FCoE node that the linking status in the described FCoE network changes, mainly comprise two kinds of situations, a kind of is the nodal information that newly adds the FCoE node of this FCoE network, the linking status linking status that refers to the FCoE node that changes of this moment is changed to normally by off-line, namely this FCoE node has just been set up with the FCoE network and has been linked, and described nodal information comprises node identification and link foundation sign; The node identification and the linking status that have shown this node; Another kind is the nodal information of the FCoE node that leaves from the FCoE network, this moment linking status change refer to the FCoE node linking status by normally changing to off-line, namely this FCoE node just with FCoE network break link, described nodal information comprises that node identification and link disconnect and identifies.
In the present embodiment, variation has taken place with respect to prior art in the mode of the linking status of each node of FCoE node detection in the FCoE network.
Concrete, in the prior art, each FCoE node need be broadcasted Beacon in the FCoE network, detects to confirm linking status between the node so that each FCoE node all carries out Beacon mutually; And in the present embodiment, each FCoE node only needs to adopt between mode of unicast and the management server to detect to link by Beacon and gets final product, the linking status of other nodes is to be determined and be notified to the FCoE node by the Beacon that management server sends by detection node, for example, management server is all normal with linking of FCoE node A and FCoE Node B, represents that then the link between FCoE node A and the FCoE Node B is also normal.
For example, the mode that detects linking status between management server and the FCoE node illustrates in 201, linking under the normal situation between FCoE node and management server, management server just can be given all nodes with the linking status change notification of the FCoE node in the FCoE network.Such as, when management server does not receive the Beacon of FCoE node A transmission in Preset Time, determine FCoE node A break link, then to whole FCoE Web broadcast node change notification message, node identification and the link of carrying FCoE node A in this message disconnect sign, to notify other FCoE nodes FCoE node A break link.
Because the FCoE node only needs and management server between mutual Beacon, with respect to prior art at FCoE Web broadcast Beacon, alleviated the node burden greatly, the FCoE node can be absorbed in the main business of oneself, and, for the FCoE network, because Beacon reduces, thereby also reduced the network bandwidth that Beacon takies, promoted network performance.
203, according to the nodal information of the FCoE node in the described node change notification message, upgrade local neighbor table;
Wherein, safeguard on each FCoE node a neighbor table is arranged, this neighbor table is used for for example node identification of information that record can set up other nodes that link with this FCoE node, wherein, only the linking status of the other side's node in the FCoE network is under the normal condition in neighbor table, this FCoE node just can be set up with the other side's node and link, and such as can both normally sending beacon separately, the phase mutual energy receives the information that the other side sends; When this FCoE node receives the node change notification message of management server broadcasting, will upgrade local neighbor table according to the nodal information of the FCoE node in this node change notification message.
For example, leaving from the FCoE network for certain FCoE node is that the linking status of FCoE node is by the situation that normally changes to off-line, the FCoE node that receives the node change notification message will be inquired about its local neighbor table, if the node identification of the FCoE node of this break link is arranged in the neighbor table, it for example is FCoE node A break link, then the node identification of this FCoE node A is deleted from the neighbor table of this locality, shown the disconnection that links with this FCoE node A; If the node identification of this FCoE node A not in the disconnection neighbor table then shows locally not link with regard to not existing originally with this FCoE node A, then can keep neighbor table constant.
Again for example, the situation that newly adds this FCoE network for certain FCoE node, the FCoE node that receives the node change notification message will be inquired about its local neighbor table, if there is not the node identification of this new adding FCoE node in the neighbor table, and this locality is want to link with this new adding FCoE node foundation, then can be added in the local neighbor table by the new node identification that adds the FCoE node.
Need to prove, in the present embodiment, when certain FCoE node breaks link from the FCoE network, be to be notified to each other FCoE node by management server, because in the FCoE network, each FCoE node only with the mutual Beacon of management server clean culture, be not mutual Beacon's alternately between each FCoE node, have only management server just to detect whether break link of certain FCoE node, so can only give each node in the FCoE network with the event notice of node break link by management server.And for the event that increases certain FCoE node in the FCoE network newly, be optional by management server notice, management server can be broadcast to other nodes when detecting certain FCoE node and be the node that increases newly; Perhaps, the FCoE node that increases newly also can the Claim flow process before sending Beacon in oneself node identification broadcast announcement to other nodes in the network.

Fig. 3 is the schematic flow sheet of another embodiment of FCoE network linking management method of the present invention, and the method for present embodiment is that management server is carried out, and as shown in Figure 3, this method can comprise:
301, to each FCoE node periodic broadcast Beacon of FCoE network, and periodically start timer and detect the Beacon that the FCoE node sends, the Beacon that sends according to described FCoE node determines the linking status of described FCoE node in the FCoE network;
Wherein, detect the other side at the linking status of FCoE network by periodical exchange Beacon between management server and each the FCoE node, management server will be periodically to whole FCoE Web broadcast Beacon, and will detect the Beacon that each FCoE node periodically sends.
For example, management server is when detecting the Beacon of FCoE node transmission, also detect by starting timer, if in the Preset Time that timer is set, receive the Beacon that the FCoE node sends, show that then this FCoE node is normal in the FCoE network linking; Otherwise, show that this FCoE node disconnects in the FCoE network linking.
When 302, in determining described FCoE network, having the FCoE node that linking status changes, to described FCoE Web broadcast node change notification message, carry the nodal information of the FCoE node that described linking status changes;
Wherein, management server is determined the FCoE node when the linking status of FCoE network changes at the Beacon that sends according to the FCoE node, then can notify the event of this linking status variation to the FCoE Web broadcast.For example, when the FCoE node newly added the FCoE network, the linking status of this node was changed to normally by off-line; Perhaps, when the FCoE node left the FCoE network, the linking status of this node was by normally becoming off-line.
For example, suppose that management server is by detecting the Beacon of FCoE node, find for example FCoE node A break link of certain FCoE node, be that management server does not receive the Beacon that FCoE node A sends in the Preset Time that timer is set, then management server will be to FCoE Web broadcast node change notification message, node identification and the link of carrying FCoE node A disconnect sign, with the break link of this FCoE node of other FCoE nodes A in the informing network.
Other FCoE nodes in the FCoE network, the node change notification message that will send according to management server is deleted the node identification of the FCoE node A of break link from its neighbor table; Described other FCoE nodes are nodes that the linking status in the described FCoE network does not change.
To carry out more specific description to the FCoE network linking management method of present embodiment below, and, will divide two embodiment respectively the workflow separately of FCoE node, management server to be described:
Embodiment three
Fig. 4 is the workflow diagram of the management server among the another embodiment of FCoE network linking management method of the present invention, and as shown in Figure 4, the execution flow process of management server is as follows:
401, management server is finished initial work;
Wherein, described initialization mainly refers to management server and powers on, and the every preparation before finishing the work enters operating state; And, can configure the sign of this management server in advance at management server, for example, the address that can dispose this management server identifies as it.
402, management server is periodically to FCoE Web broadcast Beacon;
Wherein, the transmission cycle of Beacon can preset, and for example, sends a Beacon every one minute.The Beacon transmission cycle here adopts usual manner to get final product, and Beacon also is conventional form, just the sign of having carried management server therein.
403, management server is waited for the information that the FCoE node sends that receives;
Wherein, here 403 and 402 be actually that management server carries out simultaneously, namely management server can wait for receiving the information that the FCoE node sends do not have sequence limit between these two steps simultaneously to FCoE Web broadcast Beacon.
The information that described FCoE node sends for example is Claim information or the Beacon that the FCoE node sends; Concrete, each FCoE node all can generate a node identification that is used for sign this node self at first at random when adding the FCoE network at first, and order is carried out Probe flow process, Claim flow process and Beacon flow process successively; Wherein, described Probe, Claim and Beacon are respectively a kind of data messages of special purpose, and the flow process that sends this data message can be called flow process that should data message, and for example, what send in the Beacon flow process is this data message of Beacon;
The Probe flow process: this FCoE node broadcasting Probe in the network applies for information, and carries the node identification that it generates at random, and whether inquiry has other nodes to use this node identification; If have, then used the node of this node identification to return push-notification-answer to this FCoE node, then this FCoE node will regenerate another node identification; Otherwise if there are not other nodes to use, then this FCoE node can continue to carry out the Claim flow process;
The Claim flow process: this FCoE node is broadcasted Claim in the FCoE network, carry the node identification that it generates at random, and other nodes in the informing network oneself have used this node identification, and continues to carry out the Beacon flow process;
Beacon flow process: in the present embodiment, this Beacon flow process refers to, this FCoE node periodically adopts the mode of clean culture to send the data message Beacon that is used for the network linking state of heartbeat mode service equipment to management server, carry the node identification that oneself uses among this Beacon, so that management server determines that according to this Beacon linking status is normal.
In the present embodiment, management server is in joining this FCoE network the time, in fact its Probe that might receive the transmission of FCoE node applies for information or Claim message or Beacon, but, only when sending Claim, the FCoE node shows just that this node formally brought into use the node identification that wherein carries, so the management server emphasis is to receive Claim message or Beacon, and be for further processing according to the node identification that carries among this Claim message or the Beacon, such as this node identification of record.When management server added the FCoE network, the FCoE node was in the Claim flow process stage, and what then management server received will be Claim message; When management server added the FCoE network, the FCoE node was in the Beacon stage, and that then management server receives will be Beacon.
In addition, in this step, management server also might receive the query messages that the FCoE node sends, such as being the query messages that newly adds the FCoE node transmission of this FCoE network, be used for inquiry and whether have this management server, carry the sign (each FCoE node is all known the sign of management server, for example might be to be pre-configured on the FCoE node) of management server in this query messages.Then to FCoE node echo reply message, be there is this management server in management server so that the FCoE node is known when receiving this query messages.After echo reply message, management server will then be waited for the information that the FCoE node sends that receives, and this information for example is Beacon or the Claim that the FCoE node sends.
404, management server receives the Beacon of FCoE node transmission or the data message Claim that is used for carrying out the identity statement, carries the node identification of described FCoE node;
Wherein, aforesaid, the information that FCoE node that management server receives sends may be Claim message, may be Beacon also, depends on that FCoE node self is current to be in which flow process stage.No matter but be which flow process, all can carry the node identification of this FCoE node among Beacon or the Claim.
405, whether management server decision node sign stores in the neighbor table of this locality;
Wherein, management server is will be responsible for by detecting the Beacon of each FCoE node, determine the linking status of FCoE node, so management server also can himself arrange a neighbor table, the node identification of the normal FCoE node of record link in this neighbor table; Described link normally refers to, and this management server can receive the Beacon of this FCoE node, has represented that also this FCoE node also can communicate by letter with other nodes in the network.
In the present embodiment, if management server queries learns that this node identification is not stored, and shows then that for management server this is a FCoE node that increases newly in neighbor table, then continue to carry out 406; If this node identification is stored in neighbor table, then continue to carry out 407;
406, management server records node identification in neighbor table, and continues to carry out 407;
407, management server starts timer, begins to wait for the Beacon that receives the transmission of FCoE node;
Wherein, for the situation that node identification in 405 is not stored in neighbor table, management server record in neighbor table after the node identification, namely starts timer, begins to wait for the Beacon that receives the transmission of FCoE node;
The situation of in neighbor table, having stored for node identification in 405, should be that the FCoE node is in the Beacon stage, and management server has also started timer, this moment is when receiving this Beacon, be that the hypothesis management server is to have received this Beacon in the Preset Time of timer, then this moment, management server was to restart timer 407, was equivalent to upgrade timer and restarted timing, waited for the Beacon that receives next time.
No matter be which kind of above-mentioned situation, management server all will continue to carry out 408 after timer starts; Certainly, the situation of having stored in neighbor table for above-mentioned node identification when in fact management server receives the Beacon that the FCoE node sends in 404, is at first to carry out 408 judgement.
408, management server judges whether the Beacon that the overtime FCoE of not receiving node sends;
Wherein, management server all can be carried out the whether judgement of the Beacon that the overtime FCoE of not receiving node sends after starting timer;
Concrete, timer has individual Preset Time, if when the no show still of this Preset Time, management server has just received the Beacon that the FCoE node sends, and then management server just can obtain above-mentioned judged result and is: deny, namely do not have overtime not receiving; Then management server will be carried out the above-mentioned timer that restarts, and wait for the Beacon that receives next time; The Beacon that this wait receives next time is equivalent to be back to 403.
If when the Preset Time of timer arrives, management server does not receive the Beacon that the FCoE node sends yet, and then management server just can obtain above-mentioned judged result and is: be, i.e. overtime not receiving; Then management server just can determine accordingly that this FCoE node has lost link, will continue to carry out 409.
409, management server is removed the node identification of the FCoE node in its neighbor table;
Wherein, aforesaid, what management server recorded in neighbor table is the node identification of the FCoE node of normal link, so when the link of determining the FCoE node in 408 has disconnected, then need this node identification is deleted from neighbor table.
410, management server is to FCoE Web broadcast node change notification message, and node identification and link that described node change notification message is carried the described FCoE node of break link disconnect sign;
Wherein, management server is in the reception condition of passing through Beacon between detection and the FCoE node, when obtaining this FCoE node break link, need this event broadcast to other nodes in the whole FCoE network, so that other FCoE nodes are known this FCoE node break link; So node identification and the link that will carry the FCoE node in the node change notification message disconnect sign.
Other FCoE node just can be inquired about the neighbor table of himself according to this node change notification message, and whether the node identification that carries in the decision node change notification message has storage in its neighbor table; If not storage shows that himself and the FCoE node of this break link just cannot set up linking relationship originally, so can ignore the node change notification message, the maintenance neighbor table is constant; If storage is arranged, then show himself with the FCoE node of this break link before can set up and link, need to upgrade neighbor table now, the node identification of the FCoE node of break link is deleted from neighbor table.
Further, management server records in 406 after the node identification of the FCoE node that increases newly, also can continue to carry out 411;
411, management server is to FCoE Web broadcast node change notification message, and described node change notification message is carried node identification and the link of the node that increases newly and set up sign;
Wherein, the FCoE node that this increases newly is for management server, in its neighbor table before not storage; If being management server, learns by receiving Claim message this FCoE node, then this node is really to increase newly to this FCoE network, if and this FCoE node to be management server learn by receiving Beacon, then this node is to have suffered at this FCoE network, just is notified to management server first.
Therefore, management server is to other node broadcasts node change notification message the time, and the FCoE node that this increases newly is for other nodes, may be stored in the neighbor table of other nodes self or storage as yet; If stored, it is constant that then other nodes can keep its neighbor table; If do not store as yet, need set up under the situation about linking with this FCoE node that increases newly at other nodes self, other nodes can be added into the node identification of this FCoE node in its neighbor table, set up under the situation about linking at the FCoE node that other nodes self do not need to increase newly with this, also can keep its neighbor table constant.
For other above-mentioned nodes when receiving the node change notification message, stored the situation of the node identification of the FCoE node that increases newly in its neighbor table, also might be other nodes obtains and storage when receiving the Claim message of this FCoE node that increases newly before; Because in the present embodiment, be by management server be responsible for and the FCoE node between Beacon mutual, and the Probe flow process of FCoE node and Claim flow process can still adopt the conventional forms of broadcasting to send, like this other nodes are the Claim message that can receive the FCoE node, just can obtain the node identification that carries in the Claim message, set up link if desired and then record this node identification and get final product; Certainly, optionally, the Claim flow process of FCoE node also can only limit to and management server between carry out, be that the FCoE node adopts the clean culture form to send Claim message to management server, carry the node identification that it generates at random, by management server this node identification is informed other nodes by the node change notification message of broadcasting again.
Embodiment four
Fig. 5 is the workflow diagram of the FCoE node among the another embodiment of FCoE network linking management method of the present invention, and as shown in Figure 5, the execution flow process of FCoE node is as follows:
501, the FCoE node generates node identification at random;
Wherein, the FCoE node gets final product according to the scheme generation node identification of the VN2VN regulation of routine, is not described in detail in this.
502, whether the FCoE node detection exists management server;
Need to prove that this step is not necessarily carried out immediately after the FCoE node generates node identification at random, get final product so long as before the FCoE node sends Beacon, carry out.
In the present embodiment, provide two kinds of optional FCoE node detection whether to have the mode of management server:
A kind of mode is that the FCoE node can judge whether to receive the Beacon that management server sends, the sign of carrying described management server among the described Beacon; If receive, then show to have management server, otherwise, show not have management server;
Concrete, the FCoE node can be set a detection time, and judges in this default detection time whether to receive the Beacon that management server sends; The Beacon of management server periodically sends, so can for example can be set to 2 time spans about the cycle greater than the transmission cycle of management server Beacon the detection time that the FCoE node is set usually.In like manner, management server is when starting timer and detect the Beacon that the FCoE node periodically sends, and the transmission cycle that the Preset Time of described timer also is greater than FCoE Node B eacon is 2 cycles for example.
In the present embodiment, if the FCoE node does not receive the Beacon that management server sends in default detection time, then show not have management server, continue to carry out 503; Otherwise, carry out 504;
Another kind of mode is whether FCoE node active inquiry exists management server;
Concrete, increased a new FCoE node such as the FCoE network, this new FCoE node just can be to query messages of broadcasting in the FCoE network, and this query messages carries the sign of management server, is used for inquiry FCoE network and whether has management server.If management server is arranged, this management server will return a response message to the FCoE node, determines to exist management server when the FCoE node receives this response message, then continues to carry out 504; Otherwise, if the FCoE node does not receive response message, then determine not exist management server, continue to carry out 503.Optionally, the FCoE node is when waiting for the response message that the receiving management server returns, also can set a detection time, and judge in this default detection time whether can receive the response message that management server returns, rationally can receive response message as long as arrange this detection time.
503, the FCoE node is carried out the VN2VN flow process;
Wherein, if the FCoE node does not receive the Beacon that management server sends in default detection time, show that then this FCoE network is not have management server, then the flow process of just execution routine of FCoE node gets final product.
504, the sign of FCoE node record management server in the neighbor table of this locality;
Wherein, if the FCoE node receives the Beacon that management server sends in default detection time, then show in this FCoE network and have management server, the sign of FCoE node record management server in the neighbor table of this locality shows that the FCoE node also can communicate by letter with management server.
505, the FCoE node periodically sends Beacon to management server;
Wherein, described Beacon is used for notifying the local normal, chain of described management server to be connected on the FCoE network, management server then also can start timer, if in the Preset Time of timer, receive this Beacon, the link that then shows this FCoE node is normal, management server can upgrade timer, waits for the Beacon that receives next time, so periodically detects.
506, the FCoE node starts timer;
Wherein, the FCoE node is after the sign of record management server, just begin to carry out periodically sending Beacon to management server in 505, also begin periodically to detect the Beacon that management server sends simultaneously, to judge that management server is at the linking status of FCoE network.
The FCoE node need start timer; this timer is the time of reception for the judgement management server Beacon of subsequent step; usually can for example can be set at 2 time spans about the cycle greater than the transmission cycle of management server Beacon in the Preset Time that this timer is set.
507, the FCoE node judges whether the overtime Beacon that management server sends that do not receive;
Wherein, if the FCoE node receives the Beacon that described management server sends in the Preset Time that described timer is set, determine that then described management server is normal in the link of FCoE network; To return and carry out 506, namely restart timer, wait for the Beacon next time that the receiving management server sends.
If the FCoE node does not receive the Beacon that management server sends in the Preset Time that described timer is set, determine that then described management server disconnects in the link of FCoE network, continues to carry out 508.
508, the FCoE node is deleted the sign of described management server from the neighbor table of this locality;
Wherein, the FCoE node just can be deleted the sign of management server after determining that the link of management server at the FCoE network disconnects from its local neighbor table.
At this moment, the FCoE node can return carries out 502, surveys the management server that whether has other.
In the present embodiment, the FCoE node with described management server between link just often, when namely in 507, judging the Beacon that can in the Preset Time of timer, receive the management server transmission, the FCoE node also might receive the node change notification message that is used for notifying certain node link disconnection that management server sends, and namely carries out 509; Perhaps, the FCoE node might receive also that management server sends is used for the node change notification message of notifying certain node to increase newly, namely carries out 511.
509, FCoE node receiving management server is in the node change notification message of FCoE Web broadcast, and node identification and the link of carrying the FCoE node of break link disconnect sign;
Wherein, to be described management server periodically detecting the Beacon that the FCoE node sends to the node change notification message, and send when not receiving the Beacon that described FCoE node sends, the FCoE node here refers to the FCoE node of break link.When management server does not receive the Beacon that the FCoE node of described break link sends in the Preset Time of its timer, the link that will determine this FCoE node disconnects, and then can disconnect sign in node identification and the link of the FCoE node of the described break link of FCoE Web broadcast.
At this moment, the FCoE node will be inquired about the neighbor table of self, judges the node identification of the FCoE node whether this break link of storage is arranged in the neighbor table; If storage is arranged, the FCoE node also can continue to carry out 510; If not storage, the FCoE node can keep neighbor table constant.
510, the FCoE node is according to described node change notification message, and the node identification of the FCoE node of break link is deleted from the neighbor table of this locality.
511, FCoE node receiving management server carries the node identification and the link foundation sign that increase newly to the FCoE node of FCoE network in the node change notification message of FCoE Web broadcast;
Wherein, to be management server send when receiving the node identification that increases newly to the FCoE node of FCoE network first described node change notification message.If the FCoE node need be set up link with this FCoE node that increases newly, and not storage as yet in its neighbor table, then carry out 512;
512, the FCoE node is according to described node change notification message, and described increasing newly to the node identification of the FCoE node of FCoE network is added in the local neighbor table.
The FCoE network linking management method of the embodiment of the invention, by in the FCoE network, management server being set, each FCoE node only needs periodically to send Beacon to management server, and need not effectively save the network bandwidth to whole Web broadcast Beacon; Management server is responsible for the unified Beacon that receives all FCoE nodes in the network, detect the linking status of all FCoE nodes, and lose when link at certain node, notify other nodes in the network with this event broadcast, thereby alleviated the burden of FCoE node.
