Below with reference to Fig. 3 and Fig. 4, each step of the application is described in detail.
BMC needs in server are powered on and can be just managed to server process message, therefore can be carried out to BMC Electricity, so that BMC electrifying startup and bringing into operation.After BMC is powered on, server just can start to execute message forwarding on the whole Method.
When not powering on, server position in a link or structure may change, but this change server by It can not know in not powering on, therefore after powering on each time, server requires to redefine oneself position in a link, To determine how to forward the message of acquisition by determining position in a link.
In the present embodiment, after the power-up, server is promiscuous mode to the processing mode of message, i.e., server is to acquisition Any unicast or broadcast message can be carried out analysis processing.So by any unicast or broadcast message analysis to acquisition at Reason, server then can be by within a preset time, judging whether that the dedicated management mouth from server obtains forwarding device transmission Equipment notification packet determine the position of server in a link.
As a kind of mode optionally, the equipment notification packet that forwarding device is sent can be STP BPDUs (Spanning Tree Protocol, Spanning-Tree Protocol) and/or LLDP message (Link Layer Discovery Protocol, link layer hair Existing agreement).STP BPDUs can be the message generated and sent by the forwarding device, and if the device type of LLDP message expression For forwarding device, then the LLDP message can be the message generated and sent by the forwarding device.
For forwarding device, forwarding device, can be by certain continual generation of duration simultaneously according to preset rules Send the STP BPDUs and/or LLDP message, wherein certain duration can be 5-7 seconds.If therefore setting big for preset time In certain duration, for example, set preset time to 30 seconds, then after power-up, positioned at the clothes of the first end of link It is engaged in server and position of the server due to being connect with forwarding device, positioned at the first end of link of device and the second end positioned at link STP BPDUs and/or LLDP message can be then received in preset duration in the server of the second end of link.In this way, service Device passes through the STP BPDUs and/or LLDP for judging whether that equipment transmission is obtained from the dedicated management mouth of server within a preset time Message, and judge whether STP BPDUs and/or LLDP message that forwarding device transmission is obtained from the Sharing Management mouth of server, Server is assured that the first end for oneself being located at link, the second end of link or the first end and link that are located at link Second end between.
If server determines the Sharing Management from server within a preset time by analyzing the message of acquisition Mouth obtains STP BPDUs and/or obtains the LLDP message in message comprising device type for forwarding device, then server can To determine that server is located at the first end of link, that is, the first port of the Sharing Management mouth and forwarding device that determine server connects It connects.
If server determines not within a preset time by analyzing the message of acquisition from the shared of server Any management mouth in management mouth and dedicated management mouth obtains STP BPDUs and/or obtains in message is comprising device type The LLDP message of forwarding device, then server can determine server be located at link first end and link second end it Between, that is, determine that the Sharing Management mouth of server and dedicated management mouth are not connect with forwarding device.
If server determines the dedicated management from server within a preset time by analyzing the message of acquisition Mouth obtains STP BPDUs and/or obtains the LLDP message in message comprising device type for forwarding device, then server can To determine that server is located at the second end of link, that is, the second port of the dedicated management mouth and forwarding device that determine server connects It connects.
In the present embodiment, server can determine that the processing to message is advised by determining oneself position in a link Then, so that server after powering on to message mix tupe change by processing rule handle.
In the present embodiment, if the first port of Sharing Management mouth and forwarding device that server is determined as server connects, Or it is determined as the Sharing Management mouth of server and after dedicated management mouth do not connect with forwarding device, server is determined to report Text processing rule may include:
Server analyzes the message of acquisition, however, it is determined that is the unicast message for being sent to server, then server The unicast message can be performed corresponding processing, without being forwarded；If it is determined that be sent in other servers or network The unicast message of other equipment, then server can not then handle and forward the unicast message；If it is determined that for STP BPDUs and/ Or the broadcasting packet of LLDP message, then server can also perform corresponding processing the STP BPDUs and/or LLDP message, and Without forwarding；If it is determined that being other types of broadcasting packet, for example, if clothes are included in common ARP request and the request The IP address of oneself and MAC Address of business device, then arp response, which can be generated, in server carrys out the response ARP request；Alternatively, if For common ARP request and the request does not include the IP address of oneself and MAC Address of server, then server can forward The ARP request, if but the ARP request is special ARP request, server can handle the special ARP request, should with basis ARP request generates another corresponding ARP request, and another ARP request is connect together with ARP request to be forwarded from non- Receiving end mouth is sent.
In addition, the processing rule that server is determined can also include:
Server is before any kind of message of forwarding, it can be determined that whether the message needs from the dedicated of server Manage mouth forwarding.It, can be from corresponding ports other in addition to dedicated management mouth if not forwarded from the dedicated management mouth of server The message is forwarded, it, can be based on the Sharing Management mouth and forwarding device of server if being forwarded from the dedicated management mouth of server First port connection or the Sharing Management mouth based on server and dedicated management mouth do not connect with forwarding device, can should Message is forwarded from the dedicated management mouth of server.
It should be noted that first port connection or server due to the Sharing Management mouth and forwarding device of server Sharing Management mouth and dedicated management mouth are not connect with forwarding device, thus the dedicated management mouth of the server then can in link Adjacent next server connection.In this way, can be forwarded to from the message that the dedicated management mouth of server forwards Adjacent next server causes message storm in link without being forwarded to forwarding device.
In the present embodiment, if the second port of dedicated management mouth and forwarding device that server is determined as server connects, Server determines that the processing rule to message may include:
Server analyzes the message of acquisition, however, it is determined that is the unicast message for being sent to server, then server The unicast message can be performed corresponding processing, without being forwarded；If it is determined that be sent in other servers or network The unicast message of other equipment, then server can not then handle and forward the unicast message；If it is determined that for STP BPDUs and/ Or the broadcasting packet of LLDP message, then server can also perform corresponding processing the STP BPDUs and/or LLDP message, and Without forwarding；If it is determined that being other types of broadcasting packet, for example, ARP request, server can handle ARP request, with Another corresponding ARP request is generated according to the ARP request, and by another ARP request together with ARP request to be forwarded It is sent from non-reception port.
In addition, the processing rule that server is determined can also include:
Server is before any kind of message of forwarding, it can be determined that whether the message needs from the dedicated of server Manage mouth forwarding.If it is not, then the message can be forwarded from corresponding port, if so, can be based on the dedicated management of server Mouth is connect with the second port of forwarding device, can be by the packet loss without forwarding.
It should be noted that since the dedicated management mouth of server and the second port of forwarding device connect, if from service The dedicated management mouth of device E-Packets, which may be forwarded to forwarding device and cause message wind in link Cruelly.
It is powering on and is determining oneself position in a link, and determining after handling rule accordingly, server is just The message of acquisition can be handled according to the processing rule determined, i.e., server can execute step S110.
Step S110: the server by the Sharing Management mouth obtain that the adjacent upper equipment sends to It E-Packets.
It is that message to be forwarded can be forwarded in link by first port based on forwarding device default conditions, takes in this way The Sharing Management mouth of business device can obtain adjacent upper one by connecting with an adjacent upper equipment by Sharing Management mouth The message to be forwarded that a equipment is sent.Position based on server in a link, if server determines that server is located at link First end, then an adjacent upper equipment can be forwarding device, and server can obtain forwarding by Sharing Management mouth and set The message to be forwarded that standby first port is sent；And if server determines the second end for being located at link or is located at first end and second Between end, then an adjacent upper equipment can be other servers, then server can be obtained by Sharing Management mouth Obtain the message to be forwarded that the dedicated management mouth of an adjacent upper server is sent.
Step S120: the message to be forwarded is forwarded to described adjacent by the server by the dedicated management mouth Next equipment.
After server obtains the message to be forwarded, server can be based on processing rule come to the message to be forwarded Reason.
Optionally, if server determines server and is located at first end or between first end and second end, server First end or the processing rule determined between first end and second end can be located at based on server to determine this Message to be forwarded is handled, to judge whether to need to forward by the dedicated management mouth of server.If it is determined that the report to be forwarded Text can be forwarded by the non-dedicated management mouth of server, then server can be somebody's turn to do by corresponding non-dedicated management mouth forwarding Message to be forwarded.And if it is determined that the message to be forwarded can be forwarded by the dedicated management mouth of server, then server can also The message to be forwarded is forwarded to adjacent next equipment by the dedicated management mouth of server to determine with processing rule, i.e., It is forwarded to the Sharing Management mouth of adjacent next server.
If server determines that server is located at second end, server can be located at second end based on server and determine Rule is handled to determine that the message to be forwarded is handled, to judge whether to need to forward by the dedicated management mouth of server. If it is determined that the message to be forwarded can be forwarded by the non-dedicated management mouth of server, then server can be by corresponding non- Dedicated management mouth forwards the message to be forwarded.And if it is determined that the message to be forwarded can be turned by the dedicated management mouth of server Hair, then server can handle rule also to determine and not forward the packet loss to be forwarded.
It is assumed that the dedicated management mouth A2 of server A and the Sharing Management mouth B1 connection of server B, the dedicated pipe of server B Reason mouth B2 is connect with the Sharing Management mouth C1 of server C, the Sharing Management mouth of the dedicated management mouth C2 and server D of server C The port E1 of D1 connection, the Sharing Management mouth A1 and interchanger E of server A is connect, the dedicated management mouth D2 of server D with exchange The port E2 connection of machine E.
After the power-up, server A obtains the STP BPDUs and/or LLDP message that interchanger E is sent by Sharing Management mouth A1 And it determines Sharing Management mouth A1 and is connect with interchanger E.Server D obtains the STP report that interchanger E is sent by dedicated management mouth D2 Text and/or LLDP message and determine dedicated management mouth D2 and connect with interchanger E.And server B and server C are then due to default STP BPDUs and/or LLDP message are not obtained in duration and determines and is not connect with interchanger E.
After obtaining message, server A can will be needed from the message that dedicated management mouth A2 is forwarded from dedicated management mouth A2 It is forwarded to the Sharing Management mouth B1 of server B；Server B can will be needed from the message that dedicated management mouth B2 is forwarded from dedicated pipe Reason mouth B2 is forwarded to the Sharing Management mouth C1 of server C；Server C can will need from the message that dedicated management mouth C2 is forwarded from Dedicated management mouth C2 is forwarded to the Sharing Management mouth D1 of server D；What server D can forward needs from dedicated management mouth D2 Packet loss does not forward.
It is understood that server can be right based on the above-mentioned processing rule determined in the case where forming link The message of acquisition is correctly handled.
In the present embodiment, if the link in link at a certain Sharing Management mouth disconnects, then connecting with the Sharing Management mouth The link of dedicated management mouth of server also disconnect, and link is made to be divided into two the first sublinks and the second subchain Road.The first port of the server to the forwarding device that disconnect from the dedicated management mouth is then the first sublink.Due to dedicated management The disconnection of mouth has no effect on each server in the first sublink and handles message, i.e. each service in the first sublink Device normally can be handled or be abandoned to the message of acquisition, therefore each server in the first sublink can continue base It continues to run, and can not be performed corresponding processing for the dedicated management mouth disconnected in the processing rule currently to message.
But for the second sublink at the server to the second port of forwarding device that Sharing Management mouth disconnects, altogether It enjoys management mouth and disconnects the message that the server meaned in second sublink can not obtain the first port forwarding of forwarding device, It also can not just be worked normally where the server disconnected to Sharing Management mouth.Therefore, the service in second sublink Device can perform corresponding processing, so that forwarding device carries out ARP entry study to the server in second sublink, in turn So that second sublink also can normally carry out message forwarding.
It is illustrated below in conjunction with Fig. 5, when the link at a certain Sharing Management mouth disconnects in a link, is set to forwarding How server in second sublink of standby second port connection, which carries out relevant treatment, is described in detail, Yi Jiye It is described in detail to how about forwarding device carries out ARP entry study to the server in second sublink.
As a kind of mode that the link at the Sharing Management mouth of the server disconnects, which is able to detect that certainly Link at own Sharing Management mouth disconnects, that is, detects that the state of oneself Sharing Management mouth is Down.In this case, server A special ARP request can be generated according to preset rules.
Optionally, the special ARP request that server generates can be the first ARP request, in first ARP request Source address can be the MAC Address of the management mouth of the server, and the destination address in first ARP request is special first wide Broadcast address, for example, 127.0.0.1.
In addition, server is based on the link detected at oneself Sharing Management mouth while generating first ARP request Disconnect, then server can also the processing rule to message be adjusted, i.e., will " the dedicated management mouth for determining server not Connecting with forwarding device will just need to forward from the message that the dedicated management mouth of server forwards from the dedicated management mouth of server, Connecting in the dedicated management mouth for determining server with forwarding device then will can need to forward from the dedicated management mouth of server Packet loss " adjustment are as follows: " no matter whether the dedicated management mouth of server connect with forwarding device, server can be passed through Dedicated management mouth sends and receivees message ".
Furthermore after server generates the first ARP request, server is by the dedicated management mouth of server by the first ARP Request is sent to adjacent next equipment.
If the second sublink illustrates that adjacent next equipment can be service there are also the server in addition to the server Device, the 2nd ARP which then can generate the MAC Address comprising itself based on the first ARP request are asked It asks, and forwards the first ARP request and the second ARP request downwards.Each service in such second sublink in addition to the server Device can execute the next server identical operation adjacent with this.Then in second sublink each of in addition to the server The Sharing Management mouth of server can obtain first ARP request, and the dedicated management mouth of each server can should First ARP request forwards.And second each server in sublink in addition to the server based on acquisition this first The second ARP request of each of the MAC Address of management mouth comprising each server that ARP request can be generated, each server Dedicated management mouth the second ARP request of each of generation can also be sent.In this way, the Sharing Management mouth of each server Obtain the second ARP request that other each servers are sent, then by the dedicated management mouth of each server by other each clothes The second ARP request that business device is sent forwards.Thus, each server successively forwards the second port so that forwarding device Obtain the second ARP request that first ARP request and each server generate.Certainly, each clothes of first ARP request are obtained The processing rule adjustment of message is also the processing of the server disconnected with the Sharing Management mouth based on first ARP request by business device Rule is identical.
If the not no server in addition to the server in the second sublink, illustrates that adjacent next equipment can be service Device, then the second port of forwarding device can obtain first ARP request of server transmission.
It is other as a kind of mode that the link at the Sharing Management mouth of other servers before the server disconnects Server can generate and send the first ARP request of the MAC Address of the management mouth comprising other servers, and adjust this its Processing rule of its server to message.Correspondingly, the Sharing Management mouth for the server being located in second sublink can To obtain first ARP request to the forwarding of the acquisition first ARP request by each server before the server, Alternatively, the dedicated management mouth for other servers that the Sharing Management mouth of the server and the Sharing Management mouth disconnect connect this First ARP request that other servers that Sharing Management mouth disconnects are sent.
For server based on the first broadcast address special in the first ARP request, server can know other servers Sharing Management mouth disconnect and server can also be known the processing rule to message is needed to be adjusted.Therefore server It can be by " not connecting with forwarding device in the dedicated management mouth for determining server will just need to turn from the dedicated management mouth of server The message of hair is forwarded from the dedicated management mouth of server, and connecting in the dedicated management mouth for determining server with forwarding device then can be with By the packet loss that needs are forwarded from the dedicated management mouth of server " it is adjusted to the other servers disconnected with the Sharing Management mouth It is identical: " no matter whether the dedicated management mouth of server connect with forwarding device, the dedicated management mouth of server can be passed through Send and receive message ".
Furthermore server is based on first ARP request, it can also obtain and need to generate second comprising own MAC address ARP request, therefore the MAC Address of the management mouth of servers other in the first ARP request can be replaced with the server by server Management mouth MAC Address, thus obtain the second ARP request.Server can be by the first ARP request and the 2nd ARP generated Request is sent to adjacent next equipment by the dedicated management mouth of server.
If illustrating that adjacent next equipment can be with there are also other servers below the server in the second sublink It is server, which, which obtains, then can generate the MAC Address comprising itself based on the first ARP request Second ARP request, and the second ARP request for forwarding the first ARP request, other servers to send downwards and oneself generate second ARP request.Each server in such second sublink in addition to the server can execute the next service adjacent with this The identical operation of device, the second port for allowing for forwarding device obtain first ARP request and each server generate second ARP request.
If illustrating that adjacent next equipment can be with without others servers below the server in the second sublink Forwarding device, thus the second port of forwarding device can obtain that first ARP request and each server generate the Two ARP requests.
Forwarding device is carried out based on the second ARP request that the first ARP request of acquisition and/or each server generate ARP entry study, then be assured that can be by second port come to the server of the second end of link for forwarding device Dedicated management mouth sends message.And since each server in the second sublink is after adjusting the processing rule to message, often A server can handle the message of acquisition or each server is obtained by the dedicated management mouth of each server What is obtained is forwarded to message to be forwarded in the Sharing Management mouth of adjacent server, turns to realize message to be forwarded in the second subchain The processing and forwarding of road, and then the server realized in the case where link disconnects, in the second sublink also can continue to It is worked normally.
Continue aforementioned it is assumed that if being disconnected at the Sharing Management mouth C1 of server C, then link is divided into including server The first sublink of A and server B, and the second sublink including server C and server D.Wherein, in the first sublink Server A and server B do not adjust, continue to handle message based on original processing is regular.
For the second sublink, server C it is adjustable itself to the processing of message rule, and by the first ARP of generation Request is sent to server D by the dedicated management mouth C2 of server C.The Sharing Management mouth D1 of server D can obtain this One ARP request, to be advised itself with the processing of server C to the processing rule adjustment of message according to first ARP request It is then identical.Simultaneously, server D can generate the second ARP request based on first ARP request, and by the first ARP request and The dedicated management mouth D2 that second ARP request passes through server D is sent to interchanger E.In this way, interchanger E can be based on first ARP request and the second ARP request carry out ARP entry study and know that second sublink also can handle message, and then interchanger E It can then determine while message is sent to the first sublink by port E1, message can also be sent to by port E2 Second sublink.In this way, the dedicated management mouth D2 of server D is obtained with the message that interchanger E is sent by port E2.If The message is destined to server D oneself, then server D can be handled the message；If but the message is destined to Server C, then server D can forward the packet to server C by the Sharing Management mouth D1 of server D.
In the present embodiment, if the link in link at a certain Sharing Management mouth reverts to connection from disconnection, then total with this The link for enjoying the dedicated management mouth of the server of management mouth connection also reverts to connection from disconnection, and makes the first sublink and second Sublink is again coupled to constitute the complete link.
For the first sublink, the recovery connection of dedicated management mouth means in first sublink no longer with independent Sublink exist.Therefore, the server in first sublink can perform corresponding processing so that forwarding device to this Server in one sublink carries out ARP entry study and knows first sublink and revert to complete link from disconnection.
For the second sublink, the recovery connection of Sharing Management mouth means in second sublink not also again with list Only sublink exists.Therefore, the server in second sublink can perform corresponding processing, so that forwarding device is deleted The ARP entry that the server in second sublink carries out is learnt before, so that second sublink is no longer individual Carry out message forwarding.
It is illustrated below in conjunction with Fig. 4 and Fig. 5, the link at a certain Sharing Management mouth restores from disconnection in a link For connection when, the server in second sublink that the second port with forwarding device is connect how to carry out relevant treatment into Row explains in detail, and also how about deletes forwarding device the ARP entry of the server in second sublink of study It is described in detail.
A kind of mode of connection, the server are reverted to from disconnection as the link at the Sharing Management mouth of the server It is able to detect that the link at oneself Sharing Management mouth reverts to connection from disconnection, that is, detects the state of oneself Sharing Management mouth Up is reverted to from Down.In this case, server can regenerate a special ARP request according to preset rules.
Optionally, the special ARP request that server generates can be third ARP request, in the third ARP request Source address can be the MAC Address of the management mouth of the server, and the destination address in the third ARP request is special second wide Broadcast address, for example, 127.0.0.2.And server, which can also generate source address, to be the MAC of the management mouth of the server Address and destination address are the 4th ARP request of conventional broadcast address.
In addition, server is based on the link detected at oneself Sharing Management mouth while generating the third ARP request Revert to connection from disconnection, then server can also the processing rule to message be adjusted again, i.e., will be " no matter server Dedicated management mouth whether connect with forwarding device, message can be sended and received by the dedicated management mouth of server " it is extensive It is multiple initial: " not connect the just dedicated management by needs from server with forwarding device in the dedicated management mouth for determining server The message of mouth forwarding is forwarded from the dedicated management mouth of server, is connect then in the dedicated management mouth for determining server with forwarding device The packet loss that needs can be forwarded from the dedicated management mouth of server ".
Furthermore after server generates third ARP request, server is by the dedicated management mouth of server by the 3rd ARP Request is sent to adjacent next equipment.And server can also generate comprising server management mouth MAC Address and Destination address is the 4th ARP request of conventional broadcast address, and the Sharing Management mouth of the server can also be by the generation 4th ARP request is sent to a upper equipment adjacent in the first sublink.
For third ARP request, if server determines that connecting with the dedicated management mouth of server is forwarding device, i.e. phase Adjacent next equipment is forwarding device, is not forwarded then server can abandon the third ARP request.
Also for third ARP request, if server determines that connecting with the dedicated management mouth of server is server, i.e. phase Adjacent next equipment is server, then server third ARP request can be sent to by dedicated management mouth it is adjacent Next server generates adjacent next server comprising own MAC address based on the third ARP request 4th ARP request, and whether connect forwarding device downwards based on judgement and determine whether to forward the third ARP request downwards.This Sample, which is obtained with the 4th ARP request that adjacent next server generates and sends, then server can Pass through Sharing Management with the 4th ARP request that the 4th ARP request for generating itself and adjacent next server are sent Mouth is transmitted to an adjacent upper equipment.
Each server in such second sublink in addition to the server can execute the next service adjacent with this The identical operation of device.The Sharing Management mouth of each server so in second sublink in addition to the server can obtain The third ARP request, and the dedicated management mouth of each server can forward the third ARP request to next one Adjacent server or each server are connect with forwarding device based on the dedicated management mouth of each server and can also be incited somebody to action Third ARP request discarding does not forward, thus the successively forwarding of each server so that each server can obtain this Three ARP requests.At the same time, each server of the third ARP request is obtained also based on the third ARP request by the place of message It is identical from the processing rule of server for disconnecting recovery connection as the Sharing Management mouth for managing rule adjustment.
In addition, each server in the second sublink in addition to the server is based on executing the next service adjacent with this The identical operation of device.Each server in second sublink in addition to the server may be used also based on the third ARP request of acquisition It is each of conventional broadcast address the 4th with the MAC Address and destination address of the management mouth comprising each server of generation The Sharing Management mouth of ARP request, each server can also send the 4th ARP request of each of generation to adjacent upper one The dedicated management mouth of server.It is sent in this way, the dedicated management mouth of each server of chain road obtains other each servers The 4th ARP request, then the 4th ARP request that other each servers are sent is turned by the Sharing Management mouth of each server It sends out, so that each server transfers the 4th ARP request of acquisition from the Sharing Management mouth of each server in link It goes, so that the first port of forwarding device obtains the 4th ARP request that each server generates.
In this way, the first port of forwarding device, which is obtained with the 4th ARP request that each server generates, obtains second The MAC Address of the management mouth of each server in sublink, then forwarding device can be based on each service in the second sublink The MAC Address of the management mouth of device carries out ARP entry study, thus by the MAC address learning of the management mouth of each server to the On Single port, thus forwarding device can no longer by second end from second port to link server dedicated management mouth Message is sent, and server of the first port into link can be continued through and E-Packeted.
Continue aforementioned it is assumed that if reverting to connection from disconnection at the Sharing Management mouth C1 of server C, then the first sublink Complete link is then merged into again with the second sublink.
For the second sublink, the third ARP request of generation can be passed through the dedicated management mouth of server C by server C C2 is sent to server D and server C and can send out the 4th ARP request of generation by the Sharing Management mouth C1 of server C Give server B.The Sharing Management mouth D1 of server D can obtain the third ARP request, and server D can be based on the third ARP request generates the 4th ARP request.The port E2 of the dedicated management mouth D2 and interchanger E of server D are connect, therefore server D can Will generate the discarding of the 4th ARP request, and the Sharing Management mouth D1 of the 4th ARP request server D is also sent to by server D Server C.In this way, by the Sharing Management mouth C1 of server C by the server B that is forwarded to of the 4th ARP request of server D Dedicated management mouth B2, and by the Sharing Management mouth B1 of server B by the of the 4th ARP request of server D and server C The dedicated management mouth A2 for being forwarded to server A of four ARP requests, then will be serviced by the Sharing Management mouth A1 of server A again The port E1 for being forwarded to interchanger E of 4th ARP request of the 4th ARP request and server C of device D.Interchanger E can be serviced The 4th ARP request of device D and the 4th ARP request of server C carry out ARP entry study, and then interchanger E is by server D's On the MAC address learning of MAC Address and server C to port E1, so as to which the message for needing to forward is sent out by port E1 Give link.
Connection is reverted to from disconnection as the link at the Sharing Management mouth of other servers before the server A kind of mode, the 3rd ARP that other servers can generate and send the MAC Address of the management mouth comprising other servers are asked It asks, and adjusts other servers to the processing rule of message.Correspondingly, the server being located in second sublink is total to The forwarding of the acquisition third ARP request can be somebody's turn to do by each server before the server by enjoying management mouth Third ARP request, alternatively, the dedicated management for other servers that the Sharing Management mouth of the server and the Sharing Management mouth disconnect Connection obtains the third ARP request that the Sharing Management mouth is sent from the other servers for disconnecting recovery connection.
For server based on the second broadcast address special in third ARP request, server can know other servers Sharing Management mouth revert to connection and server from disconnection and can also know the processing rule to message is needed to adjust It is whole.Therefore server " no matter whether the dedicated management mouth of server connect with forwarding device, can also will can pass through server Dedicated management mouth send and receive message " revert to it is initial: " the dedicated management mouth for determining server not with forwarding device Connection will just need to forward from the message that the dedicated management mouth of server forwards from the dedicated management mouth of server, service determining The dedicated management mouth of device connect the packet loss that can then forward needs from the dedicated management mouth of server with forwarding device ".
Furthermore server is based on the third ARP request, it can also obtain and need to generate the 4th comprising own MAC address ARP request, therefore the MAC Address of the management mouth of servers other in third ARP request can be replaced with the server by server Management mouth MAC Address, to obtain the 4th ARP request, such server can pass through the Sharing Management mouth of server 4th ARP request is sent to an adjacent upper equipment.
If it is forwarding device that server, which is determined and connect with the dedicated management mouth of server, i.e., adjacent next equipment is Forwarding device does not forward then server can also abandon the third ARP request.
If it is server that server, which is determined and connect with the dedicated management mouth of server, i.e., adjacent next equipment is clothes Business device, then third ARP request can be sent to adjacent next server by dedicated management mouth by server.
