Such scheme comprises two kinds of application scenarioss, and a kind of scene is legacy network, and namely in network, inter-exchange can run Routing Protocol; Scene is the network controlled by control appliance completely, and the equipment in network does not run any Routing Protocol, relies on stream table to carry out message repeating.Further illustrate below by the embodiment of the present invention one and two, the present invention by calculating active-standby path, and carries out fast detecting, when fault being detected to fault on the path of traffic forwarding, in time by flow switch on standby path, thus ensure that VXLAN business can quick-recovery soon.
Embodiment one
For the VXLAN network running Routing Protocol, its schematic network structure as shown in Figure 3, hangs user 2 under hanging user the 1, two VTEP in Fig. 3 under a VTEP.Because VTEP in the present embodiment and switch all do not have control appliance to control, so respectively configure below, it is all the mode static configuration by order line.VXLAN tunnel between a VTEP and the 2nd VTEP also comprises multiple intermediate equipments such as switch 1 to switch N.
Message forwarding method in embodiment one VXLAN network comprises the following steps:
Step 31, a VTEP configure the VXLAN tunnel between a VTEP and the 2nd VTEP.
The first preferred path between step 32, a VTEP calculating described VTEP and the 2nd VTEP and the second preferred path.
Step 33, a VTEP associate in the down hop of described first preferred path with the VTEP on the second preferred path with described VXLAN tunnel with outgoing interface, form the active-standby path list item with described VXLAN tunnel-associated, in the active-standby path list item of described and described VXLAN tunnel-associated, the first preferred path is state of activation, second preferred path is unactivated state, forwards on described first preferred path to make message.
It should be noted that, with the active-standby path list item of VXLAN tunnel-associated, main path is in state of activation, and standby path is in unactivated state, and like this, message will forward at the main path being in state of activation.
Step 34, the VXLAN tunnel of a VTEP between a VTEP and the 2nd VTEP are set up two-way converting and detect BFD session; If a VTEP does not receive the BFD fault detect message that the 2nd VTEP sends in the given time, then determine this BFD fault detect message the first preferred path fault of process.
Particularly, the present invention, for realizing fault fast detecting, the tunnel between a VTEP and the 2nd VTEP is set up two-way converting and detects (Bidirectional Forwarding Detection, BFD) session.It should be noted that, BFD is used for the communication failure between detection two equipment.A pair equipment every bar passage between which periodically sends BFD message, if certain equipment does not receive BFD message within the sufficiently long time, then thinks and to be out of order in certain part of this duplex channel to opposite equip..In the embodiment of the present invention for fault detect message for BFD message is illustrated, in a particular application, fault detect message is not limited to BFD message, as long as the message that can realize fault detect is all in protection scope of the present invention.
Step 35, a VTEP upgrade described with the first preferred path in the active-standby path list item of described VXLAN tunnel-associated with the state of activation of the second preferred path, first preferred path is updated to unactivated state, second preferred path is updated to state of activation, forwards on described second preferred path to make message.
Further, after step 35, one VTEP calculates the 3rd preferred path between a VTEP and the 2nd VTEP, by the down hop of the VTEP on described 3rd preferred path and outgoing interface and described VXLAN tunnel-associated, the down hop of the VTEP on described first preferred path is gone to associate with described VXLAN tunnel with outgoing interface, and using described second preferred path as main path, using described 3rd preferred path as standby path, namely active-standby path list item that is described and described VXLAN tunnel-associated is upgraded, second preferred path in the active-standby path list item of described and described VXLAN tunnel-associated is set to state of activation, 3rd preferred path is set to unactivated state, forward on described second preferred path to make message.
Preferably, according to Routing Protocol, a VTEP determines whether the first preferred path recovers, and when receiving the advertising of route message of the first preferred path recovery, the method comprises further:
One VTEP is by the down hop of the VTEP on described first preferred path and outgoing interface and described VXLAN tunnel-associated, the down hop of the VTEP on described 3rd preferred path is gone to associate with described VXLAN tunnel with outgoing interface, and using described first preferred path as main path, using described second preferred path as standby path, namely active-standby path list item that is described and tunnel-associated is upgraded, first preferred path in the active-standby path list item of described and described VXLAN tunnel-associated is set to state of activation, second preferred path is set to unactivated state, forward on described first preferred path to make message.
Enumerate concrete scene to be below described in detail.
One VTEP (VTEP1) creates VXLAN Tunnel, configures source IP address: VTEP1, object IP address: VTEP2 in VXLAN Tunnel;
VTEP1 calculates the path of VTEP2 according to Routing Protocol, if be found to VTEP2 to only have a paths, explanation cannot carry out path switching, can only carry out message repeating, so end process on this paths.
If VTEP1 is found to VTEP2 at least two paths, then find out the first preferred path and the second preferred path respectively as active-standby path, associate at the first preferred path with VXLAN Tunnel with outgoing interface with the down hop of the VTEP1 on the second preferred path, form the main path list item 1 and standby path list item 2 that associate with VXLAN Tunnel:, as shown in table 1
| List item | Tunnel Identifier | Outgoing interface | Down hop | State |
| List item 1 | VXLAN?Tunnel | Outgoing interface 1 | Down hop 1 | First preferred path state of activation |
| List item 2 | VXLAN?Tunnel | Outgoing interface 2 | Down hop 2 | Second preferred path unactivated state |
Table 1
Above-mentioned list item 1 and 2 is issued to forwarding chip by VTEP1, forwards on main path to make message.
After above-mentioned list item 1 and 2 is issued to forwarding chip by VTEP1, tunnel between VTEP1 and VTEP2 is set up BFD session, the i.e. enable BFD agreement in VTEP1 and VTEP2 both sides, consult the cycle sending BFD message, VTEP1 receives the BFD message that VTEP2 regularly sends, because above-mentioned list item 1 and 2 is issued to forwarding chip by VTEP1, so BFD message can forward on main path, when on main path, certain link or website break down, VTEP1 would not receive the BFD message that VTEP2 sends in the given time, therefore VTEP1 can perceive main path fault very soon, list item 1 and 2 is upgraded, as shown in table 2:
| List item | Tunnel Identifier | Outgoing interface | Down hop | State |
| List item 1 | VXLAN?Tunnel | Outgoing interface 1 | Down hop 1 | First preferred path unactivated state |
| List item 2 | VXLAN?Tunnel | Outgoing interface 2 | Down hop 2 | Second preferred path state of activation |
Table 2
List item 1 after above-mentioned renewal and list item 2 are issued to forwarding chip by VTEP1, and notice forwarding chip carries out the switching of active-standby path, forwards on the second preferred path to make message.
Because above-mentioned list item 1 and list item 2 are issued to forwarding chip by VTEP1, be namely switched on standby path, so BFD message can forward on standby path, namely by BFD packet check current standby path, i.e. the second preferred path.
Due to main path fault, flow has been switched on the second preferred path, at this moment needs to calculate the path made new advances, and as the standby path of the second preferred path, is implemented as:
VTEP1 calculates the 3rd preferred path of VTEP2 according to Routing Protocol, the down hop of the VTEP1 on the 3rd preferred path is associated with VXLAN Tunnel with outgoing interface, the down hop of the VTEP1 on the first preferred path is carried out associating with VXLAN Tunnel with outgoing interface, and list item 1 renewal is replaced with list item 3, as shown in table 3:
| List item | Tunnel Identifier | Outgoing interface | Down hop | State |
| List item 2 | VXLAN?Tunnel | Outgoing interface 2 | Down hop 2 | Second preferred path state of activation |
| List item 3 | VXLAN?Tunnel | Outgoing interface 3 | Down hop 3 | 3rd preferred path unactivated state |
Table 3
Original list item 1 is deleted from forwarding chip by VTEP1, above-mentioned list item 3 is issued to forwarding chip, like this, when on second preferred path, certain link or website break down, BFD can fast detecting out, can again occur path switch, therefore BFD message can forward on the standby path that the 3rd preferred path this article is new, namely by BFD packet check current standby path, i.e. the 3rd preferred path.
In a word, the solution of the present invention, after active-standby path switches, recalculates new standby path, to guarantee that subsequent packet does not interrupt.
Likely recover after first preferred path fault, after this path is recovered, advertising of route can be carried out to VTEP1, after VTEP1 receives the advertising of route on this path, the down hop of the VTEP1 on the first preferred path is associated with VXLAN Tunnel with outgoing interface, the down hop of the VTEP1 on the 3rd preferred path is carried out associating with VXLAN Tunnel with outgoing interface, and list item 2 and list item 3 renewal are replaced with list item 1 and list item 2, as shown in table 1.
Above-mentioned list item 1 and list item 2 are issued to forwarding chip by VTEP1, and notice forwarding chip carries out path smooth switching, forwards on the first preferred path to make message.Meanwhile, because above-mentioned list item 1 is issued to forwarding chip by VTEP1, be namely switched on the first preferred path, BFD message also can forward on the first preferred path, namely by the current main path of BFD packet check, i.e. the first preferred path.
So far, the present embodiment, for running the network of Routing Protocol, is VXLAN tunnel creation active-standby path, when VXLAN network failure, can Timeliness coverage, and fast service traffics are switched fast, decrease service outage duration.
Embodiment two
Control for by control appliance, stream table instructs the VXLAN network forwarded, and as shown in Figure 4, in Fig. 4, under a VTEP, user is VM1 to its schematic network structure, and under the 2nd VTEP, user is VM2.One VTEP and the 2nd VTEP, and multiple intermediate equipment such as switch 1 to switch N is all controlled by control appliance, these equipment are vSwitch or physical switches, do not run Routing Protocol, need control appliance to issue stream table and instruct message repeating.
Message forwarding method in embodiment two VXLAN network comprises the following steps:
Step 41, control appliance configure the VXLAN tunnel between the first tunnel terminal VTEP and the 2nd VTEP.
The first preferred path between step 42, a control appliance calculating described VTEP and the 2nd VTEP and the second preferred path.
Step 43, control appliance associate in the down hop of described first preferred path with the VTEP on the second preferred path with described VXLAN tunnel with outgoing interface; The stream table of the correspondence of stream table corresponding to the first preferred path and the second preferred path is issued to a VTEP, the stream table that described first preferred path is corresponding is identical with the occurrence of the stream table of the correspondence of the second preferred path, and the priority of stream table corresponding to described first preferred path is higher than the priority of stream table corresponding to the second preferred path, E-Packets on described first preferred path with the stream table making a VTEP corresponding according to described first preferred path.
Step 44, control appliance issue coupling BFD fault detect message to a VTEP, and outgoing interface is the stream table of described VXLAN tunnel interface, control appliance issues BFD fault detect message to a VTEP, sends BFD fault detect message to make a VTEP to the 2nd VTEP; If control appliance does not receive the BFD fault detect message that the 2nd VTEP send in the given time, then determine this BFD fault detect message the first preferred path fault of process.
Step 45, control appliance send amendment stream table to a VTEP, described amendment stream table, for informing that the priority of the stream table that described VTEP first preferred path is corresponding has been revised as the priority lower than stream table corresponding to the second preferred path, E-Packets on described second preferred path with the stream table making a VTEP corresponding according to described second preferred path.
Further, after step 45, control appliance calculates the 3rd preferred path between a VTEP and the 2nd VTEP, by the down hop of the VTEP on described 3rd preferred path and outgoing interface and described VXLAN tunnel-associated, the down hop of the VTEP on described first preferred path is gone to associate with described VXLAN tunnel with outgoing interface, and using described 3rd preferred path as standby path, using described second preferred path as main path, namely stream table corresponding to the 3rd preferred path is issued to a VTEP, the stream table that stream table covering first preferred path that described 3rd preferred path is corresponding is corresponding, the stream table that described 3rd preferred path is corresponding is identical with the occurrence of the stream table of the correspondence of the second preferred path, and the priority of stream table corresponding to the 3rd preferred path is lower than the priority of stream table corresponding to the second preferred path, E-Packet on described second preferred path with the stream table making a VTEP corresponding according to described second preferred path.
Preferably, control appliance finds message LLDP collection network topology information according to each equipment controlled by it to its link layer sent, and determine whether the first preferred path recovers, after the first preferred path recovers, the method comprises further:
Control appliance is by the down hop of the VTEP on described first preferred path and outgoing interface and described VXLAN tunnel-associated, the down hop of the VTEP on described 3rd preferred path is gone to associate with described VXLAN tunnel with outgoing interface, and using described first preferred path as main path, using described second preferred path as standby path, namely stream table corresponding to the first preferred path is issued to a VTEP, the stream table that stream table covering the 3rd preferred path that described first preferred path is corresponding is corresponding, the stream table that described first preferred path is corresponding is identical with the occurrence of the stream table of the correspondence of the second preferred path, and the priority of stream table corresponding to the first preferred path is higher than the priority of stream table corresponding to the second preferred path, E-Packet on described first preferred path with the stream table making a VTEP corresponding according to described first preferred path.
Enumerate concrete scene to be below described in detail.
Because the network in the present embodiment is controlled by control appliance, so set up tunnel again when needing communicating between users.Suppose to need same communication between the current VM1 of having and VM2 two users, direct-connected 2nd VTEP (VTEP2) of VM1 direct-connected a VTEP (VTEP1), VM2.After control appliance and all OVS equipment (OVS equipment comprises VTEP) connect, all OVS can send link layer to find message (LLDP) on control appliance, make control appliance find the topology of whole supervising the network.
It is the message of the IP address of VM2 that VTEP1 receives the object IP address (1.1.1.1) that VM1 sends, find the stream table not having to mate, therefore by message up sending control appliance, control appliance is according to the object IP address of message, the OVS finding VM2 direct-connected is VTEP2, therefore control appliance is determined to set up VXLAN tunnel between VTEP1 and opposite end VTEP2, and the VXLAN tunnel being configured in the foundation between VTEP1 and VTEP2 is VXLAN Tunne1.
Control appliance calculates the path from VTEP1 to VTEP2 according to the network topology of collecting, if be found to VTEP2 to only have a paths, explanation cannot carry out path switching, so issue a stream table directly to VTEP1 to point to this path, ends process.
If control appliance finds there are at least two paths from VTEP1 to VTEP2, then find out the first preferred path and the second preferred path respectively as active-standby path, associate at the first preferred path with VXLAN Tunne1 with outgoing interface with the down hop of the VTEP1 on the second preferred path, two stream tables are issued, as shown in stream table 1 and stream table 2 to VTEP1:
Stream table 1
Stream table 2
When message mates the stream table of high priority at VTEP1, in the process selecting main path to forward, due to the intermediate equipment between VTEP1 and VTEP2 also not running Routing Protocol, so when the intermediate equipment on main path receives message, this intermediate equipment finds the stream table not having to mate, and by message up sending control appliance, control appliance is according to the object IP address of message, issue stream table, be forwarded on VTEP2 to enable flow.In like manner, when subsequent packet selects standby path to forward, also need, by message activation control apparatus, stream table is handed down to corresponding intermediate equipment on path, thus realize forwarding.On path to be handed down to the stream table of each intermediate equipment not identical, have each self-corresponding outgoing interface and down hop.
Next, when message arrives VTEP2, also by message up sending control appliance is carried out activation control apparatus, stream table is handed down to VTEP2, the stream table 3 that control appliance issues to VTEP2 is two-stage stream table, as flowed shown in table 3, IP:VTEP2 for the purpose of first order stream table occurrence, action item is for separating VXLAN encapsulation; IP:VM2 for the purpose of the stream table occurrence of the second level, action item is for be forwarded to user VM2 at corresponding outbound port.
Stream table 3
Like this, the stream table that message can mate high priority at VTEP1 is forwarded to VM2 on main path.
After stream table issues, the present invention is for realizing fault fast detecting, and control appliance issues to VTEP1 and allows BFD message to pass through, to carry out the stream table of fault detect, as shown in stream table 4:
Stream table 4
The respective streams table 5 that control appliance issues to VTEP2 is two-stage stream table, IP:VTEP2 for the purpose of first order stream table occurrence; Action item is for separating VXLAN encapsulation; Second level stream table occurrence is the protocol number of message is BFD message protocol number; Action item send control appliance on being.
Stream table 5
Simultaneously, control appliance structure BFD message, and be handed down to VTEP1, trigger VTEP1 and regularly send BFD message to VTEP2, like this, the outgoing interface of BFD message coupling stream table 4 is tunnel face, thus enter and forward with the main path of this tunnel-associated, when on main path, certain link or website break down, VTEP2 would not receive the BFD message that VTEP1 sends in the given time, and then can not on send control appliance, therefore control appliance can perceive main path fault very soon, amendment stream table is sent to VTEP1, in stream table 1, the priority of the first preferred path is modified, as flowed shown in table 6:
Stream table 6
Like this, the stream table that message can mate high priority at VTEP1 is forwarded to VM2 on the second preferred path.
Because the outgoing interface of the stream table of coupling BFD message is tunnel face, forwards on the second preferred path so BFD message will mate stream table, namely detect current second preferred path.
Due to main path fault, flow has been switched on the second preferred path, at this moment needs to calculate the path made new advances, and as the standby path of the second preferred path, is implemented as:
Control appliance calculates the 3rd preferred path from VTEP1 to VTEP2 according to the network topology of collecting, the down hop of the VTEP1 on the 3rd preferred path is associated with VXLAN Tunnel with outgoing interface, the down hop of the VTEP1 on the first preferred path is carried out associating with VXLAN Tunnel with outgoing interface, and issue a stream table 7 to VTEP1, due to the first preferred path fault, so this stream table 7 covers the stream table 6 of the first preferred path, and as standby path, the priority of stream table 7 is lower than the priority flowing table 2.
Stream table 7
Like this, when on second preferred path, certain link or website break down, BFD also can fast detecting out, again can there is path to switch, therefore BFD message can forward on the standby path that the 3rd preferred path this article is new, namely by BFD packet check current standby path, i.e. the 3rd preferred path.
In a word, the solution of the present invention, after active-standby path switches, recalculates new standby path, to guarantee that subsequent packet does not interrupt.
Likely recover after first preferred path fault, the LLDP message collection network topology information that control appliance sends to it according to each OVS equipment, determine whether the first preferred path recovers, after the first preferred path recovers, the down hop of the VTEP1 on the first preferred path can associate with VXLAN Tunnel with outgoing interface by control appliance, the down hop of the VTEP1 on the 3rd preferred path is carried out associating with VXLAN Tunnel with outgoing interface, and re-issue a stream table 1 to VTEP1, the stream table 7 of this stream table covering the 3rd preferred path, and as main path, the priority of stream table 1 is higher than the priority flowing table 2.
Meanwhile, BFD message also can mate stream table and forward on the first preferred path, namely by the current main path of BFD packet check, i.e. the first preferred path.
So far, the present embodiment controls for by control appliance, stream table instructs the VXLAN network forwarded, be handed down to OVS and trigger main path and carry out BFD by control appliance controlling calculation active-standby path and detect Timeliness coverage network failure, in time VXLAN business is switched fast, reduce service outage duration.
It should be noted that, various embodiments of the present invention are to set up the unidirectional tunnel between a VTEP to the 2nd VTEP, and under realizing a VTEP, user sends message to user under the 2nd VTEP, guarantees that flow switches fast.In actual applications, the user at two ends, tunnel will realize mutual communication, for user under realizing the 2nd VTEP sends message to user under a VTEP, guarantee that flow switches fast, need to set up the reverse tunnel between the 2nd VTEP a to VTEP, specific implementation symmetry is implemented on the 2nd VTEP, does not repeat them here.
