The embodiment of the present invention proposes a kind of method for configuring route, and this method configures the RT of tenant's VPN instance by controller
Attribute, meanwhile, the routing policy (RT attribute is arranged to the routing from different outer net equipment) of outer net VPN instance is configured, so that
RT attribute is arranged to received routing according to routing policy in gateway, and by the RT of the RT attribute of routing and tenant's VPN instance
Attribute is matched, and routing is added in the VPN instance of tenant after successful match, and tenant's flow is guided to forward to outer net.
It is one embodiment flow chart of method for configuring route of the present invention referring to Fig. 1, the embodiment is from SDN controller side
Routing configuration process is described.
Step 101, the routing policy of outer net VPN instance is configured.
VPN is a kind of virtual private network technology, and the routing isolation between different VPN passes through VPN instance (VPN-
Instance it) realizes.Each VPN instance has relatively independent routing table and LFIB (Label Forwarding
Information Base, tag forwarding information base), it is ensured that the independence and safety of VPN data.
Information in VPN instance may include: LFIB, IP route table and the associated interface of VPN instance and VPN instance
Management information in any one or it is multiple.The management information of VPN instance may include RD (Route
Distinguisher, Route Distinguisher, for distinguishing the identical address prefix of different VPN), VPN Target (also known as
Route Target, abbreviation RT, for controlling the publication of VPN routing iinformation) attribute, in route filtering strategy any one or
It is multiple.
In the present invention, SDN controller is configured with outer net VPN instance in gateway, which configures in net
On the outgoing interface for closing equipment connection outer net equipment (for example, PE equipment).Gateway passes through the outer net VPN instance and outer net equipment
VPN instance neighbours are established, the routing for the publication of receipt of subsequent outer net equipment is prepared.
In this step, SDN controller is that outer net VPN instance configures routing policy, and the routing policy of the outer net VPN instance is used
In make gateway to from different outer net equipment routing be arranged RT attribute.For example, being set to the routing from outer net equipment PE1
Setting RT attribute is 1:1, is 2:2 to the routing setting RT attribute from outer net equipment PE2.
Step 102, the RT attribute of tenant's VPN instance is configured.
SDN controller is configured with corresponding VPN instance, abbreviation tenant's VPN instance in gateway for each tenant.
In this step, SDN controller can configure one or more RT attribute for tenant's VPN instance.
Step 103, the RT attribute of the routing policy of the outer net VPN instance and tenant's VPN instance is handed down to
Gateway.
The configuration information of step 101 and step 102 is handed down to gateway by SDN controller.
After gateway establishes neighborhood by outer net VPN instance and outer net equipment, the road of outer net equipment publication is received
By, and RT attribute is arranged to received routing according to the routing policy of outer net VPN instance.Then, judging the RT attribute of routing is
It is real to be added to tenant VPN after determining RT attributes match by the no RT attributes match with tenant's VPN instance for the routing received
In example, tenant's flow is guided to forward according to the routing in tenant's VPN instance to outer net.
Optionally, in another embodiment of the invention, the routing of tenant's VPN instance can be further configured in SDN controller
Strategy, the routing policy of tenant's VPN instance the routing being added in tenant's VPN instance are arranged according to the RT attribute of routing excellent
First grade.For example, be that tenant selects PE1 for main PE when SDN controller selects active and standby mechanism, PE2 is from PE, then the tenant VPN
The routing policy of example can be with are as follows: the routing (routing from PE1) of setting RT attribute 1:1 is high priority, and RT attribute is arranged
The routing (routing from PE2) of 2:2 is low priority.
The routing policy of tenant's VPN instance of configuration is handed down to gateway by SDN controller.Gateway is according to tenant
Priority is arranged to the routing being added in tenant's VPN instance in the routing policy of VPN instance, then in subsequent boots tenant's flow
When, matching high priority is routed to be forwarded to outer net.When high priority routing respective links are unreachable, gateway ceases to be in force automatically
High priority routing, come into force time high priority routing, guides tenant's flow according to the routing forwarding newly to come into force, that is, to realize
The active and standby mechanism of a plurality of routing.
If SDN controller is not configured routing priority, gateway using a plurality of routing in tenant's VPN instance as etc.
Valence routing, realizes load balancing.It is not emphasis of the present invention that how specific tenant's flow, which matches equivalent route forwarding, no longer superfluous herein
It states.
In addition, SDN controller can configure the RT attribute exclusively enjoyed for tenant's VPN instance, for example, RT attribute 1:1 is only configured
To tenant 1, then the routing from PE1 can only be added in the VPN instance of tenant 1, i.e., tenant 1 exclusively enjoys PE1 and carries out outer net flow
Forwarding.
It should be added that the RT attribute of SDN controller configuration tenant's VPN instance, specifically can include: determine gateway
The state for the outgoing interface being connect in equipment with outer net equipment；The outgoing interface being connect with outer net equipment according to the state pair of outgoing interface into
Row sequence configures tenant's VPN instance according to the RT attribute for the outer net equipment that the selection that puts in order of outgoing interface is connect with outgoing interface
RT attribute.That is, the outgoing interface of selection state optimization forwards tenant's flow.Wherein, outgoing interface state can according to go out connect
Up (enabling)/down (disabling) state of mouth and the bandwidth rates of outgoing interface determine.For example, when outgoing interface is in UP state,
It is ranked up from large to small according to remaining bandwidth rate；Select outgoing interface up and the maximum outgoing interface (state of remaining bandwidth rate
Optimal outgoing interface) connection outer net equipment RT attribute, configure tenant's VPN instance RT attribute.
SDN controller monitors outgoing interface state in real time, when the corresponding outgoing interface of RT attribute of tenant's VPN instance is in down
When state, the RT attribute of tenant's VPN instance is deleted, retriggered configures the RT attribute of tenant's VPN instance, that is, flows tenant
Amount matches more excellent route always and forwards to outer net.Specifically, the RT attribute of retriggered configuration tenant's VPN instance, still uses
The method of above-mentioned offer, it may be assumed that determine the state for the outgoing interface connecting in gateway with outer net equipment；According to the state of outgoing interface
The outgoing interface connecting with outer net equipment is ranked up, is set according to the outer net that selection is connect with outgoing interface that puts in order of outgoing interface
Standby RT attribute configures the RT attribute of tenant's VPN instance.More specifically, it can be carried out from large to small according to remaining bandwidth rate
Sequence；The RT attribute for selecting outgoing interface up and the outer net equipment of the maximum outgoing interface connection of remaining bandwidth rate, configures tenant VPN
The RT attribute of example.
It can be seen from the above description that the present invention configures the VPN instance in gateway by SDN controller,
It realizes the dynamic addition routed in gateway, provides a plurality of optional path forwarding for tenant's flow.
Now for SDN network, routing configuration process is introduced shown in Fig. 2.Illustrating SDN network includes virtual machine VM1~VM4
(Virtual Machine, abbreviation VM), virtual swap device OVS1 and OVS2 (Open vSwitch, abbreviation OVS), SDN control
Device, gateway GW (Gateway, abbreviation GW), outer net equipment PE1~PE4 (Provider Edge, abbreviation PE).Gateway
BGP (Border Gateway Protocol, Border Gateway Protocol) agreement is run on GW.
It is assumed that having created outer net VPN instance on GW, be denoted as ExtVPN, and at the ExtVPN respectively with PE1~PE4
Establish neighborhood.SDN controller can configure routing policy, the enabled routing received from different PE for different neighbours
Different RT is set.Such as: SDN controller is that ExtVPN configures routing policy, is denoted as Policy1, which is specially pair
Routing setting RT attribute from PE1 is 1:1；It is 2:2 to the routing setting RT attribute from PE2；Routing from PE3 is set
Setting RT attribute is 3:3；It is 4:4 to the routing setting RT attribute from PE4.SDN controller is issued by netconf agreement
The Policy1 of ExtVPN is to GW.
When increasing tenant User1 (renting VM1) in SDN network newly, the VPN that SDN controller creates User1 on GW is real
Example, is denoted as UserVPN1, and configure the RT attribute of UserVPN1.It is assumed that the RT attribute of configuration is 1:1 and 2:2, pass through
Netconf agreement issues the RT attribute of UserVPN1 to GW.
When GW receives routing (being denoted as R1) from PE1, belonged to according to the RT that R1 is arranged in the routing policy Policy1 of ExtVPN
Property is 1:1, and the RT attribute of R1 is matched with the RT attribute 1:1 in UserVPN1, and therefore, R1 is added in UserVPN1.Similarly,
The routing (being denoted as R2) that GW is received from PE2 is 2:2, R2 according to the RT attribute that R2 is arranged in the routing policy Policy1 of ExtVPN
RT attribute matched with the RT attribute 2:2 in UserVPN1, therefore, R2 is added in UserVPN1.So far, in UserVPN1
There are two routing R1 and R2.This two routings can be guided the flow of User1 to forward to outer net by GW as equivalent route.
Certainly, above-mentioned two routings can also be regard as main standby route.Specifically it can configure UserVPN1's by SDN controller
Routing policy Policy2, the Policy2 are specially excellent according to the setting of the RT attribute of routing to the routing being added in UserVPN1
First grade, for example, the priority for the routing that setting RT attribute is 1:1 is high priority；The priority for the routing that RT attribute is 2:2 is
Default priority, i.e. low priority.
Optionally, it when priority is arranged, can be configured by number, such as digital big, the priority that priority is high
Low number is small, and then the priority of routing can be determined by comparing Digital size.
SDN controller issues the routing policy Policy2 of UserVPN1 to GW by netconf agreement.Then GW to
It is 7 according to the priority that R1 is arranged in the Policy2 of UserVPN1 when UserVPN1 addition routing R1；When addition routing R2, according to
The priority of the Policy2 setting R2 of UserVPN1 is default priority 0.High priority routing R1 comes into force in GW, low priority
R2 failure is routed, the flow matches R1 of User1 is forwarded to outer net.When the next-hop of R1 is unreachable, R1 failure, R2 comes into force,
The flow of User1 can be forwarded by R2 to outer net, and the purpose of main standby route is played.
It should be noted that the priority of R1 is the default priority 0 of 7 and R2, therein digital 7 and digital 0 only
It is for example, should not be as limitation.
It should be added that the RT attribute of the dynamically configurable UserVPN1 of SDN controller.Specifically, SDN controller
It can be connect by the Openflow between GW, obtain the outgoing interface connecting on GW with PE equipment (it is assumed that connecting with PE1~PE4
Outgoing interface be respectively Interface1~Interface4) state, including UP/DOWN state, interface bandwidth rate etc..When
Outgoing interface is in up state, and remaining bandwidth is greater than preset threshold, i.e., when remaining bandwidth is more, the state of the outgoing interface is more excellent.
It is ranked up according to outgoing interface state, selects the state preferably RT attribute configuration UserVPN1's of the PE equipment of outgoing interface connection
RT attribute.It is assumed that outgoing interface state from excellent to bad put in order for Interface1, Interface2, Interface3,
Interface4, SDN controller are intended to be UserVPN1 and configure two RT attributes, then by the RT for the PE1 connecting with Interface1
Attribute 1:1, the PE2 being connect with Interface2 RT attribute 2:2 be allocated to UserVPN1, for User1 provide high quality turn
Send out path.
It is assumed that SDN monitoring control devices Interface1 is in down state, then the RT attribute of UserVPN1 can be actively deleted
1:1 reselects the state preferably RT attribute of outgoing interface configuration UserVPN1, for example, according to outgoing interface state sequencing selection
The RT attribute of the RT attribute 3:3 configuration UserVPN1 for the PE3 being connect with Interface3, at this point, configured in UserVPN1 two
A RT attribute is 2:2 and 3:3, to guarantee the transfer quality of the flow of User1.
