Description
Technical field
The present invention relates to the network communications technology, particularly realize method, system and the equipment of Virtual Router Redundancy Protocol (VRRP:Virtual Router Redundancy Protocol) load-sharing mode (VRRPE:Virtual RouterRedundancy Protocol Extended) traffic transport.
Background technology
Standard VRRP forms a virtual router (also claiming the VRRP backup group) with a plurality of routing devices with gateway function, a plurality of routing devices in this virtual router elect one as primary route equipment (master) according to the VRRP election mechanism, being used for being responsible for flow transmits, other are as alternate routing equipment (backup), can not converting flow, only be responsible for the master routing device is monitored, and, re-elect master listening to the master routing device when breaking down.As can be seen, in standard VRRP,, just need to create a plurality of VRRP backup groups if realize load balancing between a plurality of routing devices.But, transmit owing to have only the master routing device to be responsible for uplink traffic in the VRRP backup group, obviously on the routing device resource and the network bandwidth, all there is waste.
The VRRP load-sharing mode that grows up gradually can solve above-mentioned waste problem, wherein, the VRRP load-sharing mode is on the virtual gateway redundancy backup basis that VRRP provides, increased load-balancing function, it realizes that principle is: create a VRRPE backup group, the corresponding virtual ip address of this VRRPE backup group, afterwards, this virtual ip address is corresponding with a plurality of virtual mac address, just be each the routing device configuration corresponding virtual MAC Address in the VRRPE backup group, so that each routing device can both converting flow in the VRRPE backup group.As can be seen, in the VRRP load-sharing mode, only need to create a VRRPE backup group, just can realize the load balancing between a plurality of routing devices in the VRRPE backup group, avoided that backup is in the not high problem of idle condition, network resource utilization all the time in the VRRP backup group.
In the VRRP load-sharing mode, also be to elect master according to the VRRPE election mechanism, other as backup, wherein, master is responsible in the VRRPE backup group all routing devices and distributes virtual mac address in the VRRPE backup group, and is from the different virtual mac address of the address resolution request-reply of different main frames according to load-balancing algorithm.Wherein, the address resolution request can be asked for ARP in IPv4, and the address resolution request can be found (ND:NeighborDiscovery) request for neighbours in IPv6, thereby the realization flow is shared between a plurality of routing devices.
Such as, in the VRRPE network architecture shown in Figure 1, routing device A to C is in the same VRRPE backup group, wherein, the virtual ip address of this VRRPE backup group is 10.1.1.1/24 (for main frame, being also referred to as virtual gateway), elects master according to the VRRPE election mechanism from routing device A to C, here be master with routing device A, routing device B to C is backup.So, master is that routing device A to C distributes different virtual MAC (VMAC) addresses, is respectively VMAC1 to VMAC3, and these three VMAC addresses are that 10.1.1.1/24 is corresponding with above-mentioned virtual ip address respectively.With IPv4 is example, receive the ARP request of main frame (Host) A, Host B or Host C transmission as master after, obtain the VMAC address of virtual ip address 10.1.1.1 correspondence, master is according to load-balancing algorithm, utilize different VMAC addresses to reply and send the main frame that this ARP asks, for example, after master obtains the ARP request that Host A sends, the A to Host is replied in the VMAC address of routing device A; Obtain the ARP request of Host B transmission as master after, the B to Host is replied in the VMAC address of routing device B; Obtain the ARP request of Host C transmission as master after, the C to Host is replied in the VMAC address of routing device C.
So, get access to the VMAC address of routing device A as Host A after, think that the MAC Address of gateway is that the VMAC address of routing device A is VMAC1, so, the uplink traffic that Host A sends is all passed through routing device A forwarding, and promptly routing device A is the forwarding gateway of Host A; Get access to the VMAC address of routing device B as Host B after, think that the MAC Address of gateway is that the VMAC address of routing device B is VMAC2, so, the uplink traffic that Host B sends all pass through routing device B forwarding, and promptly routing device B is the forwarding gateway of Host B; Get access to the VMAC address of routing device C as Host C after, think that the MAC Address of gateway is that the VMAC address of routing device C is VMAC3, so, the uplink traffic that Host C sends all pass through routing device C forwarding, and promptly routing device C is the forwarding gateway of Host C.This has realized the load balancing of uplink traffic between a plurality of routing devices.
But, at downlink traffic, in the prior art, no matter be standard VRRP, or VRRPE, all requiring a plurality of routing devices of same backup group is the identical interface IP address network segment route of center routing device issue to the upper layer device that has connected this backup group, that is to say, the center routing device is an equal-cost route to the route of a plurality of routing devices of same backup group, based on this, the center routing device can be selected one at random and come the converting downlink flow when sending downlink traffic to main frame from equal-cost route.Still with shown in Figure 1, then the route between center routing device and the routing device A to C is an equal-cost route, when external request when Host B sends downlink traffic, the center routing device is selected one at random from equal-cost route, ratio as shown in phantom in Figure 2, select the route between this center routing device and the routing device A, so, this downlink traffic just goes downwards to Host B by routing device A.But, can know that according to top description the forwarding gateway of Host B is routing device B, i.e. the uplink traffic of Host B transmission is transmitted by routing device B, and this asymmetric situation of up-downgoing flow path of same main frame obviously occurred.If in common local area network (LAN), the gateway of main frame is that ordinary router or three-tier switch (not preserving session information) are acceptables.But in data center network, the gateway of main frame has all disposed flow control usually such as fire compartment wall etc., and flow control will inevitably be preserved session information in order to control flow better.So, when the asymmetric situation of up-downgoing flow path of same main frame recited above occurring, it is packet loss directly, and this can cause service traffics to be interrupted.

Technical scheme provided by the invention relates in the network architecture that comprises center routing device and a plurality of routing devices, described center routing device is in the upper strata of routing device, and plural routing device composition VRRPE backup group in the described network architecture is set according to the actual requirements; Based on this, as shown in Figure 3, this flow process can comprise:
Routing device is determined with from as the main frame of transmitting gateway in the step 301, VRRPE group, and the sign of this main frame of determining is sent to the center routing device.
Here, routing device is the forwarding gateway of main frame, is essentially this routing device and is used to transmit flow from this main frame.As for routing device concrete as how self for transmitting the main frame of gateway, referring to following step 406 to step 409.
Step 302 after the center routing device receives described host identification, is set up the route that arrives described main frame, and when receiving the flow that is sent to described main frame, according to this flow of routing forwarding of setting up.
Here, the route next jump of the arrival main frame of foundation is corresponding with the routing device that sends this host identification.
Figure 1 shows that example,, then determine that promptly routing device B transmits the flow from this Host B from as the forwarding gateway of Host B the time as routing device B according to step shown in Figure 3; It can send the sign of Host B to the center routing device in step 301; When carrying out step 302, the center routing device can be set up the route that arrives Host B, and wherein, the next hop address of this route is the address of routing device B.So, when center pathway need send downlink traffic to Host B by equipment, it can be specially: this downlink traffic is sent to routing device B according to this downlink traffic of routing forwarding of having set up; Finally send downlink traffic to Host B by this routing device B.And can know that according to top description routing device B is the forwarding gateway of Host B, and that is to say, transmit by routing device B from the uplink traffic of this Host B.Based on this, as can be seen, in the present embodiment no matter be the downlink traffic that the center routing device mails to Host B, still Host B mails to the uplink traffic of center routing device, the forwarding gateway that Host B is all passed through in the path of its transmission is routing device B, and this has obviously realized the up-downgoing traffic transport path symmetry of same main frame.
More than method that the embodiment of the invention is provided carried out simple description, the method that the embodiment of the invention is provided is described in detail below.
Referring to Fig. 4, the detail flowchart that Fig. 4 provides for the embodiment of the invention.This flow process is applied to comprise in the network architecture of N routing device, and wherein, N is a positive integer, and it is more than or equal to 2, and as shown in Figure 4, this flow process can may further comprise the steps:
In the embodiment of the invention, make the routing device that has disposed VRRPE constitute a VRRPE backup group.
Here, the concrete way to elect of step 402 can for: elect any one to move normal routing device as master, perhaps elect performance the highest as master, perhaps the VRRP priority according to defined routing device in the VRRPE agreement conducts an election etc.With VRRP priority is the election operation that example is described step 402: such as, the priority of routing device A to D is respectively 100,90,60,50, according to the routing device with greatest priority is master, then electing routing device A is master, and other routing devices are that routing device B to D is backup.
Here, execution in step 403 why mainly is for VRRPE and BGP are linked, and to guarantee the up-downgoing traffic transport path symmetry of same main frame, it is described specifically to see below.
Need to prove that above-mentioned steps 402 and step 403 there is no the regular time sequencing.
By step 404 and step 405 as can be seen, the virtual MAC address of each routing device is a dynamic assignment, when in a single day routing device is converted into master, if self still is not assigned with the virtual MAC address, then in the virtual MAC address realm that sets in advance, distribute a still untapped virtual MAC address to give self; In addition, if backup is not assigned with the virtual MAC address, then can send request (request) message to the master routing device, after master receives this request message, distribute a still untapped virtual MAC address to give this backup in the virtual MAC address realm that sets in advance, the virtual MAC address of this distribution is carried to reply in (Reply) message and sends to backup.
Here, the address resolution request can be the ARP request in IPv4, it can be arp reply that address resolution is replied, after main frame receives arp reply, utilize the virtual MAC address in this arp reply to make up the ARP list item, so that follow-up this ARP list item that utilizes carries out the transmission of uplink traffic, promptly follow-up uplink traffic from this main frame all sends by the routing device with this virtual MAC address; The address resolution request can be that neighbours find (ND in IPv6, Neighbor Discovery) request, it can be that ND replys that address resolution is replied, main frame receives after ND replys, utilize the virtual MAC of this ND in replying to make up the ND list item, so that follow-up this ND list item that utilizes carries out the transmission of uplink traffic, promptly follow-up uplink traffic from this main frame all sends by the routing device with this virtual MAC address.
Need to prove, in the present embodiment, the All hosts that the VRRPE backup group is hung down all sends the address resolution request to master, in order to realize this operation, in the above-mentioned steps 401 after constituting the VRRPE backup group, also needing further be virtual IP address of this VRRPE backup group configuration, and the default gateway IP address configuration of the All hosts that this VRRPE backup group is hung down is this virtual IP address, and this can guarantee all master transmission address resolution requests in same VRRPE backup group of each main frame.Be depicted as example with Fig. 5 a, three main frames of current existence, be respectively host A to C, wherein, this host A to the identical configuration of C employing is that the default gateway IP address configuration of each main frame is this virtual IP address, like this, shown in the dotted line among Fig. 5 a, this host A all can send the address resolution request to the master among the same VRRPE to C.So, in this step 406, after master received address resolution request from main frame, the virtual MAC address that will distribute at least one routing device in the described VRRPE backup group according to the load balancing strategy was carried at address resolution and replies to described main frame in replying.Wherein, this load balancing strategy can adopt multiple mode, such as adopting poll load balancing strategy, promptly successively the virtual MAC address of each routing device is replied to the main frame that sends the address resolution request according to fixing order and gets final product; Perhaps adopt weighting load balancing strategy, soon the message transfer capability of each routing device and/or present load situation select the virtual MAC address to reply to the main frame that sends the address resolution request as weighted factor.
With poll load balancing strategy is example, and when then carrying out this step 406, if master receives the address resolution request of host A, then the virtual MAC address with routing device A replies to host A; Receiving the address resolution request of host B, then the virtual MAC address with routing device B replies to host B; Receiving the address resolution request of host C, then the virtual MAC address with routing device C replies to host C.
Here, master can regularly back up described mapping table on all backup.Preferably, if mapping table is updated, then master also can be synchronized on all backup in real time.
Here, routing device can comprise master and backup in the VRRPE group in the VRRPE group.Wherein, the IP address of the main frame that obtains of routing device serves as the IP address of transmitting the main frame of gateway with this routing device just.
Here, can know that the upstream Interface of routing device has disposed IBGP in the VRRPE group, and has set up the peer relation with the center routing device, based on this, knows that obviously the opposite end bgp neighbor is the center routing device in the step 409 according to step 403.
Be respectively IP1, IP2 and IP3 with the host A shown in Fig. 5 a to the IP address of host C, and, it is example that the virtual MAC address that the virtual MAC address that the virtual MAC address of routing device A replies to host A, routing device B replies to host B, routing device C replies to host C, and what then routing device A carried out in the step 409 is advertised as: next jumping of IP1 (NextHop) routing device A no-advertise;
What routing device B carried out is advertised as: IP2 NextHop routing device B no-advertise;
What routing device C carried out is advertised as: IP3 NextHop routing device C no-advertise.
Wherein, routing device mainly is for the host IP address that obtains is announced to the center routing device in the VRRPE group, so that guarantee the up-downgoing traffic transport path symmetry of follow-up same main frame, it need not allow other device learns again, based on this, all adopt the no-advertise mode in the above-mentioned announcement, i.e. the equipment that this announcement is received in expression can not be announced the opposite end bgp neighbor to other again.
Be advertised as example based on what each routing device of the description in the step 409 was carried out, when then carrying out this step 411, the detailed route of learning is:
Next jumps NextHop routing device A ■ destination address IP1
Next jumps NextHop routing device B ■ destination address IP2
Next jumps NextHop routing device C ■ destination address IP3
So far, realized that by above-mentioned steps center pathway is arrived the operation of the route of main frame by learning equipment.Need to prove that the route of study is 32 main frame routes in the step 410, such as network segment route etc., its priority is the highest, and this main frame route can not spread out yet than other routes.
Step 411 is when main frame need be to outside Network Transmission uplink traffic, to transmit this uplink traffic from the pairing routing device in virtual MAC address that is assigned with in step 406.
Shown in Fig. 5 a, when the virtual MAC address that host A obtains in step 406 is the virtual MAC address of routing device A, then when host A need be to outside Network Transmission uplink traffic, it obviously can transmit this uplink traffic to routing device A.
Step 412, when center pathway received the downlink traffic that sends to main frame by equipment, it was according to this downlink traffic of detailed routing forwarding from foundation in step 410.
Shown in Fig. 5 a, when center pathway receives the downlink traffic that sends to host A by equipment, detailed route according to above-mentioned steps 410 foundation, can know, next of this route jumped and is routing device A, be in this step 412, the center routing device is transmitted this downlink traffic to routing device A, transmits this downlink traffic to host A by routing device A.
By the description of above-mentioned steps 411, can know that present embodiment can be realized the up-downgoing traffic transport path symmetry of same main frame, specifically sees shown in Fig. 5 b to step 412.
