The realization of the message forwarding method of the present embodiment make use of distributed aggregated link technology, here to distributed link
Polymerization technique is briefly described.
Link aggregation (Link Aggregation), refers to bundle multiple physical ports, turns into a logic
Port, to realize load sharing of the in/out flow in each member port.Link aggregation technology is frequently used on interchanger,
Interchanger is sent to the exchange of opposite end according to the port load-sharing strategy decision message of user configuration from which member port
Machine.When interchanger detects that the link of one of member port breaks down, just stop sending message on this port, and
The member port of message can be sent by being recalculated according to load-sharing strategy, by port transmission of the message through newly calculating, treat event
The port of barrier calculates the member port that can send message again after recovering, and ensure that each member of the service traffics in link aggregation
Shared between port.From the foregoing, it will be observed that link aggregation technology is an increase link bandwidth, realizes that link transmission elasticity and redundancy are very heavy
The technology wanted.
Distributed aggregated link technology refers to that wherein one end of link aggregation is not unit, but two or more
Equipment.As shown in Fig. 2 one end of link aggregation, device A has two physical ports to add link aggregation, forms a polymerization end
Mouthful.The other end of the other end of link aggregation, i.e. device A is two physical equipments, is equipment B and equipment C respectively, and set
Standby B and equipment C has a physical link to add aggregation port, and in device A, they are an equipment, still, in fact,
It is understood that this is two independent equipment, in this way can with during an equipment fault wherein by the stream in device A
Amount is forwarded by another normal equipment, improves equipment B and equipment C overall service reliability.
Figure it is seen that can to pass through distributed aggregated link (or distributed for CE A to CE E flow forwarding
Link aggregation group) any one equipment, as VTEP B or VTEP C are forwarded.Before VTEP B in Fig. 2, VTEP C are
The edge device of VXLAN described in face.After an equipment fault in distributed aggregated link, business is not being interfered with just
Often operation, but work is taken over by an other equipment, so as to be advantageous to the data transfer of stack equipment.

From the foregoing, it will be observed that the reliability of data forwarding can be ensured to a certain extent by distributed aggregated link technology.But
It is that referring to Fig. 2, after the even whole link failures of the link failure between the equipment C and equipment D in Fig. 2, device A is to setting
If the service traffics of standby D forwardings have been sent to after Hash calculation on equipment C, equipment C will be unable to be turned to equipment D
Hair, cause equipment C to equipment D flow to forward and interrupt, and then traffic affecting normal operation.
For this problem, the present embodiment proposes a kind of method that message forwarding is carried out based on distributed aggregated link.When
The first equipment in distributed paradigmatic system and after the public network tunnel fails of connected remote equipment, can pass through
Enter in the first equipment of the distributed aggregated link system of failure with establishing new VXLAN tunnels between the remote equipment of public network
Row flow is forwarded, and the business of ensure that can be normally carried out, and improve the reliability of network.
With reference to Fig. 2 and Fig. 3, equipment C and equipment D belongs to the first VXLAN networks in the present embodiment, and first on equipment C
The message of business is forwarded to equipment D by the 2nd VXLAN tunnels (tunnel).The destination address in the 2nd VXLAN tunnels here
For 4.4.4.4 (i.e. equipment D IP address), the next-hop in the 2nd VXLAN tunnels is also 4.4.4.4 direct-connected next-hop.Equipment C
When public network tunnel is normal between equipment D, the message of the first business on equipment C is forwarded on equipment D by public network tunnel.
According to the method for the present embodiment, judge public network tunnel between equipment C and equipment D whether failure, when judging to set
After standby public network tunnel failure (e.g., down falls) between C and equipment D, the is established according to the address of the distal end VTEP equipment of acquisition
One virtual expansible LAN VXLAN tunnels, carry out across the foundation in the VXLAN tunnels of distributed paradigmatic system and message forwarding.
