Specific embodiment
For the sake of quoting and understanding, hereafter used in technical term explanation, write a Chinese character in simplified form or abridge and be summarized as follows:
DPDK: data plane development kit (Data Plane Development Kit).
Keepalived: being the independent process realized in User space, realizes vrrp agreement and popular height can
With one of assembly module.
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1 is a kind of flow chart of the two-node cluster hot backup control method of DPDK service disclosed by the embodiments of the present invention, referring to Fig. 1
Shown, the two-node cluster hot backup control method of DPDK service may include:
Step 101: determining that current device is main equipment or enters step 102 if main equipment for equipment, if standby set
It is standby, enter step 103.
Current device determines that itself could be executed for main equipment or standby equipment after determination according to self-role first
Meet the relevant operation of self-role.In the present embodiment, the determining current device is main equipment or standby equipment, may include:
Determine that current device is main equipment or standby equipment according to the Role Information of current device.
Step 102: sending notification packet according to preset period of time multicast.
When determining the current device is main equipment, the current device namely main equipment are needed according to preset time
Period multicast sends notification packet.The notification packet can with but be not limited to include the address VIP and priority level.
Wherein, about VIP: in two-node cluster hot backup scheme networking, in inside, main equipment and standby equipment are all independent one
Router has the IP address of oneself, but entirety is externally rendered as a virtual router, and virtual ip address is externally presented, this
Virtual ip address and the IP address of main equipment and standby equipment are different, referred to as VIP.In real work, exercised by main equipment empty
The quasi- actual work of router.
The priority level is to send the priority level of the equipment of notification packet, in the present embodiment namely main equipment it is excellent
First rank.
Step 103: receiving the notification packet that main equipment is sent.
When determining the current device is standby equipment, the current device, namely standby equipment, in main equipment fault-free
It can receive the notification packet of main equipment multicast transmission.
Step 104: when the address VIP in the notification packet is identical as itself address VIP, standby equipment judges described logical
Whether the priority accused in message is greater than own priority, if it is not, entering step 105.
Referring to above content, the VIP is main equipment and the standby common virtual ip address of equipment.
Standby equipment after the notification packet for receiving main equipment transmission, can by the notification packet the address VIP with
Itself address VIP is compared, see it is whether identical, can be without any processing if not identical.If they are the same, then illustrate to receive
To notification packet be that main equipment is sent, need to judge whether subsequent relevant operation executes according to wherein information.
Step 105: self-role is switched to master role by the standby equipment, and executes main equipment vocational work.
The case where the priority of standby equipment is greater than the priority of priority namely main equipment in the notification packet
Under, self-role switching is set master role by standby equipment, and starts to execute the vocational work of main equipment.
After standby equipment is switched to main equipment, notification packet, original master are sent also according to preset period of time multicast
Equipment judges that new main equipment priority is higher than itself, then can correspond to after receiving the notification packet that new main equipment is sent
Set standby device role for self-role switching, and close business processing.
In the present embodiment, the two-node cluster hot backup control method of DPDK service from network interface receive data after directly DPDK into
It is handled in journey, compared with the existing technology, reduces kernel protocol stack, kernel to User space caches, User space receives the phase handled
Treatment process is closed, configuration path is not only simplified, and the convergence time after malfunction occurred of DPDK service can be greatly reduced.
On the basis of the above disclosed embodiments of the present invention, Fig. 2 discloses the two-node cluster hot backup control of another DPDK service
Method flow diagram processed, as shown in Fig. 2, the two-node cluster hot backup control method of DPDK service may include:
Step 201: determining that current device is main equipment or enters step 202 if main equipment for equipment, set if standby
It is standby, enter step 203.
Step 202: sending notification packet according to preset period of time multicast.
Step 203: receiving the notification packet that main equipment is sent.
Step 204: when the address VIP in the notification packet is identical as itself address VIP, standby equipment judges described logical
Whether the priority accused in message is greater than own priority, if it is not, entering step 205.
Wherein the VIP is main equipment and the standby common IP address of equipment.
Step 205: self-role is switched to master role by the standby equipment, and executes main equipment vocational work.
Step 206: the number for not receiving main equipment notification packet continuously is reset to 0.
In the present embodiment, configuration in a device is needed in advance not receive the number of main equipment notification packet, the company continuously
The continuous number initial value for not receiving main equipment notification packet is 0, and standby equipment is each time in the notice report for receiving main equipment transmission
The number for not receiving main equipment notification packet continuously is reset to 0 by Wen Hou.
In addition, the present embodiment can also be pre-configured with the time interval that equipment sends or receives notification packet, namely default
Time cycle is not received by the notification packet of main equipment transmission in preset period of time each time for equipment, can will be described
The number for not receiving main equipment notification packet continuously adds 1.
Step 207: judge whether the number for not receiving main equipment notification packet continuously is greater than or equal to default value,
If so, entering step 205.
It is described to judge whether the number for not receiving main equipment notification packet continuously is greater than or equal to default value, specifically
It may include: whether the judgement continuous time for not receiving main equipment notification packet is greater than or equal to N number of preset period of time, it is described
N is equal to the default value.
If illustrating to lead for the notification packet for all not receiving main equipment transmission in equipment continuously several preset period of time
Equipment may have already appeared failure, or there is currently no main equipments, in this case, standby equipment by self-role switch based on set
Standby role, and main equipment vocational work is executed, to provide normal service.
In the present embodiment, the number for not receiving main equipment notification packet continuously is pre-set in a device, in the company
When the continuous number for not receiving main equipment notification packet is met certain condition, determines master-failure or there is no main equipments, it is standby to set
It is standby that self-role is switched to main equipment, to provide normal service.
