Description
Technical Field
The invention relates to the technical field of data processing, in particular to an IaaS OverLay control plane implementation method based on open source EVPN.
Background
With the rapid development of information technology, the construction of data centers has gone through decades of history. Server architectures in fact currently in use have been in use for decades and problems have emerged. The advent of blade servers has brought forward one step in the architectural design of servers; but also presents a decentralized storage resource utilization problem. The data center has a plurality of network devices, storage devices, and the like, which are connected through a network, but are still separated from each other. The integration and optimization of data center equipment, the intensification and the integrated design have already mentioned the schedule. The efficiency of the server and the efficiency of the whole data center are improved, energy is saved, consumption is reduced, the integral cost of ownership (TCO) is reduced, meanwhile, the response speed and the operation efficiency of the data center for improving the service are improved, the structural design of the data center and the system of the server needs to be changed, and the development of the cloud computing technology well meets the changing requirement.
At present, in a cloud data center, a vxlan encapsulation technology is generally adopted, but for the BUM traffic of a virtual machine, the network pressure is not reduced only by the flooding of a forwarding plane.
Disclosure of Invention
In order to solve the above technical problems, an object of the present invention is to provide a method for implementing an IaaS OverLay control plane based on an open source EVPN.
The technical scheme adopted by the invention for solving the technical problems is as follows: an IaaS OverLay control plane implementation method based on open source EVPN is characterized in that an ultra-large data center is partitioned into a plurality of different area server groups, servers of each area are interconnected through 802.1Q sub-interfaces to provide vlan of the area, namely vlan 802.1Q encapsulation is adopted when vm of the area is in cross-host communication, vxlan encapsulation is adopted when cross-area communication is performed, a server is taken in each area to serve as a vtep point and an EVPN control point of vxlan, vtep of the area learns vm mac of the area through sniffing, and far-end vm mac learning is known through mpbgp-EVPN declaration by an opposite end.
The invention has the beneficial effects that: compared with the prior art, the IaaS OverLay control plane implementation method based on the open source EVPN provided by the invention has the advantages that the open source EVPN-golone is practiced, the open source EVPN is utilized to provide a control plane for vxlan, and the pressure brought to underlay by the flooding of a forwarding plane is reduced.
Detailed Description
Example 1
An IaaS OverLay control plane implementation method based on open source EVPN is characterized in that an ultra-large data center is partitioned into a plurality of different area server groups, servers of each area are interconnected through 802.1Q sub-interfaces to provide vlan of the area, namely vlan 802.1Q encapsulation is adopted when vm of the area is in cross-host communication, vxlan encapsulation is adopted when cross-area communication is performed, a server is taken in each area to serve as a vtep point and an EVPN control point of vxlan, vtep of the area learns vm mac of the area through sniffing, and far-end vm mac learning is known through mpbgp-EVPN declaration by an opposite end.
The invention has the beneficial effects that: compared with the prior art, the IaaS OverLay control plane implementation method based on the open source EVPN provided by the invention has the advantages that the open source EVPN-golone is practiced, the open source EVPN is utilized to provide a control plane for vxlan, and the pressure brought to underlay by the flooding of a forwarding plane is reduced.
Example 2
In the ultra-large data center, two areas, namely an area A server group and an area B server group are assumed
The server of each zone provides interconnection for the vlan of the zone through the 802.1Q sub-interface, namely the vlan 802.1Q package adopted by the vm of the zone during cross-host communication, but the vxlan package adopted during cross-zone communication
Respectively taking one server in the area A and the area B as a vtep point and an evpn control point of vxlan
The vtep of the local area learns the vm mac of the local area by sniffing
And the far-end vm mac learning is known by the opposite end through mpbgp-evpn announcement
In specific practice, 2 server tests are adopted, and we assume that br100 and br1000 belong to the same vlan segment
br200 and br2000 belong to the same vlan segment (if br1000 and br2000 are placed on other servers, they may be renamed as br100 and br200, br100 adopts 802.1q sub-interface package when communicating across servers)
Experiment with namespace replacement for VM
Environment:
the above embodiments are only specific examples of the present invention, and the protection scope of the present invention includes but is not limited to the forms and styles of the above embodiments, and any suitable changes or modifications made by those skilled in the art according to the present invention should fall within the protection scope of the present invention.
