Description
Technical field
The present invention relates to a kind of network switch technologies, and in particular to a kind of the distributed virtual switch and configuration method.
Background technique
The network switch is the key equipment of network consisting system, and more connectivity ports are provided between each network,
To connect more computers.With the development of internet and information-intensive society, networking number of computers is continuously increased, to network
The demand of switch device constantly rises situation.Interchanger is divided into two kinds: wide-area network switch and LAN switch.Wide area network
Interchanger is mainly used in field of telecommunications, provides communication infrastructure platform.And LAN switch is then applied to local area network, is used for
Connect terminal device, such as PC machine and the network printer.
The major function of interchanger includes physics addressing, network topology structure, error checking, frame sequence and flow control.Mesh
Preceding interchanger has been also equipped with some new functions, such as support to VLAN (virtual LAN), the support to link aggregation, even
Some also has the function of firewall.Interchanger, can also be in different type other than it can connect same type of network
Network (such as Ethernet and Fast Ethernet) between play the role of interconnection.Nowadays it is quick can to provide support for many interchangers
The high speed connectivity port of Ethernet or FDDI etc., for connecting other interchangers or the pass big for bandwidth usage in network
Key server provides additional bandwidth.
Cloud computing is huge calculation processing program to be split into multiple lesser subprograms by network, then taken by multi-section
Processing result is returned into user after system-computed analysis composed by business device.By this technology, long-range service provision
Quotient can reach information of the processing number in terms of necessarily or even in terms of hundred million, reach equally powerful with mainframe computer within the several seconds
The network service of performance.For constructing the platform software OpenStack of cloud computing environment in layer architecture, modularization and open sourceization
On have a greater advantage, virtual network, which sets up Nova, has a network AP I abundant, user can by Configuration network and subnet come
The network topology of multiplicity is created, there is very high flexibility and practicability.But for the network configuration of the above technology, still
There is deficiency:
1) interchanger for constructing system for cloud computing environment is all physical equipment, and physical switches are function-specific special
With equipment, it can be only done specific net connection function, have a single function, other function can not be configured, it is inflexible for use.
2) building system for cloud computing environment is complicated distributed network system (DNS), needs to couple the calculating of a large amount of strange land arrangements
Machine, it is therefore desirable to which a large amount of physical switches provide net connection, and equipment spends more, high construction cost, maintenance difficulties are big.
3) physical switches are before use, need user using the interactive mode of order line come to network configuration, low efficiency and
Complicated api command learning cost is higher.Network portion concept is many and diverse, contains network node installation and manages, network partition,
Double layer network (vlan/vxlan) configuration, three-layer network configure (ip etc.), configuration (including physical network and the three-layer network of upper networking
Network configuration) etc., excessively dispersion and complexity.So that using and operating for interchanger is very many and diverse, user's use is more more troublesome.
