Description

EIP classification method and system based on service types

Technical Field

The invention relates to the field of cloud computing, in particular to an EIP classification method and system based on service types.

Background

With the rapid development of cloud computing, many enterprise data are migrated to the most basic cloud computing cloud server, and with the encouragement of cloud policies of government departments to the enterprises, the cloud of the enterprises has a great tendency, and the cloud server cancels hardware cost for the enterprises, reduces operation and maintenance cost of the enterprises, has strong expansibility and extensibility, and is just the reason that the enterprises cloud the dispute.

By purchasing a cloud server (ECS), a user avoids the early preparation of purchasing IT hardware, and the user can conveniently and efficiently use the server as common resources such as water, electricity, natural gas and the like, so that the computing resources can be opened and used and elastically stretched.

An Elastic IP Address (EIP) is a public IP Address resource that can be purchased and held independently. The EIP may be bound to gateways for ECS instances, private network SLB instances, and NAT instances of the proprietary network type. The EIP is an NAT IP which is actually positioned on a public gateway, is mapped to the bound resources in an NAT mode, and can be communicated with the public network through the EIP after being bound with the cloud resources.

The working schematic diagram of the EIP in the prior art is shown in fig. 1, and the EIP is used as a NAT IP to configure SNAT and DNAT rules. DNAT rule: the external request destination address is the data of the port 2, and the destination address is converted into a VM address; SNAT rule: the VM sends a request to the public network to change the source address to the address of port 2. Floating point IP is set on external gateway port 2.

At present, most public cloud manufacturers are realized based on openstack, network components neutron in openstack do not classify EIP when EIP is realized, such as telecom EIP, Unicom EIP, BGP EIP and the like, all use BGP mode, and the mode increases operation cost for customers only using EIP of certain operator.

Disclosure of Invention

In view of the above, an object of the present invention is to provide an EIP classification method and a classification system based on service types, which are used to solve the problems that the EIP is not classified and the operation cost is high in the prior art.

In order to achieve the above object, the present invention provides an EIP classification method based on service types, comprising the steps of:

establishing a subnet in a public network IP pool, and distributing the subnet according to an operator;

according to an operator, a user applies for an appointed EIP type;

neutron assigns EIP to the user in the responding subnet upon user request.

Optionally, the parameter attribute values of the API interface of Neutron are extended.

Optionally, when creating the subnet in the public network pool, the parameter for creating the subnet API interface is multiplexed, and the parameter attribute value is extended to indicate the operator information to which the subnet belongs.

Optionally, when creating the EIP, an extended parameter of the floating IP is used, and an attribute value of the extended parameter is modified to indicate the EIP of the desired operator.

The invention also provides an EIP classification system based on service types, which comprises:

the control node receives the EIP type requested by the user, creates the EIP and processes the service logic;

the network node sets a corresponding EIP according to the EIP established by the control node, so as to be used for three-layer intercommunication and outer network communication of a bearing tenant network;

and the computer node is used for creating a cloud server and providing the cloud server for a user, and the user is communicated with the external network through the EIP set by the network node.

Optionally, the user creates an EIP on the Web page and binds the host; and the Dashboard at the front end of the control node sends the user request to the Neutron server, and the Neutron server creates a corresponding EIP according to the user request.

Optionally, the network node configures a corresponding EIP at an external gateway on the virtual router according to the user request.

Optionally, the user creates a virtual server and communicates with the extranet through EIP binding to the host

Compared with the prior art, the technical scheme of the invention has the following advantages:

the invention expands the operator attribute of the EIP and subdivides the EIP into different types. BGP types of EIP are more costly and single line EIP is less costly. After the EIP is subdivided according to the operators, users without BGP can apply for the EIP with the required type according to the requirements, and the cost of the users is effectively reduced.

The invention increases the attribute information of EIP and provides better compatibility on the basis of not changing the original interface of neutron. When the cloud manufacturer docks the neutron, the interface of the cloud manufacturer does not need to be modified, and the development difficulty is effectively reduced.
