The virtual interface at place；Message queue, the amount of bandwidth that setting dhcp message communicates, it is ensured that DHCP disappears are established on virtual interface
The quality of message communication.
Two or more DHCP Server are grouped DHCP by the Remote configuration DHCP Agent service support
Server Group supports more than one DHCP Agent to send identical message, guarantees the reliability of DHCP service；
The record of Remote configuration operation task is established, convenient for tracking operating result；
The message content includes port information, the son to be bound of DHCP Server Group id, DHCP Sever
The network information (address mac, the address ip, Hostname) of net information and associated virtual machine；Port information includes interface name
Claim, IP address, subnet information includes subnet network segment, gateway address, the address network information mac, the address ip, Hostname.
The Remote configuration DHCP Qos Agent service includes:
(1) customized DHCP Qos Agent Reset API service is provided, defined in content include DHCP
The amount of bandwidth relationship of the ID of Server Group, the size information of bandwidth or global default；
(2) by transmitting the message to affiliated net for above relationship and the virtual machine port information bound combination
On DHCP Qos Agent where the virtual machine of card；
(3) record of Remote configuration operation task is established, convenient for tracking operating result.
The present invention program's has the beneficial effect that:
1, the system of software definition DHCP service is provided, Rest API is externally provided, it is convenient convenient for open and integrated service
Management.
2, the elasticity capacity and reliability of cloud computing DHCP service are improved, while ensureing the bandwidth requirement of DHCP data.
Detailed description of the invention
The following further describes the present invention with reference to the drawings:
Fig. 1 is module map of the invention.
Specific embodiment
As shown in Figure 1, system structure of the invention is as follows:
(1) controller operates, and the Rest API of creation operation described in detail below is described to be illustrated with message communicating:
A) the Rest API of DHCP Server Group group is established to the local area network of user
POST operation:
Required parameter: network subnet information
Feedback: DHCP Server Group id
Specific implementation distribution DHCP Server Group, is associated with 2 or more for DHCP Sever Group id
In DHCP Agent, and information is persisted in database, and by network subnet message and DHCP Server Group information
It is sent in DHCP Agent, and records operation log.
Wherein network subnet message includes subnet mask, gateway, name server etc.
DHCP Server Group information includes the IP address of DHCP process needs, Group id, needs to be tied to DHCP
IP, mac address information on Server etc..
B) network information of associated virtual machine is provided to the Rest API in DHCP Server Group
Post operation:
Required parameter: the network information of virtual machine, DHCP Server Group id
Specific implementation description:
Will virtual machine network message and DHCP Server Group id relation perdurability into database, obtain
The associated DHCP Agent of DHCP Server Group id, network subnet message and DHCP Server Group information are sent
Into DHCP Agent, and record operation log.
C) the DHCP Qos Rest API of the port of associated virtual machine is provided
Post operation: creation DHCP Qos information
Required parameter: DHCP Sever Group id, DHCP Qos amount of bandwidth
It specifically describes: Group id being associated with Qos size and persistence, acquisition and DHCP Server Group id are closed
DHCP Qos Agent where the virtual machine port of connection, is sent to DHCP for DHCP qos amount of bandwidth and port information
On Qos Agent, and record operation log.
(2) DHCP Qos Agent is serviced
Actual DHCP Server Group is established according to DHCP Server Group id:
It supports to execute in the system of NameSpace at linux:
ip netns add$dhcp_group_id
The virtual interface $ dhcp_server_ of DHCP Server binding is established on $ dhcp_group_id NameSpace
interface
Dhcp.conf configuration file is established at/var/lib/dhcp/ $ dhcp_group_id, configuration file content is such as
Under:
Fa:16:3e:c1:60:57, host-10-0-16-1.gcloudlocal, 10.0.16.1
Others.config file is established at/var/lib/dhcp/ dhcp_group_id, describes domain name and gateway
Information configuration file is as follows:
Tag:tag0, option:dns-server, 202.96.128.86,8.8.8.8
Tag:tag0, option:router, 10.0.16.
Start DHCP Server process on $ dhcp_group_id NameSpace, as follows:
ip netns exec$dhcp_group_id dnsmasq--no-hosts--no-resolv--strict-
Order--bind-interfaces--interface=$ dhcp_serverinterface--except-interface=
Lo--pid-file=/var/lib/dhcp/ $ dhcp_group_id/pid--dhcp-hostsfile=/var/lib//
Dhcp/ $ dhcp_group_id/dhcp.conf--dhcp-optsfile=/var/lib//dhcp/ $ dhcp_group_id/
Others.config--leasefile-ro--dhcp-range=set:tag0, $ subnet static, infinite--
Dhcp-lease-max=256--conf-file=/etc/neutron/dnsmasq-neutr on.conf--domain=
gcloudlocal
Wherein $ subnet is subnet network segment, such as 10.0.0.0.
(3)DHCP Qos Agent
The DHCP Qos message of controller is obtained, message is described below:
{ vm_port_id:$ vm_port_id, dhcp_qos:$ dhcp_qos_value, other_qos:$ other_
qos_value}
According to message above, two message queues are established on the network port of virtual machine, wherein first message queue
Bandwidth be $ dhcp_qos_value, the bandwidth of second message queue is $ other_qos_value, and specific implementation can pass through
The tc tool of linux realizes that, by the Packet Filtering of 67 or 68 ports to first message queue, other message packets are filled into
Second message queue.
Above disclosed is only the one of embodiment of the present invention, cannot limit the power of the present invention with this certainly
Sharp range, therefore equivalent changes made in accordance with the claims of the present invention, are still within the scope of the present invention.
