TermDescription
CRUDIn computer programming, create, read, update, and delete (CRUD) functions are the basic functions of persistent storage.entityAny piece of hardware or software that wants to connect to the network services provided by Quantum. An entity can use Quantum network services by implementing a VIF.IPAMInternet Protocol Address Management (IPAM) is a means of planning, tracking, and managing the Internet Protocol (IP) address space that is used in a network.layer-2 networkA virtual Ethernet network that is managed by the Quantum service. Currently, Quantum manages only Ethernet networks.networkAn isolated virtual layer-2 broadcast domain that is typically reserved for the tenant who created it unless the network is configured to be shared. Tenants can create multiple networks until they reach the thresholds specified by per-tenant quotas.pluginA software component that implements Quantum API v2.0.portA virtual switch port on a logical network switch. Virtual instances attach their interfaces into ports. The logical port also defines the MAC address and the IP addresses to be assigned to the interfaces plugged into them. When IP addresses are associated to a port, this also implies the port is associated with a subnet, as the IP address was taken from the allocation pool for a specific subnet.subnetAn IP address block that can be used to assign IP addresses to virtual instances. Each subnet must have a CIDR and must be associated with a network. IPs can be either selected from the whole subnet CIDR or from allocation pools that can be specified by the user.VMA virtual machine (VM) is a completely isolated guest operating system installation within a normal host operating system.http://docs.openstack.org/api/openstack-network/2.0/content/Glossary.htmlroute add 192.168.2.0 mask 255.255.255.0 10.1.0.254 -p

uantum数据库中的routers表数据是怎么产生的?
你要在quantum里面创建router
quantum router-create , 然后创建的router会保存在这个表里面
quantum router-create , 然后创建的router会保存在这个表里面
routers里面的数据是quantum的虚拟路由器。
gre和vlan的区别主要在于,网络的隔离和转发方式,gre相对更适合大型公云,vlan比较私云和小型公云。

subnet里的host_routes是同一个network下的不同subnet之间的主机路由吗?ports里面的device_id\device_owner分别代表什么,数据来源是哪里?
device_id就是vswitch设备的id
, owner是port所对应的对象, 例如, 虚拟机, router或者gateway神马的
比如qrxxxxxx, tapxxxxxx
dhcpXXXX 那个是linux的ip namespace
新建一个网络, 就会有个新的namespace

L2 agent就是openvswitch agent
