Abstract: Methods and apparatus for interfaces to manage virtual network interface objects. A system may include resource instances and a network interface virtualization coordinator. Responsive to a record creation request, the coordinator creates an interface records that may include an IP address, subnet information and security properties. The coordinator may, in response to a request to attach the record to a resource instance, enable traffic directed to the IP address to flow to the resource instance. In response to a subsequent detach request, the traffic to the IP address may be disabled at the resource instance. The same interface record may be attached to another resource instance in response to another attach request, enabling traffic directed to the IP address to flow to the second resource instance.

Abstract: A request is received to change an association of a network interface record from a first resource instance to a second resource instance. The network interface record may include an IP address associated with the first resource instance. In response to the request, the first resource instance is prevented from receiving data packets addressed to the IP address of the network interface record through a first network interface object attached to the first resource instance. The network interface record is associated with the second resource instance so that the second resource instance is enabled to receive data packets addressed to the IP address of the network interface record through a second network interface object attached to the second resource instance.

Abstract translation: 接收到将网络接口记录从第一资源实例到第二资源实例的关联改变的请求。 网络接口记录可以包括与第一资源实例相关联的IP地址。 响应于该请求，防止第一资源实例通过附加到第一资源实例的第一网络接口对象来接收寻址到网络接口记录的IP地址的数据分组。 网络接口记录与第二资源实例相关联，使得第二资源实例能够通过附加到第二资源实例的第二网络接口对象来接收寻址到网络接口记录的IP地址的数据分组。
