Abstract: Technology is described for migrating connections for Internet of Things (IoT) devices. Data packets may be received from an IoT device for forwarding to a first physical host in a computing service environment. A determination to migrate the connection for the IoT device from the first physical host to a second physical host in the computing service environment may be performed when a throughput of the data packets received from the IoT device for the first physical host exceeds a defined threshold. A connection migration procedure may be initiated to migrate the connection for the IoT device from the first physical host to the second physical host. The connection migration procedure may include an exchange of session state information for the IoT device from the first physical host to the second physical host to enable the migration of the connection to the second physical host.

Abstract: The data transmission rate (DTR) of a data devices (12) connected to a data transmission service is controlled to be within an authorized collective DTR for the data devices, such as the authorized total DTR for a customer. The data devices transfer data to and/or from a data storage system (20) through front end hosts (16). The front end hosts send messages to a controller (22A) reporting the amount of data transferred and the data devices responsible for the data transfer. The controller determines whether the data devices are exceeding the authorized collective DTR and, if so, directs the front end hosts to increase the latency or delay before a front end host acknowledges receipt of data from the data devices and/or to decrease the buffer size in the front end host with respect to those data devices. This brings the DTR within the authorized collective DTR.
