In order to prepare for a possible transition, data flow is monitored between the two portions of the application, each portion interacting with a different hardware entity. The data flow between the first portion and the second portion of the application is recorded. If the second hardware entity is not available at the time, the recorded data flow from the first portion may be replayed by the second portion of the application for the benefit of the second hardware entity. If the second portion of the application is to be reassigned to another hardware entity, the target hardware entity may be sent the second portion of the application, as well as the recorded information.

The invention discloses a method of controlling a flow bandwidth. For one data flow set, under the condition that the data flow set uses a historical adjusting strategy and a predefined strategy to distribute labels in a historic time period, a flow state satisfies an expected degree and a machine learning model is trained, and the machine learning model acquired through training determines a current adjusting strategy which makes a subsequent flow state of the data flow satisfies an expectation maximumly according to a flow statistics result of the data flow set in a current time period. Therefore, network equipment can adjust a strategy which is predefined by a user according to the changed flow state so that labels distributed for a key service are increased and/or labels distributed for a non-key service are decreased. A sending speed of a non-key service flow is reduced so that a link bandwidth is not occupied excessively by the non-key service flow and a data flow of the key service can occupy an enough bandwidth at an entrance and an exit of network equipment.

Descriptions can describe or contain document contents and layout. Some contents can be images and, instead of being included as image data in the description, can be image references. An image reference can be used to obtain an image, in the form of image data, from an image server. A printer can print the document after obtaining needed images from image servers. The image data often contains an image whose resolution does not match the resolution that the printer can properly print in the document. The image server can prepare image data with the correct resolution or can stream image data through a data connection to the printer in a hierarchical image format. A printer can receive a stream of hierarchically formatted image data until a desired resolution is reached and then simply close the data connection to cut off the stream of image data.
