Patent GB-2590448-A (GB)
Title: A controller, computer program and method
Inventor: RICHARD COOPER
IPC: H04L45/24
Filed: 2019-12-18
Abstract: A method for a controller 300 to manage a network in a production environment such as a media broadcast studio, the network also comprising spine switches 102, leaf switches 104, a studio facilities management system (SFMS) 600 and endpoints 106 such as cameras and monitors. The controller identifies the endpoints to be used on the network during a time period, and at a predetermined time prior to this period runs a flow routing algorithm (FRA) for the network having the identified endpoints. Endpoints to be added to the network during the time period may be based on a type of programme being produced in a studio or the identity of a programme producer. The time period may be partitioned into sections during which routes will not be rearranged and may be obtained from schedules or bookings known by the SFMS. The FRA may be a deterministic algorithm such as Dijkstra’s algorithm, a simulation technique or a brute-force search. The advantage of the invention is that it may be used to predict route flows in advance and avoid route changes which could cause disruption of services such as a live video broadcast.

The radial width and/or axial width of the pumping channel, which may be helical (fig.2) or spiral, can increase towards the outlet as too can the size of the liquid opening and hence the volume of the liquid blade. The liquid opening may be a slit which is arranged as a helix around the rotor, or it may be formed of multiple smaller openings in a line. The pump can have a seal (32, fig.5) and be used as a vacuum pump that compresses the gas by having a decreasing cross-section of available space in the pumping channel even when the channel increases in cross-section.
