C: the request for allocation of Node Controller resource response pool manager in the resource node networking, control specify serial ports in place;
D: the result that resource pool manager returns according to the respective nodes controller, set up serial ports I/O map of services with the front end virtual desktop.
Preferably, also comprise step a1 before the step a: with the serial ports integrated terminal is resource node, sets up the resource node networking.
Preferably, between step a1 and step a, also comprise: each node in the networking of resource pool manager scanning resource node, initialization serial port resource pond.
Preferably, also comprise step e after the steps d: the front end virtual desktop finishes the use of serial port resource, and resource pool manager discharges corresponding serial port resource, and serial ports is turned back to idle condition.
Preferably, step e specifically comprises:
A1: the front end virtual desktop sends and finishes serial port resource is used request;
A2: resource pool manager control respective resources node discharges specifies serial port resource;
A3: Node Controller resource response pool manager request, remove the duty of specifying serial port resource, make its free time;
A4: the resource pool server discharges corresponding serial ports I/O service, and refreshes current serial port resource pool state.
A kind of serial port distributed resource management system comprises: serial port resource pool, said serial port resource pool are set up with the front end virtual desktop through hub and are communicated by letter;
Said serial port resource pool comprises resource pool server, resource node networking, and the resource pool server connects through hub and resource node networking.
Preferably, said resource node networking comprises serial ports integrated terminal, Node Controller, is used for serial port resource on management and the Control Node, and intercoms mutually with Resource Server.
Preferably, said resource pool server comprises resource pool manager, be used for management resource node networking serial port resource and distribute, and the I/O map of services of foundation and front end virtual desktop.
The present invention compared with prior art has the following advantages:
A, raising peripheral hardware use dirigibility
Make up the serial port resource pool in the rear end, the communication port resource is provided, broken through restriction end to end, improved the dirigibility that peripheral hardware uses to virtual desktop.
B, alleviation terminal pressure
The adding of serial port resource pool makes a part of port I/O service to detach out from the terminal, and the terminal only need provide individual dependence stronger serial port service, and other port I/O service can have the serial port resource pond that is positioned at the rear end to provide fully.
The centralized management of c, realization device resource
The serial port resource pool exists with the logical form of an integral body in the rear end, easily realizes the centralized management and the load balance of port resource.
