the management node is adapted to create a distributed virtual switch on the plurality of computing nodes and to start a DHCP service module and a DHCP management service module on each computing node based on the distributed virtual switch; the DHCP service module and the DHCP management service module are used for providing DHCP service for a virtual machine borne by the computing node;
the management node is also used for analyzing whether the DHCP service information generated by the DHCP service module on each computing node to the virtual machine is available or not according to the DHCP service information of the computing nodes, and feeding back the analysis result to the DHCP management service module on the corresponding computing node;
the DHCP service information comprises a static network protocol IP address, acquisition time and a DHCP lease;
the analyzing whether the DHCP service information generated by the DHCP service module on each computing node to the virtual machine is available comprises:
and analyzing whether the corresponding IP address is available according to the acquisition time.
8. The system according to claim 7, wherein any of said computing nodes is adapted to respond to a DHCP service request issued by a virtual machine through said DHCP service module; determining DHCP service information provided for the virtual machine through the DHCP service module according to the DHCP service request, and reporting the DHCP service information to the management node through the DHCP management service module; and receiving the analysis result of the management node on the DHCP service information through the DHCP management service module.
9. A computer-readable medium, in which an implementation program of a dynamic host configuration protocol is stored, which, when executed by a processor, implements the steps of the implementation method according to any one of claims 1 to 6.
