Embodiment Construction

[0020] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] figure 1 A block diagram showing a cloud computing multi-tenant-oriented distributed virtual DHCP service providing system according to an embodiment of the present invention, as figure 1 As shown, the system generally includes: multiple tenants, each tenant corresponds to one or more virtual machines adapted to their respective virtual networks, the multiple virtual machines are connected to a virtual switch, and each virtual network corresponds to A namespace, each namespace starts a dnsmasq process responsible for providing DHCP services.

[0022] Among them, such as figure 1 As shown in the figure, two hosts are shown in the figure, and each host has two tena...

Abstract

The invention provides a distributed virtual dynamic host configuration protocol (DHCP) service providing system comprising one or more lessees, wherein each lessee is corresponding to one or more virtual machines fit with respective virtual networks, the virtual machines are connected with a virtual switch, each virtual network is corresponding to a namespace via the virtual switch, and each namespace starts a dnsmasq progress to be responsible for providing a DHCP service. The system provided by the invention can avoid the waste of address resources and meanwhile can achieve the separation of DHCP traffic, and supports multi-user operation.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a cloud computing multi-tenant-oriented distributed virtual DHCP service providing system and method. Background technique [0002] Dynamic Host Configuration Protocol (DHCP) is usually applied in large-scale local area network environment, and its main function is to centrally manage and allocate IP addresses, so that hosts in the network environment can dynamically obtain IP addresses, Gateway addresses and DNS server addresses and other information, and increase the utilization rate of addresses. [0003] The DHCP protocol adopts the client / server model, and the dynamic allocation task of the host address is driven by the network host. When the DHCP server receives the information from the network host to apply for an address, it will send relevant address configuration and other information to the network host to realize the dynamic configuration of th...
