Problems solved by technology

However, for the large-capacity, high-throughput, and high-reliability DHCP service requirements of the carrier class, multiple DHCP servers are required to carry services. If each DHCP service independently carries part of the allocation of IP address pools, it is not conducive to the planning of IP address pools. and configuration management, insufficient disaster recovery capability
Unable to meet the performance requirements and security requirements of carrier-class IP address allocation

Embodiment 1

[0071] Further, an event interface and a message interface connected to each other are provided between the access module and the main data service module and the backup data service module, and the event interface is used for service status notification and notification between the access service and the data service. Heartbeat notification.

[0072] refer to image 3 , the event interface (a), the service status notification and heartbeat notification between the access module (A1) and the data service module (B11, B12), the event interface (a) adopts a connectionless UDP communication method;

[0073] Message interface (b), service call from access module (A1) to data service module (B11, B12), such as: query IP address pool configuration, obtain IP address, query IP address binding status, update lease, etc., access The module only sends requests to the current primary data service, and the message interface (b) uses TCP communication.

Embodiment 2

[0075] Further, an event interface, a message interface and a synchronization interface connected to each other are set between the primary data service module and the standby data service module;

[0076] The event interface (a) is used for service status notification between the primary data service module and the standby data service module, synchronization event status synchronization, primary and secondary election events, and heartbeat notification; the event interface uses a connectionless UDP communication method;

[0077] The message interface (b) is used for the standby data service module to forward the request from the access service; the message interface adopts the TCP communication mode;

[0078] The synchronization interface (c) is used for IP state synchronization and IP lease synchronization between the primary data service module and the standby data service module; the synchronization interface adopts TCP communication mode.

Embodiment 3

[0080] Further, the main service module is used to keep the IP address pool and the IP address lease synchronous; the backup data service module is used to switch the backup data service module to the active data service when the main data service module is abnormal, and the original main data service module After returning to normal, enter the standby state.

Abstract

The invention provides a DHCP (Dynamic Host Configuration Protocol) service cluster and a construction method. The method is characterized in that a flat access layer is established, an access load ofthe access layer is shared, a DHCP request of a bearing device and access modules are not mutually influenced and independent, any one data service module is abnormal, and the operation of other dataservice modules is not influenced; The data service layer guarantees reliability and consistency of data and guarantees uniqueness of IP address distribution; The data service layer consists of a plurality of groups of data service module groups, each group is mutually used as a master and a standby, and each group bears distribution and lease management of partial IP address pools; The storage layer ensures the safety of IP address pool configuration, IP address state and lease data, and after the data service is abnormal, the IP address pool configuration, the IP address state and the IP address lease data can be normally and quickly loaded; According to the DHCP cluster mode, the DHCP service with high capacity, high flux and high availability can be realized.

Description

technical field [0001] The invention relates to a DHCP service cluster and a construction method, in particular to a DHCP service cluster and a construction method that can meet the performance requirements and security requirements of telecom-level IP address allocation. Background technique [0002] The DHCP service is mainly to realize the requirement of dynamic allocation of IP addresses of multiple terminals, and at the same time ensure that the IP address assigned to each device is unique. For a small number of IP address pools, generally a single or two master and slave DHCP servers are used for implementation. However, for the large-capacity, high-throughput, and high-reliability DHCP service requirements of the carrier class, multiple DHCP servers are required to carry services. If each DHCP service independently carries part of the allocation of IP address pools, it is not conducive to the planning of IP address pools. And configuration management, disaster recove...
