The data service module of business layer, wherein B11, B21, B31 are main data service module, remaining is standby data service module；
With reference to Fig. 2, data service module (B11, B2) is called in AM access module (A1), there is distribution IP address, inquiry IP address
The functions such as binding state, more new IP address lease and release IP address lease；Data service (B11, B2) calls storage service
(C), there are the functions such as inquiry IP address pond configuration, IP address lease data persistence；
The DHCP cluster of this programme is made of multi-group data service module group, and every group active and standby each other, every group of bearing part IP
The distribution and lease management of address pool；
Every group of data service module group has active and standby two services (or main prepare more, but in view of data replicate bring net
Network flow pressure, standby using one main one in actual production)；
Active and standby data service module keeps IP address pond synchronous with IP address lease；
After primary service exception, active service changes into primary service, after former primary service recovery is normal, into spare shape
State；
When data service module abnormal restarting, from storage service load IP address pond configuration, IP address state and lease number
According to, receive primary service synchrodata (from storage service load data during, while load while synchronize, it is newer with the time
IP address state, lease data replace expired data), reach Fast synchronization (be different from from primary service grab full dose IP
Address state and lease data, the method for synchronization of the invention can mitigate the load of primary service)；
The data service of difference group carries the different distribution of IP address pond and lease management；
Every group of data service all caches the IP address pond configuration of full dose, inquires any one available data service and is ok
Obtain the relevant configuration information in a certain IP address pond.
The technical program access layer flattening, load balancing, the DHCP request of load bearing equipment, AM access module are independent of each other,
Mutually independent, any one data service module is abnormal, will not influence the operation of other data service modules；As portfolio increases
Greatly, load excessive, can increase the quantity of AM access module with load sharing, data service layer guarantee data it is reliable with it is consistent
Property, guarantee the uniqueness of IP address distribution；Accumulation layer guarantees the safety of the configuration of IP address pond, IP address state and lease data
Property；After data service exception, the configuration of IP address pond, IP address state and IP address lease data can normally, be quickly loaded；It should
DHCP trunking mode is able to achieve the DHCP service of large capacity, high throughput, High Availabitity.
Embodiment one
Further, it is equipped with and is connected with each other between the AM access module and master data service module and standby data service module
Event interface and message interface, the event interface between access service and data service service state notice and the heart
Jump notice.
With reference to Fig. 3, event interface (a), the service state between AM access module (A1) and data service module (B11, B12)
Notice and heartbeat notification, event interface (a) use connectionless UDP communication mode；
Message interface (b), AM access module (A1) to the calling service of data service module (B11, B12), as: inquiry IP
The configuration of location pond obtains IP address, inquires IP address binding state, renews the lease, AM access module is only to current primary data

Embodiment three
Further, the primary service module is for keeping IP address pond synchronous with IP address lease；The standby data clothes
Module of being engaged in is used for when master data service module exception, and standby data service module switchs to primary data service, former master data service
After module recovery is normal, into stand-by state.
Example IV
Further, the data service module group is equipped with more than one set, and every group of data service module group carries different
The IP address pond configuration of the grouping of IP address pond, IP address segmentation and full dose；
The grouping of IP address pond,
DHCP cluster of the invention is made of multi-group data service module group, the different IP address pond distribution of every group of carrying,
For the IP address pond of different routes or DHCP Relay, it would be desirable to which suitable rule is grouped:
Multiple IP address ponds of same route are not as far as possible in the same service group；
Multiple IP address ponds of same DHCPRelay are not as far as possible in the same data service group；
One IP address pond available address is divided into two sections or multistage, is distributed in different data service groups；
The grouping of IP address pond can guarantee that IP address of equipment distributes reliability, this needs IP address configured with certain redundancy.
The grouping in the IP address pond of same route or DHCP Relay is more, and IP distribution reliability is higher, but time of DHCP service retrieval
Number is more, and system pressure is bigger, this needs is suitably grouped in configuration of IP address pool.
The number according to data group is needed in configuration of IP address pool, by the IP of same route or same DHCP Relay
Location pond is distributed in different data service groups.
The configuration of IP address pond,
The configuration of IP address pond includes DHCP-Relay configuration, subnet configuration, line configuring, Option configuration, IP address pond
Grouping information etc.；
The IP address pond configuration data of each data service caching full dose, inquires any one available data service all
The relevant information in available a certain IP address pond.
The segmentation of IP address pond,
When a certain route or DHCP Relay only configure an IP address pond, as needed one using biggish B class address
A IP address pond is divided into two sections or multistage (usual two sections or three sections) by available address, is distributed in different data service groups,
When active and standby two services for having a grouping are all abnormal, it can guarantee that an IP address pond at least part IP address can divide
Match；
Such as: IP address pond: 10.16.0.0/24, gateway address: for 10.16.0.1；
IP address can be used are as follows: 10.16.0.2-10.16.0.254；
IP address pond is divided into two sections: 10.16.0.2-10.16.0.128,10.16.0.129-10.16.0.254；
If the data service of 10.16.0.2-10.16.0.128 is abnormal, 10.16.0.129- can also be distributed
10.16.0.254 address.
