Description
Technical field
The present invention relates to load-balancing technique field, the IPv4 terminal specially based on virtual IP address v4 address pool, IPv6 clothes
Business interworking service SiteServer LBS.
Background technology
In recent years, the Internet is in the transition period migrating from IPv4 to IPv6, within this transition period, there is IPv4
Terminal access IPv6 resource and the demand of IPv6 terminal access IPv4 resource.In this filtration later stage, IPv4 terminal access
IPv6 service will become main flow.The mechanism that the NAT64 having state is bound by NAT64 static address, is that IPv4 terminal use carries
For accessing the ability of IPv6 content (IPv4/IPv6 interworking service).
Usually, separate unit NAT64 equipment can meet the need of the interworking service application that above-mentioned IPv4 terminal services to IPv6
Ask, but under operator scenario, in the case that user's connection request many datas transmission quantity is big, separate unit NAT64 equipment will become
For the bottleneck of service, in the case of overload, may result in operation slow even cannot normal service, so needing negative
Carry balancing technique and overcome above problem.
Scene for above-mentioned IPv4 terminal access IPv6 service, it is possible to use traditional SiteServer LBS, such as LVS,
IPv4 address and IPv6 address are carried out with load balancing, multiple stage NAT64 conversion equipment provides address translation service, their equipment are joined
Put different IPv4 address pool, these address pool are separate, do not intersect, do not repeat, the message of each IPv4 address corresponding is only
Processed by a wherein equipment.
The shortcoming of prior art：There is problems with such SiteServer LBS：Different NAT64 device configurations are different
IPv4 address pool, and address pool is separate, when, in certain device fails, this address pond is changed into invalid, causes address
The waste in pond；Access in the flow process of IPv6 service in IPv4 client, due to needing the address in binding IP v4 address pool and end
Mouthful, when this device fails, this IPv6 service will be unable to access, and causes Single Point of Faliure.This is to require in network reliability
In, very fatal pain spot.
Content of the invention
It is an object of the invention to provide IPv4 terminal based on virtual IP address v4 address pool, IPv6 service-interworking business load
Equalizing system, to solve the problems, such as to propose in above-mentioned background technology.
For achieving the above object, the present invention provides following technical scheme：IPv4 terminal based on virtual IP address v4 address pool,
IPv6 service-interworking traffic load balance system, including IPv4 terminal, IPv6 server, switch and multiple cluster service
Device, described IPv4 terminal access to IPv 4 network, described IPv6 server accesses IPv6 network, described IPv4 network and described IPv6
Network is respectively connected to switch, and described switch connects multiple cluster servers.
Preferably, the plurality of cluster server includes the first cluster server, the second cluster server, the 3rd cluster clothes
Business device, N cluster server, N is the integer more than 3, and multiple cluster servers are completely the same, all includes common IPv6 address
Pond, common virtual IP address v4 address, common address static binding information.
Preferably, its using method comprises the following steps：
A, IPv4 terminal sends message from the address port of itself to the corresponding IPv4 address port of IPv6 service, and message arrives
After reaching switch, it is transmitted to certain cluster server having taken over this virtual ip address；
B, this cluster server calculate and breathe out according to the source IP address of message and mesh ground IP address general concordance hashing algorithm
Uncommon value, and find corresponding link information in the network interface link information of whole cluster, if link-local, then by this
Ground server process, if neighbours' link, is then transmitted to this neighbor node；
C, the node of actual treatment, the IPv6 address pool according to configuration and NAT64 address binding information carry out IPv4/IPv6
Address conversion, IPv4 report is converted into IPv6 message, and is forwarded to IPv6 server；
The response of D, IPv6 server is then forwarded directly to just carry out the cluster server of IPv4/IPv6 address conversion, by
In purpose IPv6 address Match IP v6 address and consistent with static address binding table, IPv6 message is converted into IPv4 message, and turns
Issue IPv4 terminal.
Compared with prior art, the invention has the beneficial effects as follows：The present invention is capable of the reasonable utilization of IPv4 address pool,
Avoid IPv4 terminal/IPv6 service-interworking traffic failure that Single Point of Faliure causes, and make full use of IPv4 address pool, it is to avoid be limited
IPv4 address waste.

Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative work
Embodiment, broadly falls into the scope of protection of the invention.
Refer to Fig. 1-4, the present invention provides a kind of technical scheme：IPv4 terminal based on virtual IP address v4 address pool, IPv6
Service-interworking traffic load balance system, including IPv4 terminal 1, IPv6 server 2, switch 3 and multiple cluster server,
Described IPv4 terminal 1 accesses IPv4 network 4, and described IPv6 server 2 accesses IPv6 network 5, described IPv4 network 4 and described
IPv6 network 5 is respectively connected to switch 3, and described switch 3 connects multiple cluster servers；Multiple cluster servers include first
Cluster server 6, the second cluster server 7, the 3rd cluster server 8, N cluster server, N is the integer more than 3, multiple
Cluster server is completely the same, all includes common IPv6 address pool, common virtual IP address v4 address, common address static state are tied up
Determine information, access the address binding of IPv6 content for IPv4.
The using method of the present invention comprises the following steps：
A, IPv4 terminal sends message from the address port of itself to the corresponding IPv4 address port of IPv6 service, and message arrives
After reaching switch, it is transmitted to certain cluster server having taken over this virtual ip address；

Address conversion, IPv4 report is converted into IPv6 message, and is forwarded to IPv6 server；
The response of D, IPv6 server is then forwarded directly to just carry out the cluster server of IPv4/IPv6 address conversion, by
In purpose IPv6 address Match IP v6 address and consistent with static address binding table, IPv6 message is converted into IPv4 message, and turns
Issue IPv4 terminal.
Cluster self-organizing in the present invention and maintenance process：
By the change triggers of intervalometer and network interface state, realized by IPv4/IPv6 multicast mode in cluster.Collection
Group broadcasts interactive information and includes, network interface link information and virtual IP address election information.When the steady-state is achieved, each
Virtual ip address both corresponds to some network interface link of certain equipment, and virtual IP address v4 address balancedly distribute each in cluster
On equipment, after election completes, switch also to be responded is inquired about for the ARP of virtual IP address.When certain equipment fault, one
Miscellaneous equipment in interior cluster of fixing time clears up this node automatically, reselects distribution virtual ip address, reaches steady statue.Mainly
Handling process as shown in Figure 2 and Figure 3.
The present invention is capable of the reasonable utilization of IPv4 address pool, it is to avoid the IPv4 terminal that Single Point of Faliure causes/IPv6 clothes
Business interworking service fault, and make full use of IPv4 address pool, it is to avoid limited IPv4 address wastes.
