Abstract
The invention discloses a network flow load balancing method. A group of IP addresses is analyzed from a domain name, each IP address is edited into a routing group, each group contains two or more server devices, however one server device serves as a master device and the other devices serve as slave devices at the same time; and meanwhile, one server device is distributed in different IP address groups, no new load balancing device needs to be increased, a load balancing function is completely achieved by the routing function of a switch, in a certain IP address group, and when the master device is faulty, the slave device is automatically switched according to different priorities of routing protocols, thereby ensuring the continuity of services. Since a master-slave protocol is employed, abnormal jitter of the entire IP address will not happen, in the case of faults, the restoration time is very short and is about 1 second due to the routing protocol level.

When accessing the Internet, by dispatching technique, the access request of user is dispatched in the optimum CDN node of service quality.In CDN
Intra-node, is typically first accessed domain name, is obtained the IP address of service by dns agreement, then go to access by IP address real
Service.Service scale progressively expands at any time, and access request also gets more and more, and now can form server set using one group of server
Group, externally provides service in the lump by server cluster.Now, the entrance that user accesses is still domain name, by dns protocol analysis
Go out the IP address of this cluster.
Have several as follows at present in the common analysis mode of CDN node：
1. parse an IP address, this IP address falls on single load-balancing device, set by load balancing
The standby scheduling carrying out cluster internal.
● advantage is when wherein a certain server fail, can automatically weed out in cluster internal, and fault takes
Business device rejected the time in 1 second, was not very big on overall quality of service impact.
Shortcoming is to need to increase extra load-balancing device, and this undoubtedly increased O＆M cost.
2. parse one group of IP address, an equipment in the corresponding cluster of each IP address.
● advantage is not need extra load balancing machine, will not increase extra cost.
Shortcoming is that the recovery of failed server depends on dns to parse, and the time that server failure recovers is generally at 1 point
More than clock, the local dns of especially part province operator does not follow agreement.
3. parse an IP address, this IP address is assigned to multiple devices through switch ecmp agreement equal-cost route
On.
● advantage is not need extra load balancing machine, will not increase extra cost, and failure recovery time was at 1 second
Within.
Shortcoming is when failed server is recovered, and is limited to ecmp protocol convergence it may occur that whole cluster the whole network is shaken
Phenomenon.
Content of the invention

When convergence and shake.
For achieving the above object, the present invention provides following technical scheme：
A kind of network traffic load method in a balanced way, translates domain names into out one group of IP address, and each IP address is compiled as
One group of routes, comprises 2 and with last server apparatus in each group, but only has one as main equipment simultaneously, other
Equipment is as from equipment；Meanwhile, server apparatus are distributed in different IP address groups, when working properly, IP address
It is resolved on main equipment, flow load work is undertaken by main equipment；When main equipment breaks down, IP address automatically switches to standby
On equipment.
Preferred as technique scheme, translate domain names into out one group of IP address, each IP address is compiled as one
Group of routes, comprises 2 service equipments in each group, this two service equipments enable simultaneously；And each equipment is on different IP ground
In the group of location.
Advantages of the present invention：
(1) do not need to increase new load-balancing device, completely by the routing function of switch, realize load balancing work(
Energy.
(2) in certain IP address group, when master-failure, different according to the priority of Routing Protocol, can automatically cut
Change on stand-by equipment it is ensured that the seriality of service.Due to using active and standby agreement, the different of whole IP address will not occur
Often shake.
(3) when a failure occurs it, because being Routing Protocol aspect, recovery time can be very fast, about at 1 second about.
