However, implementing network load
the only line. That's pretty thorough. DNS polling is the simplest and most effective way to achieve load balancing, with very low cost in all respects. The goods are very cheap and enough. The disadvantage is that because there is no detection mechanism, not balanced, fault-tolerant response time is long. Domestic portal with a lot of this technology, with
As the number of users accessing CEN servers increases dramatically, it is difficult for a single server to meet users' access needs. How can we ensure normal user access? There are many solutions, such as using Windows2000 or WindowsServer2003 to provide the network load balancing service, but the settings of this service are very complicated. However, implementing network
design needs to consider the relationship between different servers, once you want to change the relationship between the server, it will make some Web page connection error , is not conducive to maintenance, scalability is also poor. Another design structure of the multi-server is symmetrical structure, each server in the symmetrical structure has the equivalent status, can provide the service separately without the assistance of other servers. Then, with some technology, the externally sent
