Load Balancing In The Enterprise Network

Along with the progress of communications and network technology in the 21st century, the Internet has been rapidly developed. Many traditional businesses begin to move their partial or entire businesses to the Internet as soon as they realized the development prospects of e-commerce. The rapidly increasing business traffic has caused the sharp rise in the network data traffic, especially for those Enterprise data centers or the portal sites, whose data traffics have reached the amount of 10Gbit/s level. The servers in these environments can easily run at full load conditions, while service interruptions may frequently occur and cause economic losses. So, it is necessary to backup the servers and load balancing when the servers are functioning. What's more, considering the interconnection between the north and the south China Telecom, many enterprises had to access the Internet by using the services provided by two or more service providers. The more-than-one export links has motivated us to invite load balancing among links to ensure flexible and average Services.The thesis discusses the problem of load balancing based on the First Promoting Program of the network optimization of Sichuan Tobacco. There will be a new alliance business system to replace the existing online ordering system in Sichuan Tobacco, so it must ensure that the system can run all day and trouble-free with high performance, for this demand, first of all, the new business alliance system server will be cluster to achieve its redundancy requirements, and then load-balancing the server cluster; There is only one export that is China Telecom of Sichuan tobacco at the original, according to the export bandwidth requirements, so expand the bandwidth of the telecommunications access, and leased China Unicom and China Mobile two Internet service providers, At last, the link load balancing can be balance and sharing flow form the three exports of Sichuan tobacco.According to the demand of the construction of a new alliance business system, considering the basic situation of Sichuan tobacco, after a full analysis, the main works have been done can be summarized as follows:1. We use a server cluster to backup the servers; 2. We broaden the export bandwidth by using the links provided by China Telecom, China Unicom and China Mobile.3. We use the balancing techniques to invite load balancing among the three links of the server cluster.
