Web Load Balancing Based on DNS Coordination and Reducing Energy Consumption Strategy

Abstract

With the massive application of Web services and streaming media, Web cluster deployment in a single physical area can no longer meet the network requirements. Currently, with a range of WAN Web cluster deployment, the delegation points can access the nearest Web cluster and reduce the average distance of data flow, thus reducing network latency. Therefore, it is particularly important for cluster load balancing to quickly obtain access node information and redirect Web clusters that need to be accessed by the nodes. At the same time, the power consumption of computers and the power consumption of multi-area deployment of Web clusters are huge, and more computer resources are wasted in the low-access period, so it is also essential to reduce the power consumption of the entire load balancing. In order to solve the above two problems, this paper proposes a web load balancing method which can reduce the energy consumption of the cluster and DNS collaboration. It provides information for accessing the nodes to the load balancing and uses the cosine distance to quickly locate the web clusters that the nodes need to access. Meanwhile, Cluster energy consumption strategy to reduce the energy consumption of the entire cluster.
