一种自适应双阈值NAT-PT簇负载均衡技术研究

Research of Load Balance of NAT-PT Cluster Based on Adaptive Dualthreshold

针对传统IPv4/IPv6过渡技术中NAT-PT簇负载不均衡问题,提出一种自适应双阈值NAT-PT簇负载均衡方法。该方法以DNG-ALG为负载均衡器,通过实时收集各NAT-PT节点的负载信息,根据系统当前状态选择合适的NAT-PT节点,避免了积累效应。实验结果表明,自适应双阈值NAT-PT簇负载均衡技术实现了NAT-PT簇动态负载均衡,减少了相应时间,提高了网络系统吞吐率,具有一定的实际应用价值。

To deal with the problem of the load imbalance of NAT-PT cluster in the IPv4/IPv6 transition technology, a method for load balance of NAT-PT cluster based on adaptive dual-threshold was put forward. DNS-ALG, as the load scheduler, could collect the load information of NAT-PT node in current situation, and select the appropriate NAT-PT node to avoid a cumulative effect. The results showed that the NAT-PT based on adaptive dual-threshold achieved dynamically the load balancing of NAT-PT cluster, reduced time, improved system throughput with certain value of practical application.
