Abstract

In this paper, we have followed the idea of exploiting inter-technology load balancing leveraged by flow admission control with software defined networking (SDN). By means of the highly flexible interfaces, SDN is simply effective in the 5G network architecture where load balancing and dynamic flow admission control are considered as essence of networking. In one hand, load balancing presented in this paper reveals a drastic reduction of unsatisfied-user percentage almost by five times while, on the other hand, it enhances per-flow resource allocation more than %. In addition, this proposal substantially off-loads the core-network, avoids over-utilizing the cellular network and reserves resources based on cut-off priority. Explicitly, it allows a certain degree of freedom to choose the network options based on user-preference and their priorities. Finally, we compare our load balancing algorithm leveraged by flow admission control with an analytical model to ensure the correctness and efficiency.

基于SDN的跨技术负载均衡与流量准入控制
在本文中,我们遵循了利用软件定义网络(SDN)的流量接纳控制来利用技术间负载平衡的思想。SDN凭借其高度灵活的接口,在以负载均衡和动态流量接纳控制为组网本质的5G网络架构中发挥了极大的作用。一方面,本文提出的负载均衡可以将不满意用户百分比大幅降低近五倍,另一方面,它可以将每流资源分配提高超过%。此外,该方案还大幅减少了核心网的负载,避免了蜂窝网络的过度利用,并基于截止优先级保留了资源。明确地说,它允许基于用户偏好及其优先级选择网络选项的一定程度的自由。最后,我们将基于流量接纳控制的负载均衡算法与解析模型进行了比较,以确保算法的正确性和效率。
