在自组织网络中的自动化和SDN

Automation and SDN in Self-organizing Networks

软件定义网络(SDN)在网络管理领域十分重要。SDN解决了供应商的锁链(lock-ins),这样的网络变得可编程化。文中主要描述SDN、自动化网络管理(ANM)和重要的范例在长期演进技术(LTE)中的自组织网络(SONs)。首先介绍SDN的定义、发展过程以及SDN的特点和一些重要的特性;其次,主要介绍自动化和自动化特征;然后介绍自动化SDN,其结合自动化网络以及SDN技术。为了更加简单地网络管理方式,展示了AUTOSDN的网络架构和其中的一些原件。最后用一个AutoSDN的应用来介绍具体的应用场景。文中用一个自动化的软件定义网络(AutoSDN)以及自组织网络来加强线下加载(off-loading)的能力,结构显示网络的利用率在网络中得到了显著的提高与优化。

Software defined network(SDN)is very important in the field of network management.SDN solves the lock-ins of suppliers,and such networks become programmable.This article describes SDN,automated Network Management(ANM),and the important paradigm for self-organizing networks(SONs)in long Term Evolution(LTE).Firstly,the definition,development process,characteristics and some important characteristics of SDN are introduced.Secondly,mainly introduces automation and automation features;Then it introduces automatic SDN,its combination with automatic network and SDN technology.To make network management easier,the network architecture of AUTOSDN and some of its components are shown.Finally,an application of AutoSDN is used to introduce the specific application scenario.In this paper,an automated software defined network(AutoSDN)and a self-organizing network are used to enhance the capability of off-loading.The structure shows that the utilization rate of the network has been significantly improved and optimized in the network.
