摘要

目前,信息通信技术(ict)的不断发展使得需要在网络上自动和个性化地部署资源的应用和服务得以创建。然而,传统的或继承的基础设施由于其改造所意味着的成本而带来创新困难,因此有必要找到有效管理现有资源的替代方案。基于每个设备的控制平面与数据平面的解耦,将其放置在一个集中的实体中,出现了一种新的范例,从而为基于软件的技术的使用让路。本文提出实现软件定义的广域网(SD-WAN)连接两个软件定义的数据中心,保证了预定义的服务质量(QoS)和流量优先级。在VoIP业务控制的情况下进行了一些模拟,测量了带宽、延迟、抖动和CPU负载。在得到的结果中,证明了上述解的有效性。

Implementation of a SD-WAN for the interconnection of two software defined data centers
At present, the constant development of information and communication technologies (ICTs) is allowing the creation of applications and services that require the automated and individualized deployment of resources on the network. However, the traditional or inherited infrastructure presents innovation difficulties as a consequence of the cost that its adaptation would imply, therefore it is necessary to find alternatives that efficiently manage the existing resources. A new paradigm arises based on the decoupling of the control plane from the data plane of each device to place it in a centralized entity, giving way to the use of software-based technologies. This paper proposes the implementation of a wide area network defined by software (SD-WAN) to connect two data centers defined by software, which guarantees a predefined quality of service (QoS) and traffic prioritization. Several simulations are carried out in scenarios governed by VoIP services and bandwidth, delay, jitter and CPU load are measured. Among the results obtained, the validity of the mentioned solutions is demonstrated.
