对ONOS Intent接口进行基准测试，以简化5G服务管理
Benchmarking the ONOS Intent interfaces to ease 5G service management
摘要：
即将到来的5G移动网络的用例引入了新的和复杂的用户需求，这些需求将需要支持网络资源的快速重新配置。软件定义网络（SDN）是可以解决这些需求的关键技术，因为它将控制平面从网络设备的数据平面中分离出来，并且在逻辑上将控制平面集中在SDN控制器中。SDN网络操作系统（ONOS）是一种最先进的SDN控制器，旨在从其设计中解决这一重要的可扩展性限制。ONOS的一个重要特性是，它允许网络管理员使用Intent规范来配置和管理具有高抽象级别的网络。Intent是一个策略表达式，描述了期望的结果是什么，而不是如何达到结果。意图的概念加上分布式存储空间是ONOS理论可扩展性的关键组成部分。在本文中，我们提出了我们的评估的ONOS意图北向接口使用的方法，考虑到接口访问方法，类型的意图和安装的意图的数量。我们的初步分析表明，计算成本与提交的Intent数量呈线性增长，访问方法是整体计算成本的主要因素。
英文摘要：
The use cases of the upcoming 5G mobile networks introduce new and complex user demands that will require support for fast reconfiguration of network resources. Software Defined Network (SDN) is a key technology that can address these requirements, as it decouples the control plane from the data plane of the network devices and logically centralizes the control plane in the SDN controller. SDN network operating system (ONOS) is a state-of-art SDN controller that aims to address this important scalability limitation from its design. An important feature of ONOS is that it allows network administrators to configure and manage networks with a high-level of abstraction by using Intent specifications. An Intent is a policy expression describing what is the desired outcome rather than how the outcome should be reached. The concept of Intents coupled with the distributed storage space are the key components for the theoretical scalability of ONOS. In this paper, we present our evaluation of the ONOS Intent northbound interface using a methodology that takes into consideration the interface access method, type of Intent and number of installed Intents. Our preliminary analysis indicates a linear increase in the computational cost with regards to the number of submitted Intents, with the access method being a major factor in the overall computational cost.
