CSR: Small: A Scalable and Efficient Framework for Switch Virtualization

该项目通过开发一套带宽分配和分组调度技术作为交换机虚拟化的集成框架来解决网络虚拟化问题。目标是在虚拟网络之间实现可伸缩、高效和隔离的链路共享。通过重新组织公共物理基础设施的资源，网络虚拟化允许创建多个共存的逻辑网络，每个网络都针对特定目的进行定制。网络虚拟化在降低硬件成本、提高资源利用率、简化维护和增加服务部署方面有许多重要的应用。网络虚拟化的实现依赖于为底层物理基础设施的各种资源创建片。然而，需要有效的解决方案来为交换机创建切片，交换机是任何网络的重要互连组件。该项目为交换机虚拟化开发可伸缩性和效率感知链路共享（SEALS）框架。本项目考虑了两种类型的交换机虚拟化：交换机内虚拟化（在一个物理交换机中创建多个逻辑交换机）和交换机间虚拟化（将多个异构物理交换机组合在一起创建逻辑交换机）。seal框架精确地模拟了理想的通用处理器共享（GPS）模型，以实现可扩展、高效和隔离的交换机虚拟化。结合理论分析、模拟和实验来评估设计。在OpenFlow交换机中实现了seal框架，以从现实环境中获取实验数据。该项目的成果将促进商业和学术虚拟网络的创建，以建立节省成本的基础设施或试验新的网络原型。这个项目的教育部分通过夏季研讨会、课程开发和本科研究项目，为代表性不足的少数群体提供了计算机研究机会。佛罗里达国际大学是美国向西班牙裔学生提供计算机科学和工程学位的顶尖大学之一。它在研究工作中涉及代表性不足群体的历史将在这个项目的过程中得到利用。项目网站将用于传播项目产生的所有出版物、课程材料和源代码。

This project addresses network virtualization by developing a suite of bandwidth allocation and packet scheduling techniques as an integrated framework for switch virtualization. The goal is to achieve scalable, efficient, and isolated link sharing among virtual networks. Network virtualization allows for the creation of multiple coexisting logical networks, each customized to a specific purpose, by reorganizing the resources of a common physical infrastructure. Network virtualization has many important applications in delivering reduced hardware cost, improved resource utilization, simplified maintenance, and incremental service deployment. Implementation of network virtualization relies on creating slices for various resources of the underlying physical infrastructure. However, effective solutions are needed to create slices for switches, the important interconnecting components of any network. This project develops Scalability and Efficiency Aware Link Sharing (SEALS) framework for switch virtualization. This project considers two types of switch virtualization: intra-switch virtualization which creates multiple logical switches within a physical one, and inter-switch virtualization which creates a logical switch by combining multiple heterogeneous physical ones. The SEALS framework accurately emulates the ideal Generalized Processor Sharing (GPS) model to realize scalable, efficient, and isolated switch virtualization. A combination of theoretical analysis, simulations, and experiments are used to evaluate the design. The SEALS framework is implemented in OpenFlow switches to obtain experimental data from a realistic environment. The outcome of this project will facilitate the creation of commercial and academic virtual networks to build cost-saving infrastructure or experiment new network prototypes. The educational component of this project offers research opportunities in computing to underrepresented minority groups, through summer workshops, curriculum development, and undergraduate research programs. Florida International University is among the top grantors of computer science and engineering degrees to Hispanic students in the nation. Its history of involving underrepresented groups in research efforts will be leveraged during the course of this project. The project web site will be used for dissemination of all publications, course materials, and source code resulted from the project.
