CC* INTEGRATION-SMALL: ADIABATIC MICROSERVICE LEVEL LOAD BALANCED FORWARDING ON PISA SWITCH FOR ACCELERATING URGENT PROCESSES IN SCIENCE DATA CENTER NETWORKS

校园科学数据中心(Sci.DC)越来越需要支持更多种类的工作负载，这主要是因为许多工作负载是交互的。SCI。分布式控制系统正在使用虚拟化来实现更好的即时分布式资源配置。同样即将出现的还有可以加速大规模协作开发的微服务。虚拟化和基于服务的应用程序需要高级功能，尤其是负载平衡(LB)，而请求方和服务器则以不打折扣的线速在物理主机之间动态移动。最近，使用可编程的PISA硬件，该团队能够设计一个负载平衡交换机QLB，它可以使用一般的加权成本多路径(WCMP)方案来分配和负载平衡负载组，同时以硬件的总线速并发地转发到网络的数据面。它还具有今天的生产规模路径和应用程序基数，克服了基于软件的LBS或早期PISA实现的限制。该项目旨在开发一个可在Sci部署的WCMP负载平衡交换机的原型。华盛顿特区。与智能NIC配合使用时，此智能交换机将准备好以多种方式从网络内部提供负载平衡。如果成功，这项技术将显著消除校园科学中与当前一代基于软件的负载均衡相关的延迟和可扩展性限制。集散控制系统。它还将提供对与部署和操作可编程交换机相关的安全、配置和维护问题的早期洞察。根据CC*计划的目标，这将直接促进校园级网络基础设施的协调改进、创新、集成以及科学应用和分布式研究项目的工程。该项目将提供对可编程网络基础设施的全新接触--这是肯特校园IT团队和许多其他校园的第一次。该项目还将产生重大的更广泛的影响：它将使本科生在STEM科学团队中进行跨学科指导的研究实习，这在留住和吸引代表性不足和处境不利的学生方面特别有效。这一奖项反映了NSF的法定使命，并通过使用基金会的学术价值和更广泛的影响审查标准进行评估，被认为值得支持。

Campus science data centers (Sci. DC) increasingly need support for more varied classes of workloads, mainly because many are interactive. Sci. DCs are using virtualization for better just-in-time distributed resource provisioning. Also on the horizon are the microservices that can accelerate collaborative development at scale. Virtualization and service-based applications demand advanced functionalities, particularly load balance (LB), while the requesters and servers are dynamically moving between physical hosts at uncompromising line rates. Very recently, using programmable PISA hardware, this team was able to design a load-balancing switch, QLB, that can distribute and load-balance load groups with a general weighted-cost multi-path (WCMP) scheme while concurrently forwarding to the network’s data plane at the total line rate of the hardware. It also has today's production-scale path and application cardinality, overcoming limitations of the software-based LBs or early PISA realizations. The project aims to develop a prototype of this WCMP load balancing switch that is deployable at Sci. DC. In conjunction with smart NICs, this smart switch will be ready to offer load balancing from inside the network in multiple modalities. If successful, this technology will significantly remove the delay and scalability limitations associated with the current generation software-based load balancing in campus Sci. DCs. It will also provide early insight into security, configuration, and maintenance issues related to deploying and operating programmable switches. In line with the goals of the CC* program, this will directly contribute towards coordinated campus-level cyberinfrastructure improvements, innovation, integration, and engineering for science applications and distributed research projects. The project will provide novel exposure to programmable cyberinfrastructure - the first for Kent’s Campus IT teams and many other campuses. The project will also have a significant broader impact: it will engage undergraduate students in interdisciplinary directed research internships with STEM science teams, which is especially effective in retaining and attracting underrepresented and disadvantaged students. It will empower science projects at Kent State across disciplines.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
