Automatic Network Services Aligned with Grid Application Requirements in CARRIOCAS Project Automatic Service framework named Scheduling, Reconfiguration and Virtualization (SRV) is developed in CARRIOCAS project to enhance existing Telecom network infrastructures for supporting grid applications sharing IT resources interconnected with ultrahigh performance optical networks. From the requirements of Grid applications a classification is pro po sed to specify the network services and their attributes. In largescale collaborative environments, SRV solution is described to enable automatic network service operations according to highperformance computing service access. The resources hosted at datacenters are virtualized to be attached to transport network infrastructure offering uniform interfaces towards external cus tomers. New level of service bindings is defined with network services du ring executions of Grid applicationsxe2x80x99 workflows. Ondemand intensive com puting and visualization services scenario is described in Telecom environment.

SCinet DTNasaService Framework Transferring big data over Wide Area Networks (WANs) is challenging because optimization is dependent on the specifics of multiple parameters. Network services, paths, and technologies have different characteristics, including loss rate, latency, and available capacity. Yet, frameworks currently used to configure and orchestrate transfer systems, measure performance, and analyze results have limited capabilities. We propose a framework, DTNasaService (DaaS), for highperformance network data transfers using and integration of techniques, including virtualization, network provisioning, and performance data analysis. This framework has a modular design for supporting multiple transfer tools, optimizers and orchestrators for the data transfer environment, including textitDocker and textitKubernetes. We present a textitJupyter based workflow for highspeed network data transfer in dataintensive science and evaluate the performance of the transfer with a simple programmable visualizer implemented in the framework. This framework has been implemented as a prototype at two recent SC supercomputing conferences. With the increase in the number and the capacity of WAN links at the conferences (multiple 100 Gbps WAN circuits), the challenges involved in setting up, testing, debugging, verifying and running applications on highperformance systems connecting to the conference SCinet WAN circuits also increase. The SCinet implementation of the DaaS framework for the conference community allowed users to control hardware, software, and network infrastructure for highspeed network data transfer, primarily for large scale applications. Through the evaluation of the framework in our test setup, we demonstrated that NVMe over Fabrics with TCP is twice as efficient compared to using conventional TCP in highspeed NVMetoNVMe transfers. We also implemented a 400 Gbps LAN experiment to evaluate the DaaS framework.
