PRISTINE use cases will be based on three well-defined scenarios, targeting different realistic deployments of RINA interoperating with some of the current computer networking technologies.
SlapOS is a decentralized cloud technology used to build a physically distributed cloud. Customer’s applications are run in traditional datacenters, but also in servers from offices and home users. SlapOS is in charge of managing the overall cloud from a logically centralized location: the SlapOS master (a distributed approach is currently under development). The SlapOS master controls the different computers running SlapOS slaves. In terms of networking, the master and the nodes at different locations are interconnected through multiple IPv6 providers. In order to guarantee a high reliability (99.999%), SlapOS uses an overlay called re6st, which creates a mesh network of OpenVPN tunnels on top of several IPv6 providers and uses the Babel protocol for choosing the best routes between nodes. PRISTINE will provide an alternative to the re6st overlay, by using RINA on top of IPv6.
The datacenter space is one of the areas that has seen more virtual networking innovations during the last few years, fueled by the flexibility requirements of cloud computing. A myriad of SDN-based virtual network solutions, usually providing L2 over L3 or L4 tunnels and a control plane, are available in the market (VXLAN, NVGRE, STT, etc). PRISTINE will investigate and trial the use of RINAbased solutions for intra- as well as inter-datacenter networking. Important issues to be addressed in a datacenter environment are the mobility of Virtual Machines to allow an efficient utilization of datacenter resources as well as high reliability; multi-homing support; guaranteeing the level of service in inter-data center communications and flexible allocation of flows supporting computer and storage resources.
Network Service Provider
The goals of this scenario are to investigate and trial the efficiencies and benefits of a Networks Service Provider (NSP) using the RINA technology, and to analyze RINA as a materialization of the Network Functions Virtualization concept within an operator network. The NSP will internally use several DIFs over Ethernet, in order to transport the traffic of the services provided to the customers: IPv4 and IPv6 Internet access, VoIP, Ethernet, etc., but also native RINA traffic. With PRISTINE solutions the NSP will benefit from DIFs that provide different levels of service, being able to consolidate separate infrastructures. He will also have the tools to better manage the congestion within their networks and provide stronger flow isolation; achieve higher realiability and other benefits.
