The IPv6 QoS Parallel Internet has been developed as a part of the IIP System, which is the result of the project “Future Internet Engineering”. The architecture of the IIP System applies virtualization concept for supporting a number of Parallel Internets while using the same physical network infrastructure. The management system will be presented as well as exemplary cases of Parallel Internet and virtual network creation. The proposed solution has new functionalities related to virtualization of nodes and links in comparison to the management systems of autonomous IPv6 QoS networks.

The IPv6 QoS is one of the Parallel Internets we consider for the IIP System designed in the scope of the project “Future Internet Engineering” (in Polish: “Inżynieria Internetu PrzyszłoĞci”, IIP) [3]. The term “Parallel Internets” means that we consider a number of specialized Internets with different protocol stacks. Parallel Internets share the same physical network infrastructure enabling virtualization of nodes and links. The data transfer inside one Internet should be performed in isolation from the data transfer performed in the rest of coexisted Internets. For the IIP System we have considered three Parallel Internets: IPv6 QoS, Content Aware Networks, and Data Stream Switching. We assume that the management system of each Parallel Internet should be functioning in isolation. The IIP architecture consists of 4 main levels [3]: Physical infrastructure, Virtualization, Parallel Internets, and Virtual Networks. Moreover, on the top of these levels there are Applications/Services, and of course all of these levels require a management system. In this paper we focus mainly on the management system and processes developed for the IPv6 QoS Parallel Internet. We assume that this Parallel Internet operates on IPv6 protocol stack and meets strict QoS requirements. Therefore, QoS guarantees assumed for selected flows are forced by DiffServ PHB (per hop behavior) mechanisms [10], [11], as well as NGN [9] transport (Transport Control Functions and Transport Functions) and service stratum functionalities. All of these functionalities we define at level 3 of the IIP System architecture; this makes the IPv6 QoS system similar in concept to an IPv6 autonomous system. Therefore, this Parallel Internet provides similar functionalities as the IP QoS System defined e.g. in [2] or [1] and [8]. Nodes of this Parallel Internet follow IPv6 node requirements as presented in [8]. Due to the requirement that the IIP System should operate on the physical infrastructure enabling virtualization, it is also necessary to implement the IPv6 QoS mechanisms in the devices enabling virtualization. We selected the following devices: XEN, EZappliance, and NetFPGA cards [3]. For the IPv6 QoS Parallel Internet we also specify virtual network functionalities at level 4 of the IIP System architecture. For now, we have distinguished between four types of processes in the IPv6 QoS system, which operate on different time scales: • Management process: creation/removal and provisioning of network for the IPv6 QoS Parallel Internet (long time scale: months-years); • Management process: creation/removal and provisioning of virtual networks (long time scale: months); This work has been partially supported by the Polish Ministry of Science and Higher Education under the European Regional Development Fund, Grant No. POIG.01.01.02-00-045/09-00 Future Internet Engineering. 8th IEEE, IET International Symposium on Communication Systems, Networks and Digital Signal Processing 978-1-4577-1473-3/12/$26.00 ©2012 IEEE
