Why is IPv6 Deployment Important for the Internet Evolution?, Journal of Telecommunications and Information Technology, 2011, nr 2

Replacing the IPv4 protocol with IPv6 on the Internet is currently one of the aims of the European Union policy. The main reason for this replacement is the effeteness of the addresses pool in the IPv4 protocol, which can cause serious complications in the evolution of the Internet and its adaptation in new areas, e.g., in next generation mobile telephony or the so called Internet of Things. Simultaneously, the addressing capabilities of the IPv6 protocol are practically unlimited and its new functionalities increase the attractiveness of its usage. The article discusses the problems connected with the IPv6 deployment on the Internet. Especially, the rules for realization of the IPv6 deployment and rules for cooperation of IPv4 with IPv6 (including cooperation tests) in network infrastructure and in applications are presented. Moreover, the European projects’ results and the activity’s directions of the national project Future Internet Engineering are discussed

Enabling service market in metro and access networks – the ADDONAS project

SDN/OpenFlow solutions have shown their strengths in datacenter, cloud and experimental environments. Currently there is a number of activities employing SDN concepts to other use cases. The ADDONAS project (Active Distributed & Dynamic Optical Network Access Systems) proposed to use SDN concept to support access to the services for the users and fair access to the resources for service providers. This paper presents the work done in the ADDONAS project, discusses architecture and describes development related to deployment of the SDN system to enable flexible service provisioning in combined metro and access architectures. © 2013 IEEE
