Design and Implementation of a Software-Defined Approach to Information-Centric Networking
نویسنده
چکیده
This work is concerned with the integration of the two networking paradigms of ICN and SDN in order to provide an enhanced evolutionary path from today’s IP networks towards ICN. We introduce a scheme that allows for the operation of SDN based infrastructure, which provides network-wide ICN awareness. Further, an advanced approach, which allows for the forking of ICN packets throughout the SDN domain is developed and evaluated. This approach introduces the ability of aggregating requests and a mechanism to populate off-path caches as well as the parallel requesting of multiple caches. The qualitative advances that the SDN supported deployment provides compared to a pure overlay deployment are investigated plus the quantitative results of our Implementation. Kurzzusammenfassung Die vorliegende Arbeit beschäftigt sich mit der Integration der beiden Netzwerkparadigmen ICN und SDN. Dabei wird das Ziel verfolgt, einen evolutionäre Migrationspfad von heutigen IP Netzwerken hin zu ICN zu bieten. Wir zeigen ein Schema auf, dass die initiale Bereitstellung eine SDN gestützten Netzwerks mit erweiterter ICN Verarbeitung ermöglicht. Darüber hinaus wird ein erweiterten Ansatz entwickelt und evaluiert, der die SDN interne Duplizierung von ICN Paketen erlaubt. Hierdurch wird neben der Zusammenführung von Inhalteanfragen und Mechanismen zur Befüllung von nicht auf dem direkten Übertragungsweg befindlichen Caches auch die parallele Anfrage mehrerer Caches ermöglicht. Die qualitativen Vorteile eines SDN gestützten, gegenüber einem reinen Overlay-Betrieb werden ebenso beleuchtet, wie quantitativen Ergebnisse unserer Implementierung.

متن کاملSDN Security: A Survey
The pull of Software-Defined Network- ing (SDN) is magnetic. There are few in the networking community who have escaped its impact. As the benefits of network visibility and network device programmability are discussed, the question could be asked as to who exactly will benefit? Will it be the network operator or will it, in fact, be the network intruder? As SDN devices and systems hit the mark...
متن کاملRISC: ICN routing mechanism incorporating SDN and community division
Information-Centric Networking (ICN) is one promising architecture paradigm which is a profound shift from address-centric communication model to information-centric one. Although ICN routing has attracted much attention from researchers, there are few researches on improving it inspired by other fields. In this paper, we propose a Routing mechanism for ICN incorporating Software-Defined Networ...
متن کاملPoor Man’s Content-Centric Networking (with TCP)
A number of different architectures have been proposed in support of data-oriented or information-centric networking. Besides a similar visions, they share the need for designing a new networking architecture. We present an incrementally deployable approach to content-centric networking based upon TCP. Contentaware senders cooperate with probabilistically operating routers for scalable content ...
