Named Data Networking over a Software-Defined Network Using Fixed-Size Content Names Jung-Hwan CHA Youn-Hee HAN Sung-Gi MIN Publication IEICE TRANSACTIONS on Communications Vol.E99-B No.7 pp.1455-1463 Publication Date: 2016/07/01 Online ISSN: 1745-1345 DOI: 10.1587/transcom.2015EBP3464 Type of Manuscript: PAPER Category: Network Keyword: Information-Centric Networking (ICN), Software-Defined Networking (SDN), name tag, ICN deployment problem, Full Text: PDF(2MB)>>
Summary: Named Data Networking (NDN) has emerged as an alternative to traditional IP-based networking for the achievement of Information-Centric Networking (ICN). Currently, most NDN is deployed over IP networks, but such an overlay deployment increases the transport network overhead due to the use of dual network control planes (NDN routing and IP routing). Software-Defined Networking (SDN) can be used to mitigate the network overhead by forwarding NDN packets without the use of IP routing. However, to deploy NDN over SDN, a variable NDN content name needs to be mapped to a fixed-size match field in an OpenFlow switch flow table. For efficient support of such a mapping task, we propose a new architecture that uses dual name for content: content name and Name Tag. The Name Tag is derived from the corresponding content name and is a legitimate IPv6 address. By using the proposed Name Tag, the SDN with an NDN control application can transport an IPv6 packet that encapsulates an NDN packet for an NDN name-based routing. We emulate the proposed architecture using Mininet and verify that it is feasible. | |||||
