Backscatter from the Data Plane -- Threats to Stability and Security in Information-Centric Network Infrastructure
Computer Networks,

Zusammenfassung: Information-centric networking (ICN) raises data objects to first class routable entities in the network and changes the Internet paradigm from host-centric connectivity to data-oriented delivery. However, current approaches to content routing heavily rely on data-driven protocol events and thereby introduce a strong coupling of the control to the data plane in the underlying routing infrastructure. In this paper, threats to the stability and security of the content distribution system are analyzed in theory, simulations, and practical experiments. We derive relations between state resources and the performance of routers, and demonstrate how this coupling can be misused in practice. We further show how state-based forwarding tends to degrade by decorrelating resources. We identify intrinsic attack vectors present in current content-centric routing, as well as possibilities and limitations to mitigate them. Our overall findings suggest that major architectural refinements are required prior to global ICN deployment in the real world.

Mobile Multicast Source Support in PMIPv6 Networks
EURASIP Journal on Wireless Communications and Networking, 2013(1):152

Zusammenfassung: With the widespread use of multimedia contents via mobile nodes (MNs), IP mobile multicast becomes more important for wireless, mobile, and ubiquitous multimedia applications. Until now, many research efforts have been made to provide IP multicast for the MNs. However, the existing mobile multicast schemes mostly focus on the mobility of receivers based on the host-based mobility solution that requires the MN to participate in the mobility management. Recent work has shown that service connectivity for mobile multicast sources is still a problem and attracts very little concern. With the development of the network-based mobility support protocol, mobile multicast source support schemes in Proxy Mobile IPv6 (PMIPv6) networks are needed urgently. In this paper, we propose a base solution (BS) and also a direct multicast routing scheme (DMRS) for mobile multicast source support in PMIPv6 networks. In the BS, the multicast listener discover (MLD) proxy function is adopted to transmit multicast data through the PMIPv6 tunnel. The DMRS can provide locally optimized traffic flows and avoid inefficient routing present in the BS. We evaluate and compare the performance of the proposed schemes with the Mobile IP bidirectional tunneling (MIP-BT) and Mobile IP remote subscription (MIP-RS) schemes by theoretical analysis and also implement the proposed schemes on the test-bed. The numerical results show that the BS and DMRS outperform the MIP-BT and MIP-RS in terms of signaling cost. Meanwhile, the experimental results verify the feasibility and validity of our proposed schemes. Furthermore, we study the optimal PMIPv6 domain size to reduce the total signaling cost for the proposed schemes.

On Name-based Group Communication: Challenges, Concepts, and Transparent Deployment
Computer Communications,

Zusammenfassung: Human-centric naming will largely facilitate access and deployment of network services in a future Internet. Information-centric networking (ICN) introduces such vision of a name-oriented, secure, globally available publish-subscribe infrastructure. Current approaches concentrate on unicast-like pull mechanisms and thereby fall short of naming and automatically updating content at groups of receivers. In this paper, we adopt the information-centric paradigm, but argue that an inclusion of multicast will grant additional benefits to the network layer. Our contribution bridges the gap between requesting content by name and applying requests to a scalable distribution infrastructure in a many-to-many communication model. We introduce a group-oriented naming concept that integrates the various available group schemes, simplifies rendezvous processes, and introduces new use cases. We present an open-source prototype of this name-oriented multicast access implemented in the HAMcast middleware.
