“…The common topology discovery and delivery path formation mechanisms such as OSPF [8] can be easily implemented using publish-subscribe pattern. Furthermore, such implementation can be applied in information-centric architecture as illustrated in our previous work [9]. Therefore, the publish-subscribe paradigm is proven to be flexible enough for supporting not only content retrieval, as already present in many Internet applications, but also more fine-grained functions such as topology discovery.…”

In this work we analyze topology discovery and the procedure for joining the network in the information-centric context. We develop and evaluate such a network attachment procedure in an information-centric network utilizing the publishsubscribe paradigm for the data exchange. In our work the publish-subscribe concept is not only used as a communication means, but we aim at fully exploiting its characteristics for native merging of fine-grained network operations such as topology management and network connectivity establishment. Such an integration adds not only to the simplicity of the network and efficiency of the network information gathering, but includes the means for handling mobility issues. We examine the performance characteristics of the proposed solution particularly focusing on complexity and introduced message overhead. The evaluation results obtained from the testbed experiments show the outstanding performance in terms of delay, while the signaling overhead remains at a very low level.

“…Another clean slate ICN architecture is the PUR-SUIT/PSIRP where the content is labeled with randomly looking identifiers (hierarchically organized) and the communication primitives are publish and subscribe. The publications are matched to the subscriptions by the rendezvous function while the actual delivery tree from the publisher(s) to the subscriber(s) is built by the topology management function, which is centralized [27]. However, the routing mechanism being source routing-based suffers from the security problems inherent in source routing mechanisms [28], [29].…”

Among the new communication paradigms recently proposed, information-centric networking (ICN) is able to natively support content awareness at the network layer shifting the focus from hosts (as in traditional IP networks) to information objects. In this paper, we exploit the intrinsic content-awareness ICN features to design a novel multi-source routing mechanism. It involves a new network entity, the ICN mediator, responsible for locating and delivering the requested information objects that are chunked and stored at different locations. Our approach imposes very limited signalling overhead, especially for large chunk sizes (MBytes). Simulations show significant latency reduction compared to traditional routing approaches.

“…For example, in the PURSUIT architecture [7] the mediation system consists of the topology management function [31], responsible for constructing the delivery tree between publisher(s) and subscriber(s), and the rendezvous function [32], responsible for matching publisher(s), subscriber(s), and content objects. The mediation system can either determine the shortest path or a path based on predefined traffic engineering objectives [13].…”

In recent years, the information-centric networking (ICN) concept has been attracting increasing attention of the research community. The aim is to overcome intrinsic inefficiencies of the existing host-to-host communication paradigm, as well as to provide new and enhanced services to mobile and fixed users. A key feature of ICN is the support for in-network content caching. In this paper, we present a new cache-aware routing scheme for ICN. Our scheme takes into account the information about the locations of caches in the network and constructs delivery paths for efficient content dissemination. The proposed approach does not impose additional signaling overhead in the network; while at the same time it is agnostic of the cached contents. The performance of the proposed scheme is verified by simulation studies, which show an up to 50% delay reduction compared to traditional routing approaches.
