Content-centric networks have been proposed as a new network paradigm that is centered around the distribution of content. A key idea of content-centric networks is to address content by name and to enable nodes in the network to respond to content requests. Most proposals for content-centric networks require a "clean slate" approach and a replacement of today's TCP/IP protocol stack, which...
Content-centric networking is a novel paradigm for the Future Internet that treats content as a first class citizen. This paper argues that content-centric networking should be generalized towards a service-centric networking scheme. We propose a service-centric networking design based on an object-oriented approach, in which content and services are considered objects. We show implementation architectures...
We analyze in detail the content retrieval process in kad. kad implements content search (publish and retrieval) functions that use the Kademlia Distributed Hash Table for content routing. Node churn is quite common in peer-to-peer systems and results in information loss and stale routing table entries. To deal with node churn, kad issues parallel route requests and publishes multiple redundant copies...
