Summary
This position paper argues that Internet architectural design should be reframed as an interdisciplinary, socially-driven endeavor that integrates social capital theory with networking research. The authors trace the user’s evolution from passive consumer to prosumer and ultimately to network prosumer — a role embodied in User-centric Networks (UCNs) where end users share and operate connectivity resources at lower OSI layers. They diagnose the current Internet supply chain as structurally asymmetric, with traffic-growth benefits unevenly distributed across its seven stages, and propose a symmetric variant that explicitly incorporates prosumers and UCNs. The paper further contends that social capital properties — trust, influence, reach, and engagement — should be operationalized as networking metrics, and that mismatches between social and networking interpretations of centrality must be resolved.
Key Contributions
- A vision and set of design guidelines for a socially-driven Internet architecture that blends social capital theory with networking design.
- Extension of the prosumer concept into lower network layers via the “network prosumer” notion, grounded in User-centric Networks.
- A symmetric Internet supply-chain model that explicitly includes prosumers and UCNs as stages, contrasted with the prevailing asymmetric model.
- A comparative mapping between social capital centrality concepts (degree, betweenness, closeness) and their networking analogues, surfacing specific misalignments.
- Identification of reach, engagement, and influence as the social properties most readily operationalizable into candidate networking metrics, especially for pervasive and opportunistic routing.
Methods
Conceptual, interdisciplinary position paper. The authors synthesize literature from networking research projects (GENI, EIFFEL, SocialNets, ULOOP) and social capital theorists (Bourdieu, Coleman, Putnam, Burt). They use the seven-stage Internet supply-chain model from Pigliapoco and Bogliolo as their diagnostic framework, perform a comparative analysis of centrality definitions across the two fields (summarized in a comparison table), and outline a socially-driven design cycle connecting social media, open data, social behavior models, and emerging media/business practices.
Findings
- Vertical integration by operators clashes with the modular TCP/IP stack, constraining innovation and producing cost/price misalignment.
- Within the seven-stage supply chain, stages 2, 3, 5, and 7 capture gains from traffic growth, whereas stages 1, 4, and 6 stagnate due to weak price signals.
- UCNs rest on four properties — resource sharing, cooperation, trust, and self-organization — and push prosumer behavior down the protocol stack.
- Centrality concepts diverge across disciplines: high-betweenness nodes function as inter-cluster bridgers socially but as mere relays in networking; high-closeness nodes imply efficient diffusion socially yet often become bottlenecks in networks.
- The bridger role and the transitivity of strong ties are not adequately captured by current pervasive networking models.
- Prosumer activity exhibits power-law characteristics, indicating that consumer and prosumer modes coexist rather than supplant one another.
- Social capital can be modeled at individual or collective levels, with trust and reciprocity central to Putnam’s collective framing.
Connections
No other papers were provided under shared topics, so there are no sibling notes to link here. Intellectually, the paper sits at the crossroads of Future Internet architecture initiatives (GENI, EIFFEL, SocialNets, ULOOP), prosumer theory (Toffler, Ritzer), and classical social capital scholarship (Bourdieu, Coleman, Putnam, Burt) — connections worth establishing as the Zettelkasten grows.
