socioeconomic tussles analysis of the etics approach for providing qos-enabled inter-domain services
DESCRIPTION
Tussle analysis helps better understand the interrelations between Future Internet technologies and socio-economics. Its purpose is to study how such stakeholders interact by exploiting Future Internet technologies to advance their economic interests and influence economic outcomes. The presentation will motivate and apply a generic methodology for tussle analysis to the ETICS Approach for Providing QoS-enabled Inter-domain Services.TRANSCRIPT

Allowing the control of major parameters of interconnection is important for promoting collaboration that is mutually beneficial
What are the necessary business conditions for QoS-aware interconnection?

Iteration 2a:What if an ASQ good is used by ISP-2 to bypass the Best-Effort peering link for all traffic?
?
Iteration 2b:What if ISPs could control major properties of ASQ goods?
ISP-1
Iteration 3:What if ISP-1 stopped offering that ASQ?
Iteration 1:Support for best-effort connectivity only
ISP-2 feels unfair
ISPs perform traffic engineering for optimizing network usage
Functionality: Network Service composition
Introduction of ASQ goods make routing more stable and simpler

Concluding remarks
• Internet technologies can have impact on:• stakeholders by triggering establishment of new
strategies / business models• other technologies (functionalities) by triggering
creation of new technologies
• “Tussles friendly” technologies allow for balanced control between stakeholders • Better incentives for adoption in the long-run• … but, requires significant effort from technology
designers for understanding the ecosystem

• At each stage conflicts of interest (incentives) arise at the socio-economic layer.
• The combination of actors’ strategies lead to a tussle outcome, characterized by stakeholders benefits.
