DESCRIPTION

Internet users are able to reach any server from any access point at any time due to the interconnection and the exchange of IP traffic between about 40,000 different Autonomous Systems. The underlying business model for traffic exchange generates concerns among the network service providers (NSPs), resulting in deadlocks that are challenging the internet ecosystem. We introduce the Sending Party Network Pays (SPNP) model and demonstrate why this model can be considered to be a prerequisite to the deployment of QoS. We also outline ecosystem issues that can be addressed through this model and discuss its limitations.

  • 5. But we do not have asimilar option for the Internet! 5
  • 6. Thats how we like it: NO CONGESTION! 6
  • 7. But the reality is often more like this!Solution? Add some lanes! 7
  • 8. Well, are you surethat many lanes will indeed solve the problem? 8 wzfvb

  • 14. Sending Party Network Pays Principle Adresses the question of who pays for the transport of traffic over an interconnection Should always be the sending side network when two NSPs are involved.

  • 15. Sending Party Network Pays Principle Why no End-to-End QoS without SPNP? Only the sender is in the position to decide which IP packets need premium quality (i.e. marking the IP Packet with the express tag) To inform the receiver that this packet needs special care The Idea of the SPNP is inspired by other industries, e.g. parcel or mail services Receiving party would not be interested in paying for QoS IP Traffic which then also has to be forwarded within their network The SPNP model does not address all the issues challenging the internet but contributes to enhance the eco-system. The Model just applies to the wholesale IP Interconnection Business Does not address how the traffic receivers actually pay for the content they receive.

  • 19. Sending Party Network Pays PrincipleWhy no End-to-End QoS without SPNP? Consider a Receiving-Party-Network-Pays-Model in the Internet for a Moment: Incentives to send many packets in high quality classes and to generate revenues These out payments of the ISP would be invoiced to the ISPs customer The customer would refuse this, if he receives undesired IP packets (e.g. spam) RPNP would even enlarge fraud and spam problems RPNP would be more complex than SPNP from a business process, IT systems and legal point of view Business Model Innovation / Sending Party Network Pays 19 b v f z w
