  1. Edge->Core vs. Core->Edge How will ICN make it into the World? Computer Laboratory

  2. A Core-driven Story • Two aspects potentially interesting for (core) ISPs • Caching transit traffic • Multicast and policy support at inter-domain level • Problem • Caching is not compliant with the incentive to incur traffic charges • Same goes with multicast -> requires changes to the incentive models for the core ISPs -> could be driven by green, efficiency and policy aspects But altimately: why killing my cash cow?

  3. An Edge-driven Story • Information dissemination is at the heart of many industries • Retail, news, finance, content, … • But also mobile and access ISPs (accommodating local access of information) • Efficient delivery of what is important (information) • Caching & multicast support • Support of edge networks (such as wireless) • Path computation important, e.g., for accommodating cross-value chain scenarios!

  4. How Is It Likely to Happen? Proprietary Silo Solutions Content Health Driven by need to support policy- compliant inter- connection of information Driven by need for internal inter- connection & cross-value chain collaboration Gov. Retail Tiered inter-connection Growing from core to edge Growing from edge to core Questions ownrevenue! Akin to the growth of P2P Core Internet

  5. Native vs. Overlay Deployment • Both models need support! • Overlay possibly more important for inter-domain & international deployments • Native can be done in intra-domain solutions, e.g., service solutions for customers • Connection to SDN and virtualisation techniques important! • Focus on efficient intra-domain fast & slow path important! • Get to things fast and efficient! -> PSIRP D4.6 studied native vs overlay deployment!

  6. What (Edge) Industries Could Push ICN? • Mobile/Access ISPs • Dealing with content (caching and multicast proposition) • Broadcasters and content producers • Highly personalised and interactive content (and increasingly over mobile) • Finance and news • Information at your fingertip • Smart cities • Internet of Things at scale

  7. What is Needed to Make it Successful? • Treat ICN as a new entrant compared to the incumbent IP • Focus on secondary features: what is it that the highly content-focused IP can’t do well? • Possible avenues: • Interactivity? Policy compliance? • Large degree of mashing up relevant but unhosted content? • Sheer scale or efficiency? • Most importantly: the new entrant ICN needs the commercial counterpart • Candidates: an incumbent renewing itself OR the new Cisco
