Edge->Core vs. Core->EdgeHow will ICN make it into the World?

Computer Laboratory

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?

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!

How Is It Likely to Happen?

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!

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

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
