  1. SIONA: A Service and Information Oriented Network Architecture Zhongxing Ming Dan Li Chumei Xia Mingwei Xu Tsinghua University

  2. How time flies! Tsinghua University

  3. The Trend • Contents matter more • Web caching • Multicast, video conferencing • Subscription/publication services • Security and privacy • Addresses matter less • Limited in supply. • Some are non-reachable, e.g., private v4, or isolated v6. • More and more are moving. • Quite a few proposals to make network content centric rather than location centric. Tsinghua University

  11. Multihoming ID/Locator split mechanisms try to solve this problem, but they all introduce new indirection, or require some form of rendezvous points to keep reachability. SIONA provides multihoming functionality without path indirection, nor any rendezvous point. Nodes just issue register and request packets using whatever interface they like, and the routing and forwarding mechanism of the network ensures the packets to reach the right destination.

  15. Discussion • SIONA is built on name-based content routing paradigm as is advocated in CCN/NDN. • We differ from CCN/NDN in several ways: SIONA closely keeps the ties to IP. • more like a complementary function of today’s IP network • multi-source multicast and network layer P2P • SIONA differs from DONA in the way that is a tree based architecture, while SIONA is not. SIONA also has different name resolution scheme and routing mechanism. • SIONA gives particular focus on services except for information. Tsinghua University

  16. Conclusion • Content Centric Network is an exciting area in future Internet research activities. • SIONA provides a promising candidate for ICN • Scalable name-based data delivery • Inherent support for mobility and multihoming • Compatible with IP • Multi-source multicast • Network layer P2P • Coordinate caching mechanism • Working in progress Tsinghua University
