  10. DHT Internetworking Architecture At the core, we do not want a global DHT of all nodes. Instead, peer’s core NID router (NR3) is passed in the packets. A small DHT can look up the locator of NR3. DNS retrieves Node ID of peer (B), and Node ID of peer’s core router (NR3) LD1 (IPv4 Core) Locator domains have independent address spaces DNS Nodes have HIP-like Node IDs, self-generated public keys End-to-end security is based on NIDs. NR2 NR3 LD2 LD3 DNS DNS Domains are connected by “NID routers” that route based on destination NIDs A B FFV2006 - Ambient Networks

  11. Integrates local mobility, end-to-end mobility, and network mobility Even makes network-based multi-homing possible A B B A A A (a) (b) (c) B A A Traits of the Internetworking Concept • Initial handshake (~ HIP) provides an always-on security model; subsequent packets are protected • The handshake also has basic DoS protection • Additionally, nodes can manage their NIDs and NID routers in a Hi3-like manner to provide network-based DoS protection • NIDs can be changed on the fly for privacy reasons, and NID routers provide location privacy FFV2006 - Ambient Networks

  12. Network Composition FFV2006 - Ambient Networks

  13. Motivation for Composition • The central concept of Ambient Networks is Composition • Composition is… • a uniform, dynamic procedure for network interworking on the control plane • Uniform procedure • independent of network type and technology • Dynamic procedure • minimize human intervention • Control Plane Interworking regarding • routing, addressing, mobility, QoS, security, charging,.. FFV2006 - Ambient Networks

  14. Composition Use Cases • Types of Composition • Network Integration • Involved networks merge into one common network • E.g. creation of a PAN • Control Delegation or Control Sharing • One AN delegates certain control functions to the other AN • 3GPP-WLAN interworking:WLAN delegates authentication, authorization and charging to 3GPP network • Network Interworking • Cooperation according to the Composition Agreement but no control delegation • E.g. dynamic roaming agreements Increasing control plane cooperation FFV2006 - Ambient Networks

  15. Composition - Standardization • The Ambient Networks Project established aStudy Item “Network Composition” in 3GPP SA1 • TR 22.980 „Network composition feasibility study; (Release 7)” • Content • Purpose and benefits of composition • Use cases • Requirement • Composition Process • New functionality in 3GPP networks • Relation to other functionality in evolving 3GPP architecture • AIPN,… FFV2006 - Ambient Networks

  20. Media Delivery FFV2006 - Ambient Networks

  21. Media Delivery using SSONs • Establishment of Service-Specific Overlay Networks (SSONs) using Bearers • SSONs are independent virtual networks for every media delivery service (or group of services) • SSONs allow dynamically tailoring the network to the specific needs of a service • Why do we need SSONs? • Means to include network-side media processors into end-to-end media delivery path • Control application of media functions (where, how, which costs, etc.) • What do SSONs achieve? • SSONs decouple the configuration of virtual networks from the underlying network • SSONs enable flexible configuration of virtual networks in terms of • Topology • Addressing • Routing • QoS FFV2006 - Ambient Networks
