Classical Scenario

Current Trends in networking

• Utilization of multiple devices, multiple
  networks and multiple access technologies in an
  integrated fashion
• Support for a rich service layer that relies on
  enhanced and consistent QoS from the network
• IP-based communications control
• But there is a lack of a common control plane
• Different control environments are established to
  facilitate services like VPNs, security,
  mobility, QoS, NAT, multicast
• The control of such services is becoming
  increasingly fragmented

5
Ambient Networks Scope

• The Ambient Network is a pervasive, reliable and
  cost-efficient communication environment that
  supports the ever-changing needs of mobile users
• A uniform control plane would enable the
  assurance of inter-network QoS requirements,
  aiming to guarantee end-to-end QoS
• The concept of Ambient Networking supports the
  creation of
• A uniform control plane for heterogeneous
  networks in order to provide a homogeneous view
  of such networks
• An intelligent ambient in which network
  technologies would be transparently handled

Ambient Networks

• User centric approach Ambient Intelligence
• Seamless and consistent services across
  heterogeneous environments
• Capable of adapting to different environments
• Facilitates the selection of access networks,
  network providers, services based on user
  preferences and context
• Security and privacy on the network level and
  support for application-level security
• Self-configuring network components
• Incorporates P2P, M2M and Ad-hoc communication

8
Mission of Ambient Networks

• Solutions for mobile and wireless systems beyond
  3G
• Enable scalable and affordable wireless
  networking while providing rich and easy to use
  communication services for all
• Comprise a complete, coherent wireless network
  solution
• An architecture for self-configuring network
  components that reduces deployment and
  operational costs and a complete protocol suite
  for network composition evolved from IPv6

9
Strategic Goals

• To define an scalable and affordable wireless
  communication network to enable new ways to
  communicate
• Dynamic composition of networks
• Horizontally structured mobile networks
• To achieve a broad industry consensus on ambient
  networking, creating new business opportunities
  for mobile network service provisioning
• Allowing increased competition and cooperation
  enabling efficient use of resources in an
  environment populated by a multitude of devices,
  technologies and business actors
• To develop a solution that provides easy to use,
  rich and trustworthy multimedia communication
  services for all
• Combining enriching current wireless networks
  rather than creating a new technology
• AMBIENT NETWORKING

10
Technical Objectives

• Complete and coherent solutions for ambient
  networking, based on a range of different
  scenarios and business cases
• Ambient Networks solution sets new standards for
  future context-aware, multi-domain mobile
  networks
• Ensure the Commercial viability by identifying
  business roles and interfaces as well as
  deployment concepts and to consider business
  scenarios that allow different size and types of
  players to compete and cooperate and hence enable
  new business models based on established trust
  relationships
• Validate the various technical solutions
  developed by proof of concept activities in all
  workpackages

Ambient Networks Features

• Composition
• A mechanism that instantly and dynamically
  provides means for networks to compose adhoc
• Service Support
• As an embedded offer for service providers who
  want access to network layer information or need
  advanced handling of media flows
• Mobility
• Mobility concepts that not only target inter and
  intra-domain mobility in static networks, but
  also integrating localized communications
• Heterogeneity
• A new approach is taken that embraces
  heterogeneity at different layers, such as link
  technologies, IP versions, user and network
  contexts, and different media formats
• All control functions
• Mobility support, context management and network
  management, within an Ambient Network domain are
  comprised into one control space, called the
  Ambient Control Space(ACS)

Ambient Control Space

• Insulates Ambient control functions from
  connectivity details
• Abstracts user plane
• Similar integration of legacy networks

Ambient Interface

• The Ambient Networks Ideas

20
Ambient Network Interface(ANI)

• Composition Two Ans negotiate (plug-and-play)
  through ANI and, if an agreement is reached, they
  compose
• Mobility management protocols and who handles
  what
• Security agreement
• QoS, resource optimization
• Discovery
• etc
