Trilogy and 4WARD: Towards a Clean Slate Internet Design

Wolfgang Mühlbauer, Roger Karrer, Peter Feil, Anja Feldmann

  • Clean Slate Internet Design – why?

  • Many of the design decisions of the Internet were made 4 decades ago. Since then, the Internet and its use have changed as it has changed itself society. However, today, the Internet is out of shape.

  • An ossified architecture

  • The Internet architecture is the result of an initial careful design based on well-argued principles and a 4 decade evolution to add additional features. Unfortunately, many of these principles are no longer true (security) or new ones have emerged – technical ones (mobility) as well as economical ones (net neutrality). One thing the Internet lacks is flexibility to efficiently accommodate the new requirements.

  • Control plane: out of shape

  • The picture of the Internet hourglass to depict its architecture holds for the data plane. However, it is far from true when we consider the “control plane”. In fact, there is no such thing as an explicit control plane. And second, control protocols had been squeezed into the architecture to fit the layering structure. Therefore, the Internet architecture has significantly extended its waist over the past 40 years.

  • A clean slate Internet design that searches for novel concepts to build an Internet architecture from scratch is needed to ensure that the Internet is able to address the challenges in the near future.

  • We at Deutsche Telekom are part of 2 EU FP-7 projects that focus on these challenges:

  • 4WARD

  • Triology

  • Even though the two projects aims at similar goals, they take different approaches and focus on distinct challenges.

Trilogy: Re-architecting the Internet

Trilogy’s concept is single architecture that is flexible to adapt to the different forces and demands in the Internet – i.e. a tussle-aware architecture.

  • It identifies 3 fundamental demands that must be consideredjointly in the design of a future Internet architecture

  • Reachability Mechanisms

  • Resource Control

  • Business Aspects

  • Trilogy is the first project that tries to unify all of them in a clean slate approach

  • Workpackage 1: Reachability

  • Establish and control transparent reachability in a scalable, dynamic and resilient manner:

  • Routing fragility

  • Growing organizational complexity

  • Topics include

  • Routing

  • Multi-homing

  • Remote traffic filtering

  • Workpackage 2: Resource control

  • Develop and evaluate a unified approach to resource control that is efficient, fair and incentive-compatible:

  • Utilization

  • Different fairness metrics

  • Cheat-proof

  • Congestion

  • Storage, battery life, spectrum

4WARD

  • 4WARD is based on the following technical premises:

  • Create a new “network of information”, where information objects have their own identity.

  • Rich communication paths that include mobility, security and QoS over wired and wireless networks

  • Devise an embedded default-on management capability.

  • Provide means to support the instantiation and dependable operation of different networks on a single infrastructure in a commercial setting (virtulization).

  • Develop an integrated framework to represent, design, implement and operate network architectures that all belong to a common family of interoperable network instances.

Workpackage 3: Social and commercial control (led by DT)

Understand how architectural features allow a controlled behavior, provide flexibility in terms of technical, social and economical outcomes, and interact with business stakeholders outside Triology to get commercial/strategic steer.

  • Conclusions

  • A clean slate Internet design

  • Requires novel concepts with an out-of-box thinking

  • Needs an experimental facility to experimentally verify that protocols and architectures are viable, scalable and efficient

  • Offers new technical and economical opportunities for operators, but only for early adopters

  • For these reasons, DT is involved in the above projects
