A 3-minute introduction to Dynam-IX

Talk at RIPE 76 by Marco Chiesa

Problem

Autonomous Systems (ASes) can now reach hundreds of networks directly through Internet eXchange Points (IXPs). Despite the benefits, any pair of ASes needs first to agree on exchanging traffic. Such process is mainly manual and lengthy. Because of the hassle, ASes miss interconnection opportunities and prefer long-term agreements, even if not matching current Internet traffic dynamics.

Approach

To improve wide-area traffic delivery performance Dynam-IX enables IXP members with a protocol to find interconnection opportunities and establish interconnection agreements, a high-level interconnection intent abstraction to express peering policies, a legal framework to digitally handle contracts, and a distributed tamper-proof ledger to allow ASes to cooperatively build trust.

Motivating Scenarios

Dynamic interconnection agreements will bring benefits in different scenarios.

Congestion/Reachability. Network operators can use Dynam-IX to establish short-term agreements to deal with aperiodic events that are causing congestion or reachability issues on their networks.

Faster port utilization. The interconnection intent abstraction allows network operators to establish bilateral interconnection agreements over the IXP infrastructure easily. Thus, enabling a quicker approach to start fully utilizing the capacity of their IXPs ports.

Economics. Providers can increase their revenue by efficiently deploying new agreements and reaching new customers, while customers may leverage Dynam-IX to reduce their interconnection costs by adapting their agreements more frequently.
