Multipath Policies

Multipath policies expose control over aggregation

to users and network operators

Users

- Trade cost & performance

- Per-app / per-connection basis

Operators

- Improve performance of preferred services

- Offer service classes (gold, silver, …)

- New pricing and resource allocation

(Mockup App Operation)


SDN-like approach to coordinate client access to multipath

Central planner optimizes for two objectives:

- Maximize aggregate network capacity

- Provide differential service to users

Leads to more desirable resource allocation than naïve multipath
