21 * @file ats/test_ats_api_scheduling.c
22 * @brief test automatic transport selection scheduling API
23 * @author Christian Grothoff
24 * @author Matthias Wachs
28 * - extend API to get performance data
29 * - implement simplistic strategy based on say 'lowest latency' or strict ordering
30 * - extend API to get peer preferences, implement proportional bandwidth assignment
31 * - re-implement API against a real ATS service (!)
