Abstract

This paper reveals the performance anomaly (i.e., the decline of delivery speed) when the client upgrades a task from single-source content delivery to multi-source content delivery. This anomaly is mainly caused by two aspects: (1) data sources with different types vary greatly in terms of acceleration reward (AR), and data sources with certain types are particularly easy to become inferior; (2) When the data sources remain fixed for a period of time, the large diversity of participant time (DPT) of data sources disturb the acceleration and the data sources with less participant time are inferior. Combing these insights, we figure out that the multi-source content delivery is limited by the so-called cask effect, i.e., the acceleration effect mainly depends on the inferior data sources.
