The stability of FAST TCP is studied in this paper based on a discrete-time model. We prove that FAST TCP is locally asymptotically stable for arbitrary network in the absence of feedback delay. When feedback delay is present, we derive a sufficient condition for local asymptotic stability for the case of a single link. The condition suggests that local stability depends on delays only through their heterogeneity.
