Netflix, iPlayer, YouTube, and the like, are now the dominant sources of
traffic on the Internet. Recent studies observe that competing adaptive
video streaming applications generate flows that lead to instability,
under-utilization, and unfairness in bottleneck link sharing within the
network. Additional measurements suggest there may also be a negative
impact on users' perceived quality of service as a consequence. While it
may be intuitive to resolve application-generated issues at the application
layer, in this presentation I shall demonstrate the merits of a network
layer solution. I will present a new network-layer metric that reflects
user experience. A performance evaluation using our open-source
implementation in the home environment reveals that the network-layer may
just be the right place to attack the general problem.
