  We quantify, over inter-continental paths, the ageing of TCP packets,
throughput and delay for different TCP congestion control algorithms containing
a mix of loss-based, delay-based and hybrid congestion control algorithms. In
comparing these TCP variants to ACP+, an improvement over ACP, we shed better
light on the ability of ACP+ to deliver timely updates over fat pipes and long
paths. ACP+ estimates the network conditions on the end-to-end path and adapts
the rate of status updates to minimize age. It achieves similar average age as
the best (age wise) performing TCP algorithm but at end-to-end throughputs that
are two orders of magnitude smaller. We also quantify the significant
improvements that ACP+ brings to age control over a shared multiaccess channel.
