	att_abstract={{Despite its widespread adoption and popularity, the Hypertext
Transfer Protocol (HTTP) suffers from fundamental performance
limitations. SPDY, a recently proposed alternative
to HTTP, tries to address many of the limitations of HTTP
(e.g., multiple connections, setup latency). With cellular networks
fast becoming the communication channel of choice,
we perform a detailed measurement study to understand the
benefits of using SPDY over cellular networks. Through
careful measurements conducted over four months, we provide
a detailed analysis of the performance of HTTP and
SPDY, how they interact with the various layers, and their
implications on web design. Our results show that unlike
in wired and 802.11 networks, SPDY does not clearly outperform
HTTP over cellular networks. We identify, as the
underlying cause, a lack of harmony between how TCP and
cellular networks interact. In particular, we identify a fundamental
flaw in TCP implementations where TCP does not
account for a change in network latencies after an idle period,
as is common in cellular networks. This causes spurious
retransmissions and degraded throughput for both HTTP
and SPDY. We conclude that a viable solution has to account
for these unique cross-layer dependencies to achieve
improved performance over cellular networks.}},
