| Summary:
Despite efforts from cloud and content providers to lower latency to
acceptable levels for current and future services (e.g., augmented reality or
cloud gaming), there are still opportunities for improvement. A major reason
that traffic engineering efforts are challenged to lower latency is that the
Internet’s inter-domain routing protocol, the Border Gateway Protocol, is
oblivious to any performance metric, and circuitous routing is still pervasive.
In this work, we propose two implementation modifications that networks can
leverage to make BGP latency-aware and reduce excessive latency inflation.
These proposals, latency-proportional AS prepending and local preference
neutralization, show promise towards providing a method for propagating
abstract latency information with a reasonable increase in routing overhead.
