Title : ALTO Incremental Updates Using Server-Sent Events (SSE)

Abstract:
The Application-Layer Traffic Optimization (ALTO) [RFC7285] protocol
provides network related information, called network information
resources, to client applications so that clients can make informed
decisions in utilizing network resources. For example, an ALTO
server can provide network and cost maps so that an ALTO client can
use the maps to determine the costs between endpoints when choosing
communicating endpoints.
However, the ALTO protocol does not define a mechanism to allow an
ALTO client to obtain updates to the information resources, other
than by periodically re-fetching them. Because some information
resources (e.g., the aforementioned maps) may be large (potentially
tens of megabytes), and because only parts of the information
resources may change frequently (e.g., only some entries in a cost
map), complete re-fetching can be extremely inefficient.
This document presents a mechanism to allow an ALTO server to push
updates to ALTO clients, to achieve two benefits: (1) Updates can be
immediate, in that the server can send updates as soon as they are
available; and (2) updates can be incremental, in that if only a
small section of an information resource changes, the server can send
just the changes.
