WG info: current charter, status page.
Mailing list: alto@ietf.org (archives)
Chairs: Enrico Marocco <enrico.marocco@telecomitalia.it>

Agenda:
- Administrivia / Status (Chairs, 10')
- Deployment considerations (Michael Scharf, 10')
draft-ietf-alto-deployments-09
- Rechartering discussion (WG / Chairs / AD, 60')
Work items under consideration:
o (Standards Track) Protocol extensions for reducing the volume of
on-the-wire data exchange required to align the ALTO server and
clients. Extensions under consideration are mechanisms for
delivering server-initiated notifications and partial updates
of maps. Efforts developed in other working groups such as
Websockets and JSON-path will be considered, as well as bespoke
mechanisms specific to the ALTO protocol. (18')
o (Standards Track) Extensions to the base ALTO server discovery
mechanism (RFC-to-be) for deployment in heterogeneous network
environments. Mechanisms under consideration are extensions for
third-party and anycast-based server discovery. (5')
o (Standards Track) Protocol extensions to convey a richer set of
attributes to allow applications to determine not only "where"
to connect but also "when" to connect. Such additional information
will be related both to endpoints (e.g. conveying server load
and cache geolocation information for CDN use cases) and to
endpoint-to-endpoint costs (e.g. bandwidth calendaring to represent
time-averaged cost values in datacenter networks). (19')
The working group will specify such extension in coordination with
other working groups that are also working on the related use
cases (e.g. cdni, i2rs, lmap).
o (Informational) A survey of techniques to formalize the structure
of a network graph (that can derived from a set of related ALTO
network and cost maps) in a format that would facilitate advanced
graph computation. Such survey will cover both models used in
popular open-source software (e.g. NetworkX, Blueprints) and models
being considered in other working groups (e.g. netmod, i2rs). (18')
