Abstract:
The IETF ALTO protocol provides guidance to content delivery
applications such as P2P or Content Delivery Networks (CDN), which
have to select one or several hosts or endpoints from a set of
candidates that are able to provide a desired data resource. This
guidance shall be based on parameters that affect performance and
efficiency of the data transmission between the hosts, for instance
the topological distance or the routing cost between them. To this
end, ALTO Servers deployed by Network Operators (NO), provide
requesting ALTO Clients with information, currently such as the NO-
centric view on the network topology, the candidate application
endpoints with attributes such as their connectivity type.
The present draft proposes to extend the cost information provided by
the ALTO protocol by providing, for a same cost metric, several
possible cost values. Which value to provide depends on qualitative
criteria as opposed to quantitative criteria such as time. The
purpose is to allow a finer grained decision on which application
endpoint or sub network to access given that their routing cost
values may depend on criteria suh as the access technology of the end
system consuming the resources or the policy applied for the client
requesting ALTO information.
