Abstract:
The ALTO base protocol [RFC7285] is based on HTTP/1.x, focusing on
the simple, sequential request-reply use case, in which an ALTO
client requests a sequence of information resources, and the server
sends the complete content of each information resource to the client
one by one. ALTO/SSE [RFC8895] defines a new transport design to
allow an ALTO client to request the monitoring of multiple resources,
and the server can then continuously, concurrently, and incrementally
push updates whenever monitored network information resources change.
But ALTO/SSE assumes an HTTP/1.x setting, and essentially designs a
new concurrent transport protocol on top of a sequential HTTP/1.x
connection, but newer versions of HTTP (e.g., HTTP/2 [RFC7540])
already support concurrent, non-blocking transport of multiple
streams in the same HTTP connection. This document introduces the
ALTO transport information publication service (TIPS), which allows
the naming of individual incremental updates to multiple ALTO
information resources and the distribution of the naming, enabling
ALTO to take advantage of newer HTTP versions. In particular, it
gives an ALTO client the new capability to explicitly request (pull)
a specific incremental update. It also provides an ALTO server the
new capability to push a specific incremental update using native
HTTP/2 or HTTP/3 server push. This document defines TIPS as a
service, independent of client pull or server push. A companion
document [draft-schott-alto-new-transport-push] defines server-push
ALTO transport based on ALTO TIPS.
