Abstract:
The ALTO base protocol [RFC7285] is based on HTTP/1.x, designed for
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. To support the use case that an ALTO client can monitor
multiple resources at the same time and the ALTO server sends only
their updates, the ALTO Working Group introduced ALTO/SSE [RFC8895],
which defines a new, SSE-based multiplexing protocol on top of
HTTP/1.x, to allow the server to concurrently, and incrementally push
updates to the client whenever monitored network information
resources change. However, 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 (i.e., assigning resource identifiers to)
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 the complete server-
push ALTO transport based on ALTO TIPS.
