WS-Discovery at OASIS
WS-Discovery
is one of those few WS-* protocols that fills a very special gap in today's
distributed programming scenarios. WS-Discovery
proposes a lightweight, non-centralized mechanism for dynamically discovering
services in a distributed environment. Its applicability is especially important
on sensors and devices networks where nodes change location constantly. Typically, WS-Discovery
is used in combination with UDP in order to broadcast discovery messages to
different nodes.
In recent days, OASIS formed a new committee
for defining a subset of the WS-Discovery set of specifications that can be
applied on control devices. I am more
and more skeptical about the work on WS Standards lately, but I think this committee
can have a positive impact in the adoptions of WS-Discovery.
