Subject: NEW Issue - WS-Discovery - Discovery proxy and multicast
suppression requirement

 

Please defer discussions on this issue until a time this
issue is accepted and is assigned a number.

 

Description:

The current specification requires a Discovery Proxy to
listen and suppress multicast messages on a network. While this is important
for many ad-hoc networks it may not be appropriate in some configuration. For
example, in a completely managed mode where clients and services are configured
with the address of the discovery proxy, there is no need for proxy to listen
and suppress the multicast messages. The proxy may be in the data center, in
the cloud or places where there may not be any multicast traffic.  Many
times a proxy may not have a full view of the network and hence it may not make
sense to suppress every multicast requests. By requiring the proxy to support
multicast suppression prevents implementers of server based discovery to be
compliant with the specification.

 

Proposed Resolution:

The multicast suppression should be not a required for a
proxy. The proxy may choose to listen on one or more multicast networks and
suppress the multicast requests as desired.
