The SLP daemon maintains a list of all DAs, not just the ones sharing one or more of its scopes.
This list is queried by the library so that it knows what scopes are available in the whole system, and where they are hosted (on which DAs). The library then uses this information to send queries to a subset of DAs directly, according to the scopes in which it has been asked to search. -----Original Message----- From: Roel van de Kraats [mailto:r...@advancedcargo.eu] Sent: 09 December 2010 15:56 To: Morrell Richard (external) Cc: 'openslp-devel@lists.sourceforge.net' Subject: Re: [Openslp-devel] Scope list in SRVRQST On 12/09/2010 04:50 PM, Morrell Richard (external) wrote: > I presume by "DA service requests" you mean queries for > service:directory-agent.

But if a lot of different scopes are used, this causes unnecessary network traffic, because the querying slpd is only interesting in DAs with the same scope(s). Or am I wrong?
