3.1.4.4 ProbeMatch

  • Article

A server of the BITS Peer-Caching: Peer Discovery Protocol sends a Probe-Match message after it receives a Probe message that matches the server's WS-Discovery type and scope.

The format of the Probe-Match message is as specified in [WS-Discovery] section 5.3. The following additional constraints are placed on the /s:Envelope/s:Body/d:Probe-Match element:

  • The a:EndpointReference child element MUST conform to section 2.2.3 of this document. It MUST contain exactly one msbits:Fqdn child element and exactly one msbits:version child element. These elements carry metadata about the server, even though they are child elements of the a:EndpointReference child element, and SHOULD NOT be copied into subsequent messages addressed to the Endpoint Reference in question.

  • A single d:Types child element MUST be present and include the type "msbits:PeerServer".

  • A single d:Scopes child element MUST be present and contain at least one scope conforming to section 2.2.3 of this document. <6>

  • A single d:XAddrs child element MUST be present and its URI list MUST contain at least one address in the subnet to which the message is sent.<7>
