Ditto Protocol topic structure for connections
A valid topic consists of four elements, describing the connection affected by this message and the type of the message:
_/<connectionId>/connections/announcements/<subject>
_
: empty field.connectionId
: the ID of the connection.group
: the group for addressing connections isconnections
.criterion
: the type of protocol messages addressing connection announcements isannouncements
.subject
: for announcements thesubject
contains the announcement name
Note: The topic path of the connections group does not contain a namespace since there is
no correlation between namespaces and connections. Also there is no channel unlike the things group.
