摘要
This system detects and corrects looping problems in a publish-subscribe messaging network. This system requires a token which uniquely identifies a node in this network or universally unique in this messaging network. This system maintains a list of Universally Unique Identifiers (UUID) as a metadata attached to each publish-subscribe message (“publication”). As a node forwards a publication to another node, it is required to append its own UUID to this list or discard the message if its UUID already is in the attached list. Several nodes could form a broker cooperative aggregate node and have a unique identifier for all the nodes in the cooperative if they have an internal mechanism for preventing publication looping.
