摘要： This invention relates to the multicast field and discloses a method, system and apparatus for distributing labels for multicast services. The method of this invention is to deploy a primary controller in the network to manage the label space on a centralized basis; the primary controller distributes a label for the multicast service upon obtaining a request for a label from the multicast service source, which ensures that unicast services and multicast services use different labels, thus solving conflicts between unicast labels and multicast labels and between multicast labels; the primary controller can also query labels for multicast members. The apparatus for distributing labels provided in an embodiment of this invention includes a message interaction unit, a information maintenance unit and a label distribution unit.
