Abstract
A metropolitan area network (MAN) communications method, a metropolitan area server, a node switch, a node server, and a MAN communication system for solving the incapability of an IP network in ensuring transmission quality. The communications method comprises: a piece of MAN equipment accessing a MAN, the metropolitan area server in the MAN allocating for the network accessing equipment a protocol tag and a MAN address; the MAN equipment comprising the node switch and the node server; the protocol tag being used as a description of the connection between the MAN equipment and the metropolitan area server; for each cross MAN service request, the metropolitan area server allocating a data tag of the corresponding service: the data tag being used as a description of the connection among the service node related to the service. This invention is applicable in multimedia transmission, and is capable of ensuring a stable transmission rate, thereby avoiding delays.
