SYSTEM AND METHOD FOR TRANSLATION OF VIRTUAL LAN IDENTIFIERS

摘要

Systems comprising aggregation equipment (1) and remote equipment (2-3) for exchanging messages between a subscriber unit (4,5,6,7,8,9) of the subscriber equipment (4-9) and the aggregation equipment (1) via a remote unit (2,3) of the remote equipment (2-3) are provided with translation equipment (12) for translating at least one virtual local area network identifier in at least one of the messages. As a result, it is no longer necessary to configure the remote equipment (2-3) to distribute the available virtual local area network identifiers among the remote equipment (2-3). A generator (44) generates translations of virtual local area network identifiers in a static way, to distribute the available virtual local area network identifiers among possible messages coming from the remote units (2,3), or in a dynamic way, to distinguish messages comprising the same virtual local area network identifier and coming from different subscriber units (4,7) and arriving via different remote units (2,3) at the same piece of aggregation equipment (1).
