Device for associating of VLAN markings with data transmission block

摘要

The arrangement has a circuit for allocating a virtual LAN (VLAN) marking to a data transfer block, which includes a marking information memory, a data transmission block memory, a search circuit and a marking circuit. The circuit contains a memory (110) with an addressable content that stores marking information containing reference data and associated markings. A data transmission block memory (120) stores at least part of a data transmission block. A search circuit (130) reads the data transmission block information, searches for reference data corresponding to the information and reads a corresponding subset of the associated marking data. A marking circuit (140) writes a VLAN marking into the data transfer block memory including the corresponding subset An Independent claim is also included for a method of allocating VLAN markings to a data transmission block.
