Patent attributes
A method and apparatus are proposed for dynamically allocating units of user data to resource devices when the user data is transmitted in small packets multiplexed onto long packets and both the long and short packets contain routing information relating to each unit of user data. In the arrangement A mapping table is provided containing identifiers that identify a group of resource devices. A receiving unit extracts routing information from the long packets. For each unit of data, a first bit sequence of the routing information is used to address the table and obtain a group identifier. Subsequently, a second bit sequence taken from the routing information is concatenated onto the group identifier obtained to generate a resource identifier identifying a single resource device. The mapping table is preferably implemented as a writable RAM or portion of the same.
