Programmable interface link layer device

摘要

The inventive interface link layer device is connected in-between a first sub network and a long delay link to which at least one second sub network is connected. The interface link layer device comprises at least two storage means, whereby new configuration data received via the long delay link is written to one of said storage means to simulate the devices of the second network within the first network. As long as the configuration information is not complete yet, the respective other storage means are accessed in case a self ID phase is initiated. In case a self ID phase is initiated as soon as or after the new configuration data is complete, the storage means to which the new configuration data has been written is used for setting up the self ID packets.
