Abstract

A technique for providing network access in accordance with at least one layered network access technology comprising layer 1 processes and layer 2 processes is described. In a device implementation, the technique comprises a shared memory adapted to store at least layer 1 data and layer 2 data as well as a memory access component coupled to the shared memory and comprising a first client port adapted to receive memory access requests from a layer 1 processing client and a second client port adapted to receive memory access requests from a layer 2 processing client. The memory access component is configured to serve a memory access request from the layer 1 processing client with a lower priority than a memory access request from the layer 2 processing client. In particular, the memory access component may be adapted to prioritize reading of layer 1 data by the layer 2 processing client over writing of layer 2 data by the layer 1 processing client.
