Packet assembly at the network edge is one solution to reduce the high packet rates in core network switches. For this, specialized edge nodes called Assembly Units are needed that assemble client packets into containers and vice versa. In this paper we present the detailed architecture and implementation of a generic Frame Assembly Unit for the Frame Switching architecture along with the testbed used for validation. Our design supports timer and threshold based assembly including packet fragmentation for fixed and variable size container frames at 10 Gbps per direction. For assembly and packet delineation we use the ITU-T Generic Framing Procedure. We report performance and implementation results for an overall design that operates with a 128 Bit data-path at 100 MHz on Xilinx Virtex4 FPGAs.
