A DRAM/SRAM memory scheme for fast packet buffers García Vidal, Jorge March, Maribel Cerdà Alabern, Llorenç Corbal San Adrián, Jesús Valero Cortés, Mateo Àrees temàtiques de la UPC::Enginyeria de la telecomunicació::Telemàtica i xarxes d'ordinadors Routing (Computer network management) Router architecture Packet buffers High-performance memory systems Storage schemes Encaminadors (Xarxes d'ordinadors) We address the design of high-speed packet buffers for Internet routers. We use a general DRAM/SRAM architecture for which previous proposals can be seen as particular cases. For this architecture, large SRAMs are needed to sustain high line rates and a large number of interfaces. A novel algorithm for DRAM bank allocation is presented that reduces the SRAM size requirements of previously proposed schemes by almost an order of magnitude, without having memory fragmentation problems. A technological evaluation shows that our design can support thousands of queues for line rates up to 160 Gbps.
